Vol. 15, No-10 TUNA FISHING AT TAHITI By Wilvan G, Van Campen* In February of this year the U. S. Fish and Wildlife Service's vessel John R. Man- ning, operating from Pacific Oceanic Fishery Investigations' Honolulu base and fishing a series of tuna long-lining stations across the equatorial current system on 140° and 150° west longitude, put in at Papeete, Tahiti, for refueling. Some observations of the Tahitian tuna fishery were made with the primary objective of picking up any infor- mation on fishing methods which might be applicable elsewhere in the Pacific, particu- larly in those United States island possessions which need an augmented protein food supply or which are considered potential locations for tuna-cannery development. In this latter connection, interest in the Tahitian situation was heightened by the fact that on another recent POFI cruise some samples of tuna canned in Tahiti were obtained in the Marquesas, and it was anticipated that Tahiti might prove to be a model of an iso- lated tropical island with a small population and limited technical resources (i.e. like America Samoa) which was nevertheless able to keep a tuna cannery in operation (as Samoa has so notably not been able to do). It was found, in fact, that the Tahitian tuna fishery is quite primitive in nature, and that it has not proven capable of supporting even a modest canning industry in normal FIG. 1 - A TYPICAL TAHITIAN TUNA BOAT IN PAPEETE HARBOR.

The information obtained in the course of a brief stay at Papeete is necessarily incom- plete, and is derived more from interviews with local people than from first-hand obser- vation; however, it may be of some general interest in the absence of any more complete accounts, * TRANSLATOR, PACIFIC OCEANIC FISHERY INVESTIGATIONS, U. S. FISH AND WILDLIFE SERVICE, HONOLULU, T. H. 2 COMMERCIAL FISHERIES REVIEW Vol. 15, No, 10 The tunas commonly taken at Tahiti are the yellowfin (Neothunnus macropterus), called "thon" in French and "'a'ahi''in Tahitian, and the skipjack (Katsuwonus pelamis), called bonite in French and auhopu in Tahitian. No big-eyed tuna, albacore, or little tuna were Seen in the market, nor did the persons interviewed appear to recognize descriptions of these species. Some informants spoke of another kind of tuna called vato, apparently the dog-toothed tuna, which was said to be abundant around the reefs and passes of the Tuamotus, though less common around the high islands. The yel- lowfin and skipjack seen in the market and being unloaded from the fishing boats were of very mixed sizes, ranging from an estimated 5 pounds to about 50 or 60 pounds each in the case of yellowfin and to perhaps 40 pounds each for the skipjack. When the ob- server remarked on the unusually large size (by Hawaiian standards of comparison) of some of the skipjack, he was told that even larger ones--up to 70 pounds--were some- times brought in. Although this might be an exaggeration, it is interesting to note that a news story in the Pacific Fisherman of March 1950 contains a report of three-pole skipjack tuna (75 pounds) taken by a Hawaii-based vessel which fished in the Tahiti area, The Tahitian tuna boats are of uniform design, about 18 to 25 feet in length, and very much like small sport-fishing cruisers in general appearance, They are powered with 9 to 18 hp. Diesel engines of French manufacture. They carry no ice, Thecatch is kept on the floor of the small cockpit. Their only water supply is a bottle filled on the quay, and the only visible concession to comfort is a heap of dried leaves on the roof which is supposed to keep the cockpit cool, Each boat carries three fishermen, and there are said to be about 20 such boats at Tahiti, most of them based at Papeete. The boats are almost all owned by people ashore, and the proceeds are split 50-50 be- tween the owner and the fishermen, The operating radius of the fleet is about 30miles from Tahiti. The normal schedule is to put out to sea at around 8:00 a.m. andreturn at anywhere from 5:00 p.m. to midnight. The boats fish all around the island of Tahiti, often cross the 8-mile channel to Moorea, and sometimes go as far as the atoll of Tetiaroa, 25 miles north of Tahiti, where the fishermen sleep on the beach all night, The tuna schools are located by sighting the flocks of birds which accompany them, and the fishing is done with pole and line, using pearl-shell jigs of the traditional Poly- nesian type. The poles, of which four or five are carried lashed along the gunwales on FIG. 2 - TAHITI AN TUNA LURES.

They are perfectly plain, with no serving or wrapping on the grip. The line is slightly shorter than the pole. While fishing, the boat is kept under way and moving with the school at all times, and the pearl-shell jig is slapped and played on the surface in such a way as to attract the tuna. Live bait is never used, nor is there any spray or splash- ing of water over the lure. As in all islands where the Polynesian method of tuna fish- ing is used, it is believed that fine nuances of color in different shell hooks in relation to light conditions and to the color of the natural feed which the tuna are taking have an important effect on the success of the fishing. While ona school, the fishermenchange lures frequently in order to find the one which will be most attractive to the fish. Dif- ferences in color and sheen imperceptible to the unpracticed eye may give one hook a very high value while another apparently identical one will be considered almost worth- less, Pearl shells from certain islands, or from certain spots on the reefs of certain islands, are reputed to make especially effective hooks, October 1953 COMMERCIAL FISHERIES REVIEW 3 In addition to the jigging of fish from surface schools, large tuna and marlin are sometimes hand-lined from canoes at well-known ''tuna holes" ('apo'o a'ahi), some of whichare quite closeto the reef. Trolling appears to be completely unknown as a com- mercial fishing method, but occasionally when a boatis fishing a schooland large yellow- fintuna show up mixed with the smaller fishthey are taken onhand lines with cut bait. The seasons for tuna fishing at Tahiti are said to be January-March and July-Au- gust, but some fish are taken throughout the year. It was reported that the same sizes of fish are present in Tahitian waters at all times of the year, Unfortunately, the sea- sons of abundance of the tunas coincide with the peak seasons for the atule (big-eyed scad, Selar crumenophthalmus), which is generally preferred by the Tahitians. Thus, when big catches of atule and tuna come into the market at the same time, the tuna may be sold at give-away prices, or they may even have to be thrown away. No use ismade of refrigeration, nor'of salting or sun-drying, to preserve fish. The market closes at 7:00 p.m. and fish brought there after that hour are simply left to hang in very warm air temperature until the next morning. Fortunately there are remarkably few flies in Tahiti, but nevertheless much of the fish consumed around the island looks far from fresh, It may be because of this general staleness of the raw material that the Tahi- tians prepare most of their tuna or atule by marinating it in lime juice and salt andthen serving it in coconut cream, This is the staple fish dish, but large tuna are sometimes baked in the imu or earth oven, A good day's catch for a Tahitian tuna boat is said to be 20 to 30 40-pound fish, but from the writer's observations a proportionately larger number of 10- to 20-pound fish would be more usual, The fish are tied by the tails with leaves into bunches of 2 FIG. 3 - TAHITIAN FISHERMEN UNLOADING SMALL YELLOWFIN FROM THEIR BOAT AND HANGING THEM ON A SHOULDER= POLE FOR TRANSPORTATION TO THE MARKET. to 8 or 10, depending on the size, hung on a carrying pole, and shoulder-carried about 3 blocks from the quay to the market, At the public market (a concrete-floored, open- sided structure extending clear across one city block) the fish are hung up on iron rails and sold by the fishermen or their womenfolk, No scales are used to weigh the fish, They are sold individually for the most part. Smaller ones are sold by the bunch and the larger tuna are halved or quartered, Prices are arrived at by haggling at eachsale, and may vary considerably between the opening and closing of the market. A fair aver- 4 COMMERCIAL FISHERIES REVIEW Vol. 15, No. 10 age was quoted as 40 to 60 francs (65¢ to $1.00) for al0-pound tuna. The busiest time at the market is early Sunday morning, when the people who have come into town for Saturday nightare purchasing fish and other foodstuffs to take back to the country with them. Atsuch times the market is the scene of extremely spirited activity, and the guards are sometimes hard put to it to maintain order in the surging mob of compet- ing shoppers. Aside from such traffic-directing duties, the chief concern of the mar- ket attendants seem to be to see that all fish are hung off the floor on the iron rails provided for that purpose. A small cannery formerly packed tuna at Papeete, and this was the source of the samples obtained by POFI personnel in the Marquesas. The plant was established in 1939 in connection with a scheme for a pineapple industry, and when this fruit proved to be unsuited to Tahiti's humid climate, the facilities were converted to the proces- sing of yellowfin and skipjack tuna. The pack was put up in tall salmon cans, and most of it was canned in coconut oil, although some imported salad oil was used. The oper- ator uSed as much hand labor as possible, since labor is fairly cheap in Tahiti, and worked up to a capacity of about 2 tons per day and an output of 2 to 3 thousand cases per year. The average price paid for the fish ran around $80 a ton. No one connected with the enterprise seems to have had any experience in fish packing, and the product, which was not a solid pack, was probably rather crude and variable, but in the years immediately after World War II, when food of any sort was in short supply in Europe, the business prospered, Thebulkof the pack was always sent to France. Only asmall amount of skipjack in coconut oil was sold in French Oceania. With the return of normal market conditions in France, this unorthdox product be- came less saleable, and the cannery finally ceased operations in 1947, The machinery has been dismantled and stored, and has been up for sale for several years, The for- mer operator ascribes the failure of the enterprise to the irregular and unpredictable Supply of fish, the reluctance of jobbers to handle such a small number of cases, and the effects of unsettled world conditions and transportation difficulties on his supply of imported materials, chiefly tin plate. The story of tuna canning in Tahiti is in part merely a repetition of the same sad tale which has been heard from other Pacific islands where the development of a tuna industry has been tried--''no bait.'' Without the use of live bait, not enough fish could be taken out of the surface schools to keep the cannery supplied, and the local fisher- men lacked the knowledge and probably the capital to try long-lining. Vessels from Hawaii with experienced live-bait fishermen prospected in Tahitian waters, but were unable to find any adequate source of bait, Whether or not a tuna-canning industry can be supported by long-line fishing in the central Pacific is a question which must wait until someone makes the attempt, but the Tahitian experience seems to indicate that fishing the surface schools by the Polynesian method, without the advantage which live- bait confers, will not give enough return per unit of effort to produce a surplus of fish for canning, On the other hand, the existing tuna fishery at Tahiti is evidence of the fact thatan adequate supply of fresh tuna for an island population's needs can be obtained in the ancient Polynesian way even in the absence of a live-bait supply. Islands where the sup- ply of protein food is inadequate, where there are suitable stocks of tunas in nearby waters, and where the natives are willing to exert themselves to catch tuna and to eat them once they are caught, would appear to be promising locales for the introduction (or reintroduction) of this method of fishing. October 19535 COMMERCIAL FISHERIGS REVIEW 5 DEEP-WATER TRAWLING SURVEY OFF THE OREGON AND WASHINGTON COASTS (AUGUST 25-OCTOBER 3, 1952) By Dayton L. Alverson* SUMMARY A deep-trawling investigation off the Oregon and the Washington coasts was conducted by the Service's exploratory fishing vessel John N. Cobb from August 25 to October 3, 1952. The work was carried on in deep water adjacent to the pres— ent commercial fishing grounds of the local otter-trawl fleet. Exploratory fishing was confined between Cape Foulweather and Cape Lookout, Oregon, and between Cape Elizabeth and Destruction Island, Washington. A total of 48 otter-trawl drags were made at depths ranging from 100 to 400 fathoms. The continentel slope off the Oregon coast was found to be rather gentle, having a number of terreces, ridges, and hills. The bottom in this region is mostly free of obstructions and suitable for trawl fishing. Off the Washington coast the continental slope is quite steep, and a number of snags were encountered, Three commercially-utilized species of fish (Dover sole, sablefish, and Pacific ocean perch) dominated the catches. Dover sole and Pacific ocean perch were taken from depths between 100 and 240 fathoms. These two species were mixed in catches made off Cascade Head, Oregon. Sablefish were taken over the complete depth range fished; however, those in deep water were small and in poor shape. Other fish taken included varieties of red rockfish, arrowtoothed flounder, rex sole, slender sole, hake, and several types of skates. Trash fish such as hake and skates were taken in most drags, but they represented only a small por- tion of the total catch. OBJECTIVES OF EXPLORATION In a continuation of the program initiated in the summer of 1951, the U. S. Fish and Wildlife Service's exploratory fishing vessel John N. Cobb made a six- week deep-water trawl exploration off the coasts of Oregon and Washington during late summer and early fall of 1952. The objectives of this investigation were: (1) to ascertain the availability and the abundance of marine bottom fishes inthe deep waters adjacent to the present commercial fishing grounds of the localotter- trawl fleet; (2) to determine the commercial varieties of fishes inhabiting these deeper waters; (3) to gain information regarding technical problems involved in handling fishing gear in deep-water trawl work; and (4) to obtain catch informa- tion which would be of value in analyzing the practicability of commercial ex- ploitation of these regions. AREA EXPLORED Exploratory fishing was conducted off the coast of Oregon between latitudes 4L°2L7' N. and 45921' N. and off the coast of Washington between latitudes 47°22! N. and 47941' N, These areas roughly correspond to the waters between Cape Foul- weather and Cape Lookout, Oregon, and between Cape Elizabeth and Destruction Island, Washington.

October 1953 COMMERCIAL FISHERIES REVIEW 7 The area explored off the Oregon coast measured 34 miles north and south and extended nearly 40 miles offshore. The continental slopel/ in this region is relatively gentle, having an average gradient of about 2 percent (Shepard 1948). The width of the slope between the 100- and the 500-fathom contour lines varies between 20 and 30 miles, and a number of terraces, ridges, and hills exist along the gentle slope. Bottom samples from this region were predominantly mud; how- ever, gravel and rock were found in a few localized areas. The bottom dragged was mostly free of obstructions and suiteble for trawl work. The area explored off the Washington coast measured 19 miles north and south and extended 35 miles seaward. The slope characteristic in this region was some= what steeper, with the average width between the 100- and the 400-fathom contour lines being only 10 miles. Trawling bottom between 100 and 300 fathoms was poor and a number of snags were encountered. Below 300 fathoms a small terracedregion was located which was free of obstructions. Bottom samples showed mud with some stones or boulders. Several days were spent in an effort to locate favorable bottom on the offshore seamount discovered by the John N. Cobb in 1950 (Powell, Alverson, and Livingstone 1952); however, the fathograms showed only abrupt, steep slopes unsuitable for trawling. METHODS USED Commercial fishermen familiar with the trawl-fishing grounds along the Ore- gon and the Washington coasts assisted in laying out the desirable areas to be investigated. This procedure minimized the overlapping of areas to be explored with those already under exploitation by the otter-trawl fleet. The method of locating suitable trawling bottom was identical to that used in the John N. Cobb's 1951 trawl exploration (Alverson 1951). Navigation charts showing soundings were studied to learn the characteristics of the bottom topo- graphy. Regions which appeared to be satisfactory for dragging operations were sounded with a constant recording-type echo sounder, and if the resultant fatho- gram was relatively uniform a drag was made. Trawling methods used were similar to those commonly employed by the Pacific Northwest otter-trawl fleet. The net was set from the stern of the vessel and picked up on the starboard side. Catches were placed into deck bins of known cubic volume and the total weight of the fish was estimated from the occupied volume. Various conversion factors (volumes to weight) used for the several dom- inant species were obtained from data supplied by Seattle fish dealers, Drags were made for a period of one or two hours, depending on the depth and type of bottom. Generally the deeper drags were towed for two hours. Positions were determined from loran readings which were taken after the net had been set and again at the time hauling of the gear began. TYPE OF GEAR All exploratory drags were made with a standard 400-mesh Western traw12/ similar to the commercial trawl nets in use in the Facific Northwest. Ten 8-inch- diameter spherical aluminum floats were attached to the head rope of the trawl, 3 on each wing of the net, and 4 across the throat of the net. The 4 floats across the throat of the net were the "plane-type" with a lifting collar around 1 THE SLOPE LEADING FROM THE EDGE OF THE CONTINENTAL SHELF (APPROXIMATELY 100 FATHOMS ) TO THE GREATER DEPTHS OF THE OCEAN. 2/FOR DETAIL SPECIFICATIONS OF NET USED SEE COMMERCIAL FISHERIES REVIEW, VOL.

Recent tests by British investigators ( Anony- mous 1952) have shown this type of float to be greatly superior in its lifting ability as compared to other trawl floats of equal static bouyancy. RESULTS Detailed results of all exploratory drags have been tabulated and are pre- sented in table 1. These drags are diagrammatically illustrated in figures 1 and j ; ope wnich also include areas of special fisning interest, snags, and bottom con- tour lines. The positions given in the fishing log are the starting point of each drag, and the courses are the resultant direction between the starting point and the end of each drag.

Mad eae ee Three commercially-—utilized species - of fish-~Dover sole (Microstomus pacificus), sablefish (Anoplopoma fimbria), and Pacific ocean perch (Sebastodes alutus)--dominated the catches. Dover sole and Pacific ocean perch were taken infair quantities between 100 and 225 fathoms, while seblefish were taken somewhat deeper. The shaded areas shown on figures 1 and 2 indicate regions in which catches of the different species of 500 pounds per hour or greater were es taken. FIG. 3 - A CATCH OF BOTTOM FISH ABOUT TO BE DOVER SOLE: This species was taken RELEASED INTO THE DECK BIN. off the Oregon coast generally mixed with catches of Pacific ocean perch. The best catches of Dover sole were taken west of Cascade Head, Oregon, at depths from 200 to 242 fathoms. The bottom in this area was clear of obstructions and composed of gray mud. Fair catches were also made west of Siletz Bay, Oregon, in 120 to 122 fathoms. Samples of Dover sole taken from the area west of Cascade Head averaged 15 inches in length, with the sex ratio of males to females being approximately equal. For best Dover-sole catches see drags 13, 16-19, and 21 in the fishing log. SABLEFISH: These fish were taken in small quantities over the entire depth range fished; however, sablefish from depths below 250 fathoms were usually small and had a soft-flesh texture. Drag No. 10 in 300 to 304 fathoms, west of Cascade Head, Oregon, produced 1,000 pounds of sablefish, but only 65 percent of the fish were of marketable size. Fish taken from depths between 100 and 200 fathoms appeared in good shape and averaged from 7 to 9 pounds in weight. PACIFIC OCEAN PERCH: This species was found to be the most abundant fish taken during the 1952 deep-water trawl investigation. The best catches of Pacific ocean perch were made between 120 and 230 fathoms. Below 250 fathoms the fish was seldom taken. Good catches were made off the Oregon coast from Nestucca Bay 3/DRAG NUMBER 40, MADE ON THE OFFSHORE SEAMOUNT, |S NOT SHOWN ON THE CHARTS.

For best Pacific ocean perch catches see drags 13, 16-19, 21-23, 30 and 45. OTHER ROCKFISH: A number of other species of rockfish were found commonly associated with catches of Pacific ocean perch. These included the black-mouthed rockfish (Sebastodes crameri), the pop-eyed 7 rockfish (Sebastodes saxicola), the black- q throated rockfish (Sebastodes introniger), the rosy rockfish (Sebastodes rosaceus), the split-nosed rockfish (Sebastodesdiplo- : 5 pros), and the round-finned rockfish (Se- ao Fin ; se bastolobus alascanus).

An experimental vertical line trawl was fished sev- eral times at night--whiting and hake were caught, but no ocean perch. Efforts to tag ocean perch proved fruitless. Even the ocean perch brought to the surface from shallow depths of 35-40 fathoms were badly blown and unable to return ta the bottom. KOK OK OK Ok ZERO-AGE HADDOCK DISTRIBUTION STUDIED BY "ALBATROSS ID" (Cruise No. 54): A 13-day cruise to collect data to determine the distribution and numbers of zero-age haddock in connection with early life history and year-class strength studies was completed by the Service's research vessel Albatross II] at Woods Hole, Mass., on September 14. The area covered was Georges Bank and the Gulf of Maine. Zero-age haddock were found in a very limited area (South Channel and the Gulf of Maine) while yearling fish of other species were more widely dispersed. No young haddock were found off the bottom. Sixty-seven 20-minute tows with a No. 36 trawl were made throughout the area. One-hundred bathythermograph lowerings were made. In addition, at selected stations horizontal tows with a l-meter ring net attached to the towing warp were made. Further analysis of the distribution of zero-age haddock will have to await the com- pletion ofa similar sampling of the Southern New England Banks. North Pacific Exploratory Fishery Program SALMON RESOURCES ADJACENT TO ALEUTIAN ISLANDS INVESTIGATED BY "JOHN N. COBB" (Cruise No. 16): An investigation of the salmon resources in the off- shore waters adjacent to the 1e Aleutian Islands, Alaska, was conducted by the John N. Cobb on an extended cruise which was completed on August 8. The vessel, one of the Service's exploratory fishing vessels, sailed from Seattle on May 18. The investigation was part. of the preliminary salmon research by the Service in connection with the International Convention for the High Seas Fisheries of the North Pacific Ocean, Objectives were to gain as much knowledge as possible concerning salm- on in offshore waters, and to test and evaluate the effectiveness of various types of fish- ing gear for catching salmon on the high seas. Since it was necessary to obtain samples of salmon from as large an area as possible, the John N. Cobb changed fishing locations frequently. Gill nets, trolling gear, floating long lines, and a trap were fished, but only the gill nets proved successful as a means of catching salmon. The gill nets used were 100 October 1953 COMMERCIAL FISHERIES REVIEW 39 fathoms to a shackle, 75 meshes deep, and made of 54-inch (stretched mesh) linennet- ting. Asa rule, either 5 or 10 shackles were fastened together and set as a string. Fishing operations commenced on June 9 and ended on July 28. From June 9 to July 17 the vessel operated in the Pacific Ocean from Unalaska Island to near Agattu Island at distances from 15 to 60 miles offshore. From July 17 to July 28 operations were carried on in the Bering Sea from Umnak Island to Kiska Island at distances from 5 to 45 «niles offshore. During the trip approximately 1,200 salmon were taken and frozen for additional study in the Service's Seattle laboratory. Catches of salmon varied considerably in individual gill-net sets, ranging from 0 to 18 per 100-fathom shackle in Pacific Ocean sets, and from 1 to 28 in Bering Sea sets. Salmon catches consisted of 32 percent red, 3 percent silver, 26 percent pink, and 39 percent chum salmon in the Pacific Ocean fishing; and 2 percent red, 1 percent silver, 3 percent pink, and 94 percent chum in the Bering Sea fishing. Weights, measurements, and other information concerning the salmon caught will be determined from the samples brought to Seattle. This exploration was carried out as a joint operation by the Service's Branch of Commercial Fisheries and the Branch of Fishery Biology. A biologist from the Fish- eries Research Institute at the University of Washington also accompanied the vessel. Ohio's Lake Erie Commercial Fisheries Production, 1952 The total catch of fresh-water fish by Ohio's commercial fisheries of Lake Erie amounted to 21, 246,640 pounds in 1952, a 14 percent increase over the 18, 700,118 pounds landed in 1951, reports a recent bulletin from the Ohio Department of Natural Resources (see table). This increase was due mainly to the large rise in blue pike landings and lesser increases in landings of carp and catfish.

MANNING” (Cruise No. 16): Evidence of an unexploited and potentially valuable com- mercial tuna resource close to the Hawaiian Islands was gathered by the research ves- sel John R. Manning on a 6-week cruise completed at Kauai on August 31. The vessel, operated by the Service's Pacific Oceanic Fishery Investigations (POFI), caught over 200 yellowfin tuna (about 10,000 pounds) by a small amount of experimental long-line fishing gear in only 5 days of fishing. The vessel operated along the 155th and 160th meridians in the equatorial region south of Hawaii. Remarkably good fishing for yel- lowfin tuna was found between 2 and 4 degrees north of the equator on 155° W. longi- tude, and in the vicinity of Christmas Island. A number of albacore were also taken and this species would undoubtedly be a profitable secondary product of a yellowfinfish- ery in those waters. Several promising innovations in tuna long-line gear were tested during the cruise with the object of developing a type of line more efficient than that now used by Hawaiian and Japanese fishermen. These experiments included the substitution of hemp for the usual more expensive cotton line, variations in the spacing of the hooks along the main line, and a new method of attaching the branch lines to the main line designed to reduce tangling. It was found that tangling, ordinarily a time-consuming and troublesome feature of long-line fishing, can be virtually eliminated, and it is thought that the new method will enable fishermen to operate more gear and catch more tuna. The results of the hook-spacing experiments indicate that the most efficient arrangement is approx- imately 10 hooks to each 1,000 feet of main line. Twelve stations were fished on 155° between 10° N. and 4° S. latitude. In addi- tion, 3 stations were fished between 155° and the vicinity of Christmas Island. Ateach of these stations 50 to 60 baskets of long-line gear were fished, of which 30 had 6 hooks per basket of gear; and varying numbers (usually 20 and 10) of the baskets had 11 and 21 hooks, respectively. The best fishing occurred between 2° and 4° N. latitude inthe oceanic areas, and in the vicinity of Christmas Island. The 5 consecutive stations within these limits yielded the following catches of yellowfin: six-hook baskets 11 per hundred hooks, 0.6 fish per basket; 11-hook gear, 9 per hundred hooks, 0.7 per bas- ket; 21-hook baskets, 9 per hundred hooks, 1.8 per basket. The catches of the 21-hook gear are, however, not comparable to the catches on the other gear as the experiment- al design of this preliminary trial does not permit direct comparison. These catches indicate a very marked concentration of yellowfin tuna, a concentration that should support a United States fishery. Fishing was not spectacular along 160° between 3° S. and 9° N. latitude. As on 1550, the best fishing occurred in the south equatorial current north of the Equator. The catches of the 3 types of gear mentioned indicate that the 11-hook baskets are more efficient than the 6-hook baskets. Because of the increased hauling time of the 21-hook gear, this type does not appear suitable for commercial use. A swiveling ar- rangement that virtually eliminates time and energy-consuming tangles was givena thorough test on this cruise. Its eminent success indicates an improvement that should permit a crew to fish more gear per day, improving the prospects for United States ex- ploitation of the resource. ; Three baskets of gear made of factory-tarred Italian hemp line were fished each day. Towards the end of the cruise this gear became too slick to be pulled with the Japanese line hauler, indicating it is not a suitable material for this type of line fishing. Scientific findings of the expedition included the capture of a variety of mackerel shark hitherto known only from the Atlantic, and the discovery of evidence that yellowfin tuna were actively spawning in the area where the best fishing was found. The scien- tists collected samples of scales and vertebrae from over 400 tuna, and will attempt to read the annual rings in these specimens in order to gain information on the age and growth rate of the fish. October 1953 COMMERCIAL FISHERIES REVIEW 41 Several days were spent at Christmas Island exploring possible sites for the in- stallation of devices to automatically record seasonal changes in the temperature of the ocean around the island, which lies in the heart of the rich equatorial fishing grounds. The results of this reconnaissance will be used in planning the possible fu- ture establishment of a small field station on Christmas Island. The seven tons of yellowfin and albacore landed by the John R. nning were de- livered to a Kauai cannery for processing. POFI scientists will on a constant check on these fish as they pass through the cannery in order to evaluate their quality in comparison with tuna from Hawaii and West Coast fishing grounds. KOK KOK "CHARLES H. GILBERT" SCOUTS FOR TUNA IN HAWAIIAN WATERS (Cruise 11); Quantitative scouting for surface schools of skipjack and other tuna in Hawaiian waters was carried out by the Charles H. Gilbert, a research vessel of the Service's Pacifie Oceanic Fishery Investigations (POFI) on a 34-day cruise completed at Hono- lulu on April 30. The vessel also executed weekly hydrographic sections on a line run- ning north and south between Oahu and Molokai. A systematic scouting for surface schools of skipjack and other tunas was carried out in Area I north of Oahu and in Area II south of Oahu. A total of 47 bird flocks were sighted in Area I, a scouting distance of 360 miles, whileinArea II 58 flocks were seen in 720 miles of scouting. Several of the schools attended by bird flocks were investi- gated by means of actual live-bait fishing and surface trolling in order to determine the kind of fish schools, the sizes of fish in the schools, and the approximate size of the schools. A few good traces of fish schools were obtained on a depth recorder. OK OK OK SKIP JACK TUNA CONCENTRATIONS DISCOVERED OFF HAWAIIAN ISLANDS BY "CHARLES H. GILBERT" (Cruise 13): Many large schools of skipjack or striped tuna (aku) were observed concentrated in areas both to the north and south of the Hawaiian Islands by the Charles H. Gilbert on a 38-day cruise completed at Honolulu July 12. Following a regular search pattern designed to furnish data for estimat- ing the quantities of tuna present in the vicinity of the islands, the ves- sel encountered more skipjack schools per unit of area north of the Islands than immediately to the south - of them, with an especially heavy concentration of fish extending east and west of a point some 50 miles ‘ Gs northeast of Oahu. Farther to the \ SKIPJACK TUNA south, however, two other widely separated areas of tuna abundance were found at 100 and 200 miles south of Honolulu. All of these concentrations were outside the area regularly fished by the local sampan fleet. Se In contrast, very little activity was noticed in inshore areas to the south of the is- lands, with a notable scarcity of fish schools south of Molokai and Lanai. Generally, the greater numbers of schools were sighted on the scouting runs made in thé east to west direction, with lesser numbers on the west to east runs, the latter being caused by less favorable scouting conditions when running upwind or possibly because ‘of the easterly movement of the tuna schools. The north-south runs showed no significant differences in the number of sightings with the direction of the vessel. A part of this cruise was devoted to the testing of chemical and visual attractants at sea, using various combinations of tuna extract and artificial bait on skipjack schools. The tuna extract alone failed to obtain any noticeable response from the skipjack, which appeared to be neither attracted nor repelled by it. Artificial bait of various kinds such 42 COMMERCIAL FISHERIES REVIEW Vol. 15, No. 10 as cellophane strips, tin-foil squares, aluminum-foil strips, and tin strips were tried as possible visual attractants of skipjack. These materials were chummed alone or together with extract. Shiny materials, such as tin-foil squares and tin strips attract- ed the fish momentarily, in some cases even getting the fish away from feeding on the remaining live bait (chumming with live bait was stopped just before chumming with artificial bait). The momentary response was probably caused by the resemblance of the glittering material to live bait, but the fish were seen to turn away from the mate- rial after approaching it once. Stomachs were examined of the fish which were caught from the school on which tin strips were tested, and in 2 out of 17 stomachs, 1 strip apiece was found. Chumming of dead bait (nehu) from the forward well deck occasionally brought re- sponse from the fish, which followed the bait as it sank. The skipjack soon returned to the surface when live-bait was chummed. No noticeable response was obtained with calcium carbide pellets, which effer- vesced as they slowly sank. In all cases the fish soon departed from the vessel andhad to be rechummed with live bait before further tests could be carried out on them. Three weekly hydrographic sections were executed in Kaiwi Channel as a continua- tion of the survey started during Cruise 11 of the Charles H. Gilbert and carried through during Cruise 12. Completion of this cruise marks the end of the third month of weekly scouting trips in a research program planned by the Service's Pacific Oceanic Fishery Investigations and the Territory Division of Fish and Game to supply information for the ultimate ex- pansion of the local tuna fishery. The program will be continued by the Hugh M. Smith. The cruises of the Charles H. Gilbert have involved, in addition to fish scouting, week- ly investigations of the physical and chemical changes in the sea water which might be related to tuna abundance. KOK kok ok "CHARLES H. GILBERT" SCOUTS FOR TUNA BETWEEN HAWAII AND WEST COAST (Cruise 14): In conjunction with returning the Charles H. Gilbertto the main- land for alterations, observations were made of surface fish schools between Hawaiiand the West Coast. Trolling gear was used daily and water temperature data were collected with a bathythermograph and continuous recording thermometer. The vessel departed from Honolulu on July 16, and arrived at San Francisco on July 26. Very few scattered birds were seen in the offshore area (50 miles from land) be- tween Honolulu and San Francisco. These were mainly black-footed albatrosses, noted followers of ships. During the five hours of daylight after leaving Honolulu, only three bird flocks (all with tuna schools) were observed. No tuna were caught during the ten days of trolling. Three mahimahi (C. hippurus) were caught, the last at 32° N. latitude on 135° W. longitude. The small catch may be partially attributed to the speed of the vessel (average for trip 9 knots) which was con- siderably above the optimum trolling speed of 6 to 63 knots. The continuous recording thermograph indicated the passing of about 4to6 "fronts." Two, and possibly three, were located in the area between 25°30! N. to 26°30! N. lati- tude on 147° W. to 145° W. longitude. Generally the cruise was handicapped by moderately rough seas and complete over- cast on 7 of the 93 days, limiting the range of visibility. The Charles H. Gilbert will be at a California shipyard for the balance of 1953. OK OK OK Ok HYDROGRAPHIC AND BIOLOGICAL DATA AROUND HAWATIAN ISLANDS COL- LECTED BY "HUGH M. SMITH" (Cruise 21): A 2,500-mile, 69-station hydrographic cruise, part of the Service's Pacific Oceanic Fishery Investigations' program to study October 1953 COMMERCIAL FISHERIES REVIEW 43 conditions governing the Hawaiian skipjack tuna fishery, was completed on August 26 by the Service's research vessel Hugh M. Smith. Oceanographic and biological in- vestigations were carried on in an area of 86,000 square miles surrounding the Ha- waiian Islands; data were collected which will help to determine seasonal changes in local waters and aid in explaining fluctuations in the local skipjack catch. Surface trolling and the direct observation of fish schools were also carried out, and ina further effort to aid the skipjack (aku) fishing fleet, reports of fish sightings were broadcast twice daily by short-wave radio. The goal of this POFI program is to obtain sufficient understanding of the habits of the skipjack tuna and the oceanographic conditions influencing their distribution to permit expansion of the present localized and highly seasonal fishery. States Get Over $4 Million Federal Aid for Fish Restoration An upsurge in the purchase of sport fishing equipment during fiscal year 1953 (ending June 30), attributed in part to the growing popularity of spinning tackle, has made the sum of $4, 299,916 in Federal Aid funds available for apportionment to the 48 states for sport fishery restoration projects during fiscal year 1954, the Secretary of the Interior announced recently. This is an increase of $1,791, 389 over last year's apportionment of $2,508, 527. These Federal funds become available to the states under the terms of the Federal Aid in Fish Restoration Act of August 9, 1950, better known as the ''Dingell-Johnson Act."' This program, now in its third year of operation, is enabling the states tocreate new public fishing lakes, restore many unproductive waters, and put research findings to better use. The revenue for the program comes from the 10 percent excise tax on fishing rods, creels, reels, and artificial lures, baits, and flies, paid by the manufacturers of those products. Collections from this source during the year ended June 30, 1953, totaled $4,556,615. From this total is taken the annual apportionments of $75, 000 to Alaska, $25, 000 to Hawaii, and $10,000 each to the Virgin Islands and Puerto Rico, and the cost of administering the act by the U. S. Fish and Wildlife Service. To provide a fair distribution of Federal funds, each state's share is based on the relation of the number of its fishing license holders to the total in all States, and the ratio of each state's area (including coastal and Great Lakes waters) to the area of the entire country. The Act also states ''that no State can receive less than one percent nor more than five percent of the total apportioned to all States.'' This provision allows the small States enough working capital to finance comparatively big projects, while the large States will be able to receive only the maximum amount. On this basis California, Michigan, and Minnesota are given the maximum apportionment of $214, 996 each, while Connecticut, Delaware, Louisiana, Maryland, Massachusetts, New Hampshire, New Jersey, Rhode Island, and Vermont will receive the minimum of $42, 999. To obtain the benefits of the Federal grants, the states submit project proposals to the Fish and Wildlife Service. Acting for the Secretary of the Interior, the Service re- views these proposals to learn whether they are substantial in character and design, within the meaning of the Act. When a project is approved, the State game and fish de- partments proceed to carry out the plans, spending their own funds. The states then submit reimbursement claims for 75 percent of the costs of the project, either period- ically or at the completion of the work. The remaining 25 percent of project expendi- tures is financed out of regular state funds. All equipment, lands, and structures be- come the property of the states. All project workers are hired by the states and are state employees. Apportionments to the 48 states for fiscal year 1954 are as follows: 44 COMMERCIAL FISHERIES REVIEW Vol. 15, No. 10 Alabama......... $52,945|Maine ..........

S.-Japanese Fishing Operations The U. S. Customs laws regarding landings of fishery products from joint U. S. - Japanese fishing operations were outlined by the Bureau of Customs in a recent letter to the State Department. The letter comments as follows: "Reference is made to your memorandum... You ask for the comments of this Bureau with respect to certain of the questions raised. ..the Bureau's comments thereon are as follows: "1, Under what conditions can processed fishery products, such as canned crab meat, be landed at an American port if this product has been caught and processed by a United States-Japanese joint fishing company incorporated in accordance with United States laws and regulations? Catcher boats (Japanese) and the mothership (American) would be under United States registry if per- mitted by United States regulations. "Section 251, title 46, United States Code, restricts the American fisheries to ves- sels of the United States properly documented to engage in that trade. A vessel which is engaged in the catching of fish is engaged in the fisheries. Such a vessel also is en- gaged in the fisheries when it transports its catch to shore. In addition, where one ves- sel is used to catch the fish and another is used to transport the catch to shore, both vessels are engaged in the fisheries so long as both are under the same ownership or under the same complete control and management. "The Bureau assumes, and will so treat the subject, that (1) it is intended that the operations of catching, processing, and transportation to port of fish products thereof are to be conducted by means of vessels which, if not under the same ownership, areto be under the same complete control and management, i.e., the said United States-Jap- anese joint fishing company, and (2) the mothership is to be so documented under the laws of the United States as to entitle it to engage in fishing. The latter would require the further assumption that the company is a citizen of the United States as defined in the documentation laws. "Catcher boats of foreign build or ownership are not entitled to be documented for the American fisheries nor may any undocumented vessel engage in the American fish- ery except one of less than 5 net tons which is owned in the United States, or as here- after stated in this paragraph. The catch of vessels of foreign build, flag, or ownership, except as hereafter stated in this paragraph, will not be regarded as products of an American fishery entitled to free entry under paragraph 1730 (a), Tariff Act of 1930, as amended. The employment by an American fishery of citizens of a foreign country who use their own foreign undocumented catcher vessels does not preclude free entry of their catches under paragraph 1730 (a), supra. October 1953 COMMERCIAL FISHERIES REVIEW 45 "If catcher boats built in the United States and owned by a citizen of the United States, as defined in section 802, title 46, United States Code, which may include a corporation organized and existing under the laws of the United States or of a State thereof, the president and managing directors of which are citizens and of which at least a controlling interest is vested in American citizens free fromtrust or fiduciary obligation in favor of alien interests, are documented under the United States flag, they will be entitled as vessels of the United States to engage in fishing and to land their catches or products thereof at a United States port as products of an American fishery entitled to free entry under the provisions of paragraph 1730 (a), Tariff Act of 1930, as amended. Further, the United States-flag mothership will be entitled to transship from the high seas such catches or the products processed therefrom at sea to a port of the United States as products of an American fishery likewise entitled to free entry. "2. Is the entry of products caught and processed at sea by such enter- prise subject to prohibition, restrictions, or import duties at the United States port? These products would be transported from the fishing ground to a United States port by the United States registered carrier. "The tariff status of fish not entitled to free entry as products of an American fish- ery may be dutiable or entitled to free entry depending upon the type of fish and the pro- cessing to which it has been subjected. For instance, tuna fish, fresh or frozen, is en- titled to free entry under the provisions of paragraph 1756, Tariff Act of 1930, while tuna, packed in air-tight containers (canned, not in oil), and tuna packed in aiill (canned), are dutiable under paragraphs 718 (b) and 718 (a), respectively. Crab meat, including crab paste and crab sauce, packed in air- tight containers, is dutiable at the rate of 223 per centum ad valorem under the provisions of paragraph 721 (a), Tariff Act of 1930. "No quota is in effect at this time on crabs or tuna fish or canned products thereof. Groundfish, namely, cod, haddock, hake, pollock, cusk, and rosefish, excepting such as are entitled to free entry as products of an American fishery, are subject upon en- try to tariff rate quotas."' Wholesale Prices, August 1953 WHOLESALE PRICES, AUGUST 1953: Continued light production of edible fishery products caused wholesale prices to again rise from July to August. The over-all edi- ble fish and shellfish (fresh, frozen, and canned) wholesale index for August was 107.8 percent of the 1947-49 average (see table)--5.1 percent higher than in July and 8.0 per- cent above August 1952, the Bureau of Labor Statis- =—_ tics of the Department ‘of Labor reports. FRESH FISH an SHELLFISH es August prices for all varieties in the drawn, dressed, or whole finfish subgroup were higher than a month earlier, except western halibut and yellow pike at New York City which were lower. The larg- est increase (64.9 percent) was for large drawn off- shore haddock at Boston where continued light land- ings caused ex-vessel prices to rise. The largest price drop (8.3 percent) was for western halibut at New York City because the supply was liberal. Com- pared with August 1952, all items under this sub- group were priced higher this August except western halibut at New York and lake trout at Chicago which were quoted lower. The drawn, dressed, or whole finfish index for August was 19.9 percent higher than the previous month and 19 percent higher than in August 1952. Prices in August for fresh processed fish and shellfish were down 2.1 percent prin- cipally due to a 12. 7-percent drop in shrimp prices at New York City because shrimp 46 COMMERCIAL FISHERIES REVIEW Vol. 15, No. 10 supplies had improved considerably. Offsetting the drop in shrimp prices, smallhad- dock fillet prices at Boston were up 25.4 percent over a month earlier and 32.7 per- Table 1 - Wholesale Average Prices and Revised Indexes for Edible Fish and Shellfish, August 1953 and Comparisons Group, Subgroup, Point of al al/ ] and Item Specification Pricing |Unit FISH AND SHELLFISH (Fresh, Frozen Fresh and Frozen Fishery Products: Drawn, Dressed, or Whole Finfish: ° Haddock, large, offshore, drawn, fresh seocccce Halibut, Western, 20/80 lbs., dressed, fresh or fTOZEN coc-ccoccccccccccrcceccecccce Salmon, king, lge. & med., dressed, fresh or FLOZON coccccccccsccccccccccocccccccccorcccce Whitefish, mostly Lake Superior, drawn (dressed); fresh) u refrigeration experts, aN SS 2 —— Tlie LET representatives of the “NANG ol sa eae Si) fish industry, and oth- aoe a ers interested incold a ne 2 : SCALE MODEL OF PREFABRICATED COLD-STORAGE WAREHOUSE. Wi storage. The construction of the warehouse is simplified by covering the roof with continuous aluminum sheeting, secured by clip-on rolls. It is claimed that this method eliminated horizontal joins and consequent leakage. It was also claimed that the high cost of manual labor in loading and unloading-- (a serious economic problem to all large-scale cold-storage operators)-- was greatly reduced in the new prefabricated design by its clear, pillarless working space, some 18 ft. high, in which it is possible to operate an electric pallet-stacking truck handling large quantities of goods with only one operator. At the same time, the high volume- 62 COMMERCIAL FISHERIES REVIEW Vol. 15, No. 10 to-area of insulation ratio reduced capital cost and the power consumption of the re- frigeration plant; while because of the design of the warehouse the refrigeration plant itself necessitated less cost. The storage plant costs £30,000 (US$84, 000) without the refrigeration plant, and is to be supplied--with its own engineroom and reception bay--in standard parts, ready for quick and simple erection. The inside dimensions of the smallest unit are 65 x 62 x 18 feet, providing 73,000 cubic feet of storage space. Larger units with a clear span of up to 200 feet, by any length, will be supplied. The engineroom section can be made larger to hold other processing equipment. Another model was shown also. This is a pipe-frame cold-storage warehouse and smaller than the other type described above. In this unit no structural steel is used, the building frame being made from standard refrigeration pipes. This design is not yet commercially available, but it is proposed to make it available in the form of standard truss sections (20, 30, or 40 feet wide) to be assembled in units to form plants of varying widths and lengths. Insulation will be provided by standardized in- sulation blocks to form an envelope over the building. Besides saving labor, this warehouse is estimated to save 60 percent in capital cost. Also on show was an insulated transit container, described as the cheapest and lightest made, and suitable for shipping frozen fish. The medium size (13 cubic feet) weighs only 32 pounds. The container is very durable, and its cost ranges from £5 10s.(US$15. 40) for the 1-cubic foot size to L9 10s. (US$26.60) for the 24-cubic foot size. % OK OK OF OK UNDERWATER TELEVISION CAMERA VIEWS SEA BOTTOM: Trials with under- water television have provided new information about the sea floor, says the British Institute of Oceanography, giving details on equipment developed by the Admiralty on the Royal Research ship DiscoveryIl. The trials show that the technique could develop into a valuable oceanographical instrument, especially if used in conjunction with other gear, reports the July 25 issue of the Fishing News, a British trade magazine. The camera was first installed on the Discovery Il last summer. A modified TV receiver was used as the main monitor, and pictures displayed on the camera control- unit monitor were photographed when required by a camera attached to the unit. The unit in its present form is cumbersome, however, and its scope is limited by its weight, making it unsafe to use except in calm water, and difficult to lower to any great depth. But these objections are likely to be overcome. So far the television has been most successful in views of the sea bottom, andthe Institute regards the pictures taken as of permanent value. Shoals of fish have been seen on several occasions; also plankton organism--these mostly as spots of light, though occasionally the type of organism could be identified. Observations on the sea bottom were made in about 33 fathoms off Falmouth, in 60 fathoms near the mouth of the English Channel, and in about 80 fathoms near the edge of the continental slope; also off Portugal on the Gettysburg Bank, and on the rocky sea bottom around the Azores. % OOK OK OK Ok RUSSIA ORDERS TRAWLERS: Orders for the building of fishing trawlers for Rus- sia have been received by two British firms--one in Aberdeen and the other in Lowes- toft, reports the August 29 issue of The Fishing News, a British trade magazine. The proposed orders are under consideration by the Board of Trade, said an official of the Board "because it is always a feasible argument that fishing trawlers could be con- verted to minesweepers." October 1953 COMMERCIAL FISHERIES REVIEW 63 This statement followed questions sent to the President of the Board of Trade by a member of Parliament who said he was told by the Aberdeen Trades and Labour Council that the Russian Government had made approaches ''to a number of British shipbuilding firms with a view to placing large orders for building trawlers and fish factoryships.'' He asked whether it was true that difficulties had been placed in the way of acceptance. He urged the Minister to take steps to remove such difficulties "in the interests of international trade and employment in British shipbuilding yards." Later information indicates that 40 trawlers and fish factoryships worth about E8, 000, 000 (US$22, 400,000) are involved. Russia needs these vessels to develop its fishing industry. A British Admiralty committee is considering whether the vessels could be converted into minesweepers; the availability of steel; and effect of the or- ders on other vital shipbuilding. KOK KK OK SCOTTISH PORT TO TRAIN FISH WORKERS: The Aberdeen and North-East Re- gional Advisory Council for Technical Education and Aberdeen's fishing industry have completed plans for training young men and women in the fishery products distribu- tion field. The courses will start in September with a class of 20, functioning under the local authority, reports the July 25 issue of The Fishing News, a British trade magazine. Employers will release the students from their work on two afternoons each week. One of the afternoons will be given over to theoretical work, and the other to practi- cal. The curriculum will include such subjects as hygiene, background knowledge of the industry, fresh fish preparation and packing for distribution by rail and road, curing and other processing methods, and work of the Torry Research Station on the preservation of fish.

C., and was announced in the September 18 Federal Register. The hearing was called by the Secretary of Health, Education, and Welfare, and held for the purpose of receiving evidence on proposals of the Pacific Coast Oyster Growers Association to a- mend the standards of identity for Pacific oysters. Evidence was restricted to testi- mony and exhibits relevant and material to the proposals. The proposals would amend Sections 36.17 to 36.20, inclusive, of the regulations, which fixed and established definitions and standards of identity for raw Pacific oysters. As amended the section would provide that: 1. Large Pacific oysters, large raw Pacific oysters, large shucked Pacific oysters, are of the species Ostrea gigas and conform to the defini- tions and standards of identity prescribed for oysters by Sections36. 10 and are of such size that 1 gallon contains not more than 64 oysters, and the largest oyster in the container is not more than twice the weight of the small- est oyster therein. 2. Medium Pacific oysters... and are of such size that 1 gallon con- tains more than 64 oysters and not more than 96 oysters, and the largest oys- ter in the container is not more than twice the weight of the smallest oyster therein. 3. Small Pacific oysters... and are of such size that 1 gallon con- tains more than 96 oysters and not more than 144 oysters, and the largest oyster in the container is not more than twice the weight of the smallest oyster therein. 4. Extra small Pacific oysters... and are of such size that 1 gallon contains more than 144 oysters, and the largest oyster in the container is not more than twice the weight of the smallest oyster therein. The proposed amendments for consideration at the hearing are subject to adoption, rejection, or modification by the Secretary of Health, Education, and Welfare, in whole or in part, as the evidence adduced at the hearing may require.

Miller, article, pp. 75-77. (From The Progressive Fish Culturist, vol. 15, no. 2, April 1953, processed, annual subscrip— tion $1.25 domestic, US$1.65 foreign.) Describes toration became a reality with the passage by Con— gress and approval by the President of the Federal Aid in Fish Restoration Act, August 9, 1950 (64 Stat. 430). The achievement of this goal was the result of many years of effort and planning on the part of conservationists who envisioned a program the commercial fishery of the Alabama portion of the Tennessee River; early post—impoundment fishing, 1936-45; later post-impoundment fish- ing, 1945-52; rebirth of the mussel industry; and discusses the present trends in relationto the sport fishery. Statistical data show the commercial fish catch for Guntersville, Wheeler, Wilson, and Pickwick Reservoirs from 1943 to 1952. Also includes statistical data on the annual harvest of mussel shells in north Ala-— bama Tennessee Valley reservoirs for the years 1945 to 1951. Dingel]l-—Johnson Quarterly (For the Period July 1, 1951, to June 30, 1952), vol..1, July 1953, 79 Pe, processed. This is the first of a series designed to benefit sport fishing in the same way that the Pittman-Robertson program has benefited wildlife restoration. In substance, the above Act makes the 10—percent Federal excise tax collected on sport-fishing equipment available for apportion— ment to the states and territories annually under the general administration of the U. S. Fish and Wildlife Service. The states are responsible for the selection, design, and execution of projects, and expend their own funds for project operation. Upon presenting evidence of satisfactory progress or campletion, the state is reimbursed to a maxi- mum of 75 percent of costs incurred. Federal Aid in Fish Restoration is designed to supplement rath— er than supplant the usual state sport-fisheries program. of publications reporting on the Federal Aid in Fish Restoration program which is designed to help the states solve their sport-fishery prob- lems. Achievements of general interest are pre-— sented for the first year of the program from investigations, development, and land and water acquisition projects. Federal Aid in Fish Res- Fishery Statistics of the United States 1950, by A.W. Anderson and C. E, Peterson, Statistical Digest 27, 492 pe, illus., printed, $2.00, 1953. Fish and Wildlife Service, U. S. Department of the In— terior, Washington, D.C. (For sale by the Su- perintendent of Documents, Washington 25, D. Ce) COMMERCIAL FISHERIES REVIEW THE FOLLOWING SERVICE PUBLICATIONS ARE FOR SALE AND ARE AVAIL= ABLE ONLY FROM THE SUPERINTENDENT OF DOCUMENTS, WASHINGTON 25, D. C. Presents the results of the first complete sta— tistical survey made of the United States and Alaska fishery industry since 1931. Previous complete surveys of the U. S. fisheries were made only in 1908 and 1931. In recent years canvasses of the fisheries of most sections of the country were made annually. However, no data on the fisheries of the Mississippi River area were assembled since 1931, and since 1940 ‘only partial surveys were made of the fisheries of the Great Lakes, South Atlantic, and Gulf States. This sourcebook is the latest in a se- ries of annual statistical reports which contain data on the catch of fishery products and its value, employment in the fisheries, quantity of gear operated, and the number of fishing craft employed in the capture of fishery products. Information on the quantity and value of the pro— duction of manufactured fishery products and by- products is also shown. For the first time since 1945, data on the catch and operating units by counties are shown for the entire Atlantic and Gulf coastal areas, except Maryland. Where a-— vailable, summary information from 1880--when the first comprehensive statistical survey of the fisheries and fishery industries of the Unit— ed States was made—to date is included. Out— standing developments during 1950 were the re- cord landings of tuna and tuna-like fishes; the continued high production of menhaden; and the expansion of the shrimp fishery in the Gulf area. A total of 161,463 fishermen, 11,496 vessels of 5 net tons capacity or greater, and 80,814 boats were employed in the commercial fisheries of the United States and Alaska in 1950. During this year the catch of fishery products in all sec— tions of the United States and Alaska totaled 4,,884,909,000 pounds, valued at $343,876,000 to the fishermen. This was an increase of 2 per— cent in quantity and 1 percent in value compared with the partially estimated production of 1949. The average price of all fish to the fishermen decreased slightly from 1949 to 1950, although the values were generally variable and the prices of some species increased. San Pedro, Calif., continued to be the Nation's leading fishing port, both in quantity and value with landings of approximately 940 million pounds, valued at $43.5 million to the fishermen. Gloucester, Mass., was in secom place, with approximately 196 million pounds, followed by San Diego, Calif., with approximately 190 million pounds. The per- capita consumption of fishery products in the U. S. in 1950 totaled 11.5 pounds, edible weight. During the previous year the per-capita consump— tion was 11.4 pounds. This was considerably above the wartime level of approximately 9 pounds when a large portion of the canned pack was al- located to the Armed Forces and to lend-lease distribution. The 1935-39 average was 11.1 pounds. Fishery statistics of the U. S. and Alaska are compiled and published annually to make available information on both the economic and biological aspects of the domestic commer— cial fisheries. Phosphorus Exchange in Marine Phytoplankton, by Theodore R. Rice, Fishery Bulletin 80 (Fram Fishery Bulletin of the Fish and Wildlife Serv ice, Volume 54), 16 p., illus., printed, 15 cents, 1953. Phosphorus exchange in Nitzschia closterium, isolated and grown in pure culture, was demonstrated by using radioactive phosphorus and was shown to vary with changes in the phos— phorus concentration of the medium and with the physiological conditions of the cells. "A Report on the Fisheries of East Bengal, Pakistan," by A. R. K. Zobairi, article, pp. 116-20. (Fran The Progressive Fish Culturist, vol. 15, no. 3, July 1953, processed, annual subscription $1.25 domestic, US$1.65 foreign). Describes the fish— ery resources of the Province of East Bengal, the inland and marine fisheries, and how the Govern— ment aids the fishing industry. Spawning of Yellowfin Tuma in Hawaiian Waters, by Fred C. June, Fishery Bulletin 77 (From Fishery Bulletin of the Fish and Wildlife Service, Vol- ume 54), 21 p., illus., printed, 15 cents, 1953. This paper deals with the spawning of the yellow- fin tuna (Neothumnus macropterus) in Hawaiian wa— ters, with particular reference to the reproduc= tive process. Frequency distributions of the di- ameters of ova from 112 yellowfin tuna, captured by long-line gear in Hawaiian waters during 1950, demonstrate that several developmental groups of ova are’ present in the ovaries of this species during the breeding season. Based on the position of the mode of the most mature group of ova pres— ent in the ovaries, 11 arbitrary stages of matu- rity are defined which trace the development of the ova from the immature or resting stage through the spawning stage. A simple ovary-weight to fish-weight relation is given whereby spawning and nonspawning fish may be distinguished without laborious ova—diameter measurements. Over the size range of fish examined, 36.3 to 94.3 kilo— grams (80 to 208 pounds), the ovary-—weight to fish-weight relation was found to be linear for ovaries in the immature, or resting, stage and in one of the maturing stages. However, the slopes and levels of the two regressions were significantly different. The calculated number of ova produced at a single spawning by individ— ual yellowfin tuna, over the size range 47.2 to 88 kilograms (104 to 194 pounds), increased with fish size and ranged fram 2,370,000 to 8,590,000. Spawning of the yellowfin tuna in Hawaiian waters during 1950 took place between mid-May and the end of October, and coincided with the period of best long-line catches of the species.

"The Future of Echo Detection," by R. E. Craig, article, World Fishing, August 1953, vol. 2, no. 8, ppe 303-7, illus., printed, single copies 2s. éd. (35 U. S. cents), John Trundell (Publish— ers) Ltd., London, E. C. 4, England. Some of the possibilities in the development of echo— sounding apparatus are surveyed in this article. The effectiveness of frequencies rather higher than those used in the British commercial fish- eries, means of increasing the signal to noise ratio, method of presentation of paper recording, and methods of mounting oscillators horizontally for fish finding are discussed. The Gulf of Mexico Sponge Investigation, by Charles E. Dawson, Jr., and F. G, Walton Smith, Techni- cal Series No. 1, 28 p., illus., printed. Marine Laboratory, University of Miami, Coral Gables 34, Florida, 1953. Report on a survey of the Florida cammercial sponge beds from Dry Tortugas to Pana- ma City during 1947 and°-1948. Studies were made of the oceanographic conditions and fauna at 38 stations. No commercial sponges were found in CORRESPONDENCE REGARDING PUBLICATIONS THAT FOLLOW SHOULD BE ADDRESSED TO THE RESPECTIVE AGENCIES OR PUBLISHERS MENTIONED. IF READILY AVAILABLE, ARE SHOWN, DATA depths over 10 fathoms. Commercial sponges were found at 12 stations in depths between 3 and 10 fathoms. Abnormal biological conditions were ob- served at only one station. Although evidences of recent damage to individual commercial sponges were noted at several locations, no recurrence of the 1939 sponge disease was indicated. Oceanogra— phic conditions were generally within the range common to inshore Gulf of Mexico waters, and at no station did they deviate sufficiently to be con- sidered detrimental to the bottam-living organisms. Few sponges of commercial size were found at any locality, and the scarcity of small cammercial sponges precludes the early recovery of the Flor— ida sponze industry. The authors point out that since 1948 the mmber of diving boats working the Florida sponge beds has steadily declined. A re- cent inquiry at Tarpon Springs showed that there are now fewer than 20 diving boats operating full time in the Florida sponge fishery. This situa— tion will prove beneficial and hasten the recovery of the beds, state the authors, The reduction in fishing intensity will permit the remaining sponges to reach maximum size. In conjunction with this effect, a widespread seeding of the depleted grounds with small sponges is to be expected. Assuming that there is no further mass mortality, this new growth of sponge should be available for commercial exploitation in fram 7 to 8 years. The authors re— commend that the State of Florida enact legisla— tion and establish sour procedures for the strict enforcement of the five-inch minimum size limit. ‘Missouri Shell Game," by Jim Keefe, article, Missouri mA Conservationist, August 1953, vol. 14, no. 8, pp. 4-5, 12, illus., printed.

Onthe Skeena River, British Columbia, Canada, it has been estimated that a seal population of 450 de- troyed approximately 10 pounds of fish each daily—- a serious threat to the salmon fishery there— while salmon fishermen at Whitby, England, have been given permission to destroy seals which, it is claimed, are wreaking havoc with their livelihood. This article deals with the rela- tion between seals and the commercial fisheries in various parts of the world, and describes the four British seals. Refrigeration in America by Oscar Edward Anderson, Jre, 355 pe, printed, illus., $6.00. Princeton University Press, Princeton, N. J., for Univer— sity of Cincinnati, 1953. The subtitle "A His— tory of a New Technology and Its Impact" is an accurate summary of the book, There is compiled an exhaustively detailed and referenced account of refrigeration both from ice and mechanical equipment. Beginning with the harvest and use of natural ice, the author traces its applica— tion to food preservation in the United States. Mechanical refrigeration is likewise followed through the early developmental period and into the subsequent applications. Some of the other fields covered in the book include the ice in- dustry and domestic refrigeration, refrigerated transport, the cold-storage plant's struggle to attain recognition, impact of refrigeration on food supplies and habits, hame and locker-plant applications, and miscellaneous other industrial applications. The bibliographical note is an excellent resume of recommended sources for in- formation on the many fielids of research and development that have contributed to the advence of refrigeration to its present importance in the United States. The extensive footnotes are very worthwhile to further highlight the points made in the text. —Charles Bulter "Status of the Fishery for Sea Mullet (Mugil cepha- lus Linnaeus) in Eastern Australia," by J. M. Thomson, article, Australian Journal of Marine and Freshwater Research, May 1953, vol. 4, no. 1, pp. 41-81, illus., printed, 7s. 6d. per issue (US$1.05). Commonwealth Scientific and Indus— trial Research Organization, 314 Albert Street, East Melbourne, C. 2, Victoria, Australia. Var-— ious shortcomings of the statistical systems in vogue in the fisheries of the eastern States of Australia are discussed from the viewpoint of a biologist. It is impossible to campute an esti- mate of the catch per-unit-of-effort involving a time factor. The annual mullet catch for the whole eastern seaboard has remained substantial— ly about 14,000,000 pounds for the past lO years, but the total caught in any subdivision of the area has fluctuated widely. The Clarence River, Fort Macquarie, Maryborough, and Wallis Lake areas are the most important producers. There is ahigh degree ofcorrelation between the fluc- tuations in the mullet cetch and those in the total catch of estuarine fish. Thesize and age composition of the mlletcatch have shown only slight variation over the last 10 years, and there is no significant variation in this re- spect from the composition in 1903. The fluc- tuations in catch and catch per man are not incon— sistent with theories of overfishing nor with those of natural populetion cycles; but the only theory which receives confirmation independently of the curves of catch and of catch per man is an econom— ic one. Competition from both the trawling indus— try and the import industry has been responsible for the characteristics of the estuarine catch curves. It is estimated that the weight of meat to be gained from recent changes in the management of the fishery could at best be considerabley less than the amount of anmal variation in the catch.

The market-— ing problem and the program for constructing re— duction factories are also discussed. "Use of Chilled Sea Water in Place of Ice in Trans— porting Fish," by A. W. Lantz, article, Progress July 1953, pp» 39-44, illus., processed. Fisheries Research board of Canada, Pacific Fisheries Exper— imental Station, Vancouver 2, B. C. Describes a study which involves the mechanical chilling of sea water in a fish storage tank and maintaining the. water at 29°F.to 30°F. for transporting fish aboard a fishing vessel. An illustration shows one proposed application of this system for the hold of a troller vessel, using eutectic plates spaced to provide chilled sea water in each of six compartments. These compartments or sections re— place the fish pens in conventional fish-hold con— struction. An outstanding feature of the system is that it can be installed in wooden fishing craft without insulating the hull. It also eliminates the carrying and handling of ice, thus reducing operating and labor costs, Another illustration shows a further modification of this system in which the supporting walls or lateral bulkheads replace the eutectic plates; a bank of refrigerat— ing coils is placed at one end and circulation of the sea water is obtained by a pumping system. The equipment can be adapted to any type of boat. October 1953 COMMERCIAL FISHERIES 75 CONTENTS, CONTINUED PAGE PAGE TRENDS AND DEVELOPMENTS (CONTD.): FOREIGN poeta U. S.
