PART I, COMMERCIAL FISHES. By ALvin SEALE. (From the Bureau of Science, Manila, P. I.) INTRODUCTION. We have received numerous requests for information regarding the commercial fisheries of the Philippine Islands, especially relating to the different kinds of edible fish and their abundance; the location of fishing hanks and the methods of capture. We have also been asked if fishing, entered into as a commercial venture, would be profitable. It is for the purpose of answering some of these questions that Part I of this series, based on my personal observation in the various islands of the group during the past year and a half, has been prepared. It is hoped that this paper, together with others to follow—namely, Part IT, Sponge Fisheries: Part Il], Pearl Fisheries; Part IV, Other Marine Products (aside from fishes. pearl oysters, and sponges)—will serve to create an interest and help in the development of the rich fishery assets of the Islands. THE ANCHOVIES. Family Engranlide. (PI. 1.) There are at least four different species of anchovies in the Philippine waters, the most abundant, perhaps, being Anchovia commersoniana (Lacépéde), called dilis in Tagalog, monamon in Ilokano, and anakbat in Moro. Anchovia dussumiert Bleeker, termed dumpilas in Tagalog, and teggui in Moro is a large species, but less abundant than the dilis. The common anchovy (dilis) is found in great numbers along the shores of almost all the islands of the group; it is almost transparent, with very thin, deciduous scales. This species is a delicate little fish of fine flavor and would bring a good price, if put up in attractive form either in oil or spice, or if made into anchovy paste. 513 ol4 SEALE. THE HERRINGS. Family Clupeide. (PI. II.) There are about thirteen distinct species of herring represented in the Philippine waters and notwithstanding their rather small size, they are of considerable commercial importance. They abound in immense num- bers along the coasts of almost all the islands of the group. Some are more or less migratory, others seem to remain near one place. Large numbers are caught in Manila Bay at all seasons of the year. These represent the forms called tunsoy [{farengula moluccensis (Bleeker) ], tamban (H. longiceps Bleeker), and bilis [H. gibbosa (Bleeker)]. The young of all species are termed silifiaxi. Great numbers are caught in corrals, especially during May and June; they are also taken in the drag- seine. It is not an unusual sight to see large bancas loaded to the guuwale with herring being landed at Tondo beach, where the fish are sold to the Chinese to be smoked and dried. The natives in Zamboanga buy large quantities to eat in the fresh state. \ny of these sardines would compare favorably with the species put up in oil on the Pacific coast. During the nine months from January first to September first, 1907, 85,000 pesos worth of canned sardines were imported into the Philip- pines; this, too, with the Philippine waters swarming with sardines and with an abundance of good sesame oil which could be used for canning purposes, produced in Manila. THE SILVERSIDES. Family Atherinide. (Pl. IIT.) The silverside, called guno in Tagalog and Moro, and ti-i in [lokano, is without doubt the most abundant fish in the Philippines. It is almost impossible to land at any wharf or go ashore on any beach without seeing these little fish in countless numbers. They usually grow to a length of from 10 to 12 centimeters. They have a greenish tint on the back and a bright, silvery band on the sides. There are five or six different species, but they appear so much alike that the natives have not distinguished between them, calling all simply guno. The most common species is possibly .ltherina temminchki (Bleeker). The guno are known as pescados del rey, “fishes of the king,’ among the Spaniards. They are greatly valued as food. The young are termed whitebait. The method of catching is usually by seine or corral. A profitable industry could be built up by preparing these fish in a good sauce, by pickling them with spices, or by drying. An abundant supply FISHERY RESOURCES OF THE PHILIPPINES, [. 15 for canning operations could be secured at any of the following places: Manila, Jolo, Zamboanga, Sitanki, Puerto Princesa, and perhaps a dozen other places not yet examined. They abound at all seasons. THE MACKERELS, Family Seombrida. (Pl. IV.) There are at least eight different species of the mackerel family found in the Philippines, all of them good food fishes and of commercial importance. In this family is the tanguingue, also called tangili or tangt (Moro), which is a true Spanish mackerel (Scomberomorus com- mersont Lacépéde). By many people this is regarded as the finest food fish in the Philippine waters. This fish is fairly abundant, and can usually be found in the markets, where it sells from 1 to + pesos, Philippine currency (50 cents to 2 dollars United States currency) per fish. At Zamboanga it is nothing unusual to see ten or a dozen of these fish in the market at one time, all of them measuring 90 centimeters or more in length. They are frequently cut up and sold by slices. The major part of the tanguingue are caught off shore with a hook and line, a good fishing ground being located off the east coast of Basilan. At Manila they are usually caught in nets. Another Spanish mackerel taken in these waters is Scomberomorus konam (Bleeker), which is scarcely distinguishable from the above. Other important members of the family are the chub mackerels (alu- mehan or cavallas), Scomber microlepidotus Riippell, and the hasa-hasa (Scomber japonicus Houttuyn). These fish ran in great shoals through- out the Islands, following small fish, upon which they feed. Thev enter Manila Bay in March and the inhabitants along the shore-line of the bay are kept awake during the nights by the noisy clatter of the fishermen beating with their paddles against the sides of their boats in order to frighten these much desired fish into the nets or hastily con- structed corrals. Still other members of this family represented in these waters are the small bonitoes (sobad or tulittyan) (ymnosarda pelamis (Linn.), the great tunnies (also called sobad), and the albacore (Germo alalunga Bleeker). All of these fish may be caught with hook and line, in nets or corrals. They are so abundant that it is unusual to make a trip among the Islands without sighting ope or more shoals of fish belonging to this family. They are especially common about the Cuyo group and along the shores of Palawan. The market at Zamboanga is usually well stocked with all members of the family. They are with few exceptions fishes of the deep water. The purse-seine in my opinion could be profitably employed in their capture. O16 SEALE, THE MUD FISILES. Family Ophioccphatide. (Pl Vo) ‘The mud fishes, dalag (daluk in Moro), are of considerable impor- tance, especially in the vicinity of Manila where they form a large part of the food of the native population. They are usually sold alive in the markets. In fact, it is their ability to stay alive out of water that attracts attention to them. They are primarily a fresh- or brackish- water fish, and after a rain almost all the little pools by the wayside. as well as the paddies and rivers are well filled with dalag. They have the habit of burying themselves in the mud as the ponds dry up and thus of lying dormant until the next rain. They take the hook freely, and it is no uncommon sight to see the natives fishing for them in the rice-fields, or in the most unlikely and recently formed pools. They frequently travel overland in the wet grass and can live for hours out of water. The egys are deposited in holes in the bank; the mother exercises a care over the young fish. In India these are regarded as one of the most wholesome fishes and are given to invalids. In Manila they are looked upon more as scavengers and are not much eaten by the Americans. These mud fish are distinctly carnivorous, feeding on small fish, refuse, etc. Thev are well distributed over the Islands, being found in almost all the lakes and rivers. THE SNAPVERS. Family Litiqnida, (PL VIL) There are about twenty different spevies of this family in the Philip- pine waters, all of them important as food fishes. They range when full grown from 25 to 90 centimeters in length. They are distributed over the entire group, some running up rivers to the interior lakes to feed. Several of the species are bright red in color and are called red snappers, one of the most abundant being the buchwn [Lutianus dodecacanthus (Bleeker) |. Another snapper called the camangbuhu (Lutianus fuscescens Cuy. ot Val.) can usually be found in the markets, especially in Zamboanga. .\ very important member of the family is the aleis (hatumbang in Moro) (Lutianus yembra Bloch et Schn.). These are caught in great numbers in the Naujan River at Batos, Min- doro. The adults weigh from 8 to 20 pounds each. I saw 108 of these fish caught in one-half day at the Batos corral. The best banks for red snapper fishing seem to he in the vicinity of Zamboanga. Dapa and managat are other Moro names applied to the red snapper. They are usually caught by hook and line, or in the corral. In Zamboanga a red snapper 35 centimeters long can be bought for 40 centavos. FISTIERY RESOURCES OF THE PHILIPPINES, J. yl THE POMPANOS. Family Carangida. (Pl. VII.) There are thirty-six different species of the pompano family known in the Philippines. All of them are valuable commercial fishes. The cavallas (Caranv) are the most important branch of the family. ‘They are termed talahitok in Tagalog and daingputi in Moro. ‘These fish are very abundant in almost all markets. They range from 32 to 36 centi- meters in length. As a rule they are caught in corrals. Another abundant species is the lison [Caranx ignobilis (Forskal) |. These fish are dried in large numbers by the Moros. The ballangoan. termed cubal-cubal (Megalaspis cordyla Linn.), is another very abundant food fish of fine flavor, belonging to this family. These are reported to reach the length of 155 centimeters; ordinarily those in the market measure about 45 centimeters. They are caught in corrals. THE SEA BASSES. Family Serranide. (PI. VIII.) There are thirty-three species of this important family of food fish reported from the Philippines. One of the most familiar is the apahay (tapog in Moro) [Lates calcarifer (Bloch)], one of our largest sea basses. Specimens weighing from 25 to 35 kilos are frequently brought into the market. ‘This fish would afford good sport for local anglers. The largest branch of the family is constituted by the groupers (Epine- phelus), called lapo-lapo in Tagalog, garopa in Visayan, and kukkut in Moro. (Pl. VIII.) Ordinarily this name is given to the most common species, Myinephelus merra Bloch, but it is also applied to at least three others which closely resemble £. merru. These fish brmg a high price in the Manila market; they are a favorite sea food for many Americans. Another rather common species is the blue-spotted grouper [Cephalo- pholis stigmatopomus (Richardson) ], which is especially abundant in the Zamboanga market. The fishes of this family are usually caught with hook and line in water of considerable depth; sometimes they are taken hy net or corral. Gill-nets set in about 50 feet of water frequently make good catches. THE MULLETS. Family Mugiltidw. (Pl. IX.) There are ten different species of mullet recorded from the Philippines, the most abundant being the banak (Mugil cephalus Linn.). This fish can always be found in the market and when quite fresh and properly cooked is most delicious. It is very common throughout the entire Archipelago. The mullet is a strictly vegetable feeder, and is usually o1s SEALE. found wherever there is an abundance of sea iuoss. The shallow sea about the Island of Sitanki is a famous feeding ground for this fish. On the morning of June 29 of this year I witnessed a most astonishing movement of mullet near the Island of Sitanki, Sulu Archipelago. A noise like a great waterfall was heard. Hastening to the beach I saw a vast shoal of the fish coming from the north, keeping quite near the shore; they were leaping along ihe water in great, flashing waves. The shoal was fully 100 yards wide and 500 yards long; there must have been over a million individuals in it. The fish seemed to be of almost uniform size, about 40 centimeters in length. Nothing stopped them. The natives jumped into the water and killed hundreds with sticks and stolles; some were driven ashore, but the shoal passed, leaping, on to the south, These fish were probably seeking a new feeding ground. They were not breeding, this fact being indicated by the extreme smallness of the ovaries. I should estimate that there were over one hundred thousand pesos’ worth of fish in this one lot. Several species of this family run up the fresl water rivers to the lakes. As many as ten thousand have been caught at one time with a drag-seine near the mouth of the Naujan River in Mindoro. These fish are easily dried and are a good commercial asset. OTHER COMMERCIAL TISFLES. There are many other fishes in the Islands that are of commercial importance, but lack of space and time will not permit of a detailed description. However, among these we should mention the barracuda, called panyaloan or lambanak in Moro. This is an abundant and excellent food fish sometimes reaching the length of 1.5 meters. There are also numerous species of porgies, termed bitil/a, cutcut, and quntul by the natives. These fish are especially abundant ahout Nitanki, and there they are dried in large numbers. Many members of the grunt family (Hemulidir) ave also seen, these are termed Jeff, paxinco, bakuku, and bagong;* they are especially valuable for salting and drying. Several members of the gar family (Belonida), the croakers (Nria- enide), the parrot-fishes (Searide), the surmullets (Mullide), the mogarras ((rerrida) and the soldier-fishes (Iolorentrid) occur. AL of these are good food fishes and of commercial importance. A pro- visional, but incomplete list of the Philippine market-fishes. giving the native, scientific, and English nanis will he found at the end of this article. | + Bagong is a general term applied to any small fish mixed with salt and partly dried. Bagong is most commonly eaten in the interior where fresh fish can not be obtained. FISHERY RESOURCES OF THE PHILIPPINES, 1. a1 THE MILKFISHES. Family Ohanidu. (PI. X.) The awa or milktish [Chanos chanos (Forskal) |, called buityos, bartgod, kawag-haway, and lumulocso by the Filipinos and bangellus by the Moros, is one of the most important commercial fishes in the Islands. It ranges over the entire group, from northern Luzon to Sitanki and is the most abundant fish in the Manila market. Frequently, during protracted rough weather it is the only variety obtainable. It is raised chiefly in the fish ponds at Malabon and at other places near Manila and therefore can be secured at any time regardless of the weather. This fish is particularly adapted to pond culture. being a vegetable feeder of rapid growth. The baityjos superficially resembles the mullet, but can easily be distinguished by the fact that the mullet has two fins on the back, while the baitjos has but one. The bays frequently reaches a length of 1.2 meters and then it is termed lumalocso. The eggs are deposited in the sea. The young appear during the months of April, May, June, and July and are called kaway-hawag. They are supplied with a yolk-sack which furnishes them with food until they are about 14 millimeters in length. At this age they are to he found in great numbers along ihe heaches of Zambales, Batangas, Mindoro, Marinduque, and doubtless in numerous other places. Here they are captured hy the natives and placed in Jarye earthen jars full of water called palyok. They are then conveved to the fish ponds. frequently a hundred miles distant. (Tig. 1.) One of the jars. pelyok, contains about 2,500 young bays. They sell for from 20 to 24 pesos per isung laesa (10.000); about six lacsa (60,000) are used to stock one pond of 1 hektare. As the fish grow they are thinned out by transfer to other ponds. Thirty-three per cent should reach marketable size. Four months after the transfer the bartjos should each be 25 centimeters in length. This size of fish retails for 9 centavos each; in 8 months the voung are each 40 centi- meters long and bring 20 centavos, while a vearling should measure half a meter and bring from 50 to 60 centavos. FISHEL PONDS.* Almost any kind of ground other than a sandy soil will do Tor a fish pond. It should be near salt water and not beyond the influence of the tide, as the bawyos thrive hest in brackish water. A complete system should have at least four ponds. These should be so constructed that one equals in area at least that of the other three combined. ?T am indebted to Mr. W. D. Carpenter of Malabon for most of the information regarding fish ponds. 20) SEALE. Usually the area of the Jarge pond is much greater. he dikes of the small ponds are low, often not 30 centimeters above the water level. These smaller ponds are of about equal size. being usually rectangular and each of about 200 square meters in area. The palaistaan are formed by throwing up dikes. The main dikes are large, especially along the banks of the so-called “river” or estero, where mangrove trees frequently are planted for their protection. The water from the estuary is per- mitted, when the tide is flowing, to enter once of the smaller ponds through a sluice (pirinza) usually constructed of masonry with two wates, one of several slides of solid wood for controlling the water and the other of close bamboo palings to prevent the egress of the baityas and the ingress of undesirable tenants such as carnivorous fishes and crabs which burrow into the dikes and cause leakage. Snakes and birds are also evils that have constantly to be guarded against. This small pond distributes the water supply to the others and is used for capturing the marketable bariyos. It is usually separated from the larger pond hy a close paling of bamboo around the narrow opening in the partition dike. When it is desired to capture the fish in the largest pond, the paling is removed and a strong current is caused to flow from the smaller pond to the larger. The batyos attracted by the fresh water swim against the current and enter the smaller pond in great numbers, where they are readily captured in a seine. This opera- tion is often accomplished about midnight, so that the fish will he exposed in the Manila markets in the best condition. The remaining two ponds, or subdivisions of the pond area inclosed within the limits of the boundary dikes, are connected with each other and with the pond which feeds the water by single pipes made of the hollow log of the luyong (Dlospyrus nigra Retz). These tubes are called palubunbuiyan, the water and fish being controlled at these openings by a solid wooden plug or a funnel of bamboo sirips. The water in these two small ponds is kept at a depth of but a few decimeters. the ponds being used interchangeably for cultivating the food alga (Oedogoninm) and for developing the hawagkawag. (Fig 2.) FOOD OF THE BANGOS. Tf it is desired to cultivate the food alga (the large pond is originally stocked in the same way). the water is allowed to drain off and the clay is exposed to the full power of the sun. The alga rapidly makes its appearance and a little water is then permitted to cover the bottom. This is gradually increased as the Oedogonium develops. The Oedogoninm sccms to thrive best wpon a clean clay (kaolin). Hf the bottom is covered with a deposit of dark mud and in old ponds where a black, evil-smelling deposit has formed, it is scraped clean with “QaLYOdSNVYUL SHV Add SHL HOIHM NI HOATVd YO SYVP 3HL ONY ‘ATINVS SIH HLIM GNOd HSId V SO NVIGUWND FHL “} ‘Old if §\ = % 9) ON ‘TIT (TOA “IOS ‘Nunor “ITH ] [SmoMnOSsay AYAHSIQD | TVaAS SEALE: FISHERY Resources.)

This operation is not necessarily done at any particular season, but whenever the condition demands it. The Ocdogonium is some- times purchased and placed in an exhausted pond. A small bancu load is worth one peso. A so-called “medicine” for the young fish (apparently used only in small ponds where the water is contaminated by close proximity to houses) is the Lemna minor Linn., the floating roots of which are greedily devoured. When the fry are to be planted in the pond, the water is again allowed to drain off and the alga is partially killed by the hot sun. This, it ix Claimed, renders the Oedogonium soft and fragile for the tiny mouths. Eventually, the young bajiyos are removed to the great pond where their quantity is largely governed by the supply of the food alga. The average value of the ponds about Manila Bay is probably 40 centavos per square meter, giving a total of more than 6,000,000 pesos for the pond value alone, which I am convinced is a conservative estimate. I chose one pond which measured 140 by 170 meters as an average of the twenty or more shown on a surveyor’s map compiled from data obtained from the owners of the properties. METHODS OF FISHING." It has been my privilege to wake personal observations of the methods employed in the fisheries of various parts of the world, in the Unite States, Alaska, New Zealand, Australia, Honolulu, and numerous Pacific Islands, also to some extent in Japan. Some time ago at the imstance of the Secretary of the Interior, Mr. Dean (. Worcester and before | assumed my position in the Bureau of Science, I made a more detailed examination of the methods employed in the fisherics of the eastern United States in order to secure the latest information regarding the various kinds of nets and apparatus that could with profit be used to develop the commercial fisheries of the Philippine Islands. It may not be out of place, therefore, to give brief descriptions of such apparatus as seems to me to he of expecial value and short sug- gestions as to its use. SEINES. In the Atlantic fisheries a great many more fish are caught with the various kinds of seines than in any other way. In 1904, the New York fisheries alone captured by this method 214,099,725 pounds of fish, with a value of 826,597 dollars, United States currency. *A full description as to detailed method of construction, size of twine, mesh, hanging of net and methods of using can be obtained by applying to the United States Division of Fisheries.
