Until relatively recently the demand for skins was met exclusively from the hunting of wild populations, but in the last few years a great expansion has taken place in the farming of crocodilians. The earliest so-called "farms" were undoubtedly for the purpose of public display, more in the nature of zoos, and many today still fulfil this role. However farming for the commercial production of skins is increasingly being practised. Some farms also sell crocodile meat and, as in Taiwan, this may occasionally provide the major source of income. The reasons for the rise in popularity of the farming of crocodilians are difficult to assess, but they undoubtedly include the reduction in the supply of wild skins. In part this has been due to a decline in wild populations through over-hunting, persecution and habitat destruction, but legal controls may have been more important. Chief amongst these is the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The majority of crocodilians are in Appendix I of CITES (see Table 1) which means that nearly all commercial trade between party nations is prohibited unless the specimens derive from captive-bred populations. Since the Convention came into force, in 1975, the efficacy of the controls on trade has been increasing as more countries have become party to the Convention and as enforcement procedures have improved. The demand for the higher value "classic" crocodilian skins, especially those of Crocodylus niloticus and Crocodylus porosus, has remained high and, as other legal sources of skins have been shut off, farming appears to have prospered. This directory of crocodilian farming operations was compiled partially to assist in the enforcement of CITES controls, by identifying captive-breeding operations and so-called "farms" which are not breeding crocodilians, and also to ascertain the extent of farming so that its effect on crocodilian conservation can be assessed. It attempts to list all commercial crocodilian farms, giving details of their stock, production, breeding success and husbandry. The survey was designed primarily to locate commercial farming operations but large conservation-orientated crocodilian-breeding centres have also been included, partially because some may develop into commercial farms in the future. Proposed plans for commercial farming have also received attention for the same reason. In this directory the term "farm" has been used to denote any operation rearing crocodilians in captivity; it therefore includes both ranches, which obtain stock from the wild, and captive-breeding operations. Crocodilians are kept, and regularly breed, in zoos around the world, but these have not been considered. It must be stressed that the listing of a farm in this directory does not in any way imply that the farm meets’ the requirements of CITES for recognition as a captive-breeding operation. This function is fulfilled by the register of such operations Introduction Maintained by the CITES Secretariat, as explained in the following section. CITES controls on trade Because CITES controls are so important to the understanding of the farming of crocodilians, and because so much confusion surrounds their interpretation, the following section is provided as a summary of the requirements in relation to trade in crocodilian products. All trade involving countries party to the Convention is subject to the terms of the Convention unless it involves products acquired prior to the Convention's coming into force or unless the country holds a reservation for the species involved, in which case it is treated as a non-Party. Countries currently holding reservations on crocodilians are shown in Table 1. Other countries, notably Italy and France, have held reservations in the past, but these have now been withdrawn. All crocodilians are afforded protection under the Convention by being listed in either Appendix I or Appendix II. Appendix I lists those taxa which are threatened with extinction which are, or may be, affected by trade. Virtually all international trade in these species is prohibited unless’ the exporting Party grants an export permit. This may only be done if the trade is not detrimental to the survival of the wild population and if a permit has been issued by the importing Party stating that the animals or products are not to be used for primarily commercial purposes. There are few exceptions to this, the major éne being if the animals traded derive from populations bred in captivity in accordance with the conditions described below. Such animals are treated as being in Appendix II. Appendix II lists those taxa in which trade must be subject to strict regulation in order to prevent them, or similar species in the list, becoming threatened with extinction in the future. Trade is therefore permitted only when the exporting country issues an export permit indicating that the trade is not detrimental to the survival of the wild population. Countries which are party to the Convention must treat non-party states more or less as if they were also Parties. In other words, if a trader in a party state wants to import a species in Appendix II from a non-Party then he must obtain a CITES-equivalent export permit. Captive-breeding The conditions under which specimens of an Appendix I species may be considered "captive-bred" were defined at the CITES Meeting in San José, Costa Rica, in 1979 and are set out in CITES Resolution Conf. 2.12. Briefly these state that: 2 Introduction 1. Animals may only be traded as captive-bred if they are born in captivity and are the offspring of parents which mated in captivity (or a "controlled environment"). 2. The parental breeding stock must be (i) obtained in a manner not detrimental to the survival of the species in the wild; (ii) maintained without augmentation from the wild population except for occasional introductions for the purposes of genetic improvement; and (iii) managed in a manner which has been demonstrated to be capable of reliably producing second generation captive-bred offspring. It should be noted that second generation offspring do not actually need to have been produced on the farm provided it is using a husbandry technique which has been demonstrated elsewhere to have been capable of producing such offspring. Register of captive-breeding operations These regulations are open to abuse by unscrupulous dealers who merely collect animals from the wild and sell them, claiming that they were captive-bred. There is therefore a need for an authoritative register of approved operations which are producing captive-bred Appendix I species. This need was recognised at the CITES Meeting in Gabarone, Botswana, in 1983 when a Resolution (Conf. 4.15) was adopted recommending that commercial trade in cantive-bred Appendix I species should only be permitted from operations which are registered with the CITES Secretariat. Registration is achieved when the CITES Management Authority in the country of origin reports to the Secretariat details of the farm (specified in CITES Notification to the Parties No. 233, 13 October 1983) and confirms that it complies with conditions set out in Resolution Conf. 2.12. At the date of going to press there are only five registered operations breeding Appendix I crocodilians, one in Madagascar, one in Queensland, Australia, one in Thailand, and two in South Africa. Ranching It has been recognised that some populations of species in Appendix I have recovered as a result of conservation, and are now no longer endangered. They may be capable of sustaining a controlled level of exploitation, and indeed may even benefit from it. A procedure was therefore recommended at the CITES Meeting in New Delhi, India, in 1981, whereby populations of species in Appendix I which would benefit from ranching could be transferred to Appendix II (Conf. 3.15). Ranching is defined as the rearing in a controlled environment of specimens taken from the wild, for the purposes of trade. In order to be eligible, the ranching scheme must be beneficial to the wild population and the products of it must be marked so that they may be distinguished from the products of other populations of the same species in Appendix I. It should be noted that, as there is potentially a continuous interchange between the ranch-reared and wild populations in the 3 Introduction country, they are treated identically in the eyes of CITES and may both be traded. It is up to the local Management Authority to set regulations which differentiate between ranch-reared and wild-caught products. However a Resolution adopted in 1985 (Conf. 5.16) now requires that any conditions specified in the original ranching proposal must be observed by all Parties trading in specimens from the ranched population. Thus since the Australian proposal for ranching C. porosus states that the sale of skins from animals which have not been kept on a ranch for at least one year is prohibited, other Parties should not accept imports of such skins. The population of C. niloticus in Zimbabwe was transferred to Appendix II in 1983 as a result of a ranching scheme, and the population of C. porosus in Australia was transferred in 1985 under a similar scheme. A further Resolution was adopted at Buenos Aires in 1985 on the trade in ranched specimens which recommended, among other things, that ranched products should not be exported to non-Parties nor to Parties holding reservations on the ranched species, and that imports of ranched products should not be accepted from such states. Some of the ramifications of this are that exports of ranched C. porosus skins should not be permitted from Australia to Singapore, as it is a non-Party, nor to Japan, as it has a reservation on this species. The Meeting at Buenos Aires, Argentina, was notable for a change in the procedure for transferring, from Appendix I to Appendix II, those species which had been listed in Appendix I before the agreement of scientific criteria for so doing, and which could withstand some exploitation. The new procedure involves the setting of a quota for each country wishing to trade in these species, in conjunction with an approved management plan. Under this procedure, the populations of C. niloticus in nine African countries listed in Table 2 were transferred to Appendix II with the quotas indicated. The population of C. porosus in Indonesia was transferred to Appendix II with an annual quota of 2000 skins, although in this case the population is still endangered (204). Ranching programmes have many advantages over direct harvesting in that they permit a greater offtake from a given wild population, they produce higher quality skins and they are easier to police. They are, however, more difficult to set up and are more capital-intensive. It is therefore ironic that the developments at Buenos Aires have removed some of the economic advantages of establishing ranching programmes for Appendix I species, in that their potential markets are now restricted, while the quota system for transferring populations to Appendix II is permitted greater flexibility of marketing. METHODS The survey was undertaken during 1983 and 1984. The CITES Secretariat sent a Notification to all CITES Parties of the need to register all commercial captive-breeding operations involving Appendix 4 Introduction I species. The Wildlife Trade Monitoring Unit also approached the wildlife management authorities of non-CITES governments. Contact was made with members of the SSC Crocodile Specialist Group, with crocodile farmers associations and with other individuals knowledgeable on the subject. Wherever possible, questionnaires were sent to the farms themselves requesting details of their stocks, breeding, wild capture, commercial production and husbandry. The results presented in this paper are drawn from the responses to these enquiries and also from published and unpublished material and press reports. In the directory the results are arranged by country. RESULTS AND DISCUSSION The countries and species mentioned in the text are listed in Table 3, which also indicates where commercial operations are found. The species most widely farmed are C. niloticus and C. porosus: this partially reflects their widespread distribution, but also the value of their skins, as they are both highly esteemed by the skin industry. The numbers of the main species kept on commercial farms are shown in Table 4, where it can be seen that Alligator mississippiensis is probably the most numerous species although C. niloticus and Cc. porosus are kept in similar numbers, and the data on these species are less complete. The total number of farms is shown on Table 5 together With other data relating to their production. There are thought to be other farms, for instance in Singapore and Malaysia, for which details were not obtained. Of the 152 farms known in 1985 fewer than 20 were in existence in 1974, and all the indications are that the rapid growth is continuing. The total crocodilian stock of 161 603 is also evidently growing. Recruitment from the collection of wild animals and captive breeding is running at some 72 000 a year. As would be expected from such a young industry, skin production is relatively low while farmers are apparently attempting to build up their stocks. Prior to 1979 when the farms in Papua New Guinea started production the only appreciable quantities of skins being sold from farms originated in Zimbabwe. This survey has shown that at least 14 769 farm skins were marketed in 1983/84. If it is assumed that the Majority of the recruitment to farm stocks is to be slaughtered in four years time, then production might rise to 60 000 by 1989, although it is unlikely that the growth will be so fast. Finances Although legislative controls on hunting wild crocodilians undoubtedly play an important part in generating favourable conditions for the establishment of farms, the factor which will ultimately determine their continued survival is their financial success. Commercial companies are understandably reluctant to release their accounts for scrutiny, and so it is difficult to assess their profitability. In addition most farms are currently in the development phase and would consequently be expected to be in negative cash balance 5 Introduction until they reach full production. As a starting point it therefore seems reasonable to examine first the oldest-established farms. One of the oldest farms in the world is the Samutprakan farm in Thailand. In 1983 this was said to have a stock of some 30 000 crocodilians, but produced only 200 skins. It could clearly not have been financially viable purely on skin sales, but the operation derives the major part of its income from tourists and claims to be self- financing on this basis. The farms in the USA similarly have a poor stock/production ratio, although they also sell meat as well as skins which may help to boost their profits. Some farms generate additional income by selling livestock to other farmers and some also rely partially on tourist income. A recent analysis (96) suggested that value of an animal at slaughter was US$200-300 while production costs including feeding, labour and hatchling acquisition, were US$85-110. This gives a calculated profit, after allowing for a 10% mortality, of US$80-192 for each animal. Set against this are the capital investment costs, estimated to be US$50 000-200 000 (40), the interest on which would be worth some US$5000-20 000 a year for four years, before any production took place. On the most pessimistic estimates a farmer would therefore need to sell 345 animals merely to pay off his interest before starting to recoup any of his initial investment. The growth in the number of farms in the USA was slow until 1982 and it has been suggested that the chief reason for farming was an interest in alligators, which could be indulged only by _ rich individuals not unduly interested in swift profits (123). However the rapid increase in the last two years in the number of farmers, particularly in Florida, suggests that substantial profits are expected, if not yet realised. This may be associated with the increasing availability of hatchlings from wild-collected eggs from Louisiana Rockefeller Refuge and, particularly, the Florida supplement programme. The farms in Zimbabwe also benefit from a _ state-run egg collection programme and Magnusson (123) attributes their apparent profitability to cheap labour and a plentiful supply of cheap protein food for the crocodiles, both of which he suggests may decline in the future. Several of these farms also derive a substantial part of their income from tourists and the sale of curios (179). The crocodile ranching industry in Papua New Guinea provides a model which other countries are attempting to emulate and which contributes the bulk of the world production of farmed skins (Table 5). Although many of the small farms initially established have been discontinued, those that survive are apparently capable of running at a profit, almost exclusively on skin sales (85). An analysis of the proposed ranching industry in Australia, also using C. porosus, estimated that total acquisition and rearing costs per hatchling were A$35-55 to a slaughter size of 5-6 ft (1.52-1.83 m), at which point the skins were valued at A$150-180 (192). 6 Introduction It is clear that the captive-breeding of crocodilians requires more money, both in terms of the running costs of maintaining broodstock and in the initial capital outlay required to install breeding facilities, than the rearing of wild-caught eggs or young. Magnusson (123) has pointed out that the majority of the financially successful operations depend on wild populations of crocodilians for the bulk of their rearing stock. It is therefore slightly surprising that the farms in Zimbabwe and the USA are breeding increasing quantities of their own stock, and breeding is being investigated more seriously in Papua New Guinea. One possible explanation is that many captive-breeding operations rely, at least partially, on tourist income. Indeed the needs of tourists and of breeding facilities are similar, both requiring large, mature animals and semi-natural ponds; and the large sums invested in new tourist-orientated farms indicate that the financial backers, at least, anticipate making money from this type of venture. Crocodilian farming and its impact on conservation Controversy has raged over whether or not the farming of crocodilians may be desirable on conservation grounds. The arguments for and against farming may be summarised as follows: Diversion of trade Given that there is a market for crocodilian products which otherwise would be supplied by hunting wild populations, the availability of the same products from farmed stock may meet some of the demand and reduce the need for hunting. Whether this works in practice or whether farmed products merely add tc the size of the market, iS open to debate. The chief effect is likely to be economic, by reducing the price of skins and thereby reducing the profit margins of hunting to unacceptable levels. This effect is particularly marked where the hunting operation is poorly managed and the wild population is nearing “commercial extinction". Farmed skins tend to be of higher and more uniform quality than wild-caught ones which gives them a competitive advantage in the market, although they may consequently command a higher price. In contrast it has been suggested that if illegal trade has been successfully reduced by control measures, public demand will also drop. Any renewed stimulation of the market by the introduction of farmed products will increase the demand once more and possibly renew hunting pressure on the wild populations. This effect is likely to be greatest where trade has virtually ceased, in general for species in Appendix I. Both arguments are affected by the relative sizes of the supplies of farm-raised and wild-caught skins. International trade in crocodilian skins has recently been reviewed by Hemley and Caldwell (94) who found that trade in the major species, excluding Caiman crocodilus, reported to CITES was at least 82 000 a year although they cautioned that this was certainly an under-estimate. Farm production of 12 000 skins is already a significant proportion of this market, and its importance is destined to increase. However, the major trade is 7 Introduction undoubtedly in C. crocodilus skins, some 700 thousand reported annually to CITES with the true trade figure probably being in excess of a million (94). Taiwan is the only country farming this species in large numbers, primarily because the low commercial value of the skins means that farming is not economic unless other products can also be marketed. It is therefore unlikely that farming will ever supply a significant proportion of the world market for C. crocodilus, or for crocodilian skins as a whole, unless trade in wild-caught caiman skins is drastically curtailed. Control of trade Control of illegal trade in the products of endangered species is rendered more difficult by introducing legally acquired farmed products into the market. This problem has been addressed by the CITES Resolutions on both captive-breeding (Conf. 2.12) and ranching (Conf. 3.15) which recommend that the products be adequately marked to distinguish them from products of wild-taken animals. However it is still feared that unscrupulous traders may use farms as a front for disposal of illegally acquired, wild-caught skins, either directly from the farm or on re-export from an intermediate country. Several countries with crocodilian farming industries have elaborate licensing and inspection procedures designed to prevent this, but allegations of "laundering" illegal skins have certainly been levelled at some farms. This directory may be helpful in countering this problem as it has attempted to ascertain current stocking levels and breeding success. Any so-called farmed skin production in excess of known capacity or from countries not known to have farms should require further investigation. Effects on wild populations If a species has become depleted or even endangered in the wild, captive rearing may provide protection for a significant proportion of the population. If breeding can also be achieved, the population can be augmented until ultimately it may be possible to reintroduce captive-bred stock to the wild. Several crocodilian breeding operations have undoubtedly achieved this, notably with Crocodylus moreletii, C. intermedius and Gavialis gangeticus, but these are all conservation operations and not intended to be commercial. The only commercial operation currently using a seriously endangered species, Crocodylus siamensis, is the Samutprakan farm in Thailand. The Zapata Swamp farm in Cuba also breeds Crocodylus rhombifer and C. acutus but the degree of commercial involvement of this farm is not known. However it is by no means certain that reintroductions of farmed stock would be desirable because of genetic alteration, either through artificial selection or hybridization. Both the Samutprakan Farm and the Zapata Swamp farm already have substantial populations of hybrid animals. Captive-breeding is seldom completely independent of the wild population and the capture of wild animals is often necessary, if not for direct rearing, at least for the acquisition of breeding stock. Thus even captive-breeding operations usually result in a net drain, albeit small, on the wild stock. A fully developed ranching operation 8 Introduction removes far more animals from the wild but, even if reintroductions are not carried out, one of the chief prerequisites for approval of a ranching scheme under the provisions of CITES Resolution Conf. 3.15 is that it should, on balance, be beneficial to the wild population, although this only affects those species in Appendix I. Habitat and species preservation Crocodilians have in the past been persecuted as vermin, and their swampy habitat is frequently destroyed to make way for "more productive" forms of land use. The demonstrable ability of crocodilians to generate income may help to promote the conservation of healthy wild populations. This is particularly so with ranching, where the whole operation depends on the maintenance of a wild breeding stock, but to a much lesser extent captive-breeding farms may encourage the conservation of wild stock for periodic genetic enhancement. The Maintenance of a wild population of crocodilians necessitates the preservation of their habitat, which benefits the other organisms in the same environment. The financial incentive of crocodilian exploitation therefore also reduces the economic pressure for wetland reclamation. Cultural preservation Crocodilian ranching techniques can be adapted to conditions of village technology suitable for integration in the culture and economy of rural communities. The ranching programmes in Papua New Guinea and Northern Australia have the declared objectives of providing employment for indigenous peoples. Alternative schemes for the generation of income frequently entail far greater technological input and social disruption. Genetic mixing and disease risk Other potential disadvantages include the accidental introduction of non-indigenous species or distinct genetic races from escapes, and the spread of disease from farm to wild stock. THE OUTLOOK In most countries that host a crocodilian farming industry it appears to be growing, in terms of the number of farms, the number of animals and the production of skins. The technical problems of farming have largely been surmounted, but whether this growth continues or whether the industry collapses will depend on its long-term financial Viability. One factor which is of importance to the conservation of crocodilians is the relative reliance on wild-caught animals ("ranching") and on captive-breeding. The total number of animals being bred on farms appears to be increasing, and may now account for some 40% of recruitment to farm stocks each year. At first sight this might seem to be encouraging but this requires further consideration. Captive-breeding has played an important role in the conservation of several seriously depleted crocodilian species, but these have mostly been non-commercial operations. Commercial 9 Introduction captive-breeding, as discussed earlier, does less to further conservation, and it should not be seen, as it often is, as an alternative to habitat conservation. Ranching, on the other hand, may be far more beneficial as it requires the maintenance of a healthy wild population and the habitat which supports it (123). In essence it is little different from a controlled harvest of larger animals for skins; in the USA and Papua New Guinea the two types of exploitation run side by side. Ranching has some advantages over a direct harvest as it may be easier to regulate, particularly if, as in Zimbabwe, the USA and Australia, the collection of eggs is carried out entirely by Government staff or under their close control. The maintenance of a separate ranched stock also provides a degree of insurance in the event of an environmental disaster or breakdown of effective control of harvesting, owing, for instance, to political instability. The cause of crocodilian conservation may therefore best be served, not by a cessation of all wild harvesting and a development of farming, but by the implementation of effective management plans for wild populations, involving ranching, direct harvest, or a combination of the two. The success of any such management plan is entirely dependent on thorough background research to determine existing population levels, and on the ability to conduct the exploitation in a controlled manner. The high levels of illegal trade in crocodilian products (94) suggests that the current degree of control is far from adequate in many parts of the world.

Jusqu'a une époque relativement récente, la demande de peaux était satisfaite exclusivement par la chasse des populations sauvages mais, ces derniéres années, 1'élevage des crocodiliens s'est fortement étendue. Les premiéres "fermes", selon l'appellation qui leur est donnée, ont sans aucun doute été crées 4 l'intention du public, ayant davantage la nature de zoos, et nombre d'entres elles continuent de jouer ce _ rdle. Cependant, 1l'élevage pour la production commerciale de peaux est de plus en plus pratiqué. Certaines fermes vendent aussi de la viande de crocodile et, comme a Taiwan, ceci peut parfois fournir la principale source de revenu. Les raisons de cette popularité accrue de 1'élevage des crocodiliens sont difficiles a @évaluer, mais elles comprennent certainement la réduction apparue dans 1l'approvisionnement en peaux sauvages, Ceci est dl, en partie, au déclin des populations sauvages du fait d'une chasse excessive, de la persécution et de la destruction des habitats, mais les contrdles exercés en application des lois pourraient avoir une plus grande importance encore. En tete de ceux-ci se trouve la Convention sur le commerce international des espéces de faune et de flore sauvages menacées d'extinction (CITES). La majorité des crocodiliens sont inscrits A l1'Annexe I de la Convention (voir Tableau 1), ce qui signifie que presque toutes les transactions commerciales entre les pays Parties sont interdites, 4a moins que les spécimens proviennent de populations élevées en captivité. Depuis l'entrée en vigueur de la Convention, en 1975, l'efficacité des controles du commerce s'est accrue, car davantage de pays en sont devenus Parties et les procédures d'exécution se sont améliorées. La demande de peaux "classiques" de crocodiliens les plus précieuses, tout spécialement celles des espéces Crocodylus niloticus et Crocodylus porosus, est restee forte et, les autres sources limitées de peaux ayant été fermées, 1'élevage parait avoir prosperé. Ce répertoire des @levages de crocodiliens a été @laboré, en partie, pour faciliter l'exécution des controles CITES, en identitiant les élevages et les soi-disantes "fermes" qui ne procédent pas 4 la reproduction, et aussi pour déterminer l'importance de 1l'élevage, en vue d'évaluer ses effets sur la conservation des crocodiliens. 2 | tente d'établir ume liste de toutes les fermes commerciales de ecrocodiliens et donne des informations détaillées sur leur cheptel, leur production, leur réussite en matiére de reproduction et sur les techniques d'élevage. L'enquete a @té congue, en premier lieu, afin de localiser les élevages commerciaux, mais les grands centres de reproduction de crocodiliens orientés vers la conservation y ont aussi été inclus, notamment parce que certains pourraient devenir des @élevages commerciaux 4 l'avenir. Pour la méme raison, l'attention a également été portée sur les projets d'élevages commerciaux. Dans ce répertoire, le terme "ferme" est utilisé pour désigner tout élevage, au sens le plus large du terme, en captivité (soit la détention pendant au moins une certaine période); il comprend donc les ranches dont le cheptel a été prélevé A l'état sauvage et les @levages qui a Introduction pratiquent la reproduction en captivité. Des crocodiliens sont gardés dans des zoos du monde entier, ow ils se reproduisent, mais ils n'ont pas été pris en considération. Il faut souligner que 1'inscription d'un @levage dans ce répertoire n'implique en aucune fagon que la ferme satisfait aux exigences CITES qui lui permettraient d'étre reconnue en tant qu'élevage en captivité. Ce rdle est rempli par le Registre des établissements pratiquant 1l'élevage en captivité tenu par le Secrétariat CITES, ainsi qu'il est expliqué dans la section suivante. Controles CITES du commerce Etant donné l'importance des contrdles CITES pour comprendre le pourquoi de l'élevage des crocodiliens et en raison de la confusion qui régne au sujet de leur interprétation, la section qui suit est rédigée en tant que resumé des exigences relatives au commerce des produits de crocodiliens. Tout le commerce qui concerne des pays Parties a la Convention est soumis aux dispositions de celle-ci, A moins qu'il ne se rapporte 4a des spécimens acquis avant que la Convention soit entrée en vigueur ou a moins que le pays ait formulé une réserve a l'égard de l'espéce en question, auquel cas ce pays est considéré comme un Etat non-Partie. Les pays qui ont formulé des réserves a l'égard de crocodiliens sont mentionnés dans le Tableau 1. D'autres pays, notamment l'Italie et la France, avaient des réserves dans le passé, mais elles les ont maintenant retirées. Tous les crocodiliens bénéficient d'une protection au titre de la Convention, car ils sont inscrits soit a l'Annexe I, soit a 1'Annexe Ele A l'Annexe I sont inscrits les taxons menacés d'extinction qui sont affectés par le commerce, ou qui pourraient l'étre. Pratiquement tout le commerce international de ces espéces est interdit, Aa moins que la Partie exportatrice délivre un permis d'exportation. Ceci ne peut se faire que si le commerce ne nuit pas a la survie de la population sauvage et si un permis a été délivré par la Partie importatrice qui déclare ainsi que les animaux ou les produits ne seront pas utilisés a des fins principalement commerciales. I1 ya quelques exceptions, la principale concernant le commerce d'animaux provenant de populations @élevées en captivité conformément aux conditions décrites ci-dessous. Ces animaux sont traités comme s'ils étaient inscrits a 1'Annexe Il. A l1'Annexe II sont inscrits les taxons dont le commerce doit étre soumis 4 une réglementation stricte ayant pour but d'éviter qu'eux, ou des espéces semblables de cette meme annexe, ne deviennent menaces d'extinction 4 l'avenir. Le commerce n'est donc permis que lorsque le pays d'exportation délivre un permis d'exportation, ce qui signifie que le commerce ne nuit pas a la survie de la population sauvage. 12 Introduction Les payS qui sont Parties 4 la Convention doivent traiter les Etats non-Parties plus ou moins comme s'ils étaient aussi. des Parties. En d'autres termes, si un commergant d'un Etat Partie souhaite importer une espéce de 1'Annexe II d'un Etat non-Partie, il doit obtenir un document équivalent au permis d'exportation CITES. Elevage en captivité Les conditions dans lesquelles des spécimens d'une espéce inscrite a l'Annexe I peuvent étre considérés comme “élevés en captivité" ont été définies lors de la session CITES de San José, Costa Rica, en 1979 et elles sont présentées dans la résolution CITES Conf. 2.12. En bref, elles sont les suivantes: Ve Des animaux ne peuvent étre commercialisés en tant que spécimens élevés en captivité que s'ils sont nés en captivite et sont les descendants de parents s'étant accouplés en captivité (ou dans un "environnement controlé). Qe Le stock parental doit étre (i) obtenu de fagon a ne pas nuire @ la survie de l'espéce 4 l'état sauvage; (ii) maintenu sans augmentation a partir de la population sauvage a l'exception d'apports occasionnels aux fins d'amélioration génétique; et (iii) gérés d'une maniére ayant apporté la preuve qu'elle permet de produire de fagon sre une descendance de deuxiéme génération. Il convient de remarquer qu'il n'est pas nécessaire de produire une descendance de deuxiéme gé@nération dans 1'établissement, A condition que les techniques qu'il applique aient fourni la preuve, ailleurs, qu'elles permettent de produire une telle descendance. Registre des établissements pratiquant l'élevage en captivité Des commergants peu scrupuleux peuvent abuser de ces réglementations en prélevant simplement des animaux a4 l'état sauvage et en les vendant en prétendant qu'ils ont été @levés en captivité. Il est donc nécessaire d'avoir un registre faisant foi des é@levages agrees qui produisent des spécimens d'espéces de l'Annexe I @levés en captivité. Ce besoin fut reconnu a la session CITES de Gaborone, Botswana, en 1983, ow une résolution (Conf.~4.15) a @té adoptée pour recommander que les transactions commerciales touchant les espéces de l'Annexe I @levées en captivité ne soient autorisées que pour des établissements enregistreés aupres du Secrétariat CITES. L'enregistrement est effectif lorsque l'organe de gestion CITES du pays d'origine a transmis au Secrétariat des informations détaillées au sujet de la ferme (information précisées dans la notification aux Parties No. 233 du 13 octobre 1983) et a confirmé qu'elle respecte les conditions présentées dans la résolution Conf. 2.12. A la mise sous presse de ce répertoire, seuls cing établissements @levant des crocodiliens inscrits A l'Annexe I avaient @té enregistrés, un 4a Madagascar, un au Queensland, Australie, un en Thailande et deux en Afrique du Sud. 18 Introduction Elevage en ranch Le fait a @té admis que certaines populations d'espéces inscrites aA 1'Annexe I se sont reconstituées, par suite de mesures de conservation, et qu'elles ne sont plus menacées d'extinction. Elles peuvent 6tre 4 méme de supporter un niveau d'exploitation controlé et, il est vrai, peuvent meme en profiter. C'est pourquoi, une procédure a @t@ recommandée lors de la session CITES de New Delhi, Inde, en 1981, procédure par laquelle des populations d'espéces inscrites 4 l'Annexe I, qui pourraient profiter des effets de 1'élevage en ranch, pourraient étre transférées 4 l'Annexe II (Conf. 3.15). L'élevage en ranch est défini comme étant 1'élevage dans un environnement controlé de spécimens prélevés 4 l'état sauvage, en vue de les commercialiser. Pour pouvoir @tre agréé, l'élevage doit étre favorable a la population sauvage et ses produits doivent @tre marqués, afin qu'il soit possible de les distinguer des produits d'autres populations, de la meme espéce, inscrites a 1'Annexe I. Il convient de noter que, @tant donné qu'un @échange continuel existe potentiellement entre les populations @élevées en ranch et vivant a l'état sauvage dans le pays, elles sont traitées de fagon identique aux yeux de la Convention et peuvent toutes deux faire l'objet d'un commerce. Il appartient 4 l'organe de gestion local d'@laborer les réglementations qui permettent de faire la différence entre les produits provenant d'animaux @levés en ranch et d'animaux sauvages. Cependant, une résolution adoptée en 1985 (Conf. 5.16) demande maintenant que toutes les conditions précisées dans la proposition originale d'élevage en ranch soient observées par toutes les Parties faisant commerce des spécimens de la population @élevée en ranch. Ainsi, @tant donné que la proposition australienne relative 4a l'élevage en ranch de C. porosus stipule que la vente de peaux d'animaux qui n'ont pas été détenus dans un ranch pour au moins un an est interdite, les autres Parties ne devraient pas autoriser l'importation de telles peaux. La population de C. niloticus du Zimbabwe a été transférée 4 1'Annexe II, en 1983, sur la base d'un programme d'@élevage en ranch et la population australienne de C. porosus l'a été, en 1985, sur la base d'un programme du meme genre. Une autre résolution a été adoptée A Buenos Aires, en 1985, au sujet du commerce des spécimens @élevés en ranch. Elle recommande, entre autres, que les produits provenant d'@élevages en ranch ne soient exportés ni vers des Etats non-Parties ni vers des Parties ayant formulé des réserves 4 l'égard des espéces faisant l'objet d'un @élevage en ranch, et que les importations de ces produits en provenance de tels Etats ne soient pas acceptées. Certaines des ramifications de ce qui précéde font que les exportations de peaux de C.°porosus @levés en ranch ne devraient pas @tre autorisées par l'Australie si elles étaient destinées & Singapour, qui n'est pas Partie, ou au Japon, qui a formulé une réserve & l'égard de cette espéce. 14 Introduction La session de Buenos Aires, Argentine, fut remarquable, en ce sens que la procédure pour le transfert, de l'Annexe I A 1'Annexe II, des espéces ayant été inscrites 4 l'Annexe I avant 1l'adoption des critéres scientifiques prévus a cet effet et qui, de toute évidence, peuvent supporter un certain niveau d'exploitation, y a été modifiée. La nouvelle procédure prévoit 1l'établissement d'un quota pour chaque pays souhaitant commercialiser ces espéces, dans le cadre d'un plan de gestion agréé. En vertu de cette procédure, la population de C. porosus de 1'Indonésie a été transférée 4 1'Annexe II avec un quota de 2000 peaux. Les populations de C. niloticus des neuf pays africains Mentionnés au Tableau 2 ont aussi été transférées § 1l'Annexe II avec les quotas indiqués. Les programmes d'élevage en ranch ont de nombreux avantages par rapport a l'exploitation directe, car ils permettent des prélévements plus importants dans une population sauvage donnée, ils produisent des peaux de meilleure qualité et, avec eux, il est plus facile de s'assurer que la réglementation est appliquée. Cependant, il est plus difficile de les mettre sur pied et ils exigent davantage de capitaux. I1 parait donc paradoxal que les décisions prises 4 Buenos Aires aient @liminé certains des avantages économiques des programmes d'élevage en ranch d'espéces inscrites a l'Annexe I - leurs marchés potentiels sont maintenant réduits - alors que le systéme de quotas pour le transfert de populations 4 1'Annexe II bénéficie d'une plus grande flexibilité en ce qui concerne la mise des produits sur le marché. METHODES L'enquéte a été effectuée en 1983 et 1984. Le Secrétariat CITES a envoyé une notification 4 toutes les Parties 4 la Convention au sujet de la nécessité d'enregistrer tous les établissements pratiquant l'élevage en captivité, A des fins commerciales, d'espéces inscrites 4 l'Annexe I. L'Unité de surveillance continue du commerce de la faune et de la flore sauvages a pris contact également avec les autorités competentes en matiére de gestion de la faune sauvage des gouvernements des Etats non-Parties. Des contacts ont aussi ete établis avec les membres du Groupe de spécialistes des crocodiles de la CSE, avec des associations d'éleveurs et avec d'autres personnalités connaissant le sujet. Chaque fois que possible, des questionnaires ont été envoyés aux fermes elles-mémes en vue d'obtenir des informations détaillées sur leur cheptel, sur la reproduction, sur les captures 4 l'état sauvage, sur leur production commerciale et sur leurs techniques d'élevage. Les résultats présentés dans ce document sont tirés des réponses 4 ces requétes, et aussi de matériels publiés et non publiés et de rapports de presse. Dans le répertoire, les résultats sont présentés pays par pays. RESULTATS ET DISCUSSION Les pays et les espéces mentionnes dans le texte sont énumérés au Tableau 3, lequel signale également 1'emplacement des é@établissements. 15 Introduction Les espéces les plus largement élevées dans les fermes sont C. niloticus et C. porosus: ceci est, en partie, le reflet de leur repartition @étendue, mais aussi de la valeur de leurs peaux, puisque toutes deux sont hautement estimées par l'industrie du cuir. Les effectifs des principales espéces détenus dans des fermes a vocation commerciale sont présentés au Tableau 4, ot l'on peut voir qu'Alligator mississippiensis est problablement l'tespéce la plus abondante, bien que C. niloticus et C. porosus atteignent des effectifs du meme ordre de grandeur, les données sur ces espéces @tant pourtant moins complétes. Le nombre total de fermes est indiqué au Tableau 5, ensemble avec d'autres renseignements relatifs a leur production. On pense qu'il existe d'autres fermes, par exemple a Singapour et en Malaisie, mais aucune information a leur sujet n'a pu @étre obtenue. Sur les 152 fermes connues, en 1985, moins de 20 existaient en 1974 et tout porte 4 croire que cette extension rapide se poursuit. Le cheptel en crocodiliens de 161'603 ' s'accroit évidemment aussi. L'augmentation du cheptel du fait de la capture d'animaux sauvages et de la reproduction en captivité atteint environ 72'000 tétes par an. Comme on peut s'y attendre pour une industrie aussi jeune, la production de peaux est relativement faible, les fermiers essayant apparemment de constituer leur cheptel. Avant 1979, alors que les fermes de Papouasie-Nouvelle-Guinée commengaient 4 produire, les seules quantités appréciables de peaux vendues par des fermes provenaient du Zimbabwe. Cette enquéete a montré qu'au moins 14'769 peaux de ferme avaient &té mises sur le marché en 1983/84. Si l'on prend pour hypothése que la plus grande partie de l'accroissement du cheptel des fermes est destiné 4 l'abattage dans un délai de quatre ans, la production pourrait atteindre 60'000 peaux vers 1989, bien qu'il soit peu probable que la croissance soit aussi rapide. Finances Bien que les controles exercés sur la chasse aux crocodiliens, en vertu de l'application des lois, jouent sous aucun doute un role important en créant des conditions favorables a l'établissement de fermes, le facteur qui, en fin de compte, déterminera leur avenir est leur succés financier. Les compagnies commerciales, on peut le comprendre, rechignent a ouvrir leurs comptes pour permettre une étude et, ainsi, il est difficile d'évaluer leur rentabilité. De plus, la plupart des fermes se trouvent actuellement en phase de développement et l'on peut donc s'attendre 4 ce que leur bilan reste négatif tant qu'elles n'auront pas atteint leur pleine production. Pour commencer, il parait donc raisonnable d'examiner de prime abord les fermes les plus anciennes. L'une des fermes les plus anciennes du monde est celle de Samutprakan, en Thailande. En 1983, on disait qu'elle disposait d'un cheptel de 30'000 crocodiliens, mais elle n'a produit que 200 peaux. Financiérement, il est @vident qu'elle ne pouvait survivre du produit de la seule vente des peaux, mais 1l'établissement tirait la majortié 16 Introduction de ses revenus des touristes et elle prétendait s'autofinancer de cette fagon. Les fermes des Etats-Unis d'Amérique, elles aussi, présentent un Mauvais rapport cheptel/production, bien qu'elles vendent aussi bien de la viande que des peaux, ce qui devrait contribuer Aa augmenter leurs benéfices. Certaines fermes créent d'autres sources de revenu en vendant des animaux vivants a d'autres fermes et certaines comptent aussi sur les revenus produits par le tourisme. Une analyse récente (96) indique que la valeur d'un animal a l'abattage est de US$ 200-300, alors que les frais de production, comprenant 1l'alimentation, le travail et l'acquisition de nouveau-nés, atteignent US$~85-110. Cela donne un bénéfice calculé de US$ 80-192 par animal en tenant compte d'une mortalité de 10%. A coOté de cela, il y a les frais du capital investi, estimé entre US$ 50'000 et US$ 200'000 (40), dont les intérets seraient de l'ordre de US$ 5'000 a US$ 20'000 par an pendant quatre ans avant l'entrée en production. Sur la base de l'estimation la plus pessimiste, un fermier devra donc vendre 345 animaux, pour payer ses intéréts, avant de commencer 4 récupérer son investissement initial. L'augmentation du nombre de fermes, aux Etats-Unis d'Amérique, était lente jusqu'en 1982 et on a pensé que la principale raison poussant 4 l'élevage résidait dans l'intérét porté aux alligators, lequel ne pouvait provenir que de personnes aisées et non intéressées a la realisation de bénéfices rapides (123)% Cependant, l'augmentation accélérée du nombre de fermes, ces deux derniéres années, en Floride en particulier, donne a penser que des profits substantiels peuvent @étre espérés, s'ils n'ont encore été réalisés. Ceci peut étre 1ié A l'augmentation du nombre de nouveau-nés, issus d'oeufs recoltés A l'état sauvage, disponibles et provenant du Louisiana Rockefeller Refuge et, tout particuliérement, du programme spécial de la Floride. Les fermes du Zimbabwe benéficient aussi d'un programme officiel de récolte d'oeufs et Magnusson (123) attribue leur rentabilité apparente au fait que la main d'oeuvre est bon marché et que l'approvisionnement en aliments protéiniques pour les crocodiles est peu colteux et abondant, éléments qui pourraient tous deux, selon lui, se réduire A l'avenir. Plusieurs de ces fermes tirent aussi une part importante de leurs recettes du tourisme et de la vente de souvenirs (179)< En Papouasie-Nouvelle-Guinée, l'élevage en ranch des crocodiles constitue un modéle que d'autres pays tentent d'imiter et qui contribue a l'ensemble de la production mondiale de peaux provenant de fermes (Tableau 5). Bien que de nombreuses petites fermes installées initialement aient disparu, celles qui se maintiennent sont apparemment capables de réaliser un benéfice, presque exclusivement sur la vente des peaux (85). Une analyse de l'élevage en ranch en Australie, qui concerne aussi C. porosus, estimait les frais totaux d'acquisition et d'élevage par animal 3 A$ 35-55 pour une taille 4 l'abattage de 5-6 ft (1,52-1,83 m). A ce stade, la valeur des peaux @tait évaluée a A$~150-180 (192). 17 Introduction Il est @évident que l'élevage en captivité des crocodiliens requiert davantage d'argent, tant en ce qui concerne les frais courants de garde du stock reproducteur que les capitaux nécessaires 4 la mise en place des installations de reproduction, que 1l'élevage 4 partir d'oeufs ou de jeunes prélevés a l'état sauvage. Magnusson (123) a mis en évidence le fait que la majorité des @établissements qui ont obtenu des résultats financiers favorables dépendent des populations sauvages pour la plus grande partie de leur cheptel. I1 est donc quelque peu surprenant que les fermes du Zimbabwe et des Etats-Unis d'Amérique fassent de plus en plus d'élevage 4 partir de leur propre cheptel et que la reproduction soit envisagée de plus en plus sérieusement en Papouasie-Nouvelle-Guinée. Ceci peut trouver une explication dans le fait que de nombreux établissements dépendent, en partie tout au moins, des recettes fournies par le tourisme. Une similarité existe véritablement entre ce qui est nécessaire pour Satisfaire les touristes et ce qui l'est pour pratiquer la reproduction, soit des animaux adultes et de grande taille et des bassins semi-naturels; et les sommes importantes investies dans les nouvelles fermes orientées vers le tourisme montrent que les investisseurs espérent, 4 tout le moins, gagner de l'argent en prenant ce genre de risque. L'élevage des crocodiliens et ses effets sur la conservation Le fait de savoir si l'@élevage de crocodiliens est souhaitable du point de vue de la conservation a donné le jour Aa une controverse animée. Les arguments en faveur et contre l'élevage sont résumés comme suit: Diversion du commerce Etant donné qu'un marché existe pour les produits de crocodiliens et qu'il serait autrement approvisionné par la chasse exercée sur les populations sauvages, la mise @A disposition des mémes produits 4 partir d'animaux @levés dans des fermes pourrait satisfaire une partie de la demande et réduire la nécessité de chasser. La question de Savoir si cela se passe ainsi dans la pratique ou de savoir si les produits des fermes n'augmentent pas simplement les dimensions du marche peut étre discutée. L' effet principal devrait vraisemblablement @tre d'ordre économique: en réduisant le prix des peaux, on réduit les marges bénéficiaires fournies par la chasse A des niveaux inacceptables. Cet effet est particuliérement marqué 14 ou la chasse est mal gérée et la population sauvage proche de 1'"extinction commerciale". Les peaux d'élevage tendent a étre de meilleure et de plus uniforme qualité que les peaux sauvages, ce qui leur donne un avantage concurrentiel sur le marché, bien qu'elles puissent, de ce fait, se vendre a un prix plus élevé, En contrepartie, on a émis l'hypothése que si le commerce illicite a @t@ réduit avec succés grace aux mesures de contrdle, la demande de la part du public se réduira également. Toute nouvelle stimulation du marché du fait de l'introduction de produits de fermes augmentera la demande une fois de plus et renouvellera peut-étre la pression, due A la chasse, s'exergant sur les populations Sauvages. Cet effet devrait probablement @tre plus grand 14 ot le commerce a pratiquement cessé, 18 Introduction soit en régle générale en ce qui concerne les especes inscrites 4 1'Annexe I. Les deux arguments sont influencés par l'importance relative des approvisionnements en peaux provenant des fermes et en peaux d'origine sauvage. Le commerce international des peux de crocodiliens a récemment fait l'objet d'une étude par Hemley et Caldwell (94) qui ont trouvé que celui des principales espéces, 4 l'exception de Caiman crocodilus, ayant fait l'objet de rapports CITES atteignait au moins 82'000 animaux par an, bien qu'ils attirent l'attention sur le fait qu'il s'agit certainement d'une sous-estimation. La production fermiére de 12'000 peaux constitue déja une part importante de ce marché et cette importance s'accroitra. Cependant, la majeure partie du commerce concerne sans aucun doute C. crocodilus, puisque les rapports CITES portent sur 700'000 peaux par année et que le nombre réel est probablement supérieur au million (94). Taiwan est le seul territoire sur lequel cette espéce est @élevée en grands nombres et cela surtout parce que la faible valeur commerciale des peaux signifie que l'élevage n'est @conomiquement rentable que si d'autres produits peuvent aussi étre commercialisés. Il est donc peu probable que 1'élevage produise un jour une part importante du marché mondial des peaux de C. crocodilus, ou des peaux de crocodiliens dans leur ensemble, a moins que le commerce des peaux de caimans Sauvages ne soit drastiquement restreint. Controle du commerce Le controle du commerce illicite de produits d'espéces menacées d'extinction est compliqué par l'introduction sur le marché de produits fermiers acquis légalement. Ce probléme a @té abordé par les résolutions CITES sur l'élevage en captivité (Conf. 2.12.) et sur l'@élevage en ranch (Conf. 3.15) qui recommandent le marquage approprié des produits, afin qu'ils puissent 6tre distingués des produits provenant d'animaux prélevés 4 l'état sauvage. Cependant, on peut toujours craindre que des commergants sans scrupules fassent usage de l'existence des fermes pour disposer de peaux sauvages illégalement acquises, soit directement a partir de la ferme, soit par le biais de réexportations A partir de pays tiers. Plusieurs pays ayant des @élevages de crocodiliens ont @élaboré des procédures en matiére de permis et d'inspection dont le but est de prévenir ce genre d'activité, mais des allégations de "“blanchissage" de peaux illicites ont certainement été formulées a l'égard de certaines fermes. Ce répertoire peut étre utile pour contrer ce probléme, puisqu'il tente de fournir le niveau réel des stocks actuels et de faire état des réussites effectivement obtenues en ce qui concerne la reproduction. Toute production de peaux dites fermiéres qui dépasse la capacité de production reconnue ou qui provient de pays qui n'ont pas la réputation de disposer de fermes devrait faire l'objet d'une enquéte complémentaire. Effets sur _ les populations sauvages Si une espéce voit ses effectifs diminuer ou si elle devient menacée d'extinction A l'état sauvage, l'élevage en captivité peut avoir un effet protecteur pour une partie importante de la population. Si la reproduction peut aussi étre assurée, la population 19 Introduction peut @6tre accrue jusqu'au point ot il peut @tre possible de réintroduire des animaux reproduits en captivité dans la nature. Plusieurs @tablissements pratiquant la reproduction de crocodiliens sont sans aucun doute parvenus 4 ce stade, notamment avec les espéces Crocodylus moreletii, C. intermedius et Gavialis gangeticus, mais il s'agissait toujours d'établissements orientés vers la conservation et sans intentions commerciales. Le seul établissement commercial utilisant actuellement une espéce sérieusement menacée d'extinction, Crocodylus siamensis, est la ferme de Samutprakan en Thailande. La ferme des marais de Zapata Aa Cuba pratique aussi la reproduction de Crocodylus rhombifer et de C.-acutus, mais on ne sait pas 4 quel point cette ferme est concernée par le commerce. Cependant, il n'est~-en aucune fagon certain que les réintroductions d'animaux fermiers soient souhaitables, A cause de leur altération génétique due soit a une sélection artificielle soit a l'hybridation. La ferme de Samutprakan et celle des marais de Zapata possédent dé@éja des cheptels substantiels d'animaux hybrides. L'élevage en captivité est rarement totalement indépendant de la population sauvage et la capture d'animaux sauvages est souvent nécessaire, sinon pour les @lever directement, du moins pour l'acquisiton du stock reproducteur. Ainsi, meme les établissements assurant la reproduction en captivité ont pour conséquence un drainage net, bien que réduit, sur les effectifs sauvages. Un @levage en ranch en plein développement préléve beaucoup plus d'animaux dans la nature, mais, meme s'il n'est procédé 4 aucune réintroduction, l'une des principales conditions pour l'approbation d'un programme d'élevage en ranch au titre de la résolution Conf. 3.15 est qu'il devrait, en contrepartie, profiter Aa la population sauvage, cela ne concernant toutefois que les espéces inscrites 4 1'Annexe I. Protection de l'habitat et des espéces Dans le passé, les crocodiliens @étaient persécutés en tant que vermine et leur habitat marécageux est souvent détruit afin d'ouvrir la voie a une utilisation des sols "plus productive". La capacité des crocodiliens, qui a @té démontrée, de créer un revenu peut aider a la promotion de la conservation de populations sauvages saines. Ceci s'applique en particulier 4 1'élevage en ranch, pour lequel l'ensemble de l'opération dépend du maintien d'un stock reproducteur sauvage; mais, dans une moindre mesure, les fermes pratiquant la reproduction artificielle peuvent encourager la conservation d'effectifs a l'état sauvage aux fins d'améliorations génétiques périodiques. Le maintien d'une population sauvage de crocodiliens est conditionné par la préservation de leur habitat, lequel est favorable a d'autres organismes du meme milieu. Ainsi,. laberaiit financier de l'exploitation des crocodiliens réduit aussi la pression économique qui s'exerce en faveur de l'asséchement des zones humides. Protection culturelle Les techniques d'@élevage en ranch des crocodiliens peuvent étre adaptées aux conditions d'une technologie villageoise permettant leur intégration dans la culture et l'économie des communautés rurales. Les programmes d'@levage en ranch de Papouasie-Nouvelle-Guinée et d'Australie septentrionale ont pour objectif déclaré de fournir des 20 Introduction emplois aux indigénes. D'autres programmes visant A la réalisation d'un revenu entrainent fréquemment des effets technologiques largement plus importants et provoquent une dislocation sur le plan social. Mélange génétique et risque de maladie Les autres inconvénients potentiels comprennent 1'introduction accidentelle d'espéces non indigénes ou de races génétiquement distinctes parmi la population sauvage, parce que des animaux se sont @échappés de la ferme, ainsi que la dissémination de maladies. PERSPECTIVES D'AVENIR Dans la plupart des pays qui aarbritent des @élevages de crocodiliens, il apparait qu'ils augmentent en nombre et en nombre d'animaux, et que la production de peaux s'accroit. Les problémes techniques posés par l'élevage ont &té surmontés, dans une large Mesure, mais quant 4 savoir si cette croissance se poursuivra ou si cette industrie disparaitra, cela dépendra de sa rentabilité A long terme. Le rapport entre le nombre d'animaux prélevés 4 l'état sauvage ("@élevage en ranch") et le nombre d'animaux reproduits en captiviteé constitue un facteur important du point de vue de la conservation. Le nombre total d'animaux reproduits dans des fermes semble s'accroitre et pourrait représenter quelques 40% du nombre total d'animaux s'ajoutant chaque année au cheptel de ces fermes. A premiére vue, cela parait encourageant, mais mérite un examen plus approfondi. La reproduction en captivité a joué un role important pour la conservation de plusieurs espéces de crocodiliens sérieusement réduites en nombre, mais il s'agissait le plus souvent d'opérations non commerciales. L'élevage en captivité Aa des fins commerciales, ainsi qu'on l'a vu plus haut, fait moins en faveur de la conservation et ne devrait pas é@tre considéré, comme il l'est souvent, comme une alternative a la conservation des habitats. L'@levage en ranch, par contre, peut étre beaucoup plus favorable, car il requiert le maintien d'une population sauvage saine et de Il'habitat qui l'abrite (123). Dans le fond, il différe peu d'une exploitation controlée des grands animaux pour leurs peaux; aux Etats-Unis d'Amérique et en Papouasie-Nouvelle-Guinée, les deux types d'exploitation sont conduits cote a cote. L'élevage en ranch présente certains avantages sur la récolte directe car il parait plus facile de le régulariser, en particulier si, comme au Zimbabwe, aux Etats-Unis d'Amérique et en Australie, la récolte des oeufs est entiérement effectuée par le personnel gouvernemental ou sous son étroit controle. Le maintien d'un cheptel @levé en ranch séparé donnerait aussi une assurance, jusqu'a un certain point, au cas ou un désastre se produirait dans le milieu naturel ou si le contréle effectif de la récolte était rompu en raison, par exemple, d'une instabilité politique. C'est pourquoi, la cause de la conservation des crocodiliens pourrait é@tre mieux servie par la mise en place de plans efficaces de gestion des populations sauvages, lesquels comprendraient l'élevage en ranch, la reécolte directe ou une combinaison des deux, que par un arrét total de l'exploitation a4 l'état sauvage et le développement de Introduction l'élevage en captivité. Le succés de tout plan de gestion de ce type dépend entiérement d'une recherche de base minutieuse permettant de déterminer les niveaux des populations existantes et de l'aptitude a conduire l'exploitation de fagon contrdlée. Le niveau é@levé du commerce illicite de produits de crocodiliens (94) donne a penser que le degré actuel de contréle est loin d'étre adéquat dans de nombreuses parties du globe. REMERCIEMENTS. La realisation de cette enquéte aurait été totalement impossible sans l'aide et la coopération accordées par les tres nombreux correspondants qui ont répondu a nos lettres et rempli les questionnaires. Leur aide a été mentionnée chaque fois que possible dans les références, mais les auteurs souhaitent leur exprimer leur gratitude ici-méme. Les fonds nécessaires 4 la réalisation de cette enquéte ont été généreusement fournis par l1'International Fur Trade Federation et par 1'UICN. 22 INTRODUCCION Los cocodrilos se explotan en forma intensiva para la comercializaciédn de sus pieles las cuales alcanzan precios muy elevados. Hasta hace poco tiempo, la demanda de pieles se basaba exclusivamente en la caza de las poblaciones silvestres, pero en los Gltimos afios se ha notado un gran incremento de criaderos de cocodrilos. Los primeros de ellos, denominados "granjas", estaban destinados, sin ningin lugar a dudas, al piblico en general, mas bien en el sentido de zoolégicos, y muchos de ellos aun conservan ese caracter. Sin embargo, la cria para la produccién comercial de pieles se practica cada vez mas. Algunas granjas venden también carne de cocodrilo y, en Taiwan, este fin provee algunas veces la fuente principal de ingresos. La raz6n de este aumento de popularidad de la cria de cocodrilos es dificil de evaluar, pero tiene que ver ciertamente con la reducci6én registrada en el aprovisionamiento de pieles silvestres. Este aumento se debe en parte, a la declinaciédn de las poblaciones silvestres debido a la caza excesiva, a la persecucién y a la destrucci6én del habitat, pero el control relativo a la aplicacién de las leyes podria tener una importancia aun mayor. La principal de ellas es la Convenci6n sobre el Comercio Internacional de Especies Amenazadas de Fauna y Flora Silvestres (CITES). La mayoria de los cocodrilos estdn incluidos en el Apéndice I de la Convencién (ver Cuadro I), lo que Significa que todas las transacciones comerciales entre los paises Partes estan prohibidas a menos que los especimenes provengan de poblaciones criadas en cautividad. Desde la entrada en vigor de la Convenci6n, en 1975, la eficacia de los controles comerciales ha aumentado, debido a que un mayor naimero de paises son ahora Partes de la Convenci6n y también a que se ha registrado una mejora en los procedimientos de aplicacién. La demanda de pieles "clAsicas" de cocodrilos mas solicitadas, especialmente las de Crocodylus niloticus y Crocodylus porosus, se mantiene a un nivel alto y, como las otras fuentes de pieles se han cerrado, las operaciones de cria en granjas parecen haber prosperado. Esta Guia de criaderos de cocodrilos fue elaborada, en parte, para facilitar la aplicaci6n de los controles CITES, identificando los criaderos y las denominadas "granjas" que no realizan la reproduccién de cocodrilos, y también para determinar la importancia del criadero, con miras a evaluar sus efectos sobre la conservacidn de los cocodrilos. También trata de establecer una lista de todas las granjas comerciales de cocodrilos y ofrece informaciones detalladas de sus stocks, produccién, logros en materia de reproducci6n asi como sobre las técnicas de cria. La encuesta fue elaborada, en primer lugar, con el objeto de localizar los criaderos comerciales, pero también se han incluido a los grandes centros de reproducciédn de cocodrilos orientados hacia la conservacién, en parte porque algunos de ellos podrian transformarse en futuros criaderos comerciales. Por esa misma razon, se tuvieron también en cuenta los proyectos de criaderos comerciales. En la presente Guia, la palabra "granja" se utiliza para designar cualquier criadero en cautividad, en el sentido mas amplio del término (es decir también la detencién durante por lo menos un 23 Introduccion cierto periodo); comprende entonces a los criaderos cuyo plantel fue obtenido de la naturaleza y a los criaderos que practican la reproducci6n en cautividad. Los zoolégicos del mundo entero poseen cocodrilos que se reproducen, pero no se los ha tomado en consideraci6n. Cabe sefialar que la inclusién de un criadero en la presente Guia no implica de ninguna forma que la granja satisfaga las exigencias de CITES relativas a su reconocimiento como cria en cautividad. Esa funci6n la realiza la Secretaria CITES por medio del Registro de establecimientos que practican la cria en cautividad, segin la explicaci6én ofrecida en la seccién siguiente. Controles CITES del comercio Debido a que los controles CITES son muy importantes para comprender la cria de cocodrilos y a la confusién que reina al respecto de su interpretaci6én, la siguiente secciédn resume las exigencias relativas al comercio de productos de cocodrilos. Todo el comercio concerniente a los paises Partes de la Convenci6én se halla sometido a las disposiciones de ella, siempre que no se trate de especimenes adquiridos antes de que la Convencién haya entrado en vigor o a menos de que el pais haya formulado una reserva con respecto a la especie en cuesti6én, en ese caso, ese pais eS considerado como un Estado no Parte. Los paises que formularon reservas con respecto a los cocodrilos se mencionan en el Cuadro I. Otros paises, como por ejemplo Italia y Francia, habian formulado reservas, pero actualmente las han retirado. Todos los cocodrilos gozan de protecci6dn de acuerdo con la Convenci6n ya que se hallan incluidos en el Apéndice I o en el Apéndice II. En el Apéndice I se hallan incluidos los taxa amenazados de extinci6én que estan o podrian estar amenazados por el comercio. En la practica, el comercio internacional de esas especies se halla prohibido, siempre que la Parte exportadora no emita un permiso de exportaci6én. Esto solamente puede hacerse si el comercio no perjudica a la supervivencia de la poblacién silvestre y si la Parte importadora emiti6 un permiso declarando que los animales o los productos no seran utilizados con fines primordialmente comerciales. Existen algunas excepciones, la principal concierne al comercio de animales que provienen de poblaciones criadas en cautividad de acuerdo con las condiciones indicadas mas abajo. Esos animales son tratados como si estuvieran incluidos en el Apéndice II. En el Apéndice II estan incluidos los taxa cuyo comercio debe estar sometido a una reglamentaci6n estricta con el objetivo de evitar que ellos, o las especies similares incluidas en ese mismo Apéndice, no esten amenazadas de extinci6édn en el futuro. Por lo tanto, el comercio esta solamente permitido cuando el pais de exportaci6én emite un permiso de exportaci6n que indica que el comercio no perjudica a la supervivencia de la poblacién silvestre. 24 Introduccion Los paises Partes de la Convenci6én deben tratar a los Estados no Partes casi como si estos fueran Partes. En otros términos, si un comerciante de un Estado Parte desea importar una especie del Apéndice II de un Estado no Parte debe obtener un documento equivalente al permiso de exportaci6n CITES. Cria en cautividad En la reunién CITES de San José, Costa Rica, 1979, se definieron las condiciones por las cuales los especimenes de una especie incluida en el Apéndice I pueden ser considerados como "criados en cautividad", las cuales se especifican en la resoluci6én CITES Conf. 2.12. Resumiendo, esas condiciones son las siguientes: ala Los animales pueden solamente ser comercializados como especimenes criados en cautividad si nacieron en cautividad y si descienden de padres que se reprodujeron en cautividad (o en un "medio controlado"). Ze El stock parental debe ser (i) obtenido sin perjudicar la supervivencia de la especie al estado silvestre; (ii) Mantenido sin incrementos provenientes de las poblaciones silvestres, excepto aquellos aportes ocasionales con fines de mejoramiento genético; (iii) administrados de forma que se pueda ofrecer la prueba de que ese stock permite producir en forma segura una descendencia de segunda generaci6én. Conviene sefalar que las granjas no necesitan producir descendencia de segunda generaci6dn siempre que las técnicas que se aplican hayan ofrecido la prueba, en otro sitio, de que se puede producir ese tipo de descendencia. Registro de establecimientos que realizan cria en cautividad Algunos comerciantes poco escrupulosos pueden abusar de esas reglamentaciones simplemente obteniendo animales del medio silvestre y vendiéndolos pretendiendo de que fueron criados en cautividad. Por lo tanto es necesario establecer un registro efectivo de los criaderos reconocidos que producen especimenes de especies del Apéndice I criados en cautividad. Esta necesidad fue reconocida en la reuni6én de CITES de Gaborone, Botswana, en 1983, donde se adopt6 una resolucién (Conf. 4.15) que recomienda que las transacciones comerciales relativas a especies del Apéndice I criadas en cautividad esten solamente autorizadas para los establecimientos registrados por la Secretaria CITES. El registro se hace efectivo cuando la Autoridad Administrativa CITES del pais de origen comunic6 a la Secretaria informaci6én detallada con respecto a la granja (informacién que se especifica en la notificaci6n a las Partes No. 223 del 13 de octubre de 1983) y cuando confirm6 que se _ respetan las condiciones especificadas en la resolucién Conf. 2.12. Al momento de la impresién de esta Guia, sdlo se habian registrado cuatro establecimientos que crian cocodrilos incluidos en el Apéndice I, uno en Madagascar, uno en Queensland, Australia, uno en Tailandia y el f<imo en Transvaal, Sudaéfrica. Introduccion Cria en granjas Se ha reconocido que algunas poblaciones de especies incluidas en el Apéndice I se han reconstituido debido a las medidas de conservaci6én, por lo que ya no se encuentran mas amenazadas. Estas poblaciones pueden soportar un nivel de explotacién controlado y pueden por lo tanto beneficiarse de ello. Por tal motivo, se recomend6 un procedimiento en la reunién de CITES de Nueva Delhi, India, 1981, por el cual algunas poblaciones de especies incluidas en el Apéndice I que podian gozar de los efectos de la cria en granjas podian ser transferidas al Apéndice II (Conf. 3.15). La cria en granjas se define como la cria en un medio ambiente controlado, de especimenes obtenidos de la naturaleza, con miras a su comercializaci6én. Para que sea reconocido, el criadero debe favorecer a la poblacién silvestre y sus productos deben ser marcados para que puedan ser diferenciados de los otros productos provenientes de otras poblaciones de la misma especie incluidas en el Apéndice I. Conviene sefmalar que, dado que existe un intercambio potencial continuo entre las poblaciones criadas en granjas y aquellas que viven al estado silvestre en el pais, se las trata en forma similar desde el punto de vista de la Convenci6én y ambas pueden ser objeto de comercio. Corresponde a la Autoridad Administrativa local elaborar las reglamentaciones que permitan diferenciar los productos provenientes de animales criados en granjas de aquellos provenientes del medio natural. Sin embargo, en 1985 se adopt6 una resoluci6én (Conf. 5.16) que solicita que todas las condiciones establecidas en la propuesta original de cria en granjas sean respetadas por todas las Partes que realizan comercio de especimenes de la poblacién criada en granjas. De esta forma y dado que la propuesta australiana relativa a la cria en granjas de C. porosus estipula la prohibici6n de vender pieles de animales que no se encuentran en una granja desde hace por lo menos un afio, las otras Partes no deberian autorizar la importaciones de dichas pieles. La poblaci6én de C. niloticus de Zimbabwe fue transferida al Apéndice II en 1983 sobre la base de un programa de cria en granjas y la poblaci6én australiana de C. porosus fue transferida en 1985 sobre la base de un programa del mismo tipo. db En 1985, en Buenos Aires se adopt6 otra resoluci6én con respecto al comercio de especimenes criados en granjas. La misma recomienda, entre otras cosas, que los productos provenientes de cria en granjas no se exporten hacia Estados no Partes ni hacia Partes que hayan formulado reservas con respecto a las especies que son objeto de una cria en granjas, y que no se acepten las importaciones de productos provenientes de esos Estados. Algunas connotaciones de lo que precede hacen que Australia no deberia autorizar las exportaciones de pieles de C. porosus criados en granjas si su destino es Singapur, que no es Parte, o Jap6n que ha formulado una reserva con respecto a esa especie. La reuni6én de Buenos Aires, Argentina, fue notable en el sentido de que se modificé el procedimiento para transferir del Apéndice I al Apéndice II, de las especies que fueron incluidas en el Apéndice I 26 Introduccion antes de la adopcién de los criterios cientificos a tal efecto y que evidentemente pueden soportar un cierto nivel de explotacién. El nuevo procedimiento preve el establecimiento de un cupo para cada pais que desea comercializar esas especies, dentro del marco de un plan de Manejo reconocido. Por medio de este procedimiento, la poblaci6n de C. porosus de Indonesia fue transferida al Apéndice II con un cupo de 2000 pieles. Las poblaciones de C. niloticus de los nueve paises africanos mencionados en el Cuadro 2 también fueron transferidas al Apéndice II con los cupos indicados. Los programas de cria en granjasS poseen numerosas ventajas con respecto a la explotaci6n directa, ya que permiten capturas mas importantes de una determinada poblaci6n silvestre, producen pieles de mejor calidad y, con ellos, es mas facil asegurarse que se aplica la reglamentacién. Sin embargo, es mas dificil aplicarlos y necesitan capitales mas importantes. En consecuencia parece paradojico que las decisiones tomadas en Buenos Aires hayan eliminado ciertas ventajas econémicas de los programas de cria en granjas de especies incluidas en el Apéndice I - sus mercados potenciales son actualmente menores - mientras que el sistema de cupos para la transferencia de poblaciones al Apéndice II goza de una mayor fiexibilidad en lo que respecta a la disponibilidad de los productos en el mercado. METODOS La encuesta fue efectuada en 1983 y 1984. La Secretaria CITES envi6éd una notificacién a las Partes de la Convencién con respecto a la necesidad de registrar todos los establecimientos que realizan la cria en cautividad con fines comerciales de especies incluidas en el Apéndice I. La Unidad de Vigilancia continua del Comercio de Fauna y Flora Silvestre también tom6 contacto con las autoridades competentes en materia de manejo de fauna silvestre de los gobiernos de los Estados no Partes. También se establecieron contactos con los miembros del Grupo de Especialistas de Cocodrilos de la CSE, con las asociaciones de criadores y con otras personalidades que conocen el tema. Siempre que fue posible, se enviaron cuestionarios a las granjas mismas con el objeto de obtener informaciédn detallada sobre sus stocks, la reproduccién, la captura al estado silvestre, su producci6én comercial y sus técnicas de cria. Los resultados presentados en este documento provienen de las respuestas a eSas encuestas, y también de materiales publicados y no publicados y de informes de prensa. En la Guia, los resultados se presentan por pais. RESULTADOS Y DISCUSION Los paises y las especies mencionadas en el texto se enumeran en el Cuadro 3, el cual indica también donde se encuentran los establecimientos. Las especies m&s intensivamente criadas en granjas son C. niloticus y C. porosus: estoes, en parte, el reflejo de su amplia distribucién, pero ademas el valor de sus pieles, ya que ambas son muy estimadas por la industria del cuero. 27 Introduccion Los efectivos de las principales especies que se encuentran en las granjas de tipo comercial se presentan en el Cuadro 4, donde se puede ver que el Alligator mississippiensis es probablemente la especie mas abundante, aunque C. niloticus y C. porosus alcanzan efectivos del mismo orden de tamanho, los datos sobre esas especies son sin embargo bastante incompletos. El n&mero total de granjas se indica en el Cuadro 5, junto a otras informaciones relativas a su produccién. Se cree que existen otras formas, por ejemplo en Singapur y en Malasia, pero no se ha podido obtener ninguna otra informacién. De las 152 granjas conocidas en 1985, menos de 20 existian en 1974 y todo indica que esa raépida expansién continua. El plantel de cocodrilos de 161.603 evidentemente también aumenta. El aumento del plantel debido a la captura de animales silvestres y a la reproducci6dn en cautividad alcanza aproximadamente 72.000 cabezas por ano. Como es de esperar con una industria tan jéven, la producci6én de pieles es relativamente baja, los criadores tratan aparentemente de constituir sus planteles. Antes de 1979, mientras las granjas de Papua Nueva Guinea comenzaban a producir, las Gnicas cantidades apreciables de pieles vendidas por las granjas provenian de Zimbabwe. Esta encuesta demostr6 que por lo menos 14.769 pieles de granja habian entrado en el mercado en 1983/84. Si se considera la hipétesis de que la mayor parte del aumento del plantel de granjas esta destinado a la matanza en un plazo de cuatro afios, la produccién podrian alcanzar 60.000 pieles hacia 1989, aunque es poco probable que el aumento sea tan rapido. Finanzas Aunque los controles ejercidos, sobre la caza de cocodrilos en virtud de la aplicaci6én de las leyes juega sin ninguna duda un papel muy importante creando condiciones favorables al establecimiento de granjas, el factor que, en fin de cuentas, determinara su futuro es el éxito financiero. Las compafiias comerciales, se lo puede comprender, no estan muy dispuestas a mostrar sus cuentas para permitir un estudio y, de esta forma, es dificil evaluar su rentabilidad. Ademas, la mayoria de las granjas se encuentran actualmente en una etapa de desarrollo y por lo tanto se puede esperar que el balance sea negativo hasta que no se alcance la plena producci6n. Para comenzar, parece entonces razonable examinar primeramente las granjas mas antiguas. Una de las granjas mas antiguas del mundo es la de Samutprakan en Tailandia. En 1983, se decia de que disponia de un plantel de 30.000 cocodrilos, pero solamente produjo 200 pieles. Financieramente es evidente que ella no podia solamente sobrevivir del producto de la venta de pieles, el establecimiento obtenia la mayor parte de sus ingresos de los turistas y pretendia autofinanciarse de esa forma. También las granjas de los Estados Unidos, presentaban una mala relaci6n plantel/producci6én, aunque ellas venden también carne y pieles, lo que deberia contribuir a aumentar sus beneficios. Algunas granjas crean otras fuentes de ingresos vendiendo animales vivos a 28 Introduccion otras granjas y algunas cuentan también con los ingresos producidos por el turismo. Un andlisis reciente (96) indica que el valor de un animal en el matadero es de US$200-300, mientras que los gastos de producci6én, que comprenden la alimentacién, el trabajo y la adquisici6n de recién nacidos, alcanzan US$85-100. Esto ofrece un beneficio estimado de US$80-192 por animal tomando en cuenta una mortalidad del 10%. Ante &sto el costo del capital invertido, estimado a ser US$50.000-200.000 (40), cuyo interés tendria wun valor de US$5000-20.000 al afio por cuatro afios antes de que ninguna produccién tomara lugar. Con las estimacidnes mAs pesimistas, un granjero necesitaria pues vender 345 animales solamente para pagar el interés autres de recuperar su inversi6én inicial. El aumento del nimero de granjas en los Estados Unidos de América fue lento hasta 1982 y se creyd que la causa principal en favor de los criaderos residia en el interés que existia con respecto a los aligatores, el cual podia solamente provenir de personas ricas y no interesadas en la obtenci6n de beneficios raépidos (123). Sin embargo, el aumento acelerado del niémero de granjas durante estos dos iéltimos afios, especialmente en Florida, hace pensar que se pueden esperar ganancias substanciales, si es que ya no se han obtenido. Esto puede estar ligado al aumento del nimero de recién nacidos, eclosionados de huevos recogidos en la naturaleza, disponibles y provenientes del Louisiana Rockefeller Refuge y especialmente del programa especial de Florida. Las granjas de Zimbabwe gozan también de un programa oficial de recoleccién de huevos y Magnusson (123) atribuye su aparente rentabilidad al hecho de que la mano de obra es barata y a que el aprovisionamiento en alimentos ricos en proteinas para los cocodrilos es poco costoso y abundante, ambos elementos podrian, segin ese autor, disminuir en el futuro. Varias de esas granjas también obtienen una parte importante de sus ingresos del turismo y de la venta de recuerdos para el turista (179). La cria en granjas de cocodrilos en Papua Nueva Guinea constituye un modelo que otros paises tratan de imitar y que contribuye al conjunto de la produccién mundial de pieles provenientes de granjas (Cuadro 5). Aunque numerosas pequefas granjasS inicialmente instaladas ya han desaparecido, las que se mantienen son aparentemente capaces de realizar un beneficio, casi exclusivamente sobre la venta de pieles (85). Un andlisis de la cria en granjas en Australia; que concierne también C. porosus, estimaba los gastos totales de adquisicién y de ceria por animal a A$35-55 para un tamafio de matadero de 5-6 piés (1,52-1,83 m). A este nivel, el valor de las pieles estaba evaluado a A$150-180 (192). Es evidente que la cria en cautividad de cocodrilos requiere mas dinero, en lo que respecta a los gastos corrientes y de conservacién del stock reproductor, que el capital inicial necesario al establecimiento de las instalaciones de reproducci6n, que la cria a partir de huevos o de juveniles obtenidos al estado silvestre. Magnusson (123) ha indicado que la mayoria de les establecimientos que logran un éxito financiero son aquellos cuyos stocks de crianza 29 Introduccion dependen en su mayor parte de las poblaciones silvestres de cocodrilos. Por lo tanto, es un poco soprendente que las granjas de Zimbabwe y de los Estados Unidos de América realizan cada vez mas crias a partir de sus propios planteles y la reproduccién es tratada cada vez mas seriamente en Papua Nueva Guinea. Esto puede explicarse por el hecho de que numerosos establecimientos dependen, por lo menos en parte, de los ingresos provenientes del turismo. Existe una verdadera semejanza entre lo requerido para satisfacer a los turistas y lo requerido para practicar la reproducci6n, es decir animales adultos y de gran tamafo y piletones seminaturales; y los importantes capitales invertidos en las nuevas granjas orientadas hacia el turismo demuestran que los financistas esperan, finalmente, ganar dinero al hacerse cargo de ese tipo de riesgo. La cria de cocodrilos y sus efectos sobre la conservaci6én El hecho de saber si la cria de cocodrilos es deseable desde el punto de vista de la conservaci6n origin6 una animada controversia. los argumentos en favor y en contra de la cria se resumen a continuacién: Desviaci6n del comercio Dado que existe un mercado para los productos de cocodrilos que de otra forma seria aprovisionado por la caza de las poblaciones silvestres, disponer de esos mismos productos a partir de animales criados en granjas podria satisfacer una parte de la demanda y reducir la necesidad de caza. Puede discutirse la cuesti6n de saber si eso ocurre en la practica o si los productos de las granjas aumentan simplemente la amplitud del mercado. Normalmente, el efecto principal deberia ser de orden econémico; disminuyendo el precio de las pieles o reduciendo a niveles inaceptables el margen de ganancia ofrecido por la caza. Este efecto es particularmente notable cuando la operacién de caza es manejada pobremente y la poblacién silvestre se aproxima hacia la “extincci6n comercial". Las pieles de criadero tienden a ser de mejores y de calidad m&4s uniforme que las pieles silvestres, lo que le ofrece una ventaja competitiva en el mercado, aunque puedan, por eso mismo, venderse a un precio mas elevado. Por otro lado se ha emitido la hipétesis de que si el comercio ilegal se pudo reducir con éxito gracias a medidas de control, la demanda del piblico también disminuira. Cualquier nueva estimulaci6én del mercado debido a la introduccién de productos de granja aumentara la demanda aun mas y renovara quizas la presién de caza sobre las poblaciones silvestres. Este efecto deberia también ser mas importante en los sitios donde el comercio ha practicamente cesado, en general para las especies incluidas en el Apéndice I. Ambos argumentos estan influenciados por la importancia relativa de los aprovisionamientos en pieles provenientes de granjas y del medio silvestre. Recientemente el comercio internacional de pieles de cocodrilos ha sido estudiado por Hemley y Caldwell (94) que encontraron que el comercio de las principales especies, excepto Caiman crocodilus, mencionados en los informes CITES alcanzaron por lo menos 82.000 animales por aflo, aunque sefalan que se trata ciertamente 30 Introduccion de una subestimaci6én. La producci6én en granjas de 12.000 pieles ya constituye una parte importante de ese mercado y esta importaci6én ird en aumento. Sin embargo, la mayor parte del comercio concierne sin ninguna duda a C. crocodilus, ya que los informes CITES indican 700.000 pieles por ano y que el niémero real es probablemente superior al millén (94). Taiwan es el finico territorio en el cual esta especie es criada en gran cantidad, principalmente porque el bajo valor comercial de las pieles significa que el criadero es econdémicamente rentable solamente si se pueden comercializar otros productos. En consecuencia, eS poco probable que la cria produzca alguna vez una parte importante del mercado mundial de pieles de C. crocodilus, o de pieles de cocodrilos en su conjunto, a menos que el comercio de pieles de caimanes silvestres disminuya en forma drastica. Control del comercio El control del comercio ilegal de productos de especies amenazadas de extinci6n se complica por la introduccién en el mercado de productos de granja adquiridos legalmente. Este problema fue tratado por las resoluciones CITES sobre la cria en cautividad (Conf. 2.12) y sobre la cria en granjas (Conf. 3.15) que recomiendan el marcado apropiado de los productos, con el objeto de que puedan ser distinguidos de los productos provenientes de animales obtenidos de la naturaleza. Sin embargo, siempre se teme que algunos comerciantes sin escrfpulos utilicen a las granjas para disponer de pieles silvestres adquiridas en forma ilegal, ya sea en forma directa a partir de la granja, © por medio de reexportaciones a partir de otros paises. Varios paises que poseen criaderos de cocodrilos elaboraron procedimientos en materia de permisos y de inspecci6én cuyo objetivo es prevenir ese tipo de actividad, pero se han sefialado operaciones de "blanqueo" de pieles ilegales realizadas por algunas granjas. La presente Guia puede ser itil para evitar ese problema ya que se trata de ofrecer un nivel real de los stocks actuales y de informar sobre los éxitos efectivos obtenidos con respecto a la reproducci6n. Cualquier produccién de pieles provenientes de granjas que sobrepase la capacidad de producci6én reconocida o que provengan de paises que no disponen de granjas deberian ser investigados. Efecto sobre las poblaciones silvestres Si los efectivos de una especie disminuyen o si se encuentran amenazados de extinciédn al estado silvestre, la cria en cautividad puede tener un efecto de protecci6n para una parte importante de la poblacién. Si la reproduccién puede también asegurarse, la poblaci6én puede aumentar hasta un punto en que puede ser posible la reintroduccién de animales reproducidos en cautividad en la naturaleza. Varios establecimientos que practican la reproducci6én de cocodrilos han logrado sin lugar a dudas alcanzar ese nivel, especialmente con las especies Crocodylus moreletii, Crocodylus intermedius y Gavialis gangeticus, pero siempre se trat6 de establecimientos orientados hacia la conservaci6én y sin intenciones comerciales. El Gnico establecimiento comercial que utiliza actualmente una especie seriamente amenazada de extincién, Crocodylus siamensis, es la granja de Samutprakan en Tailandia. La granja de los 31 Introduccion pantanos de Zapata en Cuba practica también la reproduccién de Crocodylus rhombifer y Crocodylus acutus, pero no se conoce el nivel en que esta granja esta concernida por el comercio. Sin embargo, no se ha podido determinar si es de desear la reintroduccién de animales provenientes de granjas, a causa de su alteraci6én genética debido a la selecci6n artificial o a la hibridaci6én. La granja de Samutprakan y la de los pantanos’ de Zapata ya poseen importantes planteles substanciales de animales hibridos. Muy raramente la cria en cautividad es totalmente independiente de la poblaci6n silvestre y a menudo es necesario la captura de animales silvestres, si no es para criarlos directamente por lo menos para adquirir un stock reproductor. De esta forma, mismo los establecimientos que aseguran la reproduccién en cautividad tienen en consecuencia un drenado neto, aunque reducido, de los efectivos silvestres. Una cria en granjas en pleno desarrollo captura muchos mas animales de la naturaleza, pero, aunque no- realice ninguna reintroducci6én, una de las condiciones principales para la aprobaci6én de un programa de cria en granjas de acuerdo con la resoluci6én Conf. 3.15 es que deberia, como contrapartida, beneficiar a la -poblacién silvestre, esto concierne solamente a las especies incluidas en el Apéndice I. i Protecci6n del habitat y de las especies En el pasado, los cocodrilos eran perseguidos como animales perjudiciales y a menudo sus habitats pantanosos se destruyen con el objeto de abrir una via a una utilizacién del suelo "mas productiva". La capacidad de los cocodrilos de producir fuentes de ingresos, que ya se ha demostrado, puede ayudar a promover la conservaci6n de poblaciones silvestres sanas. Esto se aplica en particular a la cria en granjas, para la cual el conjunto de la operacién depende del mantenimiento de un stock reproductor silvestre pero, en mucha menor medida, las granjas que practican la reproduccién artificial pueden alentar la conservacién de efectivos al estado silvestre con el objeto de periéddicas mejoras genéticas. El mantenimiento de una poblacién silvestre de cocodrilos se halla condicionado por la preservaci6én de su habitat, el cual es favorable a los otros organismos que viven en el mismo medio. En consecuencia, la atracci6n financiera de la explotaci6én de cocodrilos reduce también la presién econémica que se ejerce en favor del secado de las zonas himedas. Protecci6n cultural Las técnicas de cria de cocodrilos en granjas pueden ser adaptadas a las condiciones de una tecnologia de pueblo para permitir la integraci6én de la cultura y de la economia de las comunidades rurales. Los programas de cria en granja de Papua Nueva Guinea y de Australia septentrional declaran como objetivo el ofrecimiento de empleos a los indigenas. Frecuentemente, otros programas que tienden a obtener un ingreso provocan problemas a nivel social. 32 Introduccion Mezcla genética y riesgos de enfermedades Los otros inconvenientes potenciales comprenden la introducci6én accidental de especies no indigenas o de razas genéticamente diferentes en la poblacién silvestre, porque algunos animales se escaparon de la granja, asi como la diseminaciédn de enfermedades, propias a las granjas, a las poblaciones silvestres. PERSPECTIVAS FUTURAS En la mayoria de los paises que realizan operaciones de cria en granjas de cocodrilos parece que estos establecimientos aumentan en naimero asi como en cantidad de animales y que la producci6én de pieles aumenta. Los problemas técnicos originados de la cria han sido, en gran medida, solucionados, pero saber si este crecimiento continuara o si esta industria desaparecera depende de su rentabilidad a largo plazo. El niémero de animales silvestres capturados en la naturaleza ("cria en granjas") y el nimero de animales reproducidos en cautividad constituye un factor importante desde el punto de vista de la conservaci6n. El nimero total de animales reproducidos en las granjas parece aumentar y podria representar el 40% del nimero total de animales que se agregan anualmente al plantel de esas granjas. A primera vista, esto parece alentador, pero merece un examen mas profundo. La reproduccién en cautividad tuvo un importante papel en la conservaci6n de varias especies de cocodrilos seriamente reducidas en nimero, pero se trataba a menudo de operaciones no comerciales. La ceria en cautividad con fines comerciales, tal como se lo explica mas arriba, no es tan beneficiosa para la conservaci6n, y por lo tanto no deberia ser vista, como frequentemente es, como una alternativa a la conservaci6n del habitat. En cambio, la cria en granjas, puede ser mucho mas beneficiosa ya que requiere el mantenimiento de una poblaci6én silvestre sana asi como del habitat que la alberga (123) En esencia, difiere poco de una explotaci6én controlada de pieles de grandes animales; en los Estados Unidos de América y en Papua Nueva Guinea, los dos tipos de explotaci6én se llevan paralelamente. La cria en granjas presenta ciertas ventajas sobre la recoleccién directa ya que parece mas fAcil reglamentar, especialmente si, como en Zimbabwe, Estados Unidos de América y en Australia, la recoleccién de huevos es totalmente efectuada por personal del gobierno o bajo su estricto control. El mantenimiento por separado de un plantel en granjas ofrece también cierta garantia, en el caso de que hubiera un desastre en el medio natural o en el caso de que se interrumpiera el control efectivo de la recoleccién debido por ejemplo a la inestabilidad politica. Por tal motivo, la causa de la conservaciOn de cocodrilos estaria mejor servida si se estableciera un plan de manejo eficaz de las poblaciones silvestres, el cual comprenderia la cria en granjas, la recoleccién directa o una combinaci6n de ambas, en lugar del paro total de la explotacién al estado silvestre y el desarrollo de la cria en cautividad. El éxito de cualquier plan de manejo de ese tipo depende totalmente de una investigaci6n de base minuciosa que permita S15) Introduccion determinar los niveles de las poblaciones existentes y de la aptitud para conducir la explotaci6én en forma controlada. El alto nivel del comercio ilegal de productos de cocodrilos (94) hace pensar que el grado actual de control dista mucho de ser el adecuado en numerosas partes del mundo. AGRADECIMIENTOS Los fondos necesarios para la realizaci6n de esta encuesta fueron generosamente ofrecidos por la International Fur Trade Federation y por la UICN. La realizaci6én de esta encuesta no hubiera sido posible sin la ayuda y colaboraci6n acordada por las numerosas personas que respondieron a nuestras cartas y cuestionarios. Se hace referencia a esa ayuda cada vez que es posible y los autores desean expresar aqui mismo su inmensa gratitud. 34 Table 1 Species of crocodilian mentioned in the text, giving the English names and status in the CITES Appendices. = SSS eee eee Scientific name English names CITES Countries Appendix which hold reservations (July 1985) ———— eee Alligator mississippiensis Alligator sinensis Caiman crocodilus apaporiensis Caiman crocodilus crocodilus Caiman crocodilus fuscus Caiman crocodilus yacare Caiman latirostris Melanosuchus niger Paleosuchus palpebrosus Paleosuchus trigonatus Crocodylus acutus Crocodylus cataphractus Crocodylus intermedius Crocodylus johnsoni Crocodylus moreletii Crocodylus niloticus C. novaeguineae novaeguineae C. novaeguineae mindorensis (=Crocodylus mindorensis) Crocodylus palustris Crocodylus porosus Crocodylus rhombifer Crocodylus siamensis Osteolaemus tetraspis Tomistoma schlegelii Gavialis gangeticus American alligator II Chinese alligator I Rio Apaporis caiman I Spectacled caiman II Brown caiman LE Yacare caiman II Broad-nosed caiman I Black caiman I Dwarf caiman, Cuvier's II smooth-fronted caiman Schneider's smooth-fronted II caiman American crocodile I African sharp-nosed it Austria, crocodile Zambia Orinoco crocodile I Australian freshwater or II Johntson's crocodile Morelet's crocodile I Nile crocodile I Botswana, Sudan Zambia, Zimbabwe (II in Cameroon*, Congo*, Kenya*, Madagascar”, Malawi*, Mozambique’, Sudan’, Tanzania’, Zambia’, Zimbabwet ) New Guinea crocodile II Freshwater crocodile Mindoro crocodile i Mugger, marsh crocodile, E broad-snouted crocodile Estuarine crocodile, I Austria, Japan, Saltwater crocodile Thailand (II in PNG, Australiat, Indonesia*) Cuban crocodile I Siamese crocodile I W.

Wherever possible details of individual farms have been presented. se ae ries rs ting: POs tnd oginy -* ‘3 ‘= 7 => ea hha) A MNS ys wt a : AUSTRALIA Crocodile harvesting in the past has caused depletion of the crocodile populations in Australia. The saltwater crocodile Crocodylus porosuS was particularly severely affected and the species was protected in 1971. As a result of protection the numbers increased and in 1983 the Australian Council of Nature Conservation Ministers (CONCOM) prepared a proposal for the fourth meeting of the Conference of the Parties to CITES, at Gabarone, Botswana, to transfer the Australian population of C. porosus to Appendix II Supported by a ranching programme. This proposal was withdrawn prior to the meeting in the face of opposition from the IUCN/SSC Crocodile Specialist Group. The proposal was rewritten after the collection of further information on the status of crocodile populations and submitted to the fifth CITES meeting, at Buenos Aires, Argentina, in 1985, where it was approved. The first crocodile farm was established in Queensland in 1973 and achieved captive breeding shortly afterwards. In 1984 it became the second farm in the world to be registered with the CITES Secretariat as a recognised captive-breeding operation. A further three farms were established in the Northern Territory and one in Queensland in the early 1980s. The Conservation Commission of the Northern Territory, which carries out much of the research on crocodile biology, has supervised the wild-capture of the animals held on the three farms in the Territory. It has organised trials to quantify a sustainable level of annual harvest within specified management areas. A number of animals have been removed from areas in which they were considered a potential hazard to the public (51). All stages of the farming process are subject to regulatory control. Licences to farm are only granted to those with suitable experience, and require prior submission of farm design, husbandry, development and financial plans. Licensees are required to submit monthly reports of stock and are subject to random spot checks by the Conservation Commission. Permits are required to slaughter stock, the dates of slaughter being specified, and serially numbered tags are issued for all skins. Tag numbers are specified on permits for all skins exported. The Conservation Commission keeps computer records of all farms, which allows for checking of authorised stocks and skins at all times (192). A trial egg harvest for C. porosus has been proposed which would involve the taking of 4000 eggs a year for three years from the Northern Territory. These eggs will be supplied to the three farms in the Territory. No harvest is planned for Queensland. Hatchlings totalling 5% of the number of eggs collected must be made available for release at one year old should this be required by the Conservation Commission. A trial harvest of up to 200 juvenile C. porosus (0.6-2 m) was planned to assess the effect of this in comparison to egg harvest. Experience with rearing C. johnsoni has shown that 90% survival to Slaughter age is expected. Some problems with feeding in C. porosus have resulted in survival falling to 50%, but the Edward River Farm in Queensland has demonstrated 80% survival with a minor alteration to the diet (192). 51 Australia Both species have bred on farms and it is expected that 100 nests of C. porosus will be laid on farms in 1984/85 (70 in Queensland and 30 in Northern Territory), equivalent to 5200 eggs. Less than 5% of the eggs of later clutches are infertile although the percentage is higher in first clutches (192). All the farms are associated with enterprises which supply food at Minimal cost. In 1984 Government economists re-assessed the long-term financial viability of farms and found them favourable, even given the prevailing depressed skin prices. The financial analysis assumed at least a 5% return of raised juveniles to the wild. A trial harvest of C. porosus eggs in 1983/84 showed that collection by helicopter and incubation costs amounted to A$5 a hatchling, and that the cost of raising each hatchling to a size of 5-6 ft was A$30-40. The skin of an animal of this size was worth A$150-180 in 1984 (192). Whitaker et al. (204) quoted the prices of dried meat and gall bladders in Australia as US$15 kg-l and Us$245 kg-l respectively in 1985. The operations Northern Territory NAME OF OPERATION Crocodile Farm (N.T.) Pty Ltd P.O.Box 4694 Farm Site Darwin, N.T. Director: Mr Michael Hannon. DATE OF ESTABLISHMENT 1981 (51) SPECIES AND NUMBERS The stock of Crocodylus_ johnsoni and Crocodylus porosus held in June 1984 (192) or December 1983 (51) was: Species Hatchlings Juveniles Adults TOTAL C. porosus 331 185 108 624 (192) C. johnsoni 1089 1194 96 2379 (51) * 2368 (192) PRODUCTION AND TRADE The farm has not started production but expects to do so in 1985. Trade is expected to involve the export of raw hides to Asian and European markets (51). SOURCE OF ANIMALS The animals have been obtained as eggs, hatchlings and some adult "problem animals', from the wild under the supervision of the Conservation Commission of the Northern Territory (51). BREEDING It was anticipated that C. porosus would produce up to 30 clutches of eggs on this farm in 1984/85. At a mean clutch size of 52 this would represent up to 1560 eggs (192). 52Z Australia OTHER INFORMATION It was reported in 1983 that this farm was involved with the tourist side of the industry (187). The farm has made a substantial investment in tourist facilities from which some return is being realised (51). NAME OF OPERATION Letaba Crocodile Rearing Station P.O. Box 2351 Darwin N.T. 5794. Operated by: Hilton D. Graham. DATE OF ESTABLISHMENT The operation was established in 1982 (51). In June 1983 the farm was still under construction (88), but was in operation by late 1984 (92))h SPECIES AND NUMBERS The stock of Crocodylus johnsoni and Crocodylus porosus held in June 1984 (192) or December 1983 (51) was: Species Hatchlings Juveniles Adults TOTAL C. porosus 172 49 0 221 (192) C. johnsoni 1820 0 0 1820 (51) 7 1707 (192) PRODUCTION AND TRADE The farm has not started production but expects to do so in 1985. Trade is expected to involve the export of raw hides to Asian and European markets (51). SOURCE OF ANIMALS In June 1983 a small "nucleus" stock of crocodiles for Letaba Crocodile Rearing Station was being held at Janamba Crocodile Farm (88). All of the animals held were obtained as eggs, hatchlings and some adult ‘problem animals', from the wild under the supervision of the Conservation Commission of the Northern Territory (51). NAME OF OPERATION Janamba Crocodile Farm Box 92 Humpty Doo NT 5791. The Director of the farm was Alistair Graham, but recent reports Suggest that he no longer holds this post. DATE OF ESTABLISHMENT November 1982 53 Australia SPECIES AND NUMBERS The stock of Crocodylus johnsoni and Crocodylus porosus held in June 1984 (192) or December 1983 (51) was: Species Hatchlings Juveniles Adults TOTAL C. porosus 807 27 24 838 (192) Cre dONNSOnl . sie oa 2589----- 0 2589 (51) 2389 (192) PRODUCTION AND TRADE Skins are to be produced but production has not yet started (86). It was expected to begin production in 1985 for export to European and Asian markets (51). SOURCE OF ANIMALS The numbers of animals obtained from the wild up to mid-1983 were: Adults Juveniles 1982 - 3300 1983 5 - (86) Survival rate of hatchlings was 100% until unsuitable diet caused a loss of nearly 9%, the problem is now thought to have been resolved. In 1982 the operation was based on the harvest of hatchlings but in 1983 egg harvesting was to be tried as an alternative. Regulations are set by the Government to control wild capture (86). BREEDING None reported up to 1983, but the farm plans to be self-sufficient eventually. HUSBANDRY The crocodiles are kept in open-air enclosures with aquatic vegetation; feeding is on a daily basis with a mixture of poultry, fish and beef (86). The second partner in the operation runs a chicken farm which provides ex-production birds as the main food supply for the crocodiles (87). FINANCES The operation was financed by Mr Graham and a partner but is expected to become self-financing after production has been under way for a while (87). RESEARCH AND PUBLICATIONS Research was carried out by Alistair Graham in collaboration with the Conservation Commission of the Northern Territory (86). OTHER INFORMATION All wild animals in the N.T. remain the property of the Government so that control of the resource is entirely in their hands. Regular reports are made to the Government on all management activities, with a view to publication (86). 54 Australia Queensland NAME OF OPERATION Edward River Crocodile Farm Pty Ltd (formerly Applied Ecology Pty Ltd) Edward River, Cape York, Queensland 4871 Postal address: P.O.Box 669 Cairns Queensland 4870. DATE OF ESTABLISHMENT The operation started in 1973 and aimed to start production and commercial operation in 1984 (134). The farm was registered with the CITES Secretariat aS an approved captive-breeding operation for Crocodylus porosus in November 1984.

PRODUCTION AND TRADE The operation produces skins and live animals. In 1980 40 skins were produced under licence as part of a feasibility study for commercial production. When commercial production was envisaged in 1980, a figure of 3000 skins a year was the proposed output and this figure remained the production target for commercial operations to begin in 1984 (134). It is proposed that all killing and skinning Operations will be carried out on the farm and thus the farm staff have been instructed in the various skills required (133). Live animals have been sold to zoos, for research and to other crocodile farms. Live animal production 1980-83 (134): Year Number of animals Destination 1980 5 Zoos 1981 10 Zoos 1982 35 Zoos and research 1983 20 Breeding stock for another farm In 1980 40 skins were sold to destinations in Australia, France, Singapore and Italy. All live sales have been within Australia. All 55 Australia specimens and skins are accompanied by required state and/or federal permits (134). The first commercial export of 100 skins to Singapore took place in 1984. SOURCE OF ANIMALS The farm had received many wild-caught animals up to 1979. The operation was originally established primarily as a conser vation- -orientated project; so most of the animals were eventually released back into the wild. In 1979 wild capture ceased and the operation became a closed cycle (134). BREEDING C. porosus have been bred on the farm for a number of years. The breeding stock of about 100 females is kept separate from the rearing pens and eggs are hatched in an artificial incubator. Breeding success 1980-83 (134): Year Number bred Number survived in captivity. 30 days. 1980 179 140 1981 302 267 1982 591 561 1983 769 741 1984 1043 - The survival rate to 30 days has therefore increased from 78% in 1980 to 96% in 1983. It is anticipated that 70 clutches of C. porosus eggs will be laid on the farm in 1984/85. At a mean clutch size of 52 this would represent 3640 eggs (192). HUSBANDRY The large breeding crocodiles are kept in a natural enclosed lagoon covering about 20 ha with a water area, when full, of 13 ha. Hatchlings after incubation are kept in tanks in a large shed until they start to feed. From the tanks the young crocodiles are then transferred to a series of 16 pens all with continuously flowing water. The crocodiles are moved through the series of pens as they grow, until an age of 2-3 years when they are moved to ‘'finishing' enclosures. These enclosures are 2.2 ha each with l-ha water areas, and house the animals until they reach optimum size of belly skin width 40 cm and 1.5 m body length (about four years of age). The creek systems are drained and swept out six times a week, whereas the enclosures are permanent water areas. Bore water is pumped into all enclosures in the dry season. The breeding lagoon animals are fed once a week, those in the finishing enclosures five times a week, and those in the rearing pens six times a week, on a variety of foods including wild-pig, scrub cattle and fish, with a vitamin and mineral supplement (134). FINANCES The farm is run by a private company (Edward River Crocodile Farm Pty Ltd) owned and funded by the Australian Government through the Department of Aboriginal Affairs. In 1984 the operation was not self-financing (134). 56 Australia RESEARCH AND PUBLICATIONS Research is carried out by Professor Gordon Grigg, of Sydney University, who visits each year for 3-4 weeks with some of his post-graduate students (134). In the past there have been other research workers including Steve Garnett of James Cook University of North Queensland who looked at various components of the farming operation (133). OTHER INFORMATION The operation changed from Applied Ecology Pty Ltd to Edward River Crocodile Farm Pty Ltd on 1 July 1983. Applied Ecology used to be involved with a number of projects associated with wildlife management and the Aboriginal and Torres Strait Islander communities, but this involvement has now ceased. The farm was established primarily as a conservation measure but later shifted emphasis to researching the viability of crocodile farming and the development of a commercial farm (13). It is hoped that as soon as production, processing techniques and markets are firmly established, the farm will be handed over to the Edward River Aboriginal community. The operation should provide direct employment for at least 15 Aborigines and would form the basis of the community's first major income-producing enterprise. (16) NAME OF OPERATION Koorana Crocodile Farm M.S.F. 76, Rockhampton Mail Centre Rockhampton Queensland 4700. Operated by: John Lever. DATE OF ESTABLISHMENT 1981 SPECIES AND NUMBERS Crocodylus porosus WaIaL Crocodylus johnsoni 148 in June 1984 (192) PRODUCTION AND TRADE Production had not started by 1984, but is expected to involve skins and by-products such as gall bladders and ‘musk glands'. The skins are to be exported to French tanneries (161). SOURCE OF ANIMALS Crocodylus_porosus: native animals are collected after being declared rogue by the Queensland National Parks and Wildlife Service. Crocodylus johnsoni: 200 animals (60 adults and 140 juveniles) were removed from the wild under permit in conjunction with a Queensland National Parks and Wildlife Service research programme. It Was expected that no further introductions from the wild would be necessary and that the operation would become a closed cycle (122). Four C. johnsoni and two C. porosus have been obtained from other captive stocks. In July 1983 the farm was reported to be negotiating with Edward River Crocodile Farm to purchase 30 female C. porosus (161). BREEDING The C. porosus were put together for mating in 1983 for the first time (122). It is not known whether successful breeding occurred. 57 Australia HUSBANDRY The crocodiles are held in 25 concrete tanks with wire enclosures, 7 dams (reservoirs) and one lake. All of the crocodiles are fed fish and poultry (122). FINANCES The operation is financed by a private individual and was not self-financing in 1983 (122). RESEARCH AND PUBLICATIONS Research was planned in conjunction with the Queensland National Parks and Wildlife Service and the Capricorn Institute for Advanced Education (122). 58 BANGLADESH General Information: In 1982 Whitaker (198) proposed the establishment of a central crocodile hatchery and nursery and four model crocodile demonstration ranches. The main species involved would be Crocodylus porosus and Gavialis gangeticus. Breeding would be carried out on an experimental basis. The major part of the operation would involve taking C. porosus eggs from the wild in the Sunderbans and rearing them for skin trade and release to the wild. It was proposed that the system should be established by the Sunderbans Forest Department with the central hatchery situated at Dhangmari, Sutar Khali, Chandpai and the four model demonstration farms at Khulna, Dacca, Chittagong and Sythet (198). As far as is known no steps had been taken to implement the proposal by 1985. The plan was to rear C. porosus to 1m for release to the wild and to 1.75 m for cropping. The central hatchery would supply 6-months to l-year-old crocodiles to the Demonstration farms. The Demonstration farms' eventual output would be 250 skins a year, plus a number of yearlings for restocking the Sunderbans. Crocodylus palustris and G. gangeticus are considered unsuitable for this sort of ranching in Bangladesh because of their low populations. However, the Central Hatchery would hatch and rear some C. palustris from eggs collected at Bagerhat, near Khulna. The Dacca model demonstration farm would also hatch and rear some G. gangeticus from eggs collected at Rajshahi. A study of wild living crocodiles would need to be undertaken to establish a management scheme for Sunderbans crocodile populations and for identifying areas for restocking with farm-reared animals (198). In Bangladesh in 1982 it was estimated that there was a total captive population of three C. porosus, five G. gangeticus and three C. palustris (197). 59 BOLIVIA ASICUSA (Asociacion de Curtidones de Cueros de Saurios), based in Cochabamba and comprising four companies, Tomy, Alligator, Dorado and Moxos, all involved in the tanning and processing of caiman skins in Bolivia, was reported in 1982 to be establishing a crocodilian farm in Bolivia (46). In 1983 it was claimed that the stock included 2000 crocodilians comprising Caiman crocodilus crocodilus, Caiman crocodilus yacare, Melanosuchus niger and “another species of Caiman" (47). However Quaino, Director of "Moxos" Alligator Ranch, Casilla Correo No. 44, Trinidad-Beni, stated that his ranch was only in a very preliminary phase and contained only Caiman _crocodilus_in 1983 (151). It is extremely unlikely that any breeding has taken place on any farm in Bolivia. A report in 1982 stated categorically that no breeding had occurred at that stage (46). 60 BOTSWANA Two farms for Crocodylus niloticus are reported to have been established since 1983 in Botswana: NAME OF OPERATION Okavango Swamps Crocodile Farm (Botswana) Pty Ltd P.O.Box 448, Maun. Managing Director: John J. Seaman. DATE OF ESTABLISHMENT January 1983 SPECIES AND NUMBERS Crocodylus niloticus: In 1983 the farm held 70 adult breeding crocodiles, 80% of which were male. PRODUCTION AND TRADE It is hoped to sell live animals to other farmers and zoos. SOURCE OF ANIMALS 70 adult crocodiles have been captured in local drought areas where they were thought to be under threat. It was anticipated that in 1984 there would be another severe drought and facilities were being built to cater for a larger number of crocodiles. It was planned to collect 2000 eggs a year over the following three seasons. It was also planned to reinstate 5% of the l-m sized crocodiles into the wild (162). A number of crocodiles were caught in 1984 at Lake Ngami which was badly affected by the drought. Several nuisance crocodiles have been obtained after complaints of attacks on livestock or humans (144). BREEDING 2 The crocodiles had just started breeding in 1983. It was hoped that the breeding stock could be built up to 300 over the next three years (162). Successful breeding was also reported in 1984 (144). HUSBANDRY The animals are kept in near-natural pools in a typical Okavango back-water area. Water access is from a main stream nearby. There is a dual perimeter fence made of reeds. The pens are 45 m long and 40m Wide covered two thirds by water of varying depths with islands and the natural vegetation (162). A temperature-controlled building is used for rearing hatchlings (144). The crocodiles are reported to stop feeding for four months in the winter when the temperature falls below 20°C (144). They are fed on donkey meat and catfish (162). FINANCES It is intended that most of the income will be obtained from the sale and export of live animals. Tourists are also admitted to the farm (144). The operation was not self-financing in 1983, being supported by private investment (162). The farm employs 53 local people (144). RESEARCH AND PUBLICATIONS Research is planned in conjunction with the Rockefeller Refuge, Louisiana, USA (162). === * === ¥ ===¥*¥ === Another farm was reported to have been established in Botswana in 1984 by Mike Slogrove, the owner of a crocodile farm in Transvaal, South Africa (54). 61 BRAZIL No commercial crocodilian farming has taken place in Brazil but I.B.D.F. (Instituto Brasileiro de Desenvolvimento Florestal) has initiated some experimental farming of Caiman _crocodilus. One breeding centre operated by I.B.D.F. outside Manaus, the Centro Experimental de Criagao em Cativeiro de Animais Nativos de Interésse Cientifico e Economico (CECAN), formerly held small numbers of Caiman crocodilus and Paleosuchus trigonatus but these have since been disposed of. Melanosuchus niger is kept in small numbers only by zoos and research institutes. NAME OF OPERATION An experimental farm has been set up in Pantanal about 150 km from Pocone, Mato Grosso. The project is managed by: Instituto Brasileiro de Desenvolvimento Florestal (1.B.D.F.) Ed. Palacio Desenvolvimento, 12° 70.000 Brasilia-DF SPECIES AND NUMBERS Caiman crocodilus yacare: numbers unknown DATE OF ESTABLISHMENT 1981 OTHER INFORMATION The aim of the project is to evaluate the possibility of caiman ranching in the Pantanal. Eggs are collected from the wild, incubated and hatchlings are to be released later. Few results are available as yet. There is also some experimental work with capybara at the farm (154). 62 BRUNEI A combined fish and crocodile farming operation (Crocodylus porosus?) is under consideration. A feasibility study was being carried out in 1984 (43). 63 BURMA Only one crocodile farm is known to exist in Burma: NAME OF OPERATION The People's Pearl and Fisheries Corporation Crocodile Farm ( PPFC) Thaketa, Rangoon. Operated by: The Government of the Socialist Republic of the Union of Burma (63). DATE OF ESTABLISHMENT 1978 SPECIES AND NUMBERS Crocodylus porosus: about 900 were held in 1980 (63). PRODUCTION AND TRADE The main aim of the farm is to produce skins but it is thought that in 1983 no animals had reached marketable size (158). SOURCE OF ANIMALS Young animals are taken as hatchlings or yearlings from the eastern side of the Irrawaddy Delta where the PPFC has set up a number of collection centres. There is evidence that the total recruitment of crocodiles was being taken by the PPFC in the Tawbaing Chaung area (63). From 1978 to 1983 an average of 465 hatchlings were obtained from the wild each year (158). BREEDING The farm is intended to be self-sustaining when its breeding programme is fully established. Successful breeding was expected by 1983 (63). The farm has recently been successful in inducing nesting but most of the stock of hatchlings continues to come from the remaining wild population in the Irrawaddy Delta (158). HUSBANDRY Young animals are kept in a series of tanks and there is a 1.5-ha breeding/nesting enclosure (158). RESEARCH AND PUBLICATIONS Research is to be carried out by U. Aung Moe, under the direction of U. Than Nyunt (farm manager), with possible help from an FAO consultant, in an honorary capacity, if necessary. The proposed research is into food quality and quantity required for maximum growth rates (63). OTHER INFORMATION The crocodile farm is a large, modern, commercial enterprise modelled on farms in Thailand and Singapore (62). The PPFC has also proposed to turn Meinmahla Kyun, an island of some 50 square miles in the Irrawaddy Delta, into a "crocodile sanctuary’ where re-introductions from the the crocodile farm would supplement the remaining wild population and provide the basis for eventual sustained- -yield harvest (158). The farm was reported to be in need of technical and development assistance in 1984 (201). 64 CAMEROON A French/Belgian concern is reported to be planning a crocodile farming project in the Cameroon with the intention of exporting skins as): 65 CHAD An experimental programme to evaluate the possibilities of crocodile farming (Crocodylus niloticus) was undertaken from 1972 to 1973 under the auspices of the Centre Technique du Cuir, Lyon (119). The farm was situated at Djimtilo, a vilage near Lake Chad, and funding was partially supplied by the Centre Technique Forestier Tropicale (CoD Sree iy 45 bis Avenue de la Belle Gabrielle, 94130 Nogent-sur-Maine, France (119). Although much valuable information was obtained during this experiment, it was not intended to be a commercial proposition but merely to assess the possibilities of breeding crocodiles under controlled conditions. It is understood that the experiment was discontinued in 1973 (188). An experimental crocodile farm was reported to have been started in 1943 but since the "recent disturbances" it is believed to have been abandoned (43). 66 CHINA A substantial investment has been made in alligator ranching/ farming by both national and local authorities in China. There is a growing number of operations, mainly intended as conservation measures, but there is considerable potential for sale of live animals or products derived from them (189). There are unconfirmed reports that sales of alligators may have taken place (29).

NAME OF OPERATION Xiadu Commune Tree rarm Xuancheng County, Anhui Province. Operated by: Forestry Bureau, Anhui Province. SPECIES AND NUMBERS Alligator sinensis: The station held about 90 individuals, mostly adults, in July 1981 (89). By summer 1982 Huang reported some 130-140 animals on the farm (190). In 1983 he reported the presence of over 100 adults and 380 juveniles (98). PRODUCTION AND TRADE Chinese alligators are not known to be used for food or skins (190), but there are unconfirmed reports of commercial sales from this farm (29). SOURCE OF ANIMALS Peasant excavations of alligator dens are frequent in mountainous areas of Anhui Province. Animals captured are sold to dealers who, in turn, try to sell them to zoos or to the alligator farm. Local residents are being encouraged to bring alligators that they capture to the farm rather than kill them or sell them elsewhere. The farm will pay in excess of one yuan a pound (US$1.32 kg-l). Alligator eggs are also bought at one yuan each. It is reported that even eggs that have been rotated, and so are probably dead, are bought (190). Local workers are also asked to inform farm personnel of the presence of nests containing eggs within their communes (89). BREEDING No captive breeding is known but wild-collected eggs are incubated. Over 200 wild-taken eggs were incubated in 1981: approximately 40 hatched of which 24 survived until hibernation in October; 18 survived the winter but all died before the summer of 1982 (190). In 1983 300 alligators were sucessfully hatched (201). HUSBANDRY In 1981 the farm consisted of two triangular concrete pools with sloping bottoms, c. 10 m x 10 m x 15 m (curved side), the maximum water 67 China depth being 2m but not constant; several ‘natural type' pools dug straight into the earth, each containing four to seven adult female alligators, and measuring approximately 4m x 5m x 3m deep but providing no cover for the alligators; and a large circular pool 30m in diameter with a circular central island 20 m in diameter and stocked with 60 adult alligators and several turtles (Chinemys reevesi). The large circular pool has concrete walls and a mud bottom, with a maximum water depth of 1m. The island has 0.3-m concrete pipes placed around its periphery in which the alligators shelter; it was also planned to plant the island with bamboo (190). The farm has no natural alligator habitat and no natural water supply above ground (190), but a large natural enclosure was scheduled for completion in 1984 (201). The alligators are fed several times a week on locally available freshwater fish and live ducklings (190). FINANCES The farm receives financial support from the Ministry of Forestry in Central Government (189). OTHER INFORMATION The farm covered an area of 89 ha in 1981 but there were plans to increase this to 3335 ha (190). == NAME OF OPERATION "Wan" Production Unit Cheunghing County (=Changhsing?)

NAME OF OPERATION Shanghai Zoo Shanghai. SPECIES AND NUMBERS Alligator sinensis BREEDING There has been considerable success in breeding Yangtze alligators. Five adults have had clutches of eggs ranging in size from 8 to 41. Eggs are laid early in the morning over a period of about 30-40 minutes. Incubation lasts 67-83 days. 12 young were hatched in 1980 and 7 in 1981 (191). HUSBANDRY Growth rate varied with the feeding regime. Of three groups of young, the fastest-growing group reached 60 g in one month, 270 g after a year and 800 g after two years. Comparable figures for the slowest- -growing group were 24 g, 65 g and 230g Adults were fed on fish and waste from a slaughter-house (23). === *==--—%*---*-=— NAME OF OPERATION Ningpo Zoo Chekiang Province.

NAME OF OPERATION Estacion de Biologia Tropical Roberto Franco Station Villavicencio (Meta) Apartado aéreo 22-61. Operated by: INDERENA (Instituto de Recursos Naturales y del Ambiente). SPECIES AND NUMBERS Crocodylus intermedius: two pairs (127). Caiman crocodilus: 17 animals. Paleosuchus palpebrosus: 12 animals. Paleosuchus trigonatus: 5 animals. BREEDING C. crocodilus and P. palpebrosus have both bred several times at the station. OTHER INFORMATION The operation is an outstation of the National University, in Bogota, and carries out studies on the biology of crocodiles and turtles, with the aim of applying the information gained to conservation (128). NAME OF OPERATION Los Cocos Breeding Station Salamanca Island. Operated by: INDERENA (Instituto de Recursos Naturales y del Ambiente). SPECIES AND NUMBERS Crocodylus acutus: 30 were reported to be maintained in 1980, 3 adults and 27 juveniles. BREEDING A breeding programme exists but up to 1980 had yet to achieve results. Eggs were laid in 1977 and 1978 but did not hatch (126). === 2 === 2 = — *——— NAME OF OPERATION Cienaga Grande Management Station Cienaga Grande. Operated by: INDERENA (Instituto de Recursos Naturales y del Ambiente). SPECIES AND NUMBERS Caiman crocodilus fuscus OTHER INFORMATION Apparently only a few animals were kept at the station, which does not seem to be operating any longer. Of these some were stolen by local residents who sold them in Baranquilla, and the rest escaped during a flood (126). 71 COSTA RICA A commercial farm was being set up in the country in 1984 by a commercial company acting in conjunction with the Ministry of Agriculture. They had a stock of about 100 young animals, probably Caiman crocodilus, ranging from hatchlings to about three years old (153). 72 CUBA There are no commercial crocodile farms in Cuba but there is one large conservation-orientated operation at Laguna del Tesoro. A second conservation operation was established more recently at Tasajera, also in the Zapata Swamp. There are reports that some skins are sold from the farms. NAME OF OPERATION Centro de Cria de Cocodrilos Laguna del Tesoro (Treasure Lagoon) Zapata Swamp. Operated by: Ministerio de la Industria Pesquera, Direccion Ramal de Acuicultura. DATE OF ESTABLISHMENT 1965 (92) SPECIES AND NUMBERS The total adult population was about 1000 in 1981 of which about 80% were Crocodylus_rhombifer, 5% were Crocodylus_acutus and 15% hybrids of these two species. There were also about 5000 immature crocodiles of a similar species composition; these were made up of about 2500 from the 1981 hatch, 1500 produced during 1979 and 1980, and 1000 of older age groups (64) PRODUCTION AND TRADE Some of the large crocodiles have been slaughtered for hides (185), meat is sold locally and skins are exported (92). Considerable quantities of skins of unknown source are said to be exported from Cuba, especially to the German Democratic Republic (188). SOURCE OF ANIMALS The local populations of both species were moved to the operation to ensure their survival (185). Over the years almost 36 000 C. rhombifer have reportedly been removed from wild populations and placed on experimental farms (130). BREEDING The two species have inter-bred in the past, but recently attempts have been made to keep the two stocks apart. The breeding (and presumably mating) seasons of the two species show little overlap which must reduce inter-breeding. Female hybrids are certainly fertile but the fertility of the male hybrids is unknown (64). Most eggs are laid on iSlands in the lagoons. Up to 25 eggs are collected from each nest and hatched in incubators (92). Some eggs are hatched in semi-natural conditions, buried in soil in a hatching enclosure (64). When the young are born they are removed to rearing pens before being put back into the lagoons. It is reported that the mortality of the C. acutus young is much higher than that for C. rhombifer (135). In 1981 eggs were collected from 600 nests. The mean clutch sizes were C. rhombifer 35 eggs, C. acutus 48 eggs, and hybrids 42 eggs. The hatching rate for all groups was similar and averaged 46%. The total number of young hatched was about 10 000 (64). HUSBANDRY The farm covers an area of 15 ha and includes breeding pens, rearing pens, brooding pens, infirmary pens and administrative buildings. It has a workforce of 23 people. Most of the adult crocodiles are kept in a large (8 ha) breeding pen, but there is also a smaller breeding pen containing only C. rhombifer, selected as having the best specific characteristics (64). 73 Cuba The animals are fed fish and scraps from a cattle slaughter-house and some rotted fruit (92). Small crocodiles are fed on fish 10-12 cm long three to five times a week; adults are fed twice a week. Freezer facilities are not available, the food being obtained locally and brought by truck as required (64). The young grow at about 1.5 ft (0.46 m) a year, and reach adult size at about 7 years (92). They are kept in small lagoons with natural vegetation and are separated by age class to prevent the older animals from killing the young (135). Mortality is high during the first year of life but decreases thereafter (64). RESEARCH AND PUBLICATIONS There are no details of published research but many of the details quoted by Ottenwalder (135) are translated from: Anon (1979).

OTHER INFORMATION The operation was set up to preserve the two species involved. Some of the C. rhombifer were moved to the Tasajera operation to breed pure individuals of the species (185). It is hoped to release pure-bred C. rhombifer into Zapata Swamp (92). Up to 200 tourists a day, mostly from Havana, visit the farm but no entrance charge is made (64). sas ¥ === === %*¥ === NAME OF OPERATION Tasajera southwest of Zapata Habana Province. Operated by: Ministerio de la Industria Pesquera, Direccion Ramal de Acuicultura. DATE OF ESTABLISHMENT Thought to be 1978 or 1979 (135). SPECIES AND NUMBERS Crocodylus rhombifer PRODUCTION AND TRADE The operation seems to be conservation-orientated. SOURCE OF ANIMALS The animals were transferred from the farm at Laguna del Tesoro in order to breed pure captive C. rhombifer as the number of crocodiles produced at Laguna del Tesoro that were pure-bred was not thought to be sufficient (185). 74 ETHIOPIA In 1981 a proposal was put forward for a crocodile farm, expected to grow from pilot phase to producing about 20 000 skins a year within five years. Farming of fish, rabbits, rodents and fowl as food was considered. No further progress is known (43). In 1983 the FAO provided assistance to a crocodile management programme. Funds were made available in 1984 for a Government pilot rearing station at Arba Minch near Lake Abaya. Fishery wastes and associated culled wildlife were to be used as food. Construction was under way in 1984, and it was hoped to increase production to 1500 skins a year in five years (43). The farm covered an area of 3 ha and was surrounded by a fence 2 m high. It included a block of 50 ponds for hatchlings, and incubation facilities were also planned. Suitable nesting sites around Lake Abaya had been surveyed and it was hoped to collect the first batch of eggs for hatching on the farm in 1985 (58). 75 FRANCE It was reported in 1985 that experiments were to be conducted to test the feasibility of rearing crocodilians in Provence using thermal effluent from a C.E.A. nuclear power station at Bolléne, near Avignon. It was planned to conduct growth trials using “young crocodiles" (Caiman crocodilus? Melanosuchus niger?) imported from "Guyana" (French Guiana?). If these proved successful financial backers would need to be sought. The nearby tanneries of Annonay or Saint-Chamond were mentioned as being potentially interested (99). 76 GREECE Plans for a crocodile farm were reported in 1984 but recent information suggests that progress may have been delayed.

HUSBANDRY Breeding stock are to be kept in outdoor display ponds but there are also to be some indoor ponds for rearing juveniles (153). FINANCES The operation intends to derive a large part of its income from tourists (153). OTHER INFORMATION The Ministry of Agriculture in Greece is co-operating in the establishment of this farm. at INDIA General Information The Government of India initiated a Crocodile Breeding and Management Project as a conservation measure in 1975 with preliminary surveys being undertaken in 1974. The project operated until 1982 on advice from a UN/FAO Chief Technical Adviser with finance from UNDP (89). The project involves collecting eggs from the wild, incubating them and rearing the hatchlings up to a size at which they can be released. Thirty-four crocodile rehabilitation stations have been established throughout the country comprising 13 specially created sanctuaries and a further 21 National Parks or other sanctuaries, covering a total area of 20 399 km2. Crocodiles have been released in the majority of these areas. The numbers. of each species handled under the scheme are given below (167): Eggs Hatchlings Animals handled handled released Gavialis gangeticus 6000 4000 1185 Crocodylus porosus 2500 1700 408 Crocodylus palustris 9000 6000 502 Captive rearing or breeding schemes for crocodilians in India (167).

Captive rearing or breeding is being attempted at the locations listed below. Sites at which breeding has been attempted or successful are indicated. All of these schemes have been established since 1975. Captive breeding has also been achieved at five zoos and at the Madras Snake Park (167). The rehabilitation schemes which have taken place within India have shown the potential of C. palustris as a subject for commercial utilization through farming or free-range sustained-yield exploitation (89). Following clearance from the Indian Bureau of Wildlife, a proposal was under consideration in 1984 for the experimental farming of C. palustris under closed-cycle conditions (167). Selected operations: NAME OF OPERATION Amaravathi Crocodile Farm. One of two main crocodile rearing centres (the other being Sathanur Reservoir) of the Tamilnadu Forest Department is at Amaravathi Reservoir, where Crocodylus palustris has been bred since 1983. SPECIES AND NUMBERS Crocodylus palustris: about 600 reported (70). PRODUCTION AND TRADE Currently an experimental commercial operation to assess. the feasibility of crocodile farming: it is hoped to commence production by 1990 (165). SOURCE OF ANIMALS Eggs are collected from Dhuvanam area of the Amaravathi Reservoir and taken to the farm to be hatched and reared. 15 nests are known in the wild in this area (70). BREEDING The farm has a breeding stock of 8 adults, which produced 5 nests in 1983. This stock is from the 1975/76 wild-caught females. A low hatching percentage of 20-30% is thought to be due to the intense heat in the hatchery (70). HUSBANDRY The crocodiles are reared in concrete ponds which are being altered as they are thought to be too shallow. Water comes chiefly from a percolation well. FINANCES The farm was set up by the Tamilnadu Forest Department. OTHER INFORMATION After the success of the Rehabilitation Programme of Gavialis gangeticus and Crocodylus palustris, the Government of India decided to make a start with crocodile farming (131). The current operation is a pilot project investigating the commercial viability of crocodile farming in India. It is likely that several of the other Indian states will also set up farming and ranching operations once the wild population is established (197). A proposed crocodile farm site of the Tamilnadu Forest Department is in Kilikudi Village, near Kallanai about 10 km from Tiruchirapalli. In 1974 the proposed area was described as follows: “at the proposed 79 India site is a three to four acre (1.2-1.6 ha) pond, 6-10 m deep. About 20 crocodiles are believed to be naturally resident and breeding there, where they are protected and regularly fed by the Forest Dept. At night, they move between the pond and the Grand Anicut of the Coleroon River, about 300 m away." (193) =s=*¥ === % ===%* === NAME OF OPERATION The Madras Crocodile Bank Trust Vadanemmeli Village, Perur P.O. Mahabalipuram Road Chingleput District Madras-603 104. Managed by: Romulus Whitaker. DATE OF ESTABLISHMENT In 1975 an Indian Government/FAO/UNDP project was started, to rehabilitate wild populations of crocodiles. Madras Crocodile Bank Trust was set up as an offshoot of Madras Snake Park (a non-government trust) in 1975, with help from the World Wildlife Fund (197). The Crocodile Bank Trust is situated about 40 km South of the Madras Snake Park. In 1977 the Trustees agreed to set up the Madras Crocodile Bank as an international bank to establish a gene pool of every species of crocodilian. This received the approval of the IUCN/SSC Crocodilian Specialist Group in 1978 (202). SPECIES AND NUMBERS Crocodylus palustris: 8 breeding females, 1100 immature (201) Crocodylus porosus: 1 breeding female, 48 immature (202) Caiman crocodilus: 4 breeding females, 109 immature (202) Gavialis gangeticus Alligator mississippiensis PRODUCTION AND TRADE This is a conservation operation. 465 C. palustris were supplied to State rehabilitation programmes from 1976-1982 (202).

FINANCES Income from the entry fees of 25 000 visitors a month makes the Crocodile Bank financially self-sufficient. Crocodiles supplied to State projects and National Parks are paid for on the basis of their feeding and maintenance costs alone, at no profit (197). 80 INDONESIA General Information Crocodiles have been exploited in Irian Jaya for some time and there is evidence that the wild populations have declined through Over-hunting (142). At the fifth meeting of the Conference of the Parties to CITES in 1985 a proposal was approved whereby the Indonesian population of Crocodylus porosus was transferred from Appendix I to Appendix II with the imposition of a maximum annual quota of 2000 skins and provision that they should all be tagged. A survey was carried out in late 1984 which ascertained that considerable hunting was still occurring in spite of the ban which was Supposed to have been in force since 1980 and that several thousand skins annually were being illegally exported from Irian Jaya. Many local crocodile populations had been wiped out and most of the others were severely depleted. Crocodylus porosus was particularly severely affected as it occurs in the larger, more accessible waterways than Crocodylus novaeguineae (204). It is the expressed aim of the Government to institute a farming programme similar to that of Papua New Guinea (61), and a scheme was initiated in 1980 when legislation protecting the wild population was enacted. The project is being carried out under the title ‘Crocodile conservation and industry development in Irian Jaya', involving a number of consultants, which started with a survey in October 1984 for an initial period of four months (143). The purpose is to promote the conservation of crocodiles by utilizing them as a resource to benefit the indigenous communities. The primary aim is to establish the most suitable areas to set up collecting farms, determine the numbers of crocodiles that will need to be collected, investigate the economics, and recommend appropriate legislation. It is proposed that skin exporters will only be able to obtain live crocodiles from collection farms, and that strict quotas will be set for the exploitation (34). Farming was started in 1976, but the Government stopped further expansion until the ability of wild stocks to support a farming industry had been assessed. The system relies on the capture of young crocodiles from the wild, and rearing them until they are large enough to slaughter. In 1980 there were 4000-5000 crocodiles on farms in Irian Jaya. The farms were reported to be of varying size and were, on the whole, poorly managed and uneconomic. Most of the farms started because the Government obliged all companies wanting to export skins, to operate a crocodile farm. Therefore economics have not been of prime importance, but rather the farms have been established to comply with Government regulations. However, by 1980 it had been realised that farms would have to be more efficient as the wild population would not Support indiscriminate hunting indefinitely. At that time it was found that management was poor on the existing farms, that pen design and general health of the crocodiles was only fair and that there was a great need for management training and advice (121). The next survey, conducted in late 1984, reported a_ total population of 4051 crocodiles on 12 major farms in Irian Jaya but with no indication of the species composition. The survey concluded that the survival of the crocodile population depended on the establishment of an adequately controlled ranching programme. Initially it was 81 Indonesia recommended that the scheme should be confined to C. novaeguineae, as the C. porosus populations were too severely depleted to Sustain any exploitation. Three large rearing farms should be established in Merauke, Jayapura and Sorong, each to house 5000-10 000 crocodiles. A scheme to buy 7000-10 000 young C. novaeguineae annually from villagers and take them to about 25 collecting farms should be established, and the villagers should be given shares in the farms to provide them with a long-term interest. Resources of trash fish available were assessed to be adequate for such a scheme (101). Everywhere in the Mamberamo delta and along the river up to Kasonoweja (Pioniersbivak) local people were reported in 1979 to keep crocodiles in often very dirty enclosures fenced by corrugated iron (112). Scattered small-scale enclosures were also mentioned in 1984 (101). Skins of crocodiles reared by the villagers are often bought by the local government employees who then sell them to the large trading companies. The main centres for crocodile hunting in the area are Merauke, Jayapura, and Serui on the island of Japen (112). Most of the skins exported go to Singapore; in 1980 the average skin size exported was 15.5 inches (38 cm) belly width; of these skins 10% were Crocodylus porosus and 90% Crocodylus novaeguineae (121). The prices quoted in Paris in 1984 for salted skins were US$9 and US$12 per inch belly width (US$3.54 and US$4.72 cm-l) for Cc. novaeguineae and C. porosus respectively. It was estimated that the sale of by-products could increase the value of each crocodile by a further 30% (101). According to official figures in the proposal submitted to the fifth CITES Meeting (32) the annual totals of skins exported from 1980 to 1983 were 4953, 200, 360 and 1180 . There are indications that the true level of exports was considerably higher than this (101). It has been reported that rearing farms are “obliged to release to the wild habitat at least 10% of their rearing products, and they are obliged to develop themselves fully into breeding farms" (32). There is no evidence that any deliberate releases have taken place and no breeding taking place on farms in Irian Jaya (143), although limited breeding has been reported in Java. The survey in 1984 concluded that none of the farms in Irian Jaya was commercially viable, and that the most of the skins exported were from the wild (101). A list of 15 registered crocodile farming companies was supplied by the Director General of Forest Protection and Nature Conservation in 1984, 12 in Irian Jaya and 3 in Sumatra (157): Le C.V.

It was reported that three of the registered farms (presumably numbers 1, 2 and 4) in Irian Jaya were not operational in 1984, but other farms were reported to be in existence (101). The total number of crocodile farms in Indonesia is thus thought to be in excess of 17 farms, comprising something over 12 in Irian Jaya, three in Sumatra, one in Java, one in the Mentawai Islands and possibly a few in Kalimantan. 83 Indonesia Irian Jaya The following operations were described in surveys of Irian Jaya conducted in 1980 and 1984, the species involved were C. porosus and/or C. novaeguineae.

There are no indications that this farm was continuing to operate in 1984 (101). PRODUCTION AND TRADE Skins. The farm bought young crocodiles at 5- to 8-inch (13- to 20-cm) belly width and slaughtered them at a belly width of about 12 inches (30 cm) 18-24 months later (121). SOURCE OF ANIMALS These came from local wild populations. In October 1977 the farm received 200 young crocodiles from the Mamberamo area (112).

Management was reported to be poor but the crocodiles were healthy (121). 90 Indonesia Java There are a few rearing farms in the vicinity of Jakarta, which are dependent on eggs and young taken from the wild. Very little breeding takes place on these farms (112). Details of one farm at Yayasan were given in 1980 when it was reported that relocation was being considered (121). It is thought that this may now have been achieved and that the new farm is located at Pluit, North Jakarta. Details of both sites are given: NAME OF OPERATION Jakarta Crocodile Farm Yayasan, Jakarta, Java. Operated by: Lukman Arifin. DATE OF ESTABLISHMENT 1959 SPECIES AND NUMBERS In 1980 it was reported that 500-600 crocodiles were being held, including 120 Tomistoma_schlegelii, some C. porosus and C._siamensis (121). PRODUCTION AND TRADE The operation derived income from tourists and from sale of live animals. No details of skin production were obtained (121). SOURCE OF ANIMALS 90% of the animals were obtained from Sumatra and Kalimantan. They were purchased at 40-70 cm length but the smallest of these usually died (121). BREEDING In 1978 large numbers of eggs were laid but few hatched and none Survived two weeks. In 1979 the eggs laid were transferred to artificial nests but only 15 hatched; several of the hatchlings died and the remainder were being kept in an open plastic bucket and were looking week. They had deformities indicative of incorrect nest temperatures. It was reported that the owner's knowledge of crocodile biology was not sufficient to succeed with crocodile propagation. It Was thought that the farm would have to be relocated in order to Succeed with a breeding programme, as the existing facilities were inadequate (121). HUSBANDRY The ponds were of insufficient depth and much fighting occurred. The nesting boxes were too small and contained little nesting material. Breeding C. porosus and C. siamensis were being kept together under crowded conditions (121). FINANCES The farm was open to the public and claimed to have an attendance of 4000 a week (121). OTHER INFORMATION The stock was thought to have great potential for breeding and production, however both the management and conditions in 1980 were unsuitable (121). 91 Indonesia It was reported that a new crocodile farm had been created at Pluit, North Jakarta (24). It is not clear whether this replaced the farm at Yayasan, but this is thought to be the case as it was also run by Mr Arifin: NAME OF OPERATION ? Crocodile Farm Pluit, North Jakarta, Java. Operated by: Mr Arifin. DATE OF ESTABLISHMENT The farm was planned by and received approval from the Governor in 1976 (24). SPECIES AND NUMBERS In 1984 there were reported to be 500 crocodiles at the farm, species unknown (24). PRODUCTION AND TRADE The operation derives income from tourists and provides displays, such as wrestling with crocodiles and snakes. Food is also sold, snake sate, obon made from snakes and monitor lizards, and various medicinal preparations for the treatment of skin diseases and irritations (24). BREEDING The farm was reported to be used for crocodile breeding (24). HUSBANDRY The farm has a total area of 2 ha, and was reported to be extremely overcrowded. 9 crocodiles had already died of disease in 1984. The water in the ponds was said to be "brackish", and funds were not available to rectify this (24). FINANCES The new farm was reported to be receiving fewer visitors than the old farm and it was suggested that the whole farm needed upgrading if it were to provide a worthwhile recreational facility (24). The farm was opened with the assistance of the Jakarta administration as part of the Pluit Environmental Development Project. OTHER INFORMATION The farm also keeps other species, including snakes, which are used in the displays (24). 92 Indonesia Sumatra The Director General of Forest Protection and Nature Conservation listed three farms in Sumatra (numbers 13-15 in the list) in 1984 (157). Details were acquired of a farm near Medan, which probably corresponds with number 15. NAME OF OPERATION A crocodile farm is located at a village 12 km from Medan: Desa Asam Kumbang Kecamantan Pasar Lima Medan North Sumatra. Managed by: Mr Lo Than Muk. A breeding licence for three years was granted to C.V. Reptil Corporation, Medan, on behalf of the farm in 1981 by the Direktorat Jenderal Perlindungan Hutan dan Pelestarian Alam. Renewal of the licence was delayed in 1985 until further clarification of details of the farm was obtained (169). DATE OF ESTABLISHMENT The farm started in 1959 in Jalan Gurami, with 12 crocodiles, but when the stock increased to 200 the farm moved to a new, larger site (36). SPECIES AND NUMBERS Crocodylus porosus: 1138 (including 311 females "in nature") Tomistoma schlegelii: 12 (169) The farm was reported to have 200 breeding females in 1985 (36). PRODUCTION AND TRADE The farm is reported to sell skins (36). SOURCE OF ANIMALS No animals have been obtained from the wild since 1975, and all new stock is bred on the farm (169). BREEDING Breeding is reported to have first occurred in 1979 when 200 eggs were hatched. It is reported that the 200 breeding females now produce "a minimum of 6000" hatchlings a year (36). These figures seem unlikely to be correct. The maximum hatching success is reported to be 80% (169). HUSBANDRY The farm covers an area of 0.539 ha, comprising (169): Earth pond for mature females 900 m2 Cement pond for mature females 750 m2 Cement pond for young 230 m2 Earth breeding pond 2437 m2 Housing and other 1073 m2 Food is obtained from one shrimp enterprise, 20 poultry farms and C.V. Reptil Corporation in Medan (169). FINANCES The farm has been open to tourists since April 1983 (169). Entrance fees were Rp300 for adults and Rpl50 for children in 1985. 300-400 people visit the farm on Sundays (36). 93 Indonesia Kalimantan When the wild population became too scarce to support hide hunting, owing to over-exploitation and habitat destruction, eggs and young were captured for rearing in farms in Kalimantan, Java and Singapore. A number of these farms were in operation in Kalimantan at Samarinda on the Mahakam River, and at Tanjung Redeb on the Berau River, and at Bandjarmasin. Most of these farms were closed by the mid-1970s because the growing rarity of the wild crocodiles made it difficult to secure the eggs and young needed (112). Mentawai Islands A rearing farm for eggs and young taken from the wild was reported at Sikakap on Pagai Island (112). 94 ISRAEL In 1985 there were two crocodilian farms in Israel, but one of the companies, which has crocodile-farming interests in several countries, intended establishing other farms in the country in the future. NAME OF OPERATION Alligator Farm Hammat Gader Hot Springs Hammat Gader D.N. Rammat Hagolan 12480. DATE OF ESTABLISHMENT August 1981 SPECIES AND NUMBERS Stock in 1983 (49): Alligator MiSSisSippiensis: 302 Crocodylus niloticus suchus: 4 Osteolaemus tetraspis osborni: 3 PRODUCTION AND TRADE The operation in 1983 was run solely for tourists but it was intended that live sales to zoos and commercial operations would take place in the future. SOURCE OF ANIMALS In 1981 120 A. mississippiensis were obtained from a farm in Florida. four 0. tetraspis and four C. niloticus were subsequently obtained from the University of Tel-Aviv (48). BREEDING The initial stock of alligators is reported to have come from farm-bred alligators making the stock born on this farm, in effect, second generation captive-bred. However A. mississippiensis has not yet been bred through two generations on the farm. The farm incubator has a capacity of over 300 eggs (49). The numbers of A. mississippiensis bred in 1982/83 were as follows: Year Number bred Number survived 30 days 1982 4 4 1983 184 180 (49) HUSBANDRY The animals are kept in one large pond (4000 m2) divided into three sections, five small concrete pools (each 1.5 m3) and a hothouse with seven pools. The large pond is surrounded by 5000 m2 of grass and contains a natural swampy area. It has a constant flow of spring water at 28°C. Even on the coldest nights the temperature in the large pool was not found to fall below 20°C and in the small pools it Was in excess of 25°C. This is sufficient to prevent the onset of Winter dormancy and the animals were found to be eating 60-70% of their Summer diet during the winter. The animals are fed 50% poultry, 30% beef and 20% fish, the proportions varying with availability, at about 8% of body weight each week (48). FINANCES The operation is self-financing as part of a large tourist complex. 95 Israel RESEARCH AND PUBLICATIONS Results were presented at the 6th working meeting of the IUCN/SSC Crocodilian Specialist group (See 48). Research is carried out by the farm staff, in co-operation with the University of Tel-Aviv. 10% of the eggs are given to the University for research, after which the hatchlings are returned to the farm. OTHER INFORMATION The farm is situated in a region of warm springs in the vicinity of the Yarmuk river. There are plans to expand the population of alligators and eventually to sell excess stock of one-year-olds, to commercial operations. The operators would also like to increase their range of species and to attempt breeding of other species (49). NAME OF OPERATION Clal Crocodile Farms Ltd 5 Druyanov Street Tel-Aviv 63143. General Manager: Shlomi Ranot. The farm is situated at Kibbutz Ganshmuel, 60 km North of Tel-Aviv and 5 km from the coast. DATE OF ESTABLISHMENT The first crocodiles were obtained in November 1984. SPECIES AND NUMBERS Stock in 1984 (153): Crocodylus niloticus: 5 adult males 40 immature males (2 m, 5 yr-old) 160 immature females (2 m, 5 yr-old) PRODUCTION AND TRADE The operation intends to produce skins eventually but also admits tourists. It is hoped to supply breeding stock which may be used by other farms to be set up in Israel by the company. The animals at present on the farm should breed in 1986, in which case the first skin production would be in 1989 (153). SOURCE OF ANIMALS All the animals were purchased from farms in Zimbabwe in November 1984. It was hoped to obtain some additional hatchlings from the same source (153). BREEDING The breeding stock should be mature in 1986 (153). FINANCES The operation intends to derive a large part of its income from tourists (153). OTHER INFORMATION Clal Crocodile Farms Ltd owns other crocodile farms in Kenya and Greece, and intends setting up a total of 7 farms in other countries, including the Caribbean and Israel. 96 ITALY Only one crocodilian farm is reported to have Operated in Italy, but it is now thought to have closed down. NAME OF OPERATION Compagnia Internazional Allevamento Animali Esotici (C.I.A.A.E.) Commune di Presicce nr. Brindisi Provincia Di Leceo. DATE OF ESTABLISHMENT 1980. No recent information regarding this farm has been received and it is presumed to be no longer in existence. SPECIES AND NUMBERS Claimed to be “Caiman latirostris originating in Colombia" (147), however this species does not occur in Colombia (89) and no captive sources are known; so the animals must either have originated elsewhere or be of a different species, probably Caiman crocodilus. There were 406 surviving caiman in January 1981 (147), PRODUCTION AND TRADE Skins were reported to be provided to the Italian leather industry. SOURCE OF ANIMALS The entire stock originated in Colombia, supplied by a reptile dealer named Simon Daza, of Baranquilla. In December 1980 3000 animals were imported to Italy for the farm, and a further 1500 were due to arrive on 20 April, 1981 from the same source (147). BREEDING None. = HUSBANDRY The farm was surveyed by A.C. Pooley in January 1981. The 3000 caiman which were to form the initial farm stock left Colombia during the Colombian summer period all packed in one crate, suitable for only 1000 animals at the most, and arrived in Italy during the Italian winter when temperatures were around 0°C. About 1500 animals died before reaching the farm. Between the last week of December 1980, and the second week of February 1981 a further 1094 animals died, probably due to Salmonella poisoning and fungal disease. The remaining 406 animals were still being kept in poor conditions at the time the farm was surveyed and it was estimated that 100-150 were on the verge of death. It was suggested to the Managing Director of the firm, Senor Lili del Saudia, to postpone the further order of caiman from Colombia (147). The animals were reportedly kept in ponds which were “overcrowded, unsanitary, Stagnant, surrounded by faeces-laden sand, and with insufficient heating". They had been fed on a diet of fatty mince and were suffering from malnutrition (147). PINANCES The operation was privately financed, with backing from the Italian reptile leather industry (76). 97 IVORY COAST In 1980 a consultant was engaged by the firm FGU-Kronberg Unternehmensberatung GMB Kronberg, F.R. Germany, to advise on the potential for crocodile farming in the Ivory Coast in connection with the German Wildlife Project. Interest centred on Crocodylus niloticus and Crocodylus_cataphractus. Surveys revealed severe depletion of crocodile populations which were not thought capable of sustaining commercial ranching schemes at that stage. It was recommended that a pilot scheme at Abidjan Zoo be expanded to develop husbandry techniques for commercial farms in the future, and to supply crocodiles for restocking. In 1981 the zoo held 7 Osteolaemus tetraspis, 4 Crocodylus niloticus and 3 Crocodylus cataphractus (52). Nile crocodiles are also kept in a moat surrounding the presidential palace in Yamoussoukro. It is not known whether any breeding has taken place there. 98 JAMAICA There is reported to be one crocodilian farm in Jamaica, primarily orientated towards tourists: NAME OF OPERATION Swamp Safari, situated about 20 miles East of Montego Bay. The farm is owned by the Tourist Board of Jamaica but is held on a five-year lease by a commercial company, Cherokee Enterprises. DATE OF ESTABLISHMENT About 1970 SPECIES AND NUMBERS Crocodylus acutus: approximately 50 in 1984, BREEDING 22 young were hatched in 1984. OTHER INFORMATION The farm is primarily a tourist attraction but commercial production is apparently under consideration (153). 99 JAPAN The Atagawa Tropical Garden and Alligator Farm, Shizuoka, Japan, is a long-established display farm holding a very wide variety of crocodilian species. It is situated in a area of thermal springs which are used to heat the crocodile ponds (100). It acquired five Crocodylus johnsoni from the Northern Territory of Australia in 1984 at which time its stock also included Crocodylus porosus and Gavialis gangeticus (27). Eight captive-born Crocodylus moreletii, one of the few species missing from the collection, were supplied by the Atlanta Zoological Park, USA, in 1984 (33). The farm caters purely for tourists and, so far as is known, does not engage in skin sales (100). 100 | : KENYA There are two crocodile farms in Kenya, both situated near Mombasa: NAME OF OPERATION Baobab Farm Limited P.O. Box 90202 Mombasa. Managing Director: R.D. Haller. DATE OF ESTABLISHMENT The farm is primarily concerned with arable crops, domestic stock and fish (tilapia) culture (91), as part of a rehabilitation project to reafforest a worked-out limestone quarry. In 1975 crocodile hatchlings were introduced as part of the ecosystem (43). SPECIES AND NUMBERS Crocodylus niloticus: 9 adults 600 hatchlings in 1984 (43). PRODUCTION AND TRADE In 1977 the Government of Kenya passed a law forbidding the sale of most wild animal products in the country. This has prevented the farm from operating commercially. Crocodile farming is being developed for future production when allowed. This would probably be based on skin production (116). SOURCE OF ANIMALS The original stock were wild-caught as hatchlings in 1975. Of these, 9 adults survived in 1984. Since 1982, eggs have also been collected from the wild (43): 211 in 1982, 685 in 1983, and 60 in 1984 (43). HUSBANDRY The crocodiles are kept in tanks of water supplied by run-off from the fish tanks. The pens range from 20 to 600 m2 with natural or artificial ponds and are surrounded by concrete walls or diamond-mesh fences. Tilapia of non-commercial size which are discarded by the fish farm, or carcases from the livestock section are provided as food (43). BREEDING The captive-reared adults have bred since 1982; 9 young were hatched in 1982 and 13 in 1983 but all failed to survive. 25 hatched in 1984 and two of these survived for 30 days. It was hoped to supplement the breeding stock with some wild-caught nuisance animals (43). The following success with the hatching of wild-collected eggs has been reported (43): Eggs Eggs Survived collected hatched 30 days 1982 211 198 189 1983 685 542 505 1984 60 56 52 FINANCES The company is a subsidiary of Bamburi Portland Cement Co. Ltd and all research is funded by a grant from the parent company. 101 Kenya Some income is obtained from tourism as part of a larger Nature Trail complex which was opened in 1983 (43). RESEARCH AND PUBLICATIONS Research is conducted by R.D. Haller & J.D. Balarin on feeding rates, grading, pathology, pen design, breeding and social behaviour as well as census surveys of the wild population (43). Balarin, J.D. (1982).

Organiser: Clal Crocodile Farms, Israel. The crocodile farm is located in a 20-acre (8.1-ha) disused quarry at Nyali, north of Mombasa. DATE OF ESTABLISHMENT Probably late 1983 (170). The first phase of construction, comprising a tourist centre and aquascape of 1-2 ha of ponds was completed in 1984 when the venture was opened to tourists (43). SPECIES AND NUMBERS C. niloticus, target stock of 20 000 by 1986 (28). The original stock of 650 in 1983 (28) has been supplemented by hatchlings in 1984 believed to amount to some 250-300 (43). PRODUCTION AND TRADE Full production, once achieved, should be 3000 skins a year with a value of about US$70 000 (28). The venture is also intended to cater for tourists (170). SOURCE OF ANIMALS The original stock of 650 crocodiles was trapped along the Tana River in a three-month exercise (28). Crocodiles were reported to be being trapped from Garsen to Wenje in 1984 (124). The company holds a licence from the Ministry of Environment and Natural Resources to collect eggs, and has a monopoly in this respect (153). HUSBANDRY The animals are kept in concrete ponds, surrounded by wire mesh. Some adult animals were present in 1984 in addition to 400-500 juveniles of about 40 cm length (170). BREEDING About 250-300 eggs are believed to have hatched in 1984 (43). 102 MADAGASCAR Only one crocodile farm is known to exist in Madagascar. This was the first farm to have been registered with the CITES Secretariat as a recognised captive-breeding operation. NAME OF OPERATION Elévage de crocodiles d'"Antsobolo" Antsobolo Ampanotokana Ambohidratrimo Madagascar. Director: M. Charles A. De Lanessan. This farm has also been referred to as the "Mahitsy Crocodile Farm". DATE OF ESTABLISHMENT The farm was set up in 1969 and started commercial production in 1974. SPECIES AND NUMBERS Crocodylus niloticus In April 1983 the farm held a total of 454 crocodiles divided by size as follows:- Over 2.5m 5 1.5-2.0 m 52 1.0-1.5 m 116 0.7-1.0 m 124 Less than 0.7 m 157 (50) PRODUCTION AND TRADE Crocodiles are killed at about 3.5 years of age. About half the skins are tanned in Madagascar for use in the manufacture of goods. The remainder are used for taxidermy. None is reported to be exported (14), however the Madagascar CITES annual reports list the export of 4, 20 and 29 skins of captive-bred C. niloticus for the years 1981, 1982 and 1983 respectively. The small quantities involved suggest that these may have been trade samples. In 1985 live crocodiles were supplied to a new farm in Mauritius (164). SOURCE OF ANIMALS The original stock was taken from the wild in the form of young animals less than one year old. These have been raised to form a captive breeding stock. In 1980 the capture of wild animals ceased (50). BREEDING It took about 10 years to produce the first captive-bred generation in 1980 (72). About one hundred juveniles are now hatched on the farm each year and it is hoped that this figure will improve as the breeding stock continues to mature (50). Breeding since 1980: 1980 39 from 1 female 1981 109 from 8 females 1982 76 from 2 females (72) HUSBANDRY Total area 1300 m2. This includes 700 m2 of ponds, and 600 m2 of open space divided into 8 enclosed areas of pond and open land (72). Gravid females are separated from the rest and the eggs are collected. They are then put in another pen, with sand banks, to hatch (14). 103 Madagascar The hatchlings are fed on frogs and insects. Dog meat, which is readily available locally, is the main food for adults. Feeding has been reduced from three times a week to twice a week to reduce sickness and diarrhoea (14). Water supply is from a permanent creek. The temperature is low owing to the high altitude, and so the water is allowed to flow over an area of flat concrete to warm it up, apparently by as much as 10°C, During the winter the crocodiles hibernate in tunnels in the earth side of each pen for up to four months (14). FINANCES The operation is self-financing from the sale of skins (72). RESEARCH AND PUBLICATIONS General research into improvement of the operation is carried out by the Director, Charles De Lanessan. OTHER INFORMATION National legislation forbids the export of skins unless they are from captive-bred animals (72). 104 MALAWI A proposal submitted to CITES in 1985 suggested that controlled hunting of Crocodylus niloticus in Malawi was preferable to a ranching scheme, however one pilot project was reported to be in existence (30). This crocodile farm was started at Mangochi in 1981, but it has not so far obtained a licence to trade (43). Mr Khalid Hassan was reported to be trapping crocodiles in 1984 on the Shire River for a proposed farm on Lake Malawi (183). 105 MALAYSIA There are believed to be 7 crocodile farms in Peninsular Malaysia, one in Sabah and about three or four in Sarawak. The native Crocodylus porosus population is thought to be essentially extinct in the peninsula (112). Peninsular Malaysia The Government Department of Wildlife and National Parks supplied the following information about farms keeping Crocodylus_ porosus; stocks of Crocodylus porosus held in 1984 are indicated. The first of these farms is the only one which may be undertaking breeding. Tomistoma schlegelii are not used commercially.

One rearing farm (see below), located just outside Sandakan, Sabah has been rearing C. porosus for export since about 1970 (14). Following a_ survey a crocodiles in Sabah in 1984, Whitaker (200) recommended the establishment of an exploitation project including a Government research farm at Sepilok, encouragement of private investment to develop large commercial farms, and initiation of an egg-collection project involving local people. NAME OF OPERATION Chai mei Hwa Crocodile Farms P.O. Box 633 Sandakan Sabah. Owner: Chai Yau Look. DATE OF ESTABLISHMENT About 1970 SPECIES AND NUMBERS C. porosus: 1035 individuals in 1984 (7). These included 6 adults and a further 40 which would mature within the next few years (200). PRODUCTION AND TRADE The crocodiles are reared for their skins and for meat which is marketed locally (7). Since 1978 skins have been sold to a dealer, Mr Tan, for export to Singapore and Japan. Meat is also exported to Hong Kong (14). A total of about 2000 skins have been cropped in the last 15 years, 30% of which were males and 70% females. Since the Government ban on collection of animals from the wild, all cropping has ceased and the stock is being saved for breeding (200). SOURCE OF ANIMALS The original crocodiles were wild-caught but this is now illegal Wie BREEDING In 1984 the crocodiles had not yet bred, but a breeding programme had been initiated with a 30-m diameter pen containing four females and two males (200). HUSBANDRY The crocodiles are kept in an enclosure with an area of 1000 f£t2 (93 m2) containing a natural pond. The pool has a maximum depth of 15 £t (4.6 m) and is 30-40 ft (9-12 m) in diameter. In 1978 an unknown epidemic killed over 200 crocodiles, mostly juveniles (14). OTHER INFORMATION The owner informed Mr Andau that young crocodiles are smuggled in from Kalimantan, Indonesia (7). 107 Malaysia Sarawak Rearing farms exist which raise wild C. porosus hatchlings. About 10 Tomistoma schlegelii are also thought to be present in the farms, the skins of which will probably eventually be sent to Singapore (89). There are reported to be three or four farms run by families in the area (117). Two operations are described: NAME OF OPERATION ? Crocodile Farm Pedada Road Sarawak. Operated by the Wong family. SPECIES AND NUMBERS C. porosus: over 100 are kept (117). PRODUCTION AND TRADE The crocodiles are raised for skins and meat. Skins are sold to a merchant in Singapore to be made into handbags belts and shoes. Meat is sold locally, and is considered a delicacy in the area (117). SOURCE OF ANIMALS Animals are obtained from local fishermen (117). HUSBANDRY The crocodiles are raised to a length of around 4m on a diet of pig livers, intestines and chicken meat (117). ssa *%e==%ae==%=== NAME OF OPERATION Owner: “Johnson" Jong Joon Song P.O. Box 670 Kuching Sarawak. SPECIES AND NUMBERS C. porosus: 100 hatchlings and 600 "full-grown" animals (207). PRODUCTION AND TRADE Skins are sold to Hong Kong and Europe. SOURCE OF ANIMALS It was hoped that increased breeding success in 1985 would obviate the need to purchase crocodiles (207). HUSBANDRY The main breeding pen is 100 ft long (30 m) and contains 50 adults (200). The hatchlings are fed on prawns. There are at least three farmhands (207). BREEDING Breeding has been achieved since 1981, a total of 21 nests having been laid from 1980-83. In 1983 7 females laid eggs but only two clutches produced young. Considerable effort has been directed towards developing breeding and incubation techniques and careful records are kept of reproductive data (200). Initially the hatching success was low, in the region of 20%, but this increased to 85% in 1983 (207). FINANCES Annual expenditure is in the region of M$80 000 and the farm is still running at a loss (207). 108 MALI A private company named Mali Reptiles plans to operate a crocodile farm near Bamako, in Mali, involving Crocodylus niloticus but the farm had not reached commercial status in 1983. A small pilot-scale farm has been operated since 1979 with 34 C. niloticus captured from Ségou. The erocodiles are held in ponds with feeding installations and provision for cleaning the water. Research carried out since 1980, with FAO co-operation, has shown the project to be viable. Projected production is between 1000 and 3000 skins by 1986. The farm is financed by a private grant of MF90 000 000 put up by European partners (159). 109 MAURITIUS The first crocodile farm started operation in Mauritius in 1985. NAME OF OPERATION Bioculture (Mauritius) Ltd Senneville Riviére des Anguilles Mauritius. Owner: Mr Owen Griffiths.

SOURCE OF ANIMALS The original stock was obtained on 7 February 1985 from the Mahitsy Crocodile Farm in Madagascar (164). HUSBANDRY The original capacity of the farm in 1985 was for 250 animals, but it was hoped to increase this to 2000 (164). 110 MEXICO There are two Government departments in Mexico which are involved in the setting up of crocodilian farms, the Secretaria de Pesca and the Secretaria de Desarrollo Urbano y Ecologia (SEDUE). Between them they operate a total of seven breeding centres, with others planned. There is one farm operated by the Instituto Nacional de Investigaciones Sobre Recursos Bioticos (INIREB) and two private farms. So far as is known, none of the farms is yet producing skins commercially, although this is clearly the ultimate intention. The Secretaria de Pesca generally only involves itself in commercially related ventures. A farm in Chiapas, the original funding for which was partially provided by the World Wildlife Fund, was forced to close because of oil pollution (118). The Direccion General de Flora y Fauna Silvestre, a division of SEDUE, has also expressed an interest in starting a farm for Crocodylus acutus in Quintana Roo and for Crocodylus moreletii in Yucatan (118). It was reported that the Mexican Government had established farms for Crocodylus moreletii in Veracruz (22), but Lazcano-Barrero (118) doubts that farms have ever existed in that state. NAME OF OPERATION Municipio de Acapetahua Chiapas. Operated by: Secretaria de Pesca. SPECIES AND NUMBERS — Crocodylus moreletii (95).

This farm was still operating on a small scale in 1984 (31). A proposal was submitted to develop a ranch at Mungari Camp, Marromeu, utilizing waste meat and offal from mammal culling operations in the Zambezi Wildlife Utilization Area which totals 2.5 ta month, and should be sufficient for 2000 animals. A second ranch at Cubo village, Messingir, was proposed initially with 200 animals, but building up to 2000. This would utilize waste from the Tilapia and Clarias fishery in Messingir Reservoir (196). Captive-breeding Operations for certain birds, reptiles and frogs were also being considered (175). The ranching programme was still in the proposal phase in 1984, only one crocodile rearing station being reported at that time (31). The farm, EMOFAUNA Crocodile Farm, had 32 three-year-old crocodiles and had not collected any eggs in 1984. Previously the farm had held up to 800 crocodiles, and future expansion was still planned (176). 115 NEPAL There are no commercial crocodilian farms in Nepal, but there is a large breeding centre for gharial in the Royal Chitwan National Park. NAME OF OPERATION Gharial Breeding Farm Royal Chitwan National Park Kasara, Chitwan Nepal. Senior Warden: T.M. Maskey DATE OF ESTABLISHMENT 1979 SPECIES AND NUMBERS Gavialis gangeticus: 255 animals in 1983 (125). PRODUCTION AND TRADE The Gharial Breeding Farm is not at present a commercial operation, however future commerce does not appear to have been ruled out. Production of G. gangeticus for release to the wild can be summarised thus: Year Place of release Age Number 1981 Narayani River 3 yrs 50 1982 Narayani River 3 yrs 50 1983 Narayani River 3 yrs 50 1983 Koshi River 3 yrs 42 (125) All of the animals released are tagged and some have been fitted with radio telemetry collars to allow monitoring (89). SOURCE OF ANIMALS All of the animals have been obtained from the wild. The eggs are collected within Nepal. Number of eggs obtained 1979-81 1979 543 1980 350 1981 150 (125) BREEDING The animals do breed at the farm, however the main source of animals is from the hatching of wild-obtained eggs. A hatch rate of approximately 50% has been achieved. Number of eggs hatched and survival of hatchlings, 1979-81 Year Number hatched Number survived 30 days 1979 294 200 683 1980 187 140 75% 1981 64 30 46% (125) HUSBANDRY For the first year hatchlings are kept in the hatchling pools of size 2m x 2m x 0.5 m. They are next moved to the yearling pool of size 4m x 4m x 1m. The pools are concrete and have a running water supply. The animals are fed daily on locally available fish (125). 116 Nepal FINANCES The sponsors for the operation are His Majesty's Government of Nepal, the Frankfurt Zoological Society and the Smithsonian Institution.

It was estimated that there were a total of 250 captive G. gangeticus and 10 captive C. palustris in Nepal in 1982 (197). a7 PAKISTAN Interest in a crocodile conservation/management programme was expressed (201), and a Government plan to breed crocodiles and gharials in the Punjab and Sind was being considered for 1984 (163). In 1979 Mr S. Aftab Alam acting for IGUANA (2), a leather company of Pakistan, stated that the company intended to set up a commercial breeding programme involving Crocodylus palustris and Gavialis gangeticus, and that advice had been sought from WWF headquarters. The farm was planned to follow the pattern of Samutprakan, Thailand, but would not be started until a similar project, of greater priority to the company, involving Varanus griseus (desert monitor) had been established (3). Address: IGUANA (Manufacturers of Reptile Skins and Leather Goods, Suede Wear and Footwear) Noor Estate Main Drigh Road Karachi 8 PAKISTAN The Ministry of Food, Agriculture and Co-operatives stated, in 1983, that IGUANA had not implemented their pian to breed Varanus and were unlikely to start breeding crocodiles (163). The estimated total number of captive C. palustris in Pakistan in 1982 was 50 (197). 118 PAPUA NEW GUINEA Most of the information in the Papua New Guinea section of this report was provided by Martin Hollands. In the mid-1960s the Government of Papua New Guinea became concerned about the future of the crocodile industry in the country. In only two decades, unrestricted skin hunting had reduced the readily accessible populations to the extent that the harvests of both Crocodylus _porosus and Crocodylus novaeguineae had tailed off dramatically. Further indications about the state of the industry came from the size of skins exported; despite there being a marked preference for large skins the average size exported was down to below 8 inches (203 mm) in belly width. This concern led to the introduction of the Crocodile Trade Protection Act (1966), which set a maximum size on skins which could be traded, in an attempt to protect the remaining breeding stock. The Government's Wildlife Division also adopted a National Policy on Crocodile Farming, to try and substantially increase the potential revenue to the rural people from a _ sustained-yield management programme. This would be done by cropping at the readily-replaced hatchling level, with captive rearing of these to a commercially acceptable size. It was envisaged that the killing of wild crocodiles for their skins would slowly be replaced by the establishment of hundreds of small village crocodile ranches. Although the implementation of a ranching network, if somewhat different from that originally proposed, is progressing well, with nearly 30 000 crocodiles now on ranches, it will be a number of years before ranched skins comprise the bulk of the trade of Papua New Guinea. However the harvesting of both skins and live crocodiles is now conducted in a controlled manner, with a monitoring programme to assess its impact. During the 1970s and early 1980s Papua New Guinea had been exporting a sustainable annual harvest of 15 000-35 000 Cc. novaeguineae skins, and 7 000-11 000 C. porosus skins. This earns the country approximately US$2 million a year. Papua New Guinea now has a diverse, and somewhat confusing, range of crocodile ranching operations. These range from small village pens, which might never hold more than 25 animals, to large commercial ranches with up to 15 000 which are still expanding. To appreciate the reasons for these, and to understand their respective roles it is necessary briefly to review the development of crocodile ranching in Papua New Guinea. The original concept was that ranching would be on a village level. Virtually every village in crocodile areas would have a small, "bush material" pen, and feed a hundred or so crocodiles on fish. To encourage the development of these village operations the Government built a number of demonstration ranches in appropriate areas of the country. These would be used as models for village ranches, and as bases for extension work on crocodile husbandry, pen construction, skinning and skin treatment. Realizing the enormity of the task the Government requested, and received advice from the IUCN SSC Crocodile Specialist Group, and considerable assistance from the United Nations. Between 1975 and 1979 considerable effort was put into the Village ranching programme. At its peak there were approximately 200 Village ranches operating, with a total stock of 8000 animals. However it soon became apparent that locating the rearing operations in the 119 Papua New Guinea crocodile swamp areas had numerous problems, particularly ensuring a year round food supply, and siting the pens so that water is available in the dry season, without flooding in the wet season. It was realized that if village people were to be encouraged to keep crocodiles it would be necessary to develop a back-up rearing system, to which villagers could readily sell their animals when necessary. The opening of two large-scale commercial operations was therefore encouraged for development as the final rearing point for surplus village stock. These ranches were set up to utilise the large volume of cheap feed available as waste from the country's main poultry operations. Their location and available funding would allow many management’ and husbandry problems encountered in village operations to be overcome. It was therefore essential to develop a live-purchase system capable of safely moving large numbers of small live crocodiles from villages to these commercial ranches. The basis of this network was to be the Government demonstration ranches, already built in the right places. These ranches took on the extra duties of acting as collection centres, and extensive patrols gave the village people the chance to sell stock they did not wish to rear themselves. By Government control of the price system it was ensured that prices of live animals were kept high enough to encourage hunters to spend their time trying to catch livestock instead of just skins. These Government ranches would continue buying stock until they had 300-400 crocodiles between about 50 and 90 cm total length. Representatives of one of the commercial ranches would then fly in a light aircraft to collect these. Specially designed cardboard tubes and boxes allowed the efficient loading of the animals, and their transport with extremely low mortality. A number of private ranches also started selling direct to the commercial ranches. Some of these existed solely by catching and selling stock; others rear some stock and sell off any surplus. As feed is a greater constraint than crocodile availability, in virtually all places a “combined operations" ranch is the ideal. All live crocodiles brought in to these by outsiders can be purchased, hence helping the intended shift to ranching; those not too big to be kept on the available food are reared to culling size, any surplus is sold to the large commercial ranches. The Government is actively encouraging the development of these "midi-ranches" at abattoirs and fish plants throughout the country. The two already established at such localities are running very successfully; other operations in this category run well on locally-caught fish. The details of the operations, included at the end of this section, only cover ranches involved in rearing; village ranches are not detailed, and operations which only sell live crocodiles are excluded. Skins both from ranches and the wild are sold through licensed exporters, and all shipments are checked and tagged by Government inspectors. Other crocodile products may only be sold by commercial ranches (97). The total number of crocodile skins exported from Papua New Guinea since 1976 from both wild harvest and farms is shown in the following table. In 1983 farm production was running at about 10% of the wild harvest but this seemed set to rise in the following two years. C. porosus comprised 18% of all wild-caught crocodiles but 29% of all skins exported from farms. This reflects the fact that it is 120 Papua New Guinea preferentially kept on farms as it has a higher-value skin and it is easier to keep. Crocodile skins exported from Papua New Guinea from 1976 onwards.

In 1983 the corresponding figures were France 37%, Japan 62% and Singapore 0.5%. The Crocodile Trade (Protection) Act 1974 established very firm controls over crocodile exploitation. Only citizens of Papua New Guinea may hunt or kill crocodiles, and licences are needed to trade in them. Traders must have lived in the country for at least two years and may only trade within a specified area. A separate licence is needed to export skins. Additional regulations were introduced in 1981 to control farms and the sizes of crocodiles exploited. No crocodile with a belly width greater than 510 mm may be traded or kept on farms, and crocodiles of less than 180 mm belly width may only be traded live for the purpose of stocking farms. Crocodile farms with more than 200 animals must acquire a licence, the conditions of which include completing 6-monthly stock returns and notifying the authorities of the outbreak of any disease (137). The following summary details the numbers of live crocodiles taken onto ranches from the wild (97).

Rather than location being determined by crocodile distribution, the ranches are located where there is a plentiful supply of cheap food. The two already operating are in association with the countries two largest poultry operations, one in Port Moresby and one in Lae. Details of pen design, husbandry, feed consumption, mortality and growth rates are in Melvin Bolton's "Crocodile Husbandry in Papua New Guinea", available from the Crocodile Project, Box 2141 Boroko, Papua New Guinea. These ranches have now been granted permission to start breeding programmes, and it is probable that the considerably easier supervision of such large, centralised operations will allow them to be granted special dispensations on the size of skins they can market; they are already permitted to sell by-products, both domestically and for export (97). NAME OF OPERATION Mainland Reptiles P.O. Box 196 Lae Morobe Province. Operated by: Mainland Holdings Pty. Ltd DATE OF ESTABLISHMENT Approved and established in August 1979. SPECIES AND NUMBERS 11 250 C. novaeguineae 3 750 C. porosus (97). The total stock in March 1983 was 14 000 animals (78). By early 1984 the number had risen to 15 000 (97). PRODUCTION AND TRADE Production is primarily aimed at skins but meat and other by-products which may have a commercial value are being examined (97). The meat cannot be sold locally as a Government licence is needed to buy or own any crocodile, or part thereof. Crocodile meat in a dried form is worth around S$23 kg-1! in Singapore, but as a 30-kg crocodile yields only around 2 kg of dried meat this means crocodile meat is of little economic significance to the ranch. The managers are investigating the commercial possibilities of producing crocodile oil for the perfume industry (84).

These are artificially inflated as few animals were slaughtered in 1983 owing to the low price of skins (85). 122 Papua New Guinea SOURCE OF ANIMALS Stock is mainly obtained from village type holding farms in the Sepik River area of north-east Papua New Guinea. These farms catch small crocodiles from the wild which are then transported by aeroplane to Lae. Mainland Holdings stated in 1983 that they prefer animals between 0.5 m and 1.0 m in length as these are easily transportable and have a lower mortality rate once introduced to the farm than smaller animals; 7% rather than 25%. Prices paid for these animals are estimated on a Sliding scale according to size, the highest price being paid for the 1.0-m animals. No extra is paid for animals over this size. In 1983 surplus stock was also taken from other farms (84).

Breeding stock has been selected from animals reared on the farm and it is hoped to have 300 breeding females by the end of 1985. Breeding had not taken place by August 1983 (84). A breeding licence was granted in 1983. The Government have also loaned the operation 28 C. porosus adults as breeding stock. Selected rearing stock of C. porosus will also be kept as breeders (97). HUSBANDRY The farm has at its disposal an area approximately 0.75 km2. Stock is held in ponds and divided by size of animals. The animals are fed on chicken offal from the adjoining poultry farm. At present total food consumption by stock is about 10 t a week. Breeding stock is to be kept in natural-type earth ponds with an initial male to female ratio of 1:1. The entire stock is counted once every year, each animal being Measured and its condition examined (84). Overall natural farm mortality averages 4.5% a year (97). FINANCES The crocodile farm is run in conjunction with a large commercial chicken farm. It is therefore not always possible to separate the costs of the two enterprises adequately; however it is considered to be a fully self-financing commercial venture. RESEARCH AND PUBLICATIONS A four-year study of growth and feeding trials is being carried out and the results are to be published. Research on the growth and feeding of crocodiles has been carried Out by Mark Rose (84). 123 Papua New Guinea NAME OF OPERATION Ilimo Farm P.O. Box 1885 Boroko Port Moresby N.C.D. DATE OF ESTABLISHMENT 1979 SPECIES AND NUMBERS In 1979 2423 animals were held on the farm (2). By early 1984 this total was 5000: 3000 C. novaeguineae and 2000 C. porosus (97). PRODUCTION AND TRADE Production is mainly of skins but also of meat, gall-bladders and penes. Production of other by-products is being considered (97). SOURCE OF ANIMALS All stock originates from wild-caught hatchlings (97) and has been almost entirely supplied, at Government-controlled prices, through the Government buying and redistribution schemes (115). BREEDING In 1983 a breeding licence was approved, and an initial breeding colony of 17 females and 7 males was loaned by the Government. Selected rearing stock will be kept for breeding (97). HUSBANDRY The farm is associated with the poultry industry and therefore has an assured supply of minced and chopped chicken offal from the local processing plant (97).

The operation was a Government demonstration farm but is currently run by the Department of National Parks as an educational/public display facility and for research by the Crocodile Management Project (97). DATE OF ESTABLISHMENT Early 1970s SPECIES AND NUMBERS C. novaeguineae - adults and C. porosus - adults. In 1979 a total of 1150 crocodiles were held on the farm (194). PRODUCTION AND TRADE The farm produced skins until 1982. There is no longer any commercial production from the farm (97). SOURCE OF ANIMALS All stock was originally wild-caught. There is no input of animals now (97). BREEDING Both C. novaeguineae and C. porosus were bred and reared at the farm experimentally with the aim of improving rearing standards at the Village level (194). OTHER INFORMATION A number of C. porosus reared at Moitaka were used for re-stocking depleted wild stocks in Gulf Province. By January 1981, 43 C. porosus from Moitaka had been released in Gulf Province for this purpose (59). 127 Papua New Guinea NAME OF OPERATION Pagwi Crocodile Farm Pagwi East Sepik Province.

HUSBANDRY The food is obtained from a local abbatoir (97). 128 PHILIPPINES At present there is one conservation-orientated operation breeding crocodiles in the Philippines, but no authenticated commercial farms. There is reported to be one private farm of unknown status. A Japanese consortium has expressed interest in establishing a commercial farm. NAME OF OPERATION Crocodile Breeding Project Silliman University Marine Laboratory near Dumaguete City Negros Island. Operated by the Silliman University Environmental Centre in conjunction with the Smithsonian Institution and the World Wildlife Fund. DATE OF ESTABLISHMENT 1980 SPECIES AND NUMBERS Crocodylus novaeguineae_ mindorensis: 25 including two breeding pairs and 11 hatchlings in September 1984 (4). In 1982 the farm held an additional female C. n. mindorensis and one Crocodylus porosus (5). PRODUCTION AND TRADE The operation iS an experimental project investigating conservation techniques and the viability of commercial farming. At present there is no commercial production. SOURCE OF ANIMALS All of the crocddiles have been obtained from captive sources, including both private collections and government projects on Mindanao and Luzon Islands (20). BREEDING The first pair of adults was acquired in 1980. In 1984 a second breeding pair was obtained (5); it was hoped that they would breed in 1985 (4). One female C. n. mindorensis laid three clutches totalling 32 eggs in 1981, however no surviving offspring were produced. In 1982 10 young were produced from 33 eggs, and 7 in 1983 from 20 eggs. This represents the first known captive propagation of this subspecies (5). Breeding took place again in 1984 when 12 young were hatched from 25 eggs laid (5). By September 1984 eleven of these were still alive (4). HUSBANDRY The animals are kept in two pens. One is used as a breeding pen (15 m x 11.6 m), and has a large central oval pond (ll.l m x 3.8m x 1 m deep) with three small peripheral concrete ponds (5). The second pen is used for holding the animals; insufficient depth of water makes it unsuitable for breeding (20). A second breeding pen measuring 14.5 x 6 m with equal areas of land and water was built in 1984 (4). The crocodiles are fed on locally caught and donated bats, cats, rats, dogs, frogs and insects. The carcases of experimental animals from the University are also used when available (20). FINANCES The Silliman University Environmental Centre, Smithsonian Institution, the World Wildlife Fund and donations from government agencies finance the project (20). 129 Philippines RESEARCH AND PUBLICATIONS Areas of study include reproductive biology of the crocodile, growth in captivity, distribution and status of wild populations, feasibility of commercial crocodile farming and the use of crocodiles as an additional component of fish farming. OTHER INFORMATION The operators are looking for additional crocodiles for the breeding project. One of the objectives of the programme is to establish sanctuaries for release of captive-bred crocodiles. The farm is also being used as an educational base for crocodile conservation (20). Two three-year-old crocodiles were planned to be released in Calauit Wildlife Sanctuary in late 1984 (4). There are known to be a further 17 C. n. mindorensis in captivity in the islands of Luzon, Cebu and Negros (5). sea *%eaa*te==*% === An association of 50 Japanese companies that manufacture products made from reptile skins has obtained financial support from the Japanese Government to start a crocodile breeding project (35): NAME OF OPERATION Japan Crocodile Farming Institute in the Philippines (Palawan) DATE OF ESTABLISHMENT Proposed for 1987 (35). SPECIES AND NUMBERS C. n. mindorensis: It is intended to start initially with a stock of 150 females and 50 males (26). (As the wild population is estimated to be less than 100 (5) it is difficult to see where these would come from. ) It is hoped eventually to breed 3000 crocodiles annually (35). PRODUCTION AND TRADE The aim of the project is to conserve the near-extinct crocodile population in the area, eventually to re-introduce it to suitable areas to produce a sustainable yield of crocodile products. The Institute intends to train project personnel and local residents in crocodile-farming techniques. The 6-year project is being jointly negotiated between the Japanese and Philippine Governments (26). sas *ese*===% === NAME OF OPERATION Name unknown. At San Ramon, Floridablanca, Pampanga. Operated by: Mr Romeo Saldana. DATE OF ESTABLISHMENT 1981. SPECIES AND NUMBERS Crocodylus porosus: parental breeding stock of 28 animals. OTHER INFORMATION Reported in 1983 to be in initial stages (6). 130 RWANDA In 1984 the Office Rwandais du Tourisme et des Parcs Nationaux reported having given approval to a private enterprise to establish a wildlife farm utilizing crocodiles and several species of large mammals (90). A pilot project farming Crocodylus niloticus was reported to be in operation in 1984 (30). 131 SENEGAL It was reported in 1983 that there was a proposal to establish a crocodile (presumably Crocodylus niloticus) farm in Casamance and that funds were being sought (77). 132 SINGAPORE A survey of crocodile farming operations, carried out by Internationaler Reptilleder-Verband E.V. established that there were three crocodile farms in Singapore (74). However it is apparent that there are considerably more than this; many small-time farmers, who keep primarily pigs and chickens, feed the waste offal and carcases to some crocodiles (120). Many crocodile skin businesses keep or have kept young wild crocodiles in back-yard enclosures, raising them until they are about two years old. Some of these establishments kept as Many as 400 animals. The young animals were reported to be fed on a diet of shrimps and small fish until about 2 ft (60 cm) long. They were then fed on a diet of animal skins and intestines from abattoirs until they reached a length of 4 ft (121 cm) when they were killed (Singapore Trade, June 1961, fide 12). According to King et al. (112), Crocodylus porosus has been extinct as a breeding resident in Singapore for over 30 years. The large number of rearing farms flourishes in Singapore by importing eggs and young from other Asian and Pacific areas. Stock is known to have been imported from Indonesia, Malaysia, Papua New Guinea, Australia, and the Philippines. Some limited breeding is done on the farms. Output from these farms is expected to decline as surrounding stocks decline. Whitaker (200) visited two farms in 1984 and confirmed the presence of some Crocodylus novaeguineae. He asserted that "in general, claims of breeding can be discounted though an occasional nest may be produced". = Caiman crocodilus crocodilus and Crocadylus novaeguineae are both reported to be raised for both meat and skins in Singapore (65). The Operations NAME OF OPERATION Tan Moh Hong Reptile Skin and Crocodile Farm or Singapore Crocodile Farm. 782/790 Upper Serangoon Road, Singapore - 19. DATE OF ESTABLISHMENT The farm was established in 1945, and occupies a site of one acre (0.4 ha) of residential land (37). SPECIES AND NUMBERS A brochure produced by the farm shows photographs of Crocodylus porosus and Tomistoma schlegelii (37). A newspaper article mentions "sea crocodiles", “river crocodiles" and "alligators", reportedly from South-east Asia (10). Total stock approximately 600 (37). Monitor lizards and pythons are also reported to be kept (37). PRODUCTION AND TRADE The farm is an integrated operation incorporating tanning and Manufacturing facilities. Handbags, purses, wallets, belts, shoes and Other souvenir items are produced. Crocodile meat is also sold, both as a delicacy and for medicinal use. The crocodiles are slaughtered at 3-5 years old. The products are sold in a farm shop and are also exported all round the world. Some whole skins are exported to F.R. Germany, France, Japan and other countries (37). Some of the skins processed on the farm are imported (10). 133 Singapore In promotional literature the farm states that "sea crocs offer the best skins. A handbag with the familiar sea croc markings of small scales can cost as much as S$850, and river crocodile is next down the 'scale', oddly because the scales are larger. Then comes’ the alligator." The farm sells belts from S$15 to S$95, and small alligator wallets from S$24. (10) The farm receives 300-400 visitors a day (37). SOURCE OF ANIMALS Some young reptiles are imported from Asian countries while most are "bred locally” (37). HUSBANDRY The crocodiles are kept in large concrete pools (10). The juveniles are fed on prawns and mussels while the older animals eat pigs' lungs and fish (37). The farm is linked to a country farm outside Singapore where some 250 crocodiles are kept (10). === * ===% ===%* === NAME OF OPERATION Singapore Crocodilarium Pte Ltd 730 East Coast Parkway.

It is open to the tourists for exhibition of the live animals and for sale of crocodilian skin products (102). Depending on the success of the breeding programme, further similar farms may also be set up (174). : NAME OF OPERATION 544-C Lim Chu Kang Road, Singapore (2470). Owner: Mr Eng Gee Seng, DATE OF ESTABLISHMENT About 1975 (150) SPECIES AND NUMBERS The total stock was over 1800 in 1985. A photograph shows some Crocodylus porosus (150). PRODUCTION AND TRADE Skins are sold to local manufacturers of leather goods. The price was reported to be between S$100 and S$600 each (150). 134 Singapore SOURCE OF ANIMALS The initial stock of 80 animals was obtained from Indonesia. In 1985 the farm was receiving about 50 young animals a month from Indonesia (150). BREEDING No breeding had taken place prior to 1985, but it was under consideration (150). HUSBANDRY The crocodiles are fed on chicken or pig offal, fish, prawns and cockles (150). OTHER INFORMATION The farm also has about 600 pigs, some ducks and chickens (150). It is in an area where the Government has announced the intention of phasing out pig farms (120). NAME OF OPERATION Track 13 Punggol Road Singapore (1954). Owner: Mr Yang. DATE OF ESTABLISHMENT The farm was reported to be operating in 1980 (15). SPECIES AND NUMBERS = The total stock was about 1000 in 1980. A photograph shows some Crocodylus porosus (15). PRODUCTION AND TRADE Skins were sold to local tanners about twice a year. Total annual production was about 400 in 1980 (15). SOURCE OF ANIMALS Animals were obtained from Indonesia (15). HUSBANDRY The crocodiles were kept in 16 enclosures (15). OTHER INFORMATION The farm also had about 30 000 poultry (15). A fifth farm is reported to exist in Singapore which is operated by Leah Liang Joo. The farm started in 1970 with 60 crocodiles. By 1976 the stock had increased in size to 3000. Most of the crocodiles are probably C. porosus although some are reported to have been obtained from South America (208). 135 SOUTH AFRICA The first crocodile farm in South Africa was established in 1968 outside Pretoria and has bred crocodiles regularly since 1970. From 1977 onwards several more farms were established around the country, and in 1983 formed themselves into the South African Crocodile Farmers’ Association. In 1984 there were at least 12 farms with a total stock of about 2200 C. niloticus, mostly juveniles obtained from farms in Zimbabwe and South Africa. Breeding is planned at all farms but by 1983 had only occurred at three. The wild population of crocodiles in South Africa is very low, and to survive indefinitely all farms must therefore operate on a closed cycle. Many of the farms obtain income from tourists and the sale of livestock but none, except the original farm, anticipates being able to sell skins until at least 1988. It is not clear whether the latter has yet done so. Cape Province NAME OF OPERATION Cango Crocodile Ranch Pty Ltd Private Box 559 Oudtshoorn 6620. Director: P.H.S. Arnold. DATE OF ESTABLISHMENT The farm was established in 1977 and since that date has acted as a tourist interpretative centre but is not yet of commercial standing. SPECIES AND NUMBERS Crocodylus niloticus: stock totals over 200 animals (39). PRODUCTION AND TRADE In 1983 it was thought unlikely that this farm and others which belong to the South African Crocodile Farmers' Association would be able to produce skins before 1988 (38). SOURCE OF ANIMALS The farm was established in 1977 with a stock of 120 animals. One of these was an adult male supplied by the then Rhodesian Parks Board and the rest were reared from wild-taken eggs supplied by Spencer's Creek Crocodile Farm, Victoria Falls, Zimbabwe. In 1978 a further five wild-caught animals were obtained from the Rhodesian Parks Board. In 1979 60 ranched hatchlings were obtained from Sengwa Mouth Crocodile Ranch, Zimbabwe (39). All stock obtained since then has been purchased from the Natal Parks Board in the form of captive-bred juveniles of wild-caught parentage, totalling 50 animals in 1981 and 100 in 1982 (38). BREEDING In 1981 6 crocodiles were bred on the farm and in 1982 13 were bred. HUSBANDRY Hatchling crocodiles are kept in tiled ‘environmental tanks' which are temperature-controlled. Older/adult animals are kept in open air enclosures, half land, half water, which have heated retreats for the crocodiles. The diet consists of liver, offal, and ostrich by-products. FINANCES The operation is self-financing. Some income is obtained from tourists (39). 136 South Africa NAME OF OPERATION Glenashby Crocodile Ranch Glenashby P. Bag X 513 East London Cape Province.

Crocodylus cataphractus: 2 males, 1 female (54). In mid-1983 the Centre had 9 female, 2 male and 6 juvenile c. niloticus (148). PRODUCTION AND TRADE Over 400 live animals have been produced for sale to crocodile farmers, at R20 each (148). OTHER INFORMATION St Lucia Crocodile Centre caters mainly for tourists, and is orientated towards public education on crocodiles. It has a small museum, a shop, aquaria and some live crocodiles. Hatchling crocodiles are produced for restocking purposes and also for sale to crocodile farmers. The Centre has a research role with a brief to monitor crocodile farming in Natal, and also to carry out investigations and produce recommendations on crocodile populations with special reference to Lake St Lucia. It has also functioned as an IUCN/SSC Crocodilian Specialist Group breeding bank since 1975 (54). saa *%ae=%===% === NAME OF OPERATION River Bend Crocodile Farm P.O. Box 245 Ramsgate 4285 Natal. Director: N.H. Kelly. DATE OF ESTABLISHMENT October 1981 SPECIES AND NUMBERS C. niloticus: total stock 117 animals in 1983 (111). PRODUCTION AND TRADE No products had been marketed by 1983 but it was planned that stock would be killed for their skins from 1987 onwards. Live animals have been provided to two parks (111). SOURCE OF ANIMALS Animals have been obtained from crocodile ranches in Zimbabwe and from crocodile farms in South Africa (148). Stock has been obtained as follows (111): Year Adults Juveniles 1981 0 70 1982 2 0 1983 1 44 139 South Africa BREEDING A breeding programme is planned and it was hoped that stock would first produce eggs in the 1983/1984 breeding season (111). HUSBANDRY The farm has large open breeding pools with five different levels varying from 2 m to 2 cm deep and stocked with two species of fish. Sand nesting areas are provided as well as shade, lawned area and cement basking area. Indoor accommodation has under-floor and ceiling heating and solar-heated water is provided for crocodiles under 1.5 m. The stock is fed on fish and chicken; the animals kept outside are fed one whole chicken rolled in bone meal each week (111). FINANCES The farm is self-financing, depending on tourists for income. OTHER INFORMATION Educational slide shows are offered to the public on open days. The farm is a member of the South African Crocodile Farmers’ Association. (111). NAME OF OPERATION Crocworld Crookes Brothers Ltd P.O. Renishaw South Coast Natal, 4181. Manager: A.C. Pooley. DATE OF ESTABLISHMENT January 1984. SPECIES AND NUMBERS C. niloticus: a permit is held for keeping a total stock of 8500 crocodiles (149). PRODUCTION AND TRADE It is envisaged that the first hides will be available for sale in 1987/88. Income will also be derived from a tourist complex (149). SOURCE OF ANIMALS A permit has been granted to obtain 72 adult crocodiles (60 females and 12 males) from Malawi during 1984. It was hoped to purchase 1500 hatchlings from commercial farms in Zimbabwe. Thereafter the farm will be self-supporting (149). BREEDING A breeding programme is planned. HUSBANDRY The farm has four controlled-environment buildings to house up to 2000 hatchlings for the first year of life. The buildings are designed to take advantage of winter sunshine, and are air-conditioned for the hot summer weather. From one year until slaughter at about 3.5 years the crocodiles will be kept in open stock ponds where they will be regularly graded. Breeding ponds are laid out in areas of natural bush with viewing paths and walkways for visitors. There is an incubation room with capacity for 5000 eggs under controlled temperature and humidity. A cool store has been built to contain up to 40 tons of food (149). 140 South Africa OTHER INFORMATION Tourism will be an important aspect of the farm. A scenic drive has been built from the main coast road and there will be a large restaurant with a playground and curio shops; this complex should be open by the end of 1984. Educational facilities are planned with a lecture room and nature trails. There will also be wildlife exhibits, possibly including some exotics. In the longer term, fish farming is being considered, using the effluent from the rearing ponds for catfish (Clarias spp.) and Tilapia spp. The fish will eventually be fed to the crocodiles (149). === % === %===% === 141 South Africa Transvaal NAME OF OPERATION Croco Farm De Wildt near Pretoria, Transvaal. Postal address: P.O. Box 18100, Hercules, 0030 Pretoria. Director: Jan-Gerd Kuhlmann. DATE OF ESTABLISHMENT Project started privately in 1968 (114); became commercial in 1978. SPECIES AND NUMBERS C. niloticus: Total stock about 600-700 animals (182). PRODUCTION AND TRADE The purpose of the farm is to provide crocodiles for restocking into game reserves, as well as for commercial use (114). Although some reports indicate that crocodiles are released into South African rivers (11), there appears to have been no release to the wild so far. A 1978 report indicated the aim of the farm to produce 2000 crocodiles a year (9). Crocodile products entering trade from the farm are marked to show that they are not from wild animals (114). SOURCE OF ANIMALS The farm was established with 14 mature '‘'nuisance' crocodiles caught in the Republic of South Africa under permit from the South African Nature Conservation Division. This is the only stock gained from the wild by the farm (114). It is reported that 20 unsexed two-year-old crocodiles were purchased from Binga Crocodile Farm, Zimbabwe in August 1976 (182). BREEDING All breeding has been from the original 14 crocodiles, which have been breeding in captivity since 1970. The farm is now beginning to breed third generation captive stock and is said to be a closed-cycle operation (114). HUSBANDRY The farm covers 20 ha (145). Breeding crocodiles are kept in landscaped concrete pools; eggs are hatched in incubators; hatchlings are kept in nurseries under controlled conditions; and young crocodiles are kept in hot-houses until they are ready for marketing (114). : FINANCES | The farm is privately financed by Jan-Gerd Kuhlmann (114). saa *%e==%===%=== NAME OF OPERATION Sabie Crocodile Farm P.O.

SPECIES AND NUMBERS C. niloticus: in April 1983 stock totalled 444 animals, 12 adults, 394 juveniles and 38 animals under one year old. 142 South Africa PRODUCTION AND TRADE The operation was not producing commercially in 1983. Production will be based on skins. Skins produced on the farm will be marked to indicate that they are from farmed animals. SOURCE OF ANIMALS Two animals were obtained under permit from the Kruger National Park, onto which the farm borders, in March 1981. Stock has been obtained from the Natal Parks Board, the Cango Crocodile Ranch and Kariba Crocodile Farm in Zimbabwe as follows: Year Adults Juveniles 1981 8 144 1982 4 250 BREEDING In the 1982/1983 breeding season 38 animals were bred on the farm. HUSBANDRY The farm has earth-floored breeding pens skirted by concrete and containing natural and concrete rearing pens which are scrubbed out every 24 hours. Each pen type is surrounded by chain-link fence, has flowing water and natural shade. Further shade is provided by large cloths where necessary. The crocodiles are fed on meat provided by the culling operation in the Kruger National Park. FINANCES The farm is a commercial enterprise, run by five partners. OTHER INFORMATION The taking of wild crocodiles in South Africa is controlled by the Transvaal, Natal, Cape Province and Orange Free State Governmental Administrations. The breeding which occurred in 1982/1983 was the first captive breeding to have taken place in the Transvaal. Infertile or arrested eggs are blown and sold as curios. There are tourist facilities and a shop. The farm is situated on the main road near the Skukuza Gate of the Kruger Park, and is therefore well-placed for attracting tourists (60).

HUSBANDRY The farm has large open-air ponds, surrounded by concrete and chain-link fence in which the broodstock are kept. It is intended that eggs will be laid in the soil amongst natural vegetation surrounding the ponds. Concrete rearing pens have been constructed to house any hatchlings and there is also a new block of buildings including an incubator room and food store (168). === *%===%==>=*=== NAME OF OPERATION Lomati Estates Malelane Transvaal. Director: P.J. Schoeman. SPECIES AND NUMBERS C. niloticus: 14 breeding females 6 breeding males 200 hatchlings 20+ production stock (82). PRODUCTION AND TRADE The operation was not producing commercially in 1985. Production will be based on skins (82). SOURCE OF ANIMALS The broodstock was imported from Zimbabwe (82). BREEDING In 1984 approximately 200 hatchlings were produced from eggs laid on the farm. About 500 eggs were laid in 1985 which were expected to yield some 400 hatchlings (82). HUSBANDRY The broodstock is kept in an open pen of about 100 m by 30m containing an artificial lake with a maximum depth of 2m. Breeding cubicles are located around the perimeter wall, and are floored with clean sand. The eggs are removed within 24 h of laying and are incubated in polystyrene boxes filled with vermiculite. After hatching, the young are transferred to circular corrugated iron tanks, about 2 Mm in diameter, and kept at 30°C for about the first year of life. Later they are moved to a hothouse with a transparent roof, where they are kept in concrete pens with sloping floors. Each pen holds about 20 females which are being raised as broodstock. Water temperature is not controlled and all heating is by natural sunlight. Chicken carcases are provided as food, supplemented with vitamins and minerals (82). FINANCES It is planned to slaughter the animals at about three years old when they have reached a minimum of 30 cm belly width. Current skin prices were estimated to be R100 to R150 in 1985 (82). 145 SPAIN A company known as Iberia Enterprises Ltd. requested "as many crocodiles as could be supplied" from the Natal Parks Board, Republic of South Africa, for unspecified purposes in 1979. The request was turned down. The species involved would have been Crocodylus niloticus. The address of the company is: Iberia Enterprises Ltd Felipe Bertron y Giell 3 tda 4 Barcelona. Directors: W. Martin Schutte; Roy Bates; Carmen Cano Canalis (146). 146 SRI_ LANKA The CITES Management Authority reported in 1983 that there were no farms or ranches in Sri Lanka, although there had been several attempts to start such operations (71). The estimated total number of captive -Crocodylus palustris in Sri Lanka in 1982 was 20 (197). 147 SURINAME A caiman farm was reported to exist in Suriname in 1979 (155); however no further confirmation of this farm has been found and its continued existence must be considered as dubious: NAME OF OPERATION Crocodile Farm of Suriname, N.V. Groningen, District Saramacca. SPECIES AND NUMBERS Caiman crocodilus: numbers unknown. PRODUCTION AND TRADE Skins were reported to be being exported, most likely to France, but possibly to the Netherlands and Germany (155). SOURCE OF ANIMALS The animals on the farm were probably caught on the Coesewijne River (155). 148 TAIWAN The Taiwan Provincial Department of Agriculture and Forestry supplied the following details of crocodilian farms in Taiwan (177, 178): There are 35 farms in Taiwan, the first of which was established in W976 (177). SPECIES AND NUMBERS "South American short-mouthed caiman" (Caiman crocodilus): about 8000 "Indian sharp-mouthed crocodile" (Gavialis gangeticus): about 300 "SE Asia estuary crocodile and others" (Crocodylus porosus): about 300 CL7 7.) Fuchs (79) reported that there were some Tomistoma schlegelii on one farm, but Tsai (178) also confirmed the existence of some G. gangeticus. There are unconfirmed reports that some Alligator Mississippiensis were obtained from the USA during 1984 by Taiwanese farmers. PRODUCTION AND TRADE Annual production from all farms (US$1 = NT$39): Product Weight (kg) Value (NT$) Skins 12 500 10 million Meat 30 000 12 million Other 7 500 8 million Most of this is seld within Taiwan but some is exported to Japan and Korea (177). The meat is sold for food rather than medicinal use, except those parts of the skeleton, blood, and male genitalia which have medicinal value. The skin is processed for leather manufacture (178). BREEDING About 2000 hatchlings are produced each year on the farms. Each mature female lays about 25-45 eggs with a hatching rate of 45% (177). HUSBANDRY Ponds are usually of concrete with a soil bottom and are surrounded by brick walls. Juvenile crocodilians under 10 inches (25 cm) are fed on small fish and insects while larger animals are fed chickens and pig offal (177). === *¥ === ¥ === * === Fuchs (79) supplied the following details of a farm that he had visited: NAME OF OPERATION Taiwan Crocodile Ltd Nr. 225 Shin Chung Road Matou/Tainan 149 Taiwan SPECIES AND NUMBERS Caiman crocodilus crocodilus: a total of 5200 are kept: 4800 3 months old, 0.3 m long. 80 1.5 years old, 1.2 m long. 320 7 years old, 2.4 m long.

There are plans to establish another farm in another locality where there is readily available cheap food (176). Details of the original farm are given: NAME OF OPERATION Crocodile Farm (Tanzania) Ltd Kondo Village Kunduchi P.O. Box 4382 Dar es Salaam DATE OF ESTABLISHMENT 1981 SPECIES AND NUMBERS Crocodylus niloticus. Between 1200 and 1500 were kept (108). SOURCE OF ANIMALS Stock was obtained from the Ruvu and Rufiji Rivers, Tanzania. Prior tc April 1983 80 adults and 1400 eggs had been taken from the wild. OTHER INFORMATION The farm sought advice on its establishment from crocodile farms in India, Bangkok, Abidjan, and Spencer's Creek Crocodile Ranch, Zimbabwe (108). It was reported to have closed down in 1985 owing to a shortage of cheap food for the crocodiles (176). 151 THAILAND There is only known to be one crocodilian farm in Thailand. In 1985 this farm achieved regognition by the CITES Secretariat as an approved captive-breeding operation for Crocodylus siamensis, Crocodylus porosus and hybrids between the two. It is not yet (June 1985) an approved breeding operation for the other Appendix I species kept (Tomistoma schlegelii, Crocodylus rhombifer, Alligator sinensis).

This represents a considerable reduction from the stocks of 11 700 Crocodylus_siamensis, 8550 Crocodylus_porosus and 4100 hybrid C. siamensis x C. porosus reported earlier (173). Whitaker (203) reported 152 Thailand 170 T. schlegelii, of all sizes, in 1981. In 1982 the farm also had one Caiman latirostris and one Paleosuchus palpebrosus (173). PRODUCTION AND TRADE The crocodiles are bred for meat, skins and teeth, and are a tourist attraction. An average three-year-old CC, porosus weighs 10-18 kg. Of the average 14 kg, approximately 5-7 kg of meat is marketable (173). Crocodiles reared for skins are usually slaughtered at three years. Between 1980 and 1982 skins were produced as follows (209): Year No. of skins produced 1980 1500 1981 900 1982 200 (few were slaughtered due to low market price for skins) The marked reduction in the total stock of crocodilians from 29 000 in 1983 to 10 568 in 1984 suggests either that the earlier figure was incorrect or that substantial slaughtering or other mortality occurred during 1983 and 1984. PRODUCTION AND TRADE Sixty percent of the skins are processed and sold locally, mostly to tourists, while the other 40% are salted and shipped abroad (173). In 1974 the farm was-supplying 80% of the Thai crocodile skin trade. The skins traded are not marked to show their origin (209). Early trade used to be directed towards Europe alone, mostly France (211). Of the skins produced on the farm in 1980, 700 were sold to France and 800 to Japan, in 1981 400 to France and 500 to Japan, and in 1982 all the skins were sold to Japan (209). The meat is sold locally, mostly to restaurants as a delicacy (for US$5 kg-l); it is also used as a treatment for asthma (173). The meat is sold fresh on the local market with the surplus being dried and sold to Chinese tourists at the farm's shop. The average value of a crocodile (skin plus meat) was about US$320 in 1983. The skin business has slowed down since mid-1982. It is reported that the unprocessed skin of a three-year-old C. porosus sold for about US$250 and the skin of C. siamensis sold for about 10% less (173). A more recent report (1984) put the value of skins at US$90 each C57)! Other trade is in teeth, which can be used as an ingredient of Thai medicine (210), and in live animals to zoos (209). Whitaker et al. quote values of US$10 a kg for dried meat, US$15 for lacquered heads and US$3 for feet in Thailand (204). In 1980 only one crocodile, an albino C. porosus female, was sold to a zoo, the Glady Porter Zoo, Brownsville, Texas. No crocodiles were sold to zoos during 1981 or 1982 (210). SOURCE OF ANIMALS The operation began with 20 wild-caught C. siamensis in 1950. According to Youngprapakorn (209) no animals (presumably of C. Siamensis and C. porosus) have been taken from the wild since 1952. The C. crocodilus, C. novaeguineae, A. sinensis, C. latirostris and P. Palpebrosus were acquired through the efforts of IUCN/SSC Crocodile Specialist Group, New York Zoological Society and the first working 153 Thailand meeting of the IUCN/SSC Crocodile Specialist Group in 1971 (173). Six Cuban crocodiles have been obtained through a dealer from a zoo in Czechoslovakia (211). BREEDING In 1960 150 young were hatched; in 1970 the hatch was 3500 (12). Between 1950 and 1972 the farm's crocodile population increased at 10-15% annually (40). In 1975 the farm held a breeding herd of 1000 animals; by 1975 this had increased to 3000. In 1976 the farm reported that 5740 eggs had been laid in captivity, with a 60% hatching success (40). C. porosus, C. siamensis and C. crocodilus are regularly bred beyond second generation; T. schlegelii has bred to Fl (209). In C. porosus hatch rate is 40-50%; in C. siamensis hatch rate is 50-60%. From 10-15% of hatchlings (or up to 30% according to Leather magazine (12)) die in their first year, then mortality drops to below 5% (173).

The breeding ponds are 1.5 m deep, irregular in shape, with circulating fresh water. Fish are dumped in adjacent feeding ponds at 18.00 hours every day. These pools are cleaned out daily after feeding and any excess food is removed (173). In each breeding pool the sex ratio is one male to three females. Crocodiles are fed on waste fish, but if the supply is inadequate it is supplemented with chicken wings, legs and necks. The young do not feed for the first 7-10 days but are then fed coarsely-chopped fish until large enough to be fed on whole fish (173). Around the breeding ponds are 150 roofless nesting stalls, each with a drainage ditch and each approximately 4 x 4 m with a 60 x 60 cm door facing the pool. Nesting material (dried grass and _ other Vegetation) is provided for both C. siamensis and C. porosus, by placing it in the stalls. Once the eggs are laid, the females are chased out of the pens and all further care is carried out by the farm 135 Thailand staff. The nest temperature is checked at regular intervals each day and steps are taken to keep the temperature at 95-98°F (35-37°C). The humidity is also monitored and kept as constant as possible. Upon hatching, the young are placed in a concrete nursery pool 30 m x 2m for 7-10 days. As the young animals grow they are moved to successively larger tanks but are always kept in crowded conditions with others of the same age (173). FINANCES The farm was opened to the public in 1969 and by 1971 was receiving 3000 visitors a week at a cost of 30¢ each adult, 15¢ each child, and $1 for foreign tourists. The farm now receives about one million visitors annually. Income also accrues from a gift shop, refreshment stands, elephant rides, photographers with tame pythons, stands selling fish to feed the crocodiles and assorted amusements. Some of the first-year hatchlings that die naturally are stuffed and sold as souvenirs (173). The major continuing cost is food; approximately 4000-5000 kg of waste fish are needed daily at a cost of US$0.20 kg-l (173). OTHER INFORMATION The farm was established with the following objectives (212) :- a) Preservation of crocodiles; b) Commercial production; c) Tourism. It is the only major farm in that part of the world producing commercial quantities of crocodiles (40). Tiger, snake and lizard farms are also planned by the farm (173). Besides the crocodilians there are 48 other species of native and exotic reptiles on show (173), as well as birds and mammals. Pythons are kept in large numbers and are bred (211). Other species kept include elephant, lion, tiger, leopard, chimpanzee, gibbon, deer, bears, wild pigs, civets, wild cats and birds (57, 172). The animals are reported to be kept in small, dirty pens (57). "Leather' magazine (12) named Samutprakan Crocodile Farm, near Bangkok, as the 'Gordon Choisy Crocodile Farm'. Gordon Choisy own a leather tannery in Paris, France. 156 TOGO rae a1 Sy7/, UGANDA The Kajansi Fish Culture Station, 12 km south of Kampala, introduced a crocodile-rearing programme, in 1959, as a conservation measure. In 1984, 18 very large Crocodylus niloticus and a number of smaller animals were being kept in neglected pens. The Station is in danger of discontinuing its crocodile rearing as it cannot afford food for the crocodiles (43). 158 UNITED STATES OF AMERICA General Information The first records of "farming" alligators in the USA date from the end of the last century when a few entrepreneurs started keeping alligators as tourist attractions (40). Such operators continue today and, in Louisiana, are now termed "exhibitors" to distinguish them from "farmers" who are interested in the commercial products of alligators: skins, meat and live sales. The first commercial farms started in Louisiana, in 1954, but very few skins were produced (105). Farms were later established in Florida but they developed at a slow rate, and it was not until the summer of 1978 that they sold their first captive-raised skins (40). SPECIES AND NUMBERS The only species of crocodilian which is farmed commercially in the USA is Alligator mississippiensis. The table gives a summary of the numbers of farms which have been in existence in Louisiana (LA) and Florida (FL). Although the total numbers of farms in Louisiana has not changed much, many individual farms have been put into liquidation and new farms have started up. One farm is reported in Texas.

About 150 of these have subsequently been released in Mexico. Other species which have been bred include Crocodylus intermedius, Crocodylus siamensis, Crocodylus acutus, Crocodylus niloticus, Crocodylus porosus, Crocodylus rhombifer, Crocodylus cataphractus, Alligator sinensis, Caiman crocodilus, Osteolaemus tetraspis and Paleosuchus trigonatus (186). 159 U.S.A. PRODUCTION AND TRADE Harvesting of wild alligators takes place in Florida, Louisiana and on a small scale in Texas. In 1983 the harvest in Louisiana amounted to 16 154 alligators, 8% of the estimated population, and produced 100 000 lb (45.5 t) of meat (195). The total skin production from farms in the State in 1984 was 1113 (103). Total farm skin production in Florida was 112 in 1983 but a further 1031 live animals were sold (25). In 1984 a total of 738 skins were produced from farms in Florida (67). In 1981 there were more than 200 restaurants serving alligator meat in Florida. Farm-raised meat was said to fetch a premium price because of better processing and to have sold for US$10 a pound ($22 kg-l). Other by-products such as feet and heads as curios and gall bladders and penes for the Far Eastern market were said to be potentially valued at up US$20-50 per animal although with current marketing practice US$5 would be a more reasonable sum (41). Whitaker et al. (204) quoted more modest prices in 1985 of US$10 kg-1 for meat and US$20 for lacquered skulls in the USA, with US$25 kg-1 for oil, US$5 each for dried gall bladders and US$5 a pair of dried scent glands obtainable in Hong Kong. In Florida licences are issued to take “nuisance” alligators, and up to 1980 about 2000 such animals were being taken each year (30). An experimental harvest was initiated in 1981 on the Orange and Lochloosa Lakes and, until 1984, an annual average harvest of 330 alligators greater than 1.2 m in length was taken (96). All trade in alligator products, whether farmed or wild-caught, is strictly regulated. Skins and meat must be tagged or labelled with tags issued by the State Authorities, and the killing and sale or processing of products of alligators also require licences. Alligator mississippiensis is listed on the US Endangered Species Act, and tanners of alligator skins and buyers who wish to engage in inter-state commerce of raw skins must hold a permit from the US Fish and Wildlife Service (USFWS). The killing of alligators reared in captivity requires a Federal farming permit from the USFWS. Full details of the stock held and whether it derives from the wild or is captive-born must be submitted with the permit application. Health regulations are set in each State controlling the slaughter and processing conditions for meat destined for human consumption. SOURCE OF ANIMALS The Louisiana ranch stocks are being supplemented with wild-caught animals during their first five to seven years of operation to help them acquire breeding stock and expand their operations. The farms so supplied must comply with specified standards of facilities and planning. Some type of environmental chamber to house juvenile alligators over winter must be available, and farmers must, if required, return to the State live alligators of length 0.9m representing 5% of the hatchlings supplied. Periodic inspections are carried out, and farmers must submit annual reports of stock and husbandry records (105). In 1984 Louisiana Rockefeller Refuge supplied a total of 5050 hatchlings to farmers in the State, two-thirds of which derived from wild-collected eggs, and the remainder from eggs laid in captivity (103). In Florida a programme to evaluate the impact of removing eggs and hatchlings from the wild was initiated in 1981. This relies ona 160 U.S.A. helicopter to locate the nests, directing ground teams in airboats to make the collection. Using three boats, up to 1800 eggs have been collected in an 8-hour period. Hatchlings are mostly collected at night from boats. Collection costs in 1984 were about US$5 an egg and US$7.32-12.86 a hatchling (96). At least 3217 hatchlings were supplied to farmers in 1984 by this supplement programme (67). BREEDING In 1980 the five active Florida ranches were collectively producing an average of 2500 hatchlings a year (40). In 1983 2635 hatchlings were produced from 6 ranches (25). In 1984 breeding took place on 11 ranches, producing a total of 4075 surviving hatchlings. These were derived from a total of 11 818 eggs laid, giving a mean hatching succcess rate of 34% (range 0-81%). The mean number of eggs per nest was 33.0 (67). Only one of the Louisiana ranches was breeding alligators in 1984, when it produced 1800 hatchlings (103). HUSBANDRY According to Ashley (40) an area of at least 10 acres (4.2 ha) is needed for an alligator farm. Breeding ponds have to be constructed, and wells and pumps adequate to maintain water levels are essential. Concrete rearing pools capable of housing 500 to 1000 alligators of each age class would also have to be constructed. Storage facilities, freezers, coolers, food preparation areas, and skinning and handling areas are also needed. FINANCES = Running costs for an alligator ranch were estimated in 1980 to total between US$50 000 and US$200 000 over the first three years (40). Based on average values of US$49.21 a linear metre for skins and US$11.02 kg-l for meat, farmed animals were worth about US$200-300 at slaughter in 1984. The costs of raising a hatchling to this size were estimated to be US$75-100 which, assuming a 903 survival rate, gave a profit of US$125 per animal. Very large wild-killed animals of 3.5m have raised over US$1000 each (96). Ashley (41) gave a value in 1981 of US$355 for each animal, comprising US$170 for a 17" (43-cm) belly-width hide and US$175 for 25 lb of meat (US$15.4 kg-l). 161 U.S.A. Louisiana NAME OF OPERATION Rockefeller Wildlife Refuge, captive propagation project Rockefeller Refuge, Grand Chenier, Louisiana. Operated by: Louisiana Department of Wildlife and Fisheries. DATE OF ESTABLISHMENT In 1959 the Louisiana Department of Wildlife and Fisheries initiated an alligator research programme involving Alligator mississippiensis, in two parts: i) field studies on life history; ii) a culture programme incorporating the facts derived from the field study (considering reproductive activity, stocking density, food requirements and social order). The aim of the programme was to demonstrate the feasibility of raising alligators in captivity (104). The Louisiana Department of Wildlife and Fisheries controls all alligator harvest and farming activities in the State. The Rockefeller Refuge maintains incubation facilities to supply hatchlings to farmers. In 1984 two-thirds of the hatchlings supplied to farmers in the State derived from wild-collected eggs and one third from eggs laid at the Refuge (103). In 1976 an Alligator sinensis propagation programme was begun (107). SPECIES AND NUMBERS A. mississippiensis: about 200 broodstock were kept in 1978 (105). A. sinensis: this operation is based on three mature alligators (44). PRODUCTION AND TRADE The operation is a conservation project and does not produce animals for trade (107). It does, however, supply the hatchlings from wild-collected, artificially incubated eggs to farmers. In 1984 a total of 5050 hatchlings were supplied to 9 farmers (103). The A. sinensis offspring produced have been transferred to the New York Zoological Park and the Texas Zoological Park at Houston (45). SOURCE OF ANIMALS A. mississippiensis: This operation was based on wild-caught stock and eggs. The eggs collected from the wild within 24 hours of being laid or after the 4th week of incubation produced the greatest success in the farm-incubation (104). A. sSinensis: All of the animals were obtained from captive sources. The original four adult alligators were from the New York Zoological Park and the U.S. National Zoological Park (107). BREEDING A. _mississippiensis: The first farming efforts involved capturing wild alligators and housing them in large breeding ponds. A stocking rate of one male and one female in each pen (0.4 ha) produced successful nesting. Attempts to keep several females with one male resulted in fighting and mortality. Subsequent improvements to the pen design to mimic natural conditions allowed higher stocking rates. Multiple nesting of wild adult females was achieved only after small isolation ponds were added to the breeding enclosures (104). Use of wild-caught adults as breeders proved impractical because they were found to require more space than animals reared in captivity; but these animals did provide a source of eggs which later formed the 162 U.S.A. basis for future breeding stock for a commercially acceptable breeding programme (107). Age at first nesting, for alligators raised in chambers for three years then transferred to outside pens, was 5 years 10 months compared to 9 years 10 months for wild animals, but reproductive success may not be comparable until the captive-reared animals reach 10 years. The fecundity, fertility and hatching success all increased with age. By the fourth year of breeding the clutch size was approaching 39 eggs, the average for wild nests. Egg fertility of cultured stock averaged only 47% over three years, compared with 87.5% for wild-caught animals reared in pens. Hatchability was also lower at 443% compared to 58% for wild-caught animals (107). Eggs were incubated at 29-33°C in trays, supported over water, completely enclosed in natural nesting materials to aid degradation of the eggshell (104). Hatching success was found to be best at a temperature of 31-31.7°C (105). A. _Sinensis: The operation had some trouble in producing offspring at first but after a change in the diet, has had some success. In 1977 one hatchling was produced, however it died within six weeks. In 1979 four young were successfully raised and in 1980, 24 were raised. Over this period the hatching success rate works out to be approximately 503 (45). HUSBANDRY Wild-caught adults were found to require 10 times more space than Captive-reared animals. Stocking rates for captive-reared animals ranged from 12-46 adults 0.4 ha-l. Juveniles up to three years of age were kept in environmental chambers maintained at 29-32°C, Stocking densities were held at 10m 2 for the first year and were then reduced to 3.3 m-2 for older animals (107). The feeding rate was 25% of body weight a week for the first year reducing to 18% by the end of the third year. The alligators were fed on fish (Micropogon undulatus) or nutria (Myocastor coypus). The nutria-fed animals were 20% heavier and 3% longer on average than the fish-fed animals, at the end of the study. Behavioural differences were also observed, the nutria-fed animals being more active and aggressive. On a fish diet 49.5% of the dry weight of food fed was converted to body weight over a 33-month period. The feeding rate of adults in Outside pens was approximately 6-7% of body weight a week (104). Mortality of hatched animals was less than 5% for the three-year Study (104). FINANCES In 1973-75 it was estimated that it cost US$20 to raise one alligator to an age of 33 months. This included all running costs, but excluded labour and capital outlay (107). The A. Sinensis project is financed by the New York Zoological Society (107). RESEARCH AND PUBLICATIONS Researchers who have worked at Rockefeller Refuge include M.J.W. Ferguson, from Manchester University, and V. Lance from Tourlane University, New Orleans. Results from the operation have been published in a number of articles including those used as references here. 163 U.S.A. OTHER INFORMATION The A. sinensis project was initiated in response to the decline of the species in the wild and began with a pooling of adult specimens already in the USA for propagation purposes. The Rockefeller Refuge was chosen as the site for the captive-breeding project as this was seen to be the closest possible substitute for the animals natural habitat available in the USA. Production of offspring from the operation is hoped to provide a source of animals for the captive population (45). ses *%s==%===%=== NAME OF OPERATION Cocodrie Farms 9034 S.

As these animals mature and begin to breed successfully the ranch should become self-sustaining with regard to stock (110). During 1983 these animals first attempted nesting. Four clutches comprising 113 eggs were laid, from which 14 young hatched (136). HUSBANDRY The adult animals are kept in a 1.5-acre (0.62-ha) ‘natural habitat" enclosure enclosed by a 6 ft (1.83-m) chain-link fence. The juveniles are kept in completely enclosed heated chambers measuring 10 ft x 32 ft (3.05 m x 9.75 m), with drains and a fresh water source (109). The alligators are fed mainly on non-oily saltwater fish but also on red meat procured during the local trapping season (110). FINANCES The operation is privately financed and was not self-financing in 1983 (109). - NAME OF OPERATION Sauros Inc. RTI Box 270A Bell City LA 70630. Operated by: Emilie D. Perkins.

A total of 1031 live alligators were sold during 1983, 996 juveniles and 35 breeding stock (25). No skins were sold in 1984 (67). BREEDING 1389 eggs were laid in 1983 in a total of 46 clutches. From these 1053 hatched, of which 1000 survived until 31 December 1983 (25). At Lake Park the broodstock was kept in two natural ponds, several acres in size. In 1980 40 nests were laid, from which it was hoped to hatch 800 young at an average hatching rate of 65%. Eggs are removed from the nests and incubated artificially in trays containing decomposing vegetation (30). HUSBANDRY At Lake Park hatchlings up to one year old were reared in enclosed chambers measuring 5 ft x 6 ft x 14 in (1.52 m x 1.83 m x 0.36 m) with 100 in each. 100 two-year-olds were reared in each open pen measuring 6 ft x 12 ft (1.83 m x 3.66 m), and 3- to 4-year-olds are kept in larger pens, measuring 20 ft x 20 ft (6.10 m), again with 100 in each. Alligators reared in these pens were found to be more easy to manage than those reared in natural pens (30). It is not known what facilities are available at the new site at Christmas. Food is mostly mixed saltwater fish and chicken necks. Breeding females are given vitamin supplements (30). 172 U.S.A. FINANCES In 1980 skins were selling at about US$7 a belly inch ($2.76 cm-l), and the meat, which was supplied to local gourmet restaurants, at US$6 1b71 ($13.20 kg-l). A 6-£t (1.83-m) alligator weighs about 80 lb (36 kg), half of which is meat. This therefore fetched twice the value of the skin (30). OTHER INFORMATION Turtles (Trionyx spp.) were also being bred for the pet trade, hatchlings fetching US$2 each (30). === *===*%===*=== NAME OF OPERATION Rt. 1, Box 340 Bell FL 32619.

However the Ministerio del Ambiente y los Recursos Naturales Renovables (MARNR), encouraged by the recovery of wild populations of Caiman _crocodilus, has recently proposed a possible multi-level Management scheme for skin exploitation of this species. An experimental scheme allows for a controlled harvest of caimans mainly on private ranches, based on population estimates conducted by MARNR (152). The means by which these estimates are produced and the level of the harvest are under discussion. It iS proposed that the population should receive continued protection outwith the licensed harvest and several measures have been Suggested to encourage the wild population. At the lowest level this would involve the protection of nesting areas and ponds’ from agricultural pressures. More active assistance could be provided by constructing ponds in regions where they normally dry up in the dry season, the relocation of threatened groups of juveniles, and the control or exclusion of predators. Other options under consideration are _ ranching, either by collecting and incubating caiman eggs and releasing the juveniles, or by rearing them to commercial size in captivity. The MARNR already runs an experimental centre to investigate techniques of captive rearing. As a result of this experience it recommended, in 1982, taking eggs from the nests of wild crocodiles, and incubating them; raising the hatchlings in 1m x 3m tanks, with 100 animals to a tank, for one year; feeding the young on small fish, finely chopped meat and insects, which would be attracted to the tanks at night by bright lights hanging above. After one year the young caiman would be returned to semi-wild conditions in the form of fenced-off natural lakes and rivers where again they would be fed on fish and meat, The animals would be harvested after three years for their skins, the meat being fed back to the younger stock (17). Two private ranches in the Llanos region, Hato Masaguaral and Hato El Frio, have been keeping Crocodylus intermedius and have succeeded in breeding them. Some hatchlings have been released to the wild, but this is purely a conservation exercise, as the wild population is too low to allow exploitation at present. Experiments have also begun on collecting and incubating eggs of Caiman _crocodilus_to evaluate the shbatsesth eedgasing juveniles, on the potential harvest of the wild 183 WESTERN SAMOA According to a newspaper report in 1981, a West German proposed to build a crocodile farm on the island (21). No more has been heard of the proposal, but the Government Director of Agriculture and Forests declared that there was no wildlife farming of any kind in 1983 (156). 184 ZAMBIA There are up to four crocodile farms in Zambia, but only two of these are operating on a large scale. The first was established in 1980. NAME OF OPERATION Kariba Crocodile and Fish Farms Ltd P.O. Box 34284 Lusaka Zambia. Director: Mr G.J. Parker. DATE OF ESTABLISHMENT 1981 SPECIES AND NUMBERS Crocodylus niloticus: around 2000 crocodiles were held in 1984, consisting of 800 two-year-olds, 800 one-year-olds and 400 hatchlings (139). The stock later in 1984 was reported to be 2273 animals (176). PRODUCTION AND TRADE In 1982, 90 farm-raised crocodiles were expected to be ready for marketing by the end of 1983 (18), however no commercial production took place (138). It was hoped that the sale of skins to French tanners would commence in 1985 (139). SOURCE OF ANIMALS All stock has been obtained from the wild. Eggs have been collected in Zambia under Government licence and hatched at the farm. The Government controls the number of eggs allowed to be taken and the areas from which this can be done. They then demand the release of 103% of the stock after two years (138). Eggs obtained from the wild and hatching success 1981-82 Year Number of eggs Number hatched Hatch rate obtained 1981 1655 1417 86% 1982 880 794 90% (138) The quota for the collection of eggs in 1984 was 4000 (176). The operation hoped to be permitted to catch adult animals for breeding purposes in 1984. The Zambian Government requires the Operation to have suitable holding facilities prepared before they will issue licences to capture adult crocodiles (139). BREEDING Breeding has not yet commenced on the farm as the rearing stock is still immature (138), however there are plans to acquire a breeding nucleus of 10 females and two males from the wild (176). HUSBANDRY The animals are held in concrete enclosures of approximately 60% land and 40% water. They are fed on small whole fish, obtained from the fishing aspect of the operation, and some goat meat (138). The farm was reported to be experiencing difficulties with the water system and hygiene in 1984 (176). FINANCES The operation depends upon the commercial fishery run in conjunction with it on Lake Kariba, Zambia, for both income and feed (138). 185 Zambia RESEARCH AND PUBLICATIONS Research is carried out by Gordon Parker mainly for the Zambian Government. Nesting data are collected for Mr G.B. Kaweche, Chief Research Officer of the Zambia National Parks and Wildlife Service, and it is proposed that data on reproductive biology will be collected when breeding starts (138). OTHER INFORMATION Eggs are collected from Game Management areas and Open Areas only (138). NAME OF OPERATION The farm is located by Lake Tanganyika. Director: Mr A. Carr.

SOURCE OF ANIMALS The farm had a quota to collect 5000 eggs and 25 adult breeding crocodiles in 1984 (176). sa= *¥ === ¥===*¥ === A farm owned by Mr A. Bowyer is reported to exist at Siavonga, on Lake Kariba. In 1982 he obtained permission to collect 1000 eggs on the Zambezi (206). The present status is uncertain, and the farm was not mentioned by Tello in 1985 (176). 186 ZIMBABWE General Information Nile crocodiles have been ranched in Zimbabwe since 1965; there are now six crocodile ranches in existence there. Three further ranches existed previously but were all short-lived. Binga Ranch, Karoi Ranch and Mini Crocodile Ranch were established at Lake Kariba in 1965, 1966 and 1967 respectively, but all closed within two years (66). SPECIES AND NUMBERS Crocodylus niloticus: In 1984 there were a total of 27 704 animals on the ranches comprising 16 000 rearing stock, 11 466 hatchlings, 52 Mature males and 186 mature females (55). Approximate figures for the total stock on farms in previous years are given below (66): Year Stock Year Stock 1967 1400 LOTT 9000 1968 2400 1978 - 1969 3700 1979 15500 1970 5000 1980 20000 1971 6000 1981 20000 1972 6600 ) 1982 24000 1973 7300 1983 28500 1974 7100 1975 9000 1976 - PRODUCTION AND TRADE In the 1981 season, 2890 skins were produced for export from Zimbabwe (179). On projected hatching of juveniles in 1984/85 the potential production in 1987/88 is 13 850 skins (55). Approximately 10-34% of the animals over one year of age are Slaughtered each year. Skin sales from farms can be expected to grow at about 22% a year. In 1984 the industry was said to generate US$334 000 a year in foreign exchange (66). Zimbabwe's annual report to CITES for 1983 reported the following commercial exports of skins and live animals: Quantity Product Destination 427 Live South Africa 66 Skins South Africa 25 Skins UK 860 Skins France All exports are currently through the Crocodile Farmers Association of Zimbabwe. When the Zimbabwe population of Crocodylus niloticus was on CITES App. I the skins were marketed only in France. However, enquiries about the purchase of products had come from the UK, F.R. Germany, Switzerland, USA, Canada and Japan (179). The population was transferred to Appendix II in 1983 and sales are now also made to other countries. The skins of animals ranched in Zimbabwe are tagged to show their origin and the numbers of the tags on skins exported must correspond 187 Zimbabwe with the record on the export permit; the records are also kept by the Zimbabwe Department of National Parks and Wild Life Management. The tags come in two parts which, once clipped together, cannot be reused. Prior to issue the two sections are kept Separately, one kept by the Crocodile Farmers' Association and one by the Department. Skins must be tagged on a specified margin which is varied from time to time (66). SOURCE OF ANIMALS Crocodile ranching was experimentally introduced into Zimbabwe with the emphasis placed on collecting eggs from good breeding population areas, artificially incubating them and rearing the hatchlings (40). From 1967 to 1973 a total of 22 679 eggs were collected and 16 679 were hatched, giving a mean hatching success rate of 73.5% (40). From 1979 to 1983 a total of 38 077 eggs were collected, hatching with a success of 88.6% (66). Eggs are normally collected in early November, 50-60 days after laying, when they may be moved with less danger of damage. Experienced collectors can distinguish between fertile and infertile eggs, and collect only the former. This may explain some of the reported improved hatching percentage. The eggs are incubated in moist vermiculite in styrofoam boxes stored in a temperature-controlled shed at about 32°C. Hatching usually occurs in late December (66). The stocks come from "Government egg supplementary programmes" and each ranch is annually designated an egg-collecting area and a number of eggs that may be collected (180): Egg-collecting Captive-breeding stock Station Current Increase Total Females Males quota Binga 2500 - 2500 72 (40) 15 (10) Kariba 2000 - 2000 62 (40) 20 (10) Rokari 1000 1000 2000 (40) (10) Sengwa Mouth 2000 500 2500 (40) (10) Spencers Creek 2500 - 2500 -94 (30) 20 (figures in brackets "are from present capture programmes initiated by National Parks and Wild Life Management and should be completed before May 1983. Unbracketed figures are stock on hand currently capable of breeding" in 1982 180) The capture programme will probably not be completed until 1985 (182). The captive-breeding stock comes from the ranches' own hatched stock or from problem-animal control programmes. Every effort is made by the Department of National Parks and Wildlife Management to capture problem animals from the wild, and there are severe and strictly enforced penalties for poaching and unauthorised killings. A maximum of twelve crocodiles a year have been allocated to registered safari hunting operations. The ranches provide a safe repository for wild animals which have genuinely become a menace to humans and livestock (179). 188 a a Zimbabwe The total numbers of eggs collected from the wild from 1979 to 1983 and the hatching success is given below (66): Year No. No. Hatching collected hatched success 1979 5279 4497 85.2% 1980 8079 7069 Bie5e 1981 8768 7879 89.9% 1982 10389 8943 86.13% 1983 10908 - 9961 313s BREEDING The ranches had breeding facilities involving 152 crocodiles and a production of 3000 eggs in 1982. The hatching percentage and numbers are expected to increase each year, however, to retain viability it is necessary to supplement the breeding stocks with the collection of eggs from the wild (179). In 1984 there was a total breeding stock of 186 females which were expected to produce 13 440 hatchlings in 1984/85 (55). Initially equal numbers of males and females were kept but this was found to be unnecesSary as each male can serve up to 20 females (66). From 1979 to 1983 a total of 8828 eggs were laid at two farms, which had an average hatching success of 72.7% (66). HUSBANDRY All five ranches operate under a closed incubation/hatchery construction. Hatchlings are removed to open pens, are graded by size and condition and are housed in densities calculated to minimise stress. Originally earth ponds were used but problems were experienced with burrowing, and now most ponds are of concrete. In the first year of life about 150-200 animals are kept in each pen, comprising two ponds 10-15 m long by 1.5 m wide by 60 cm deep. Later they are moved to larger pens (ca 20 m by 8 m) with 75-100 animals in each. They are initially fed on freshwater sardine known as kapenta (Limnothrissa miodon) and later on elephant meat (supplied under special permit from the Dept. of National Parks and Wild Life Management) to which is added bone meal, vitamins and trace elements (66). The animals are normally slaughtered at 2-4 years old at a length of 1.5 m, when their belly skin is about 35 cm wide. Each animal is shot in the head with a short .22 bullet. Eviscerated carcases are fed back to the other crocodiles as no market has been developed for the meat (66). FINANCES A financial analysis reported in 1982 that the average cost per egg was US$2.49 for those collected from the wild and US$1.25 for those laid on the farm. It was found that the cost of feeding one male and 10 females was US$457 a year, food consumption averaging at 5.6% of the body weight a year (80). Whitaker et al. reported that lacquered skulls and feet sold as curios for US$10 and US$2.5 respectively. Back skins, for use in belt Manufacture, were worth a further US$20 (204). 189 Zimbabwe OTHER INFORMATION Crocodile farmers in Zimbabwe must provide the Department of National Parks and Wild Life Management with a monthly return of stock on hand, hatchlings, deaths, killings, eggs collected and hatches. Government policy requires that some suitably-sized crocodiles be made available for reintroduction for conservation purposes. Originally this was set at 10% of the eggs or hatchlings collected, but this was later reduced to 5% (66). This availability "is in the form of crocodiles of a size suitable for restocking denuded habitats, augmenting wild populations, research or the meeting of international obligations" (179). No return of stock took place from 1978 to 1984 and the Department of National Parks and Wildlife Management has waived its right to its quota for these years (55). A total of 910 animals have been returned to the wild under this scheme, and a further 30 used for research or donated to other countries (66). 190 Zimbabwe The Operations NAME OF OPERATION Binga Crocodile Farm P.O.Box 16, Binga, Lake Kariba West.

A total breeding stock of 33 animals (30 females and 3 males) exists; 27 six= -year-old ranch-reared crocodiles, and 6 wild-caught animals purchased 191 Zimbabwe from the National Parks. The breeding stock is held in _ separate breeding pens (184). The first breeding occurred on the farm in 1983 when a total of 60 eggs were laid (66). See also General Information, above. HUSBANDRY The crocodiles are kept in two types of enclosures: a) Conerete pools with cement feeding apron and areas of lawn grass, enclosed by brick walls; b) Natural earth ponds enclosed by sheet metal fencing. Fresh food is provided to all pools in the form of freshwater sardine and elephant meat (184). Mortality of animals in excess of one year-old averaged 5% from 1981 to 1983.
