COMMERCIAL FISHERIES REVIEW June 1958 Washington 25,D.C. Vol. 20, No.6 DAMARISCOTTA (MAINE) ALEWIFE FISHERY By James P. Cating * Migrations of alewives (Pomolobus pseudoharengus) from the sea to spawning grounds in fresh water occur each spring along the Atlantic coast of North America from the Carolinas to Nova Scotia. In colonial times the sluggish rivers or streams, draining lake or pond systems, supported jarge alewife runs. In recent years Ris Nos FIG. 1 - STREAM APPROACH TO TRAP, SLUICEWAY, FIG. 2 - DIVISION POINT, RIGHT TO LAKE, LEFT TO AND PROCESSING PLANT. TRAP. the construction of tidewater dams preventing upstream movement of alewives, pol- lution and exploitation have greatly reduced and in instances eliminated alewife runs. The alewife spends most of its life in the ocean where it may reach a foot in length and attain a weight of one-half pound. In the spring mature fish enter the streams and move up into the ponds and lakes where they spawn. Most adult ale- wives do not die after spawning, as do the Pacific salmon, but survive to return to the sea. The young of the year begin their seaward migration and downstream movement during summer and fall months. The alewives remain in the ocean until they mature at an age of 3 or 4 years. The sight of these hordes of fish, working their way up small streams to the lake, is one that never fails to fascinate. The instinct to propagate the race is so % FISHERY METHODS AND EQUIPMENT SPECIALIST, MAINE HERRING EXPLORATION AND GEAR RESEARCH, BRANCH OF EXPLORATORY FISHING AND GEAR RESEARCH, DIVISION OF [INDUSTRIAL RESEARCH AND SERVICES, BUREAU OF COMMERCIAL FISHERIES, BOOTHBAY HARBOR, ME. 2 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 strong in these fish that they never cease trying to get upstream no matter what ob- struction is placed in their path. At the entrance to West Harbor pond at Boothbay Harbor, Maine, they can be observed at times oe to Benge a net that some- FIG. 3 - LOWER SECTION OF FISHWAY. FIG. 4 - FISHWAY POOL times cuts off the fishway entrance to the pond. They are so oblivious to everything but reaching the spawning ground that they can be easily caught by hand. Alewives are important to man in several ways: (1) as a source of food and (2) as a fine supely of deraee fish for the game fish in the waters where they are spawned and spend most of the sum- mer. Sometimes new runs are started in suitable lakes with outlets to the sea just to provide an adequate sum- mer supply of food for the trout, salm- on, or bass residing there. Alewives are good food fish either fresh or processed. Most of them, commercially processed for food, are either cold-smoked or pickled. Many people prefer them to sea herring processed in the same manner. Many of the alewives caught in Maine go into cat food and more and more are being processed for meal and oil. Some are utilized for lobster bait. One of the larger runs of these fish occurs in the Damariscotta River and lake system near Damariscotta, Maine. The location of the fishing op- eration is handy to U. S. Route 1. Each spring the migrating alewives are an attraction to many local and out-of-state people. The fishery is owned by the Town of Damariscotta, but the production is leased each year to a private party. The town is paid a percentage for the fish utilized. Visitors are definitely welcome. FIG. 5 - TRAP, SLUICEWAY, AND PLANT. June 1958 COMMERCIAL FISHERIES REVIEW 3 The methods by which these fish are taken and handled at Damariscotta are de- picted in Figures 1 to 10. It is probably one of the simplest and easiest methods of catching fish that has ever been developed, and it is possible only because of the single-minded purpose of the alewife to go upstream to the lake. Figure 1 is a downstream view from the fishway and fish trap, showing the stream ap- proach up which the fish come. The wooden strueture at the left of the pic- ture is the sluiceway down which the captured fish are washed to the scaling machine and processing plant shown in the background. In the plant the fishare mechanically headed, gutted, and filleted. Then they pass through a series of salt brines until properly preserved. Fi- nally they are packed in barrels ina mild vinegar pickle for shipment to other locations for final processing in- to a retail pack of pickled herring. A few of the fish are smoked whole in a small smokehouse nearby and some are sold as lobster bait. FIG. 6 - TAKING BLOOD SAMPLES. Figure 2 is a view of the division point where the fish can, by choice, turn right and ascend the fishway to Damariscotta Lake or turn left and be caught.

FIG. 8 - ALEWIVES ON RAMP. flow from the trap is greater than that from the fishway which no doubt attracts a higher percentage of fish to the trap than to the fishway. Figure 3 is a view looking upstream in the fishway from the division point. Figure 4 depicts a resting pool in the fishway part way to the lake. There are a number of these pools above and below this one through which the fish must pass. 4 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Figure 5 shows the fishing area from which the alewives are carried via an el- evated wooden chute or sluice to the processing plant. At the lower left fish netted with dip nets can be seen lying on the wooden ramp beyond the wooden trap chamber where the fish congregate. More ofthese wood trap FIG. 9 - IMPASSABLE FALLS ABOVE TRAP.

The fish come up the stream beside the man farthest right and when they are turned back by the falls they concentrate in the chambers where they are easily caught. Figure 6 - A blood sample is being collected from an alewife for later analysis. Through classification based on blood types and other characteristics scientists may be able to separate the alewife population into different racial groups. These biological studies being conducted by the Division of Biological Research of the Bureau of Commercial Fisheries are aimed at improving the alewife fishery. Figure 7 shows workman dipping fish from the channel on the left onto the ramp leading to the conveyor which carries the fish into the sluiceway. Figure 8 shows alewives, just dipped, flopping on the ramp. A pile of alewives can be seen in the background ready to be shoveled onto the conveyor. Figure 9 - In the background the impassable falls above the trap area can be seen. The water operating the sluiceway is taken from the falls. A wooden trap- ping chamber is in the foreground. Figure 10 - This is a cylindrical perforated mechanical scaler at the end of the sluiceway. From here the fish are taken into the plant for processing. The alewife is a very hardy fish and stands handling and transporting alive from one area to another well. It is estimated that only 5 percent are allowed to escape to spawn in some of the more heavily-fished streams along the coast of Maine, and these runs have not diminished significantly. Rounsefell & Stringer (1943) point out... "artificial maintenance, for more than a century, of a commercial run in Jones Stream (West Goldsboro) by planting about ten percent of each year's run in Jones Pond for spawning.'' There are many streams along the coast in the range of this fish in which runs could be established again providing pollution were abated June 1958 COMMERCIAL FISHERIES REVIEW 5 and fishways over impassable dams and falls were built. The alewife unlike the shad, can pass quite steep fishways. Establishment of new runs and better manage- ment of already established runs could increase the production tremendously. Rounsefell & Stringer (1943) state ''Production from alewife runs in Maine can be easily doubled by carrying out the suggestions embodied in this report in regard to fishways, natural obstructions, management methods to guarantee an adequate an- nual spawning stock, and by continuation of the stocking program." Increased interest by Maine towns, stimulated by the reports of Rounsefell & Stringer (1943) and Baird (1953-1956) in increasing the production of alewives by better management of present runs and the establishment of new ones by stream improvement and stocking gives promise of steady progress towards a practical maximum yield from waters suitable for Maine alewife production in the future. The biologists of the State of Maine Sea and Shore Fisheries and Inland Fish and Game Departments are encouraging this progress and assisting the towns by doing the needed research for establishing suitable management plans. It might be said that there is no market for alewives at this time and, therefore, it is not desirable to increase the catch. This would be partly true if they are con- sidered for kuman consumption only. Baird (1956) interviewed present alewife pro- ducers and was told that they could handle any steady increase in production with ease. He states... ‘our problem is not one of markets, but one of sufficient pro- duction to satisfy these markets.'' At the present rate of population increases in this country and most other countries any direct source of protein will by all pres- ent indications be of maximum importance in 10 to 15 years if not sooner. In the meantime the surpluses can be utilized by the producers of fish meal and oil and cat food who are definitely interested in any source of fish at competitive prices.

Van Engel* ABSTRACT BLUE CRABS ARE ABUNDANT ON THE EAST AND GULF COASTS OF NORTH AMERICA, ON THE EAST COAST OF SOUTH AMERICA, AND HAVE BEEN REPORTED FROM FRANCE, HOL- LAND, AND DENMARK, AND THE EAST COAST OF THE MEDITERRANEAN. IN CHESAPEAKE BAY, FISHING HAS BEEN INTENSIVE FOR OVER 80 YEARS; IN THE LAST TEN YEARS, THE AVERAGE ANNUAL PRODUCTION HAS BEEN ABOUT 60 MILLION POUNDS, VALUED ABOUT THREE MILLION DOLLARS, APPROXIMATELY TWO-THIRDS OF THE ENTIRE UNITED STATES BLUE CRAB HARVEST. MATING OF BLUE CRABS BEGINS IN EARLY MAY AND CONTINUES INTO OCTOBER; SPERM LIVE IN THE FEMALE RECEPTACLES FOR AT LEAST A YEAR, AND MAY BE USED AS OFTEN AS THE FEMALE SPAWNS, TWICE OR MORE, AFTER MATING, FEMALES MIGRATE TO THE SALTIER WATERS OF THE SOUTHERN END OF THE BAY, SOME PASSING INTO THE OCEAN. SPAWNING IS DELAYED AT LEAST TWO MONTHS AFTER MATING, AND OCCURS FROM EARLY MAY THROUGH SEPTEMBER. EGGS ARE CARRIED ON THE ABDOMEN OF THE FE- MALE FOR ABOUT TWO WEEKS BEFORE HATCHING. THERE ARE TWO LARVAL STAGES--FOUR OR FIVE ZOEAL MO},TS AND THE, MEGALOPS-- LASTING ABOUT A MONTH. LARGE NUMBERS OF CRABS REACH THE FIRST CRAB STAGE EARLY IN AUGUST AND BEGIN MIGRATING INTO THE RIVERS AND TO THE UPPER BAY. ADULT SIZE MAY BE REACHED IN ONE YEAR TO A YEAR AND A HALF, SHEDDING 18 OR MORE TIMES AFTER THE LAST LARVAL STAGE. TWO MAJOR MIGRATIONS OF ADULT FEMALES TO THE SOUTHERN END OF THE BAY OCCUR, IN OCTOBER AND NOVEMBER AND THE FOLLOWING MAY. NONE OF JHESE FEMALES SPAWNED BEFORE THEIR MIGRATION. SCHOOLS OF SEA-RUN OR OCEAN CRABS, THAT HAVE SPAWNED BEFORE, MIGRATE FROM THE OCEAN OR THE VIRGINIA CAPES AREA INTO THE BAY IN MID-SUMMER. ADULT MALES REMAIN IN THE BRACKISH RIVER WATERS THE YEAR ROUND, THE DIET OF BLUE CRABS INCLUDES FRESH AND DECAYING FISH OR MEAT, AND VEGETATION, YOUNG SETS OF CLAMS AND OYSTERS MAY OCCASIONALLY BE DESTROYED, BUT ON GROUNDS IN OPEN WATERS THE BLUE CRAB |S NOT GENERALLY CONSIDERED A SERIOUS PEST. BACKGROUND The blue crab, Callinectes sapidus Rathbun, belongs to the class Crustacea, which includes many familiar marine and fresh-water forms, suchas lobsters, cray- fish, shrimp, and barnacles. This crabis acommon inhabitant of muddy and sandy shores of the East Coast and Gulf Coast of North America, from Massachu- setts to Texas, and afew have been reported as far north as Nova Scotia and as far south as Uruguay on the east coast of South America (Rathbun 1930). Occasional speci- mens have been reported in Euro- pean waters, from France, Hol- land, and Denmark, and it has be- come abundant in recent years on the Mediterranean coast of Israel, where the crabs were probably transported in the ballast tanks of Q ig iS tJ } a SS ic} Q S 3 a & = = = e B=} < io} 2 re ‘0 1880 1890 1900 1910 1920 1930 1940 1950 ships (Holthius and Gottlieb 1955).

ASSOCIATE BIOLOGIST, VIRGINIA FISHERIES LABORATORY, GLOUCESTER POINT, VA. June 1958 COMMERCIAL FISHERIES REVIEW 7 Bay. It is caught by many and diverse forms of fishing gear in salty, deepchannels. of the Bay and in brackish waters of its river tributaries, often quite far up the rivers in water of extremely low salinity. Total catch in Chesapeake Bay has fluctuated considerably in its 80-year his- tory (fig. 1), although in the early years, from 1880 to 1915, fluctuations were un- noticed. Since 1929, the average annual catch has been about 55 million pounds. In the last ten years, Chesapeake Bay has had an average annual production of about 60 million pounds, currently valued at about $3 million, approximately two-thirds of the entire United States blue crab harvest. Many closely-related crabs have the same characteristic body form, the flatly- expanded final segment of the fifth leg, and nine pairs of spines lateral to the eyes. The best diagnostic character of Callinectes sapidus is a set of four, instead of six, teeth on the margin of the shell between the eyes (two frontal and two inner-ocular teeth)--Rathbun 1930. Detail which will not be repeated here may be found in the authoritative accounts on taxonomy and distribution (Rathbun 1896, 1930); anatomy and histology (Cochran 1935; Cronin 1942, 1947; Hopkins 1943, 1944; Pyle and Cronin 1950); bibliography (Cronin, Van Engel, Cargo and Wojcik 1957). MATING Sex of the blue crab is easily recognized by differences in shape of the abdomen, or apron as it is frequently called (fig. 2), and by the abdominal appendages. The male abdomen, long, slender and ' T-shaped, carries two pairs of ap- pendages used in mating, two long intromittent organs and two short- er accessory organs. The abdo- men of an immature male is tight- ly sealed to the ventral surface of the shell, while on a mating male the abdomenhangs free or is held in place by a pair of ''snap-fasten- er-like''tubercles. In the young female the abdomen is triangular and sealed to the body, while in the adult it is broadly rounded, FIG. 2 - ABDOMENS OF IMMATURE FEMALE (A), MATURE FE- almost semi-circular, and free MALE (B), AND MALE BLUE CRAB (Cc). ; of the ventral shell. There are four pairs of swimmerets on the female abdomen: small, hairless rods on the im- mature and large, fringed rods on the adult. Abdomens of young females are gray- ish-white, adult females blue-green. In the last few days of immaturity, however, just before the young female sheds to become an adult, the dark green of the inner, soft, adult abdomen shows through the transparent whiteness of the hard, outer, immature skeleton. Young females sometimes are called "Sally'' crabs, while an adult female is a "sook,'' a twist of the word "'sow.'' Although millions of crabs were handled yearly in the last 75 years, only a few ''adult'' females were found with an inner, new skin showing beneath the outer skeleton, and where legs were missing, the buds of new legs often were found. All such crabs were abnormal and died before shedding was complete (Hay 1905; Churchill 1919; Cronin, personal communication). This is taken as proof that once the sook stage is reached, females cease to grow and molt. i ! Males, called "Jimmies," 'Jimmy-dicks," or 'Channelers,'' reach sexual ma- turity before they are fully grown, and during each of their last three growth stages may mate with more than one female (Truitt 1939). The female mates usually while it is in the soft crab state (Rathbun 1896), but not until after it has shed for the last 8 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 time. Mating two or three days after shedding, sometimes with two or more males in succession, occurs in experimental ponds, but in nature mating probably is sel- dom delayed this long. Summer is the mating season in Chesapeake Bay, beginning in early May and continuing into October, reaching a peak in late August and early September. Having found a mate, the male cradle-carries the female beneath him by hook- ing his first walking legs and pinching claws between the first walking legs and pinching claws of the female (fig. 3). She is carried two or more days until she sheds her immature shell. While she is shedding, the male hovers over her. After the soft female emerges from the shed she turns over on her back and unfolds the abdomen to expose the two genital pores. Mating may occur day or night and may last from five to twelve hours. Sperm are transported in microscopic, oval-shaped bundles called spermatophores to a pair of sacs in the female called Seminal recep- tacles or spermathecae. Sperm will live in the female receptacles for at least a year, to be used as often as the female lays eggs. After mating, the adult female is again carried, cradle-fashion, beneath the male, for another two days or more. While the male is carrying and mating with the female, the pair is called "doubler" or "buck-and-rider." Since the female mates only once, in the soft-shell state or shortly thereafter, the cradle-carry is undoubtedly important to ensure that a male is present at the critical moment of shedding, and to protect the soft fe- male until her shell is hard. Soon after mating, fe- males migrate to the salt- ier waters of the southern end of Chesapeake Bay, some passing through the Capes into the ocean. This migration results in a con- centration of adult females in the lower Bay; near the mouth of the Bay the catch is almost 100 percent fe- male (Fiedler 1930; Truitt 1934). SPAWNING : : Two tonine months may FIG. 3 - DOUBLERS. THE MALE CRADLE-CARRIES THE IMMATURE FEMALE @lapse between mating and FOR TWO OR MORE DAYS UNTIL SHE SHEDS. egg laying by the female (Churchill 1919). If mating occurs as early as May, the first egg mass may be laid in August. Although most females mature and mate in August and September, and eggs in the ovaries of each female develop almost to completion within the next two months, egg-laying is de- layed until the following May or June. In early spring females in the southern end of the lower Bay move first shoreward to warmer banks and near river mouths, but by June begin to retreat from excessive shoal water temperatures to spawn offshore. Far upstream in low salinity waters of Virginia rivers and in Chesapeake Bay north of the mouth of the Rappahannock River, sponges (masses of eggs released by fe- male crabs) seldom are seen except in unusually dry seasons (Truitt 1939). Egg laying is rapid and may be complete in two hours (Truitt 1939), eggs passing from the ovaries to the outside by way of the seminal receptacles where fertilization oc - curs. Outside the body, the fertilized eggs are attached by adhesives to hairs of June 1958 COMMERCIAL FISHERIES REVIEW 9 four pairs of appendages (swimmerets) on the abdomen. Appropriate names for egg-bearing females are sponge crab, cushion crab, lemon or orange crab, berry or berried crab, ballie, punk, and busted sook. In the sameway that poultry pullets produce infertile eggs, unmated crabs may produce sponges of unfertilized eggs, but this is extremely infrequent for there is always an abundance of males, each capable of mating with several females. When first laid eggs are bright orange in color, but during the two weeks be- fore hatching they become yellow, brown, and then dark brown. These color changes are caused by a gradual absorption of yellow egg yolk by the crab embryo and de- velopment of dark pigment in the eyes. The dominant color of sponges changes from bright orange near river mouths to dark brown at the Virginia Capes. A few sponge crabs may be seen before the end of April, but normally the first peak of sponge production occurs during the last week of May and the first two weeks in June. A second, smaller peak occurs in August, after which there is a rapid decrease in number of spawning females, and usually none can be found by the middle of September. On rare occasions a sponge crab has been caught as late as mid-December. Accompanying the rapid decrease in number of sponge crabs in September is an almost complete disappearance of females which had spawned. It is believed that most of them move to deeper waters of the Bay, or to the ocean, and die, or perhaps join an ocean-going population that may return to the Bay as "sea-run" or "ocean" crabs the following year. The few spent females that re- main in the lower Bay over winter comprise five percent or less of the dredge catch. They are markedly different in appearance, with dark-colored shells, quite unlike the bright colored shells of newly-mated, down-river migrants, but devoid of the fouling organisms so characteristic of ''ocean'' crabs (Newcombe 1945; Hop- kins 1947). Some females may spawn twice or more. Those that mate in August usually produce their first sponge the following May or June and a second sponge the suc- ceeding August, using only a portion of the sperm in the receptacles at each spawn- ing. Empty egg cases on the swimmerets are conclusive evidence that a crab has spawned, but do not reveal whether the sponge was the first, second, or a later one to be released (Churchill 1919). Absence of egg remnants, on the other hand, is not proof that the crab has not spawned. Although remnants are most numerous immediately after the hatch, most are soon lost except for an occasional case at the bases of swimmeret hairs. However, proof can be obtained from a parasitic worm, the nemertean Carcinonemertes, whose spawning is intimately dependent on the crab laying eggs. The presence of only small worms on crab gills is evidence that the crab had not spawned; adult-sized worms are evidence of spawning. (Humes 1942; Hopkins 1947). EGGS AND YOUNG The number of eggs in a sponge ranges from 700,000 to over 2,000,000 (Church- ill 1919; Robertson 1938; Truitt 1939). Many of the eggs do not hatch, and still fewer larvae and very small crabs live to become adults. On the average only one ten-thousandth of one percent (0.000001) of the eggs survive to become mature crabs. Eggs may be killed by a fungus, may be eaten by small worms, suffocate in stagnant or slow-moving water, or die from temperatures too high or too low (Couch 1942; Humes 1942; Rogers-Talbert 1948). After hatching the young crab passes through two larval stages, zoea and meg- alops, before it takes the form of a crab. The zoea looks like a shrimp and bears a heavily-spiked hood, while the megalops looks like a miniature toad that still re- tains its tadpole tail (figs.4and5). The zoeal form lasts about a month, during which it molts at least four times, growing from ;4, to about Ba of an inch in width 10 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 (Churchill 1919, 1942; Hopkins 1943, 1944; Sandoz and Rogers 1944). It has been impossible to rear larvae in the laboratory past the third instar, but some zoea identical with the third, except for larger size and better developed appendages, These have been found among the have been tentatively identified as ''fourth zoea."' numerous, minute organisms found in surface water near the mouth of the Bay. It has been suggested that there may also bea fifth zoea'' (Hopkins 1944), and perhaps a sixth intermediate form, a meta- zoea, preceding the mega- lops stage (Snodgrass 1956). When the water has a very low salinity, larvae hatch prematurely and die in a prezoeal stage. Those that hatch normally at av- erage or high salinities may be eaten by jellyfishes, comb- jellies, fishes, and many other enemies. Survival should be best in the south- ern part of Chesapeake Bay because salinity, tempera- ture, and food conditions there compare well with optimum conditions deter- mined for hatching and growth in the laboratory (Sandoz and Rogers 1944). The greatest concentrations of zoeae are found in the channel region between Cape Charles and Cape Henry and diminishing numbers both up-Bay and seaward. Almost no zoeae have been found up-Bay above the Virginia-Maryland line (Truitt 1934, 1939; Churchill 1942; Graham and Beaven Sai a pe a Ge Po eencteAy Ag IBSl ZOEA, AND SECOND ZOEA OF THE BLUE CRAB. distribution of zoeae is con- sistent with experimental evidence that salinity has an influence on success of hatch- ing. An attraction to light may also have survival value. Concentration of zoeae in the upper levels in open waters is consistent with experimental evidence that zoeae reared in darkness do not molt (Sandoz and Rogers 1944). Following the fourth (or fifth) molt is the megalops stage. Many of the larvae that hatch in early June reach this stage by mid-July or the first of August. Little is known of the conditions that are most favorable for survival and de- velopment of megalops. A few have been caught in the southern part of the Bay and on the ocean coast, on the bottom in 20- to 40-foot depths, near the surface in open water, but none at intermediate levels (Truitt 1934; Robertson 1938; Goellner 1941; Churchill 1942). It is attracted to light, but settles to the bottom when swimming June 1958 COMMERCIAL FISHERIES REVIEW 11 ceases (Robertson 1938; Van Engel, personal observation). Occasionally in late Au- gust or early September large numbers of megalops appear along the ocean front at Virginia Beach, biting swimmers with their minute pinching claws and giving rise - to numerous complaints of "water fleas" (Truitt 1939). No explanation has been offered for these concentrations of meg- alops in breaking waves. The megalops stage lasts only a few days. When it molts the "first crab" appears, with the typical body shape of an adult crab. Migration of large numbers of adult females past the Capes to the ocean, and subsequent appearance of megalops along the ocean beaches, suggest that a sub- stantial amount of spawning may occur outside the Bay. As yet, no estimate of the importance of this ocean spawning in providing crabs to the Chesapeake Bay supply has been possible. Early in August, when many crabs reach the "first crab'' stage, one-tenth of an inch wide, they begin migrating from the southern part of the Bay and the ocean adjacent to the Capes into the rivers and to the upper Bay. The first wave of migration reaches the rivers on the western shore of Virginia about the third week of August, and crabs one-quarter to one-half inch in width are commonly seen during September and October. In most years small crabs do not migrate farther north than the mouth of the Potomac River before cold weather begins, and most of them remain in Virginia waters over winter. Movement up-Bay is resumed the following spring. Crabs one-half to one inch in width usually are first seen in the upper Bay in late April or May the year following the hatch (Hay 1905; Truitt 1934, 1939). FIG. 5 - MEGALOPS OF THE BLUE CRAB. GROWTH Growth is rapid and adult size may be reached one year to a year and a half after hatching (fig. 6). Those hatched early, in late May, become two and one-half inches wide by November and five-inch adults or larger by August the following year. Those that hatch in late August or September may reach only one-half inch in width the first fall. By November the next year these will have become only three or four inches wide and will not become adult until May of the third summer. After reaching adult size, crabs are known to live at least one more year, and a few may reach the maximum age of three to three and one-half years. The average life-span, however, probably is less than one year (Hay 1905; Churchill 1919; Truitt 1939; Van Engel and Wojcik unpublished data). Because the crab is covered by a hard, inflexible shell, an increase in size oc- curs only when it sheds. Small crabs shed frequently, but the time between molts increases as crabs grow larger. The smallest crabs, about one-fifth inch wide, shed every 3 to 5 days, those one-half to one inch wide every 10 to 15 days. Atfour inches and larger shedding occurs at intervals of 20 to 50 days (Churchill 1919; Robertson 1938; Van Engel, Wojcik and Sandoz, unpublished data). Shedding does not usually occur in Chesapeake Bay from November through the first week in April, although on rare occasions a soft crab has been caught in deep water in December. 12 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 In preparation for shedding, a new shell is formed beneath the hard, outer shell, becoming darker in color as it develops and visible through several parts of the out- er shell, especially in the last two sections of the fifth pair of legs, the swimming ADULY FEMALE 6 INCHES 18 MONTHS MINIMUM LEGAL S|ZE 3 }NCHES 72 MONTHS paddles. Around the outer edges of those sections are many fine hairs, called setae, at the base of which there is a thin, dark brown line which represents the outer edge of the hard shell. It is just inside this brown line that the color of the new shell can be observed. June 1958 COMMERCIAL FISHERIES REVIEW 13 ' which requires the The earliest recognized color stage is the ''white-rim,' longest time to shed, from one to two weeks. The following stage, "bink-rim,'' may be expected to shed in 3 to 6 days, while the ''red-sign" peeler will shed in 1 to 3 days. ''Peeler" is the name given by most watermen to the red-sign crab, although the term is sometimes loosely applied to all crabs showing color signs of approach- ing shedding. To free the developing new skeleton from the old, some carbohydrates and pro- teins and about five percent of the calcium are resorbed from the base of the old shell. These are stored inthe softtissues of the crab, principally in the hepatopan- creas, and may be used for building and later hardening the new shell (Hecht 1914; Scheer 1948, 1957). Muscle attachments on the old shell are loosened and shifted to new origins on the future exoskeleton. Feeding ceases, sometimes a day or two before shedding, probably as a result of weakened muscles and inability to grind food, and in preparation for the eventual loss of the stomach lining at shedding. When shedding starts, the outer shell cracks along definite lines so that the upper and lower halves of the shell may gape. The cracked-shell stage is called a ''buster.'’ Once this stage is reached, the crab slowly backs out of the partially- opened shell; shedding of 4- to 5-inch crabs is completed within 2 or 3 hours. When completely free from the old shell, the crab is called a "soft crab.'' During the few minutes preceding and immediately following shedding large amounts of water are taken in by the crab. Absorption of water occurs through permeable membranes, in many crustaceans the gills, and in some the stomach (Robertson 1957). Expan- sion to full size, when all wrinkles in the new skin are smoothed, is completed a- bout two hours after shedding and the soft, pliable covering then begins to harden. Over the next 9 to 12 hours the shell has a papery or leathery texture and the crab then is called a “paper shell.'' During the next 12 to 24 hours the shell becomes stiff and brittle, and the crab is referred to as a "'buckram.'’' More and more fre- quently, ''paper shell" and ''buckram" are being used as synonyms for the stage be- tween soft and hard crab, with less attention being given to whether the shell is leathery or stiff and brittle. Another three days will pass before the shell is rigid. Since the interval of time between molts is less for small thanforlargecrabs, time intervals between various peeler and hardening stages are much shorter than those given above. In the post-molt period, the shell thickens and hardens with the addi- tion of new layers and deposition of calcium and some organic substances. About 95 percent of the minerals are absorbed directly from the water or derived from food (Hecht 1914; Scheer 1948; 1957). At each normal shedding, there is an increase in width one-quarter to one-third the initial size (Churchill 1919; Gray and Newcombe 1939; Van Engel, Wojcik, and Sandoz, unpublished data). Amount of increase may be genetically controlled in part, but it is believed that environmental conditions have an equal if not greater influence. Unfavorable water conditions, inadequate food, and injuries, such as the loss of one or more legs, result in smaller percentage increases, as low as 5 to 10 percent and possibly even no increase in size. In normal soft crabs, an increase in size is due to swelling of the body by absorption of water. Since the amount of water absorbed is related to the salt content of the surrounding water, greater in- creases in size should occur in water of low salt content (Baumberger and Olm- stead 1928: Scheer 1948; Knowles and Carlisle 1956). That this is probable is dem- onstrated by the large size of crabs in tributaries of low salt content and the small size of crabs along the salty ocean coast of the Eastern Shore (Newcombe 1945; Henry 1951; Porter 1955). It has been shown that the eyestalks of certain crabs produce a water-regulating hormone (Knowles and Carlisle 1956). It is possible that the number of molts is fixed and that a crab stops growing after shedding a certain number of times. Thus, the great difference in size of crabs of the same age, or of adult crabs, may be simply the result of different percentage increases in size at each molt. 14 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Recent studies on other crustaceans show that the eyestalks and the second max- illae produce hormones which either prevent or encourage molting (Kleinholz 1957). The quantities of these chemical substances are partly controlled by temperature, light, and by other hormones (Knowles and Carlisle 1956). The failure of blue crab larvae to molt when reared in darkness (Sandoz and Rogers 1944) may be an exam- ple of hormonal regulation. Molting may also be controlled by hormonal secretions from the ovary, which develops rapidly following the last molt, or from the eggs after they are laid (Donahue 1955). Definitions of Blue Crab Terms Abdomen or apron--the "'tail'' of a crab. Ballie--sponge crab, a female with an egg mass be— neath the abdomen. Berried crab or crab in berry--sponge crab. Buck and rider--pair of mating crabs; a doubler. Buckram crab--having a pliable, leathery shell, fol- lowing the soft crab condition. Buffalo crab--soft crab with large claws missing, often lost in shedding. Busted sook--sponge crab. Buster--shedding crab which is beginning to emerge from its shell, Channeler or chandler--large male that remains in the deeper channels of a river during the summer; jimmy crab. Cushion crab--sponge crab, Doubler--pair of mating crabs; buck and rider. Fat crab, green crab, or snot crab--these terms are used by mést watermen in referring to a crab ap- proaching the shedding period and showing a white- rim color sign just within the margins of the two outer segments of the swimming legs; the terms are more popularly used in referring to any hard crab with firm meat, somewhere between the buck- ram and peeler phases. Green crab--white-rim crab. Hard crab--crab having a hard shell; following the buckram condition. Jimmy crab, jimmy dick, or jimmy channeler--a very large male crab; channeler. Lemon crab--sponge crab. Life history stages--there are four main stages: the egg, zoea, megalops, and crab, The zoeal and mega- lopal stages combined are called larval stages, while the crab stage is a post-larval stage. Megalops--crab larva, between the zoeal and crab stages; about eth of an inch wide. Metazoea--larval stage thought to occur between the fifth zoea and megalops stages; should have well de- veloped thoracic appendages. Nicking a crab--to break the movable fingers of the claws to prevent the use of the claws as pincers. Orange c.ab--sponge crab. Paper-shell crab--having a hard shell which is easily cracked, following the buckram stage. Peeler crab--hard crab which has a fully formed soft shell beneath the hard outer shell; a red-sign crab. Sometimes applied to white-rim, pink-rim, and red- Sign crabs. Pink-rim--following the white-rim condition; there is a thin pink line along the inner border of the back fin; may be expected to shed within a week. Punk--sponge crab. Rank peeler--red-sign peeler just before the shell be- gins to crack; almost a buster. Red-sign peeler--following the pink-rim stage; there is a thin red line along the inner border of the backfin; may be expected to shed within two days. Sally crab--young female crab; an immature female. "Seconds''--crabs that have just turned from a white-rim to a pink-rim condition. Shed--meaning either the empty shell or the casting off of the shell. Snot crab--white-rim crab named because of the watery substance which issues from the break of the crab claws when they are nicked. Soft crab--crab which has just emerged from the old shell and has a new, soft, pliable shell. Sook--an adult female crab. Sponge crab, ballie, berried crab, crab in berry, busted sook, cushion crab, orange crab, punk, and lemoncrab-- names given to the female carrying anegg mass on the abdomen. Swimmerets--the finlike attachments to the underside of an adult female crab, on which the eggs are carrieduntil they hatch. White-rim crab--the fat, green, or snot crab condition; there is a thin white line along the inner border of the back fin; may be expected to shed within two weeks. "Ticky" crab--one that smells of iodoform, probably be- cause it had eaten a marine bottom animal called Bal- anoglossus. et Zoea--the larva that hatches from the crab egg: about ws th of an inch long. Females in the family of swimming crabs (Portunidae), of which the blue crab is a member, may be the only crustaceans known to complete their growth in size at the time they become sexually mature. Males in this family and both sexes of many other crustaceans continue to molt and grow after the gonads are fully de- veloped. The female blue crab becomes sexually mature and stops growing after 18 to 20 molts, not counting the 4 (or 5) molts in the larval stage (Van Engel, unpublish- ed data). As stated previously, this event is accompanied by a change in shape of the abdomen, from triangular to semicircular. Internally, however, few abrupt changes occur, since the growth of tissues is gradual throughout the life of the fe- male (Cronin, 1942): the seminal receptacles grow to full size-in the interval be- tween the last two molts; the ovary expands to full size after the last molt (Van En- gel, unpublished data). Sexual maturity in males is probably reached in about 18 or 19 molts following the last larval stage, but growth does not cease, for they may shed 30r 4 more times. One male reared from the megalops stage reached six and one-half inches in width after 23 post-larval molts, after almost 3 years of confinement in laboratory a- quaria (Van Engel, unpublished data). June 1958 COMMERCIAL FISHERIES REVIEW 15 MIGRATIONS Two major migrations of sooks have been observed along the western shore of Chesapeake Bay, the first in October and November, following the peak of the mat- ing season, and the second the following May. The fall migrations results in a concen- tration of sooks in the lower Bay in the deep channels which are the continuations of the river channels. Large schools occasionally have been seen passing through the Capes into the ocean, where they have been taken by crab dredges and fish trawlers close to shore in depths less than 40 feet, but rarely in deeper waters farther offshore (Truitt 1934). Schools of adult females migrating down river in Mayconsist in part of females recently mated, but mostly of those that mated late the previous fall and were forced by low temperatures to over-winter en route to the lower Bay. Large concentra- tions of these migrants are caught in May near the mouths of the rivers of the west- ern shore. Some schools are especially noticed because the crabs are unusually large, and because often many are heavily fouled with ribbed mussels (Hay 1905; Van Engel, unpublished data). Apart from the migration of sooks each fall and spring toward the southern end of the Bay prior to first spawning, schools of ''sea-run" or "ocean"' crabs ap- pear in late July or early August in the Lynnhaven Roads area. Familiar to com- mercial fishermen along the southern shore of the Bay, these schools of old-look- ing, moss-covered, barnacle-encrusted females crowd close to the beaches, where they remain from one to four weeks (Newcombe 1945). Large concentrations oc- casionally migrate into the James River, where, as in the summer of 1954, they may add substantially to the commercial catch. These crabs usually are sighted first in the ocean as they move north toward the Capes. The growth of fouling or- ganisms on their shells is in marked contrast to the brilliant blue and white colors of down-river migrants. On rare occasions, following strong northerly winds, the remains of many thousands of dead "'ocean"' crabs litter the beaches (Hay 1905; Truitt 1939; Newcombe 1945). Crab dredgers report that in winter in the vicinity of Cape Henry crabs are often of strong odor, have shells deeply pitted, and produce a very small quantity of very inferior meat, and catches of this kind are quickly dumped overboard. These crabs may be the remnants of "ocean" schools (Truitt 1939). Those with a strong odor are called "'ticky'' crabs, possibly because the odor is similar to iodoform which in turn is similar to the odor of bed bugs (bed ticks). When females migrate down-river to the lower Bay, adult males remain in brackish river waters and many move farther upstream, mating with other females. In the first 20 to 25 miles upstream from the mouth of the York River the sexes are about equal in numbers, but the percentage of males increases gradually with dis- tance upstream (Wojcik, unpublished data). This distribution is probably depend- ent on the salinity gradient and may vary seasonally and between rivers. FOOD The diet of blue crabs includes fresh and decaying fish or meat, as well as vegetation. Roots, shoots, and leaves of common seaweeds are regularly eaten, especially parts of eelgrass (Zostera), ditch grass (Ruppia), sea lettuce (Ulva), and salt-marsh grass (Spartina)--Truitt 1939. Destruction of young quahogs (Ven- us) and seed oysters (Crassostrea) in experimental ponds and tanks has been fre- quently reported (Lunz 1947; Loosanoff and Chestnut 1948; Carriker 1951; Carver 1957). On clam and oyster grounds in open waters, however, the blue crab cannot be considered a serious pest, although transplants of young sets may be destroyed 16 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 when other food is less available (Loosanoff and Chestnut 1948; Menzel and Hopkins 1956). Because its diet is varied, the blue crab is attracted to almost any bait; tough trash fish or slaughterhouse trimmings are preferred for trotlines, but oily fish are preferred for crab pots. The food requirements of larval crabs are not well known. Zoeae will eat many microscopic plants and animals but will not grow unless fed certain proto- zoans, the yellow dinoflagellates (Robertson 1938; Sandoz and Rogers 1944). The megalops is omnivorous, however, and may be fed bits of fresh fish or shellfish or green aquatic plants. LITERATURE CITED BAUMBERGER, J. PERCY, AND OLMSTEAD, J. M. D. 1928.

NEW BEDFORD SCALLOP FISHING FLEET There are about 70 or 80 boats of the New Bedford fishing fleet riggedfor sea scalloping. They range from 60 to 100 feetlong and are powered by Diesel engines up to 550 horsepower. All are equipped with depthfinders, Loran navigating sets, and ship-to-shore radiotelephones. Almost all of them are fairly new and extremely seaworthy craft. A winter gale on Georges Bank will soon seek out the weaknesses of any vessel. Construction and deck arrangement is very similar to the usual medium-size New England dragger. Many of the boats change overfrom trawling to scalloping and back again to accommodate themselves to changing fishing and market- ing conditions. Any well-found dragger can rig upfor sea scallop- ing by removing the nets and otter boards and taking aboard the shucking boxes, wash tank, and the booms necessary for handling the dredges. The same double-drum fishing winch, wire rope, and forward gallows frames are used. --Fishery Leaflet 442, Sea Scallop Boats and Gear (August 1957). 18 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 FROZEN PACKAGED HALIBUT VOLUNTARY STANDARDS DISCUSSED AT MEETING A public meeting to discuss the first proposed draft for voluntary standards for frozen packaged halibut was held on April 1, 1958, at the Bureau of Commercial Fisheries Technological Laboratory, Seattle, Wash. In attendance were 10 representatives of the fishery industry, a representative of the National Fisheries Institute, and technical personnel of the Seattle Technolog- ical Laboratory. All halibut producers, processors, and related members of indus- try were invited by an advance notice which appeared in the Bureau of Commercial Fisheries Market News Service ''Fishery Products Reports." Local industry displayed a positive, helpful, and interested approach toward the development of a realistic and meaningful standard by their numerous questions, dis- cussions, and critical evaluation of each of the various quality factors considered. The proposed standard for determination of grade is based on (1) the evaluation of quality factors rated by score points in the frozen, thawed, and cooked states and (2) the evaluation of the quality factors of flavor and odor in the cooked state, but not rated by score points; the dual results thus obtained fix the maximum grade limit that the product can achieve. Copies of the latest draft are available upon request from the Bureau of Com- mercial Fisheries Technological Laboratory, Seattle, Wash. Funds made available by Public Law 466 (83rd Congress), commonly referred to as the Saltonstall-Kennedy Act, have been used to expedite progress on the Bu- reau's program for the development of voluntary Federal standards. The National Fisheries Institute, acting as a contract research agency for the Bureau, has sup- plied the industry liaison essential to the standards program and has furnished con- sulting services at meetings and conferences on these standards. 2s © PROGRESS IN FISH-OIL RESEARCH In the past, the bulk of the fish oil produced by the United States fisheries went into the manufacture of paint and soap. With the development and use of synthetic substitutes for oil in these products, the major part of American-produced fish oil is exported to Europe, where it is made into margarine. Should unanticipated de- veloments upset or eliminate this market, new uses would have to be found for fish oils, or they would undergo a drastic reduction in price. The present research pro- gram of the U. S. Bureau of Commercial Fisheries is aimed at developing uses for fish oil that could replace the European margarine market, should this become nec- essary. June 1958 COMMERCIAL FISHERIES REVIEW 19 The characteristics and the potential uses of fish oils long have been subjects of great interest to research workers in the Bureau. The unique composition and structure of fish oils, consisting of long-chain fatty acids with many double bonds, present a challenge to the oil chemist and to the food technologist. Most uses for which fish oils are employed at present make no use of these properties. In many cases, the characteristics of fish oils even are considered a distinct disadvantage. Instead of trying to overcome the alleged disadvantages of fish oils in order to make them competitive with animal and vegetable oils, Bureau chemists decided to take advantage of these unique proper= ties and to investigate their potentialfor the manufacture of industrial and phar- maceutical products. Development of these products requires an extensive research program, Less is known about the chemical structure of fish oils thanis known about the structure of animal or vegetable oils. The reasons for this are (1) the complex nature and instability of fish oils and (2) lack of funds to pursue the investigation.. In 1955, with the availability of more adequate funds from the Salton- stall-Kennedy Act of 1954, the U. S. Bu- reau of Commercial Fisheries was able to expand this research. Since that time, 21 projects in 16 different labora- tories have been undertaken. Twelve of these projects essentially are basic in- vestigations of the structure and reac- tions of fish oils, whereas the other nine PEGISOES ERS CEsn yes! uO Ceveloo jgeae= RUNNING A SPECTROGRAM ON A FRACTION OF ALKALI - tical uses for fish oils and for the com~ “| somerizeD LONG-CHAIN FATTY ALCOHOLS FROM FISH pounds manufactured from them, OIL. The basic research projects are varied. They include analyses of (1) the com- position, structure, and chemical reactions of fish-oil fatty acids, (2) the composi- tion of the fish-oil components other than fatty acids, and (3) the physiological ef- fect on animals of ingesting fish oils or their components. The fundamental infor- mation developed from these investigations forms the foundation for an intelligent applied research program. The applied research projects also are varied. They include investigations of the value of fish oils or their derivatives (1) in poultry and swine feed, (2) as fungi- cides and insecticides in agriculture, (3) as a basic ingredient in the manufacture of resins, (4) as leather lubricants, and (5) as ore-flotation agents. Work also is being done on improving methods of processing fish oils. During the relatively short period since 1955 when the stepped-up research program on fish oils got under way, a number of papers have been written, In ad- dition to those that are in the process of being prepared, 32 papers either have been published, or are in press. 20 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 REPORT ON DEVELOPMENT OF FUNGICIDES FROM FISH OIL This investigation has been under the supervision of Dr. Boris Sokoloff, Direc- tor of the Southern Bio-Research Laboratory, assisted by I. Chamelin, Akira Kato, George Renninger, and Maxwell S. Simpson, The object of the investigation was to modify whole crude fish oil in relatively simple ways, without purification or separation of active ingredients, so as to in- crease the anti-fungal activity of the oil to an effective level. Simple laboratory screening tests for fungicidal activity were developed using cultures of various fungi isolated from citrus trees and fruit. At later stages, pure cultures of a selected group of fungi and bacteria of pathological significance were used for the screening tests to provide a wider spectrum for determining general antibiotic activity. In this manner more than 170 fish-oil preparations were tested, and the more active compounds were also used in limited tests on citrus seedlings to determine whether they caused detrimental effects on foliage. Ideally a compound costing less than 25 cents a pound was desired which was stable, water-soluble, nontoxic, and biologically active at 0.1 percent concentration. Various combinations were tried of saponification, chlorination, and sulfation of the crude fish oils, with addition of chemicals such as ammonia, formalin, several me- tallic hydrides, and metal ions to the process. As indicated, none of these preparations or mixtures was purified to the extent that identification of the individual chemical compounds was possible. Because of the complexity of the fatty-acid mixture in the crude fish oils, this step would have been too expensive and time consuming to consider with the funds granted for the investigation. The contractor was successful in materially increasing the fungicidal and fungistatic properties of fish oils as evidenced in laboratory screening tests. However, it was found in the course of testing on citrus seedlings that none of the compounds was satisfactory enough to justify pilot-plant scale preparations and more extensive field tests. Most of the active fish-oil compounds were not water soluble or proved to have toxic effects on the plants, and the emulsified preparations were unstable and had poor distribution and penetration due to their oily nature. The water-soluble compounds unfortunately were usually low in antifungal activity. One preparation--essentially a crude fish oil treated with ammonium hydroxide in acetone, saponified with sodium hydroxide, and then mixed with a small amount of potassium borohydride--was judged to be fairly satisfactory. The unknown chem- ical composition of this preparation and the probable difficulty in adapting the lab- oratory procedure to pilot-plant processing led to the decision to terminate the work at this stage. However, the officials of the U. 8. Food and Drug Administration have empha- sized the hazards of toxic residues from insecticides and fungicides on fruits and vegetables. Most of the newer organic pest control chemicals are highly toxic and very low tolerances have been set, or in some cases no residue is permissible. Fish-oil compounds on the other hand are essentially nontoxic to humans. It is the opinion of the contractor that this fact will eventually counterbalance the relatively high cost and low activity of fish-oil derivatives, and that these may yet be develop- ed to compete with the new synthetic compounds for insect and fungi control, espe- cially for leafy vegetables and mature fruit. --BY CHARLES F.

This test is being further continued to see if the frozen fish can be held even longer in cold storage and still produce high- quality fillets. The East Boston Technological laboratory of the U. S. Bureau of Commercial Fisheries initiated this commercial-scale test in July 1957, to stimulate further interest in freezing fish at sea among vessel operators and shore-plant processors. The test is designed to acquaint the industry with the commercial-handling of fish frozen at sea, This test will also provide additional information on the length of time the whole and eviscerated fish can be held infro- zen storage, at a high level of qual- ity, prior to being processed into fillets. The latter point is of major importance in the practical com- mercial application of the freezing- fish-at-sea process, In July 1957, the Bureau's ex- perimental trawler Delaware re- turned to the Boston Fish Pier with 54,000 pounds of round and evis- cerated haddock that were brine- frozen at sea. The fish were glazed with fresh water during unloading and put directly into a cold-storage warehouse, Nineteen dealers inthe Boston area, who indicated a de- sire to take part in these tests, have been removing large lots of these fish from storage at bimonthly intervals. The fish are being thawed and filleted and the fillets packaged, refrozen, and mar- keted in the customary manner. VIEW OF THE BOSTON FISH PIER. A total of 36,000 pounds of the brine-frozen fish have been handled in this man- ner since the beginning of this study. Oral and written accounts of the observations made by the processors show that fillets prepared from brine-frozen haddock stored at 0 F. for 8 months, while slightly darker in color than fillets prepared from iced fish, are still of good quality. Examinations conducted at the Laboratory on similar samples of fish apparently substantiate these observations. The color of the brine- frozen haddock fillets, which is associated with the freezing process, was not con- sidered to be objectionable in marketing these fillets in the frozen fish trade. --BY JOSEPH W.

While 1957 was an excellent year, it was un- usual also to the extent that it was the best year for mackerel fishing in several years.

OOO 00 oi 0 10 A comparison of the landings of anchovies and mackerel for January 1 through May 7 this year with the same period in 1957 reveals that this year those fisheries are operating at a very low level. Table 1 shows the amount of tonnage loss, but when transposed to dollars the figures are even more Staggering. In the San Pedro-Long Beach area there are approximately 100 vessels engaged in the two fisheries at present, which means the average loss per vessel is about $11,423, which breaks down to somewhere between $700-900 per crew member de- pending on the size of the vessel. The packers also are greatly affected by this shortage, as they are faced with the loss of foreign markets which have been developed over the years. Anchovies are especially hard hit since the foreign markets for canned anchovies are relativelynew. Canned an- chovies did not gain ready acceptance, and were just at the point of becominga real factor in the Far East markets, when they disappeared. Both canned anchovies and mackerel are in heavier demand than usual, due to the sardine shortage this past season in Cali- fornia, but canners are not able to take advantage of the situation due to the shortage. In fact canners will probably lose many of the advances made during the last year in con- sumer acceptance of canned anchovies unless enough are packed to keep them on the shelf. The effect on fishermen has been exceptionally severe, as during the first quarter of the year no other species is available that can be substituted for anchov- ies and mackerel. In the latter part of May local bluefin tuna show up off Southern California, and the San Pedro fishermen receive some income from bluefin, but without mackerel and anchovies the normal earnings are upset. Therefore, this probably will be a poor year for the San Pedro-Long Beach purse-seine vessels. --A. D.

During the cruise, 27 tows with the 10-foot shrimp- mesh beam trawl and the 12-foot shrimp- mesh otter trawl yielded a catch of 33 male and 113 female dungeness crabs. The trip was planned to (1) determine the year-classes of the Dungeness crab (market crab) present in San Francisco Bay and in the ocean from Pedro Point to Bolinas Bay; (2) determine the size of the ''crabs-of-the-year" in these two areas; (3) determine the expediency of uSing the 12-foot shrimp-mesh otter trawl compared to the 10-foot shrimp-mesh beam trawl in crab sampling. The gear used was shrimp experimental gear consisting of a 10-foot beam trawl with a net of l-inch mesh. This net was fished with floats on the anterior portion of the (0 - Beam trawl drags a mouth.

This is the shoulder width, i. e. a caliper measurement just anterior to the most lateral spines. Preliminary inspection of the size frequency record of male crabs was made for groupings reflecting the age classes. This inspection was made with consideration of data from previous cruises. There were 4 and possibly 5 year-classes present. The fifth year-class appears as crabs over 190 millimeters in width; the fourth from 160 to 190 millimeters; the third from 130 to 160 millimeters; the second from 90 to 130 millimeters; and the first from 28 to 60 millimeters. The youngest crabs were very nearly one year old. Crabs in the first two years of life molt more than once per year, hence the gaps in the size distribution. This year-class breakdown was made for males only be- cause a different growth ratio for females has been observed in other studies. The sample of the first year-class (or crabs-of-the-year) numbered 28. These crabs were taken at stations 5 and 14 in San Francisco Bay and at stations 25 and 26 in the ocean (see chart). The crabs taken in the bay had an average size larger than those taken outside. Dungeness crabs of the same size range were taken by the beam trawl and the otter trawl. Thirty crabs were taken by the otter trawl and 116 crabs by the beam trawl. There was an average of 11.6 crabs per tow of the beam trawl and 10 crabs of the otter trawl. Over-all, 11.2 crabs were taken per tow. These figures were computed from the tows that contained crabs. Fourteen tows did not contain crabs. There was no difference in the selectivity of the two nets for different size crabs. Both nets are useful in collecting crab samples. The beam trawl is easier to handle with the manpower and gear on the Nautilus, a 50-foot research vessel. ok KOK OK 24 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 LOSS OF SPAWNING BEDS BELIEVED MAJOR FACTOR IN DECLINE OF KING source is loss of spawning beds, the March 1958 issue of the Department of Fish and Game's Outdoor California reports. At one time in the early history of the State over 6,000 miles of spawning streams were available to the king salmon in the Central Valley area. By 1928 the spawning streams had shrunk to 520 miles and at present consist of only about 300 miles. Dams which have cut off and flooded former spawning beds have accounted for most of this loss of spawning areas. This damage to the spawning streams of the Central Valley started with first miners who panned for gold in the Sierra foothills and it continues at present throughout the salmon and steelhead trout waters of the State. : A major factor on the north coast streams has been careless logging, which has destroyed or impaired about 1,000 more miles of spawning area. Salmon have an instinctive urge to return to their home stream. If they find it blocked or otherwise unsuitable when they come in from the sea, most of them will not seek out a substitute stream or spawning bed but will batter themselves to death or languish at the point of their frustration, dying without fulfilling their mission to replenish the stock. As the Department of Fish and Game sees it, the other factors responsible for today's plight of the salmon (not in order of importance) are: (1) Watershed damage, caused by mining, grazing, logging, agriculture, and forest fires. (2) Damage to spawning streams, caused by mining, logging, flood con- trol projects, gravel extraction, and highway construction. (3) Changes in water flow below dams, including actual drying of stream, temperature increase and man- ipulation of releases, stranding spawning nests and fish. (4) Water diversions for power, industrial processing, irrigation, domestic use, duck clubs, etc., which cause reduction or elimination of stream flow. (5) Pollution, which causes loss of fish and fish food and creates blocks to migration. (6) Poorly planned and executed artificial propagation in early days. (7) Predation and competition, including introduced spe- cies and changed conditions that favor predators. (8) Increased fishing pressure, sport and commercial, both in California and in the migration area to the north, coupled with increased fishing mortality of small fish and genetic downbreeding by selective fishing. OK OK KX YELLOWFIN AND SKIPJACK TUNA STUDIES OFF WEST COAST OF SOUTH AMERICA (M/V Southern Pacific Cruise 57C5-Tuna): A total of 1,230 yellowfin and skipjack tuna were tagged off the coasts of Mexico, Central America, Peru, and Chile by biologists of the California Department of Fish and Game aboard the com- mercial tuna clipper Southern Pacific during a 99-day cruise that ended on Febru- ary 11, 1958. The objectives of the cruise were as follows: (1) To study the popu- lation structure of the Eastern Pacific ''tunas'" by tagging yellowfin and skipjack tuna. (2) To field test two methods of securing the ends of ''spaghetti'' tags and to test a new dart tag. (3) To make collections of related marine life in baiting and fishing areas. (4) To make limited oceanographic observations. The 1,230 yellowfin and skipjack tuna were tagged with yellow type G (clamp), type G (knot), and dart tags, and released in the following areas: Southern Mexico, 32 yellowfin; Central America, 155 yellowfin and 27 skipjack; Peru Bank, 70 yellow- fin and 309 skipjack; North Central Peru, 115 yellowfin and 62 skipjack; Southern Peru, 1 yellowfin and 142 skipjack; Northern Chile, 63 yellowfin and 254 skipjack. June 1958 COMMERCIAL FISHERIES REVIEW 25 A total of 932 fish were tagged with "spaghetti" tags; 532 of this series were knotted in the standard way, while 400 were reinforced with 40-pound test mono- Mexics filament nylon cores and the ends se- cured by means of a small metal clamp. Although the clamp does not increase tagging speed, the nylon core gives a tag of superior strength. A total of 298 fish were tagged with experimental ''spaghetti'' dart tags. This tag could be applied faster than conven- tional "spaghetti" tags. (One of these dart tags was recovered before the com- pletion of the cruise.) The boat schedule and the areas fished did not permit extensive collecting of marine life. However, live-bait hauls produced 8 collections; night lighting, 16; examination of tuna stomachs, 9; and early morning deck inspections, 2. This material is presently being proc- essed.

The purpose was to: (1) To study, by tagging techniques, the migrations, ages, rates of growth, and other salient features of the eastern Pacific yellowfin tuna and skipjack populations. (2) Obtain biological and other information concerning "tuna" schooling habits, by sampling the size and species composition of individual schools. (3) Delineate ''tuna'’ spawning areas and seasons by collecting post larvae and ju- veniles under a night light. (4) Make routine biological and oceanographic observa- tions that may be related to the occurrence of ''tuna.'' (5) Collect marine organisms associated with ''tunas" in fishing areas and also on the baiting grounds with impor- tant live bait species. During the cruise, 134 yellowfin and 313 skipjack tuna were tagged and released at the following locations: off Costa Rica, 2 yellowfin; off Colombia, 18 yellowfin and 7 skipjack; off Peru (Peru Bank) 35 yellowfin and 95 skipjack; off Peru (14 Fath- om Spot), 72 yellowfin and 92 skipjack; off Northern Chile, 7 yellowfin and 119 skip- jack. Two skipjack tagged off Peru (14 Fathom Spot) were recaptured during the eruise and returned to the Terminal Island Laboratory. These two fish were re- captured in the release area after being at liberty for 15 and 22 days, respectively. 26 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 It was found that tagging speed could be improved by using plastic coated metal clamps to secure the two ends of the tags, particularly if properly designed pliers were available. Mexico Colombia TUNA TAGGING BY COMMERCIAL TUNA CLIPPER RUTHIE B (CRUISE 57-C-6-TUNA, NOVEMBER 12, 1957-MARCH 16 1958. Six yellowfin and five skipjack tuna were sampled for size and species com- position. These data indicate that "pure" schools, those consisting of a single species, tended to school by size. Schools of yellowfin tuna and skipjack mixed, however, sometimes contained several sizes of each. For example, one mixed school was made up of 4.5- and 7.5- pound skipjack plus 7.5- and 15-pound tuna. Fifty-six bottles of formalin-pre- served specimens, primarily obtained from night-light stations, are being identified and processed for ''tuna" larvae. Oceanographic and meterological observations were made throughout the cruise. There was no obvious relation- ship found between ''tuna'' catches and sea surface temperatures or between "tuna" catches and water clarity. Sea surface temperatures on the fishing grounds ranged from 18.0 C. to 29.5 C. Twenty packages of frozen speci- mens were obtained from bait net hauls, night-light stations, and by hook and line. These have been processed and individuals saved for future study at the laboratory or sent to other scientific institutions. Unusually poor fishing was encountered during the cruise. Poor fishing, in general, was experienced by the California tuna fleet operating in these areas.

Leffler said on March 20, 1958, in submitting to Congress a report opposing enactment of Senate bill S. 2719. The purpose of the proposed legislation is to provide for the payment of bounties for the control of certain predators such as hair seals and sea lions in the fisheries of the Pacific coast and Alaska. The Assistant Secretary stated that the U. S. Fish and Wildlife Service, backed by 40 years of experience, has found that bounties generally serve more as a means of harvesting an annual crop of the pest species being bountied, rather than as an effective measure of control of the predators. Under such a system, predators are taken where the task is easiest and least expensive, and not necessarily where their taking does the most good, he said. For many years the Alaskan Territorial Legislature has authorized bounties on hair seals along most of the southern coast of Alaska. More recently the bounty has been applied to hair seals in the Bering Sea and part of Norton Sound. Many thousands of dollars have been spent on these bounties, however, without any ap- preciable benefit to the salmon or other fishery resources. In preference to paying bounties, the Assistant Secretary declared that direct control measures which provide for the employment of professional hunters and trappers who concentrate their efforts in problem areas are much more effective and less expensive. In the Copper and Stikine River districts, for example, where hair seals prey on the salmon runs and also cause damage to fishing gear, the Alaska Department of Fish and Game has applied direct control measures which are proving to be far more practical than a bounty system. The U. S. Fish and Wildlife Service is now conducting a vigorous restoration program to rehabilitate the Alaska salmon runs. Studies are being carried on in cooperation with the Fishery Research Institute of the University of Washington to ascertain what effect hair seals, sea lions, and other predators have on the abun- dance of salmon. The Pacific halibut fishery is in a very productive condition, according to re- ports of the International Pacific Halibut Commission, and has yielded maximum catches in recent years. Assistant Secretary Leffler, in his report tothe Congress, pointed out that the Commission has never made any attempt to control halibut predators. Suen Great Lakes Fishery Investigations SEA LAMPREY LARVAE DESTROYED BY CHEMICAL: About a mile above into Lake Huron, a lamprey-killing chemical was fed into the 30-foot wide stream at a beaver dam to study effects on sea lamprey larvae. The treatment started 30 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 at 9 a. m. on April 15, and by 2 p. m. dead lampreys, most about four inches long, were beginning to appear downstream. The river was chosen because of its proximity to the Bureau of Commercial Fisheries Hammond Bay laboratory, where work against the lamprey has been un- der way for several years. The river was stocked with 500 brook and rainbow trout prior to the test. The chemical later made many of these fish groggy, but apparent- ly did not kill them. A similar test last fall on nearby Elliott's Creek showed the same results. Officials from a Michigan chemical firm, the Fisheries Research Board of Canada, and the U. S. Fish and Wildlife Service's Bureau of Commercial Fisheries coordinated efforts in this project. The work was aimed at ironing out difficulties in analysis of water samples and in use of the chemical. It was not designed as a full-scale management procedure. A full report of the work was not expected immediately, but it was obvious the chemical had harvested close to 100 percent of lampreys in the stream. Further work, both tests and management, is expected on Lake Superior streams later this year. Lake Superior still has a remnant lake trout population and officials are hope- ful the chemical will help save the remaining trout. Gulf Exploratory Fishery Program EXPLORATORY FISHING FOR RED SNAPPER WITH ROLLER-RIGGED OTTER TRAWL (M/V Silver Bay Cruise 7): The hard bottom areas 15-60 fathoms in the northeast Gulf of Mexico extending from the Mississippi Delta to 86 30' W. (south of Destin, Fla.) were fished with a roller-rigged otter trawl by the U. S. Bureau of Commercial Fisheries chartered exploratory fishing vessel Silver Bay during a March 1958 cruise. The primary objective was to dis- cover if red snappers could be found incommercial quantities on bottom too rough for otter trawls. Red snapper were taken in small quantities in 20 of the 44 tows made with the roller-rigged trawl. No areas were found which produced red snapper in commer- cial quantities. Several attempts at fishing on or adjacent to known red snapper "lumps" resulted in tear-ups, but no gear was lost. The trawl functioned without mis- hap on some rough bottom areas avoided by local commercial trawlers. M/V SILVER BAY (CRUISE 7, MARCH 11-28, 1958). A series of tows on broken bottom south of Mobile Bay in 20-35 fathoms yield- ed catches of mixed species of up to 3,000 pounds per 90-minute tow, using a roller- rigged trawl constructed of 43-inch braided nylon. The principal species caught were croaker (Migropogon), spot (Leiostomus), porgy (Stenotomus), and white sea trout (Cynoscion). x KOK OK Jvne 1958 COMMERCIAL FISHERIES REVIEW 31 MIDWATER TRAWLING EXPLORATIONS BETWEEN MISSISSIPPI DELTA AND CAPE SAN BLAS (M/V Oregon Cruise 8): Samples of fish ranging from 10 to 1,369 pounds were obtained in 36 midwater tows by the U.

Fifty- iy two exploratory midwater trawling tows were made between the Mississippi Del- ta and Cape San Blas during the cruise to count, sample, and identify midwater fish schools and to test midwater trawls of varying mesh sizes. Trawl sets were made on depth re- corder indications of midwater schools and the samples obtained indicated con- : centrations of many species of clupeoids. || “ a Eighteen of the schools sampled were laaiee vs wa Cis | predominantly razorbellies (Harengula ONG ‘ Baie pensacolae) and nine were 5 to 6 inch anchovies (Anchoa hepsetus).

Menhaden (Brevoortia patronus) made up the bulk of the catch in two tows off Pass a Loutre. One tow (January 30) contained 1,290 pounds of menhaden in ripe spawning condition. ot TMs | | Leceno: * | @- SUCCESSFUL MiDWATER | RAWL STATION. COVERED BY SCHOOLS.

A single set on three dense school indications ath an 88-foot nylon trawl resulted in the loss of all the netting. Recorder indications of subsurface schools were numerous both preceding and following the cold wave during the middle of February. Schools were noticeably diminished during the cold wave. King Crab BUREAU FISHERY BIOLOGISTS STUDY LIFE HISTORY: Literally foot by foot the king crab utilizes its six walking legs to wend its way here and there in its fa- vorite habitat in the Bering Sea and in other places in the North Pacific Ocean where the water is from 30 to 70 fathoms deep. Records in the U. S. Bureau of Commercial Fisheries show that this crustacean has migrated along the ocean floor as much as 300 miles. Migrations of 50 to 100 miles are common. Recently the Bureau reported that one king crab was taken 122 miles from point of release, one year and ten days after tagging. The king crab, a walker and not a swimmer, is one of Alaska's many contribu- tions to the tables of many nations. In the eastern Bering Sea, which is the center of United States interest and activity, there are an estimated 20 million commercial- size king crabs. This estimate is based upon a July 1957 sampling project at 77 fishing stations covering an area of 31,000 square miles of ocean north of the Alas- ka peninsula. 'Commercial size" is not less than 62 inches across the top of the 32 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 body. The king crab often measures as much as 5 feet from leg tip to leg tip; it weighs usually from 7-10 pounds with a record weight of 22.3 pounds. While its tastiness has long been known to the United States consumer, it is only in recent years that United States fishermen have made systematic attempts to harvest the resource. Much of harvesting can be done in "off seasons" when fishing boats are not otherwise engaged. Japan has been harvesting the king crab for a long time. With United States fishermen now becoming active in the harvest, the advantage of joint conserva- tion practices is becoming ap- parent. Hence, the United States section of the International North Pacific Fisheries Commission has asked the Bureau to make as thorough a study as possible of this resource. Through the Saltonstall-Kennedy Act of 1954 for the improvement of the dom- estic commercial fishing industry, KING CRAB $31,000 has been made available for the current research program, in addition to $39,000 of regularly-appropriated funds. If the resource is to be managed properly (that is if maximum sustained yield is to be realized) the researchers must accumulate a considerable amount of data on the life history of that shellfish--its spawning habits and areas, its natural en- emies, conditions of optimum development, strong and weak spots in the life cycle, the rate of growth, its habitat, andnumerous other things. The basis of such a study depends upon being able to identify individual members of the popu- lation to be studied. One of the toughest problems which the research biologists working on the king crab have been asked to solve is the matter of tagging. Because the king crab peri- odically just walks out of his old shell a tag attached to the shell sooner or later is separated from the crab. But the biologists finally found a spot under the shell--in an area which in hu- mans might be called the sacroiliac--where a ''spaghetti'' or ribbon tag can be permanently attached. Last year 15,570 king crabs were tagged. Information on their recapture is secured from both Japanese and United States fishermen. OK ok ok Ok STUDIES ae BE CONTINUED BY ALASKA FISHERIES BIOLOGIST IN KODIAK- ery biologist aio recently joined the staff of the Alaska Department of Fish and Game, that agency's Director announced in April 17. The biologist will continue king crab research, which was started in the Kodiak- Afognak area in 1954 bythe Alaska Department of FishandGame. The Department's former biologist made an important contribution to the study of king crabs--the de- velopment of a tag that would stay on the crab after its shell was shed during molting. Since then the tag has been widely used by other fishery agencies engaged in king crab research, June 1958 COMMERCIAL FISHERIES REVIEW 33 Working in close cooperation with fishermen and processors, the biologist will continue the Department's tagging program for additional data on king crab growth and migrations. These studies have been greatly facilitated by the installation of a large marine aquarium by the Department, which is now inoperation at Kodiak. This will enable the biologist to conduct controlled experiments on growth and molting. "The king crab fishery," the Department's Director says, "has expanded into a most important industry and gives promise of surpassing salmon in the Kodiak area in value to the Territory." Kodiak now calls the city ''The King Crab Capital of the World" and plans to stage an annual king crab festival. Maine Sardines CANNED STOCKS, APRIL 1, 1958: Distributor's stocks of Maine sardines to- taled 293,000 actual cases on April 1, 1958--2,000 cases or less than 1 percent low- er than the 295,000 cases on hand April 1, 1957. Stocks held by distributors on January i, 1958, amounted to 230,000 cases, and on November 1, 1957, totaled 298,000 cases, according to estimates made by the U. S. Bureau of the Census. Canners' stocks on April 1, 1958, totaled 476,000 standard cases (100 32-o0z. cans), 11,000 cases above stocks held on the same date last year, and consider- ably less than the 1,111,000 cases reported on hand on January 1, 1958. Shipments of canned Maine sardines from April 15, 1957, to April 1, 1958, a- mounted to 2,067,000 standard cases as compared to 1,877,000 cases for the same period the previous season.

The action was taken, at the request of the industry, after three years of extensive research and actual experi- ence on a voluntary basis withthe Commissioner’s organ- ization participating in the development phases. Under the program all lots of quarter-oil (34 oz.) Sardines packed in the future will be graded, under the State’s supervision, and given a rating commensurate with the degree of quality produced. It further provides for the issuance of official State cer- tificates of grade to any packer who requests this service and eliminates the introduction into trade channels of any Sardines that do not conform to minimum standards. Each lot will be rated either fancy, extra-standard, standard, or substandard, according to the manner in which it survives the rigid grading examination. The Commissioner saidthat research was being con- ducted for the inclusion of mustard and tomato-sauce packs, along with the oil pack, at a future date. Maine sardine packers produce a large share of the world’s sardines with an annual pack of approximately 2,225,000 cases (100 cans to the case). The Chairman of a Maine sardine industry committee which has been active in development of the program, 34 COMMERCIAL FISHERIES REVIEW described the promulgation as ‘‘the most commendable and progressive move ever made by any segment of the American seafood industry, on its own initiative....’’ He predicted that it would have far-reaching effects towards improvement of the per capita consumption ratio and mar- keting of Maine’s sardine pack. Administration of this activity comes under the Maine Department of Agriculture, as that Department is charged Vol. 20, No. 6 by law, with the responsibility of policing and enforcing all State regulations dealing with grading, inspection, growing, and processing of foodstuffs. Much work along these lines is now being done on poultry, potatoes, blue- berries, eggs, milk, and other products. The grading operation will be performed by employees of the Department of Agriculture, under the direct super- vision of the Assistant Chief of Inspection, atthe industry’s Bangor Laboratory. Samples of each lot packed will be taken daily by State Inspectors, stationed at the individual plants, and shipped directly to the laboratory. The examinations and testing will then be speedily carried out so as to eliminate any unnecessary delay in getting the reports of the results back to the canners, Grades will be based on a number of factors, including appearance, texture, flavor, odor, oil or sauce quality, moisture, and water content. The Department will take over a number of graders who have been training for this work for three years. The laboratory was established and equipped with Maine Sardine Council funds at a cost of more than $75,000 and was Officially opened by the Assistant Secretary of the Interior Ross L, Leffler two years ago. Previously the development work was carried on at a laboratory on the University of Maine campus. In addition tothe grading and quality control program, the laboratory houses other sar- dine research activities. Activities that finally resulted in the official grading were launched in 1952 when the U. S. Bureau of Commercial Fisheries was engaged to conduct pilot studies. Prior to promulgation the Commissioner presided at a public hearing, which was attended by most of the Maine’s sardine canners, and an outline of the plan of action was received by the group without opposition. PACKING SEASON OPENED ON APRIL 15, 1958: The 1958 Maine sardine pack- ing season legally opened on April 15, 1958, but industry leaders predict that pro- duction will not begin until late May or early June. The Maine Sardine Council's Executive Secretary said that the mid-April open- ing date has been nothing more than a legal definition for the past ten years. Not only have the old time early runs of fish failed to show up, but none of the plants are ready for operation so early. He said that there was nothing to indicate whether there would be an abundance or scarcity of fish this season, but if the trend since 1951 prevailed, the latter situ- ation might be the story. Starting with 1951 when fish were very scarce, all season the industry had al- ternate high and low production years until 1956 and 1957 which were two good fish years ina row. Unless the trend is broken a shortage of sardines could crop up again. It was expected that several less plants would be in operation in 1957. Two plants have been dismantled and there are reports of others not planning to operate. The industry is anxious to know just what effect recently-promulgated official Maine State grade standards will have on the pack and the market picture. June 1958 Marke EDIBLE FISHERY PRODUCTS MARKETING PROSPECTS, SPRING-SUMMER 1958: United States civilian consumption of fishery products in the next few months is expected to be about the same as a year earlier. Average retail prices of these products this spring, judging from Bureau of Labor Statistics wholesale prices, may top the year-earlier high levels. Commercial fishing operations are now on a seasonal upswing which will continue until early or mid-summer. Weather permitting, landings of food fish and shellfish may be heavier this spring than last since the level of prices may encourage commercial fishermen to make more trips, espe- cially for groundfish. Stocks of fishery products in cold storage in the continental United States last winter--partic- ularly groundfish fillets and blocks--were rather low in volume and high in price. The seasonal to ee North Atlantic Fisheries Explo CONTINENTAL SHELF OFF THE CA COMMERCIAL FISHERIES REVIEW 35 ting build-up in storage stocks which begins in the spring may be a little heavier this year than last. Imports of fishery products during the next few months will be a little larger than a year earlier if supplies are available abroad. ‘In the past year world supplies of groundfish fillets and blocks, important items in international trade in edible fishery products, have been relatively tight. Some reduction in exports from the spring 1957 total is likely since our supplies of canned fish are much smaller this year. This analysis appeared in a report prepared by the Agricultural Marketing Service, U.S. Department of Agriculture, in cooperation with the Bureau of Commercial Fisheries, U. S. Department of the Interior, and published in the former agency's May 2, 1958, release of The National Food Situa- tion (NFS-84). rina ration and Gear Research ROLINAS SURVEYED FOR COMMER- CIAL FISH (M/V Delaware Cruise 58-1): Concentrations of commercially market- able fish were not common in the offshore Continental Shelf areas off North and South Carolina surveyed from February 23 to March 17, 1958, by the U.

A single common mackerel (Scomber scombrus) was takenten miles SE. of Cape Lookout in 20 fathoms. Considerable scientific data on sharks was ob- tained during the cruise. One specimenofadeep-water shark (Deania sp.), reported previously only from the Eastern Atlantic, Pacific, and Indian Oceans, was taken, and the second known specimen of the deep-water shark Etmopterus bullisi was captured. Over 200 specimens of the sand bar shark (Eulamia milberti) were taken on one tow south of Cape Hatteras, indicating that this area may be the winter - ing area for this species. Bottom traces were indicated in many areas with the echo-sounder, and from all indications anchovies may have been the species contributing to these traces. Asin previous exploratory operations in this area, the bottom was found to be trawl = able, with gear damage ononly 10 stations; aseveresnagat 33 27' N. latitude and 77 04' W. longitude resulted in loss of port trawl door and the No. 41 net with roller gear. Four oceanographic transects (see charts) were made to investigate the occur- rence of warm bottom water along the edge of the Continental Shelf, south of Cape Hat - teras. This condition was checked with reversing bottom thermometers and bathythem- ograph casts. As indicated by data collected by the Woods Hole Oceanographic Institu- tion, the bottom water was considerably warmer in adepthof 75 fathoms than it was either inshore or offshore. A more tropical fauna was found to be present in this area, as several species of butterfly fish and southern forms of rays were taken. Kiet North Atlantic Fisheries Investigations HADDOCK ECOLOGY STUDIES CONTINUED (M/V Silver Mink): Observations and collection of data for the haddock ecology study were conducted by the Bureau of Commercial Fisheries chartered vessel Silver Mink on April 11, 1958, in an area NNE. of Cape Cod Light, Mass. Two tows were made with an otter trawl having a 13-inch mesh cod end liner at 55 to 65 fathoms. The area fished was approximately six square miles. One bathythermograph lowering was made during the trip. The entire catch of 764 haddock were measured for length, and scale samples were collected from 153 fish. In a sample of 50 female and 50 male haddock, length and weight were collected; liver weight and state of development noted; drumming muscle length, weight, and color were recorded; and scale samples, fin rays, and stomach contents collected. All species were identified and counted in one tow and important species were measured. A sample of sea dabs was collected for age and growth studies and red (ling) and white hake for meristic studies. Red hake predominated in the two tows, followed by sea dabs, haddock, and dogfish. An increased abundance of one- and two-year old haddock was noted. About all the haddock taken in the catches were spawned out, indicating that the peak of spawning had occurred about the end of March. kK KK HADDOCK TAGGING AND HYDROGRAPHIC CRUISE COMPLETED (M/V Al- batross III): Thirty-two otter-trawl tows were made on Georges Bank, Browns Bank, and Jeffreys Ledge by the U.

This was the first in a series of shrimp explorations scheduled for the Bureau's vessel for 1958 off the coasts of Washington and Oregon in cooperation with the State of Washington Department of Fisheries and the Fish Commission of Oregon. The area explored during this trip extended from 10 to 28 miles offshore be- tween the entrance of the Columbia River and Cape Falcon. Although tows were made at depths of 56 to 94 fathoms, the most productive grounds were found in 70 to 85 fathoms on green mud bottom. 38 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Of the 63 tows (nearly all of 30-minute duration) completed during the trip, 43 were made with the 40-foot trawl and 15 with the 72-foot trawl. Both trawls were constructed with 13-inch mesh cotton netting. Indications are that the 72-foot trawl is approximately twice as efficient as the 40-foot trawl. The bottom fished was excellent with net damage limited to a single tow. Mud was present in the net on only one occasion, and even then it was only a small a- mount. Samples of shrimp were frozen from each tow for biological analysis at the Fish Commission of Oregon's Research Laboratory at Astoria. Considerable fish- ing time was lost because of adverse weather conditions. The second of the 1958 series of shrimp explorations off the coasts of Wash- ington and Oregon was started on April 28 and due to end on May 23, 1958. The ob- jectives of this cruise (No. 37) were to determine the distribution of shrimp off- shore from Willapa Bay, Wash., to the Columbia River and from Cape Flattery at the entrance to the Straits of Juan de Fuca to Destruction Island off the northern part of Washington. kK KOK MODIFIED ELECTRICAL DEPTH-TEMPERATURE TELEMETER TESTED AND TRUE COD TAGGED (M/V John N.

Cobb during a two-week cruise to the eastern part of the Strait of Juan de Fuca. The cruise end- ed on February 28, 1958. In ad- dition to testing the telemeter, Washington Department of Fish- eries biologists aboard were as- sisted in tagging true cod. More than 1,100 true cod and about 100 sablefish (black cod) were tagged during the cruise by the biologists with plastic "spaghetti''-type tags and experimental dart tags. THE JOHN N.

A total of 54 bottom tows were made with a standard 400-mesh Eastern-type otter trawl between Port Townsend and Port Angeles at depths of 10 to 60 fathoms. True cod were found to be most plentiful off Port Townsend, but small catches were made of Port Angeles and west of Protection Island. The depth-temperature telemeter, a device which transmits continuous trawl depth and water temperature data to the pilothouse through an electrified trawl cable, proved to be sufficiently accurate when operating. However, on several oc- casions the electrical conductors broke under the strain of towing, necessitating repairs aboard the vessel. The tests proved that a stronger type of termination for the sending unit will have to be developed if this instrument is to become a de- pendable aid in bottom trawl fishing. Sasa June 1958 COMMERCIAL FISHERIES REVIEW 39 Oregon COMMISSION OPPOSES MOVE TO DECLARE STEELHEAD TROUT A GAME FISH: The Oregon Fish Commission, at its April 1958 meeting in Portland, unani- mously went on record as being officially opposed to declaring steelhead a game species in Oregon waters. The Commission members viewed with particular dis- favor and alarm a movement currently under way to place the steelhead issue on the No- vember 1958 ballot. Speaking on behalf of the Commission, the Chairman de- clared that after careful con- sideration of the many complex factors associated with the steel- head question, the Commission decided it had no alternative but to oppose the game fish measure. He stated, ''We fail to detect any semblance of conservation involved in making steelhead a game fish in Oregon. To the contrary, enactment of the proposal being advanced would result in either a tremendous wan- ton wastage of highly palatable fish or complete abolition of commercial fishing in the Columbia River.'' He further stated that he could not see how either of these drastic consequences could be construed as sound conservation. Elaborating on the reference to wastage, the Chairman said that the manner in which gill-net fishing has been conducted in the Columbia River for more than 100 years makes it impossible to fish for salmon without catching varying numbers of steelhead. He also said that the major share of salmon and steelhead taken com- mercially in the Columbia River are dead or severely injured when the fisherman pulls his net. He continued, ''Under provisions of the proposed initiative, a com- mercial fisherman would be heavily fined for catching even a single steelhead either intentionally or by accident. You can't educate a steelhead to stay out of a net, and we fear that large quantities of dead or dying steelhead that inevitably would be caught would be thrown overboard." The Chairman further stated that Oregon law prohibits the wanton wastage of both food and game fishes, which precludes any disposal of steelhead caught inci- dentally during a legitimate salmon fishing operation in the Columbia River except through established commercial channels. The State of Washington recognizes this fact and permits the commercial fishery and disposition of steelhead in the Colum- bia River district and actually collects a fee on the quantity of fish landed. Citing the Oregon commercial fisheries code, he said that the Commission is obliged to manage the food fishery resources of Oregon on the basis of conserva- tion, substantiated by investigations. ''Scientific findings of our staff of highly qual- ified biologists indicate that Columbia River steelhead runs are in good condition." he stated. "All available evidence indicates that with continued proper management, these runs can maintain a sizable harvest by both sport and commercial fishermen. For all practical purposes, making steelhead a game fish in Oregon involves only the Columbia River. An initiative measure adopted in 1956 reserves all Oregon streams south of the Columbia River, except Tillamook Bay, for exclusive use by sport anglers as far as salmon and steelhead are concerned. A limited commer- cial fishery is still permitted for chum salmon in Tillamook Bay." In conclusion, the Chairman of the Commission declared, 'Both sport and com- mercial interests have suffered materially over the years as a result of these con- tinual fish controversies that all too often have been based more upon emotion 40 COMMERCIAL FISHERIES REVIEW Vol. 20. No. 6 rather than fact. It is lamentable that the energy generated by these conflicts has not been directed towards assisting our capable fisheries scientists in solving the very real problems of maintaining and increasing salmon and steelhead production in our streams." Pacific Oceanic Fishery Investigations ENUMERATION AND SAMPLING OF TUNA SCHOOLS IN THE MARQUESAS ISLANDS AREA (M/V Charles H. Gilbert Cruise 38): Sampling Tuna Schools: Ob- servations made by the U. S. Bureau of Commercial Fisheries research vessel Charles H. Gilbert indicate that April is a transition period be- tween the seasons of abundance and scarcity for skipjack tuna in the Marquesas Islands area. In the course of an 85-day cruise that ended on May 2, 1958, the Charles H. Gilbert explored the waters around the Marquesas Islands, Tuamotus, and as far south as Tahiti (French Oceania), and reported that skipjack were plentiful in those waters. Skip- jack in the Marquesas area were uniformily small in size, meas- uring around 5 pounds, while fish farther to the south in the Tuamotua and Tahiti area were generally large fish, 15 to 20 pounds, and comparable in size to the Hawaiian season fish. M/V CHARLES H. GILBERT Of the total of 183 schools of fish sighted on the cruise, 61 schools were identi fied as skipjack tuna, 4 as yellowfin tuna, and 11 as mixed yellowfin and skipjack. The balance were unidentified. Morethan 1,300 skipjack were tagged, with a new plastic dart tag develaped by the local laboratory, and released. Recapture of these tagged fish will provide valuable information on the movements of fish in French Oceania. The Marquesas Islands are located about 2,000 miles southeast of Hawaii and 2,800 miles from the United States mainland, thus placing them within an exploit- able distance of United States commercial fishermen, particularly the long-range segment of the West Coast tuna clipper fleet. The vessel surveyed these virgin waters by visual scouting and live-bait fish- ing. The Marquesan sardine, a bait fish presently being introduced into Hawaiian waters by the U. S. Fish and Wildlife Service, was found to be an excellent bait for skipjack. Although rather large when compared to the local skipjack bait, the nehu, even the small skipjack of the Marquesas area were found to respond favorably to it. The vessel brought back 25 buckets of Marquesan sardines and released them off Ewa, making a total of about 55,000 fish of this species that have been released in Hawaiian waters. About one-half dozen sardines were taken by the sampan Buc- caneer on May 1 in West Loch, Pearl Harbor, just prior to the most recent stock- ing. While these fish were probably survivors of earlier plants, they could have been progeny of spawnings. June 1958 COMMERCIAL FISHERIES REVIEW 41 Inshore Surveys: Two standardized inshore surveys, near the Marquesas Is- lands, were conducted during the cruise. The first survey, February 27 through March 8, revealed an abundance of skipjack schools in the area. Of the 90 schools sighted, 24 were identified as be- ing composed of skipjack. Others were 3 yellowfin, 6 mixed (skip- |) jack and yellowfin), and 57 uniden- tified schools. Many of the schools were large and attended by huge bird flocks. The skipjack were al- most without exception small (4- 8 pounds), and yellowfin were gen- erally between 15 and 20 pounds each in weight. The second inshore survey, conducted between April 11 and 19, resulted in fewer sightings. Of 54 schools seen, 19 were skipjack, 4 were mixed (skipjack and yellow- fin), and 31 were unidentified. Like the first survey, the fish were LEGEND: generally small.

This survey again revealed the absence of large skipjack in this area as without exception the fish seen or taken were around 5 pounds in size. The Marquesan sardine (Harengula vittata) was generally scarce during the period of this cruise, particularly prior to mid-April. The previously reliable baiting grounds in Taiohae Bay, Nuku Hiva, yielded only a few scattered groups of sardines, while other bays in Nuku Hiva such as Taipi Vai and Anaho were notable for the absence of this bait fish. Surveys were made in all likely bays in Nuku Hiva and the general scarcity of bait was noted. Beginning around April 10 the sardines begar to show up in fair quantities in Taiohae and Tai Oa Bays in Nuku Hiva. 42 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Prior to April 10, a total of 40 sets were made in Nuku Hivan bays resulting in 218 buckets of sardine or 5.4 buckets per set. After April 10, 13 sets took 167 buckets or 13 buckets per set. Moreover, about 30 additional visual sweeps prior to April 10 showed no bait present in most of the bays surveyed. Indicative also of change in the bait situation after mid-April was the appearance of sardine at nights around the ship's light where formerly few or none had been attracted. Of the other islands surveyed, only one bay in Tahu Ata Island (Hana Tetou) was found to have a fair quantity of sardines during this cruise. Unfortunately, the long haul from the baiting site to the vessel was probably the chief cause of the very high mortality experienced with bait taken in this locality. The size frequency, sex, and gonad development were recorded from about 25 sardines at each baiting locality. An additional sample was preserved for labora- tory examination. A non-quantitative 10-minute plankton tow was made at each baiting locality employing a 45-cm. net. Visual Surveys into the Tuamotus: Two days were spent fishing and scouting in the Tuamotus. Most noteworthy was the predominance of large (15- to 20-pound) skipjack in this area. Diurnal Variability of Zooplankton: The diurnal variability station was occupied twice during the cruise. Each consisted of a 24-hour series of bathythermographs and 140-meter plankton tows taken at 2-hour intervals. Deep-Swimming Tuna Resources in Equatorial Waters: A series of 7 long-line stations along 150° W. longitude between 5 N.andI1 = S. latitude resulted in poor catches; the best day's catch was 8 yellowfin (3° N.). One big-eyed and 7 yellowfin tuna taken by long line were tagged and released. Environmental Monitoring Survey in Waters Adjacent to Oahu: The Oahu mon- itoring survey, consisting of bathythermographs and collection of surface salinity samples at 12 localities, was conducted at the beginning of the cruise. General Observations: Various oceanographic and productivity measurements were made during the cruise including 336 bathythermograph lowerings, 233 sur- face salinity samples, 204 phosphate samples, 14 Secchi disk and Forel observa- tions, 71 0-140 m. oblique zooplankton and larval fish tows, and 12 surface plankton tows. Blood samples for serological studies were obtained from big-eyed tuna (long- line caught) and skipjack. Salmon BIG FIELD TEST FOR ELECTRICAL GUIDING OF about seven years. It is the Bureau’s first large-scale YOUNG FISH: A full-scale field experiment on the effec- tiveness of electrical apparatus in guiding young seabound salmon away from danger areas was begun in March 1958 and continues throughout the period of migration, the U. S. Bureau of Commercial Fisheries announced recently. The tests were started at Lake Taps on the White River, a tributary to Puget Sound, Wash. The project is a result of the electrical guiding experi- mental program which the Bureau has been conducting for test on the use of electrical equipment to divert young fish from danger areas. Two field tests on streams approximating 100 feet in width have been successful, as have numerous laboratory and aquarium tests. In the current test a 1,000-foot elec- trical fence will be used. A ‘‘fence’’ consists of a line of electrodes which hang in the water at specified intervals and which carry pulsating direct electric current supplied by a source on the shore.

A niacin deficiency has been proved to be correlated with the sunburn, and research men are delving deeper to deter- mine the character of this relationship. Since circumstances--high dams and the destruction of salmon runs and spawning grounds--make successful hatch- ery operation a most important activity for the continuance of the Columbia River salmon fishery, biological attention Sain ke is being given to sunburn and to kindred conditions associated with light. Sunburn in salmon being reared in the Bureau's fish hatcheries in the Pacific Northwest is as noticeable on the fish as sunburn is on human beings. Distinct dis- coloration, a dermatitis causing sloughing off of the epidermis (which on a fish is under the scales), and swellings and lesions on the back are some of the evidences. Salmon fry and small fingerlings also show evidence of the adverse effect of sun, or at least excess light. The death rate of young salmon being raised near sunny windows is much higher than in portions of the same brood raised farther back in the hatchery. The same thing applies to eggs. The hatch of salmon eggs kept in an area of sunlight is smaller than from eggs kept in darker portions of the room, Experiments conducted by the Bureau's nutrition laboratory at Cook, Wash., indicate that diets deficient in the vitamin niacin are correlated with sunburn in salmon. Fish fed a niacin-deficient diet for 30 days have developed serious sun- burn. Sunburned fish fed a complete diet for 60 days under the same light con- ditions have shown almost complete recovery. Further and more complete experi- mentation and analysis are planned for this spring. Trout are also occasionally afflicted with "sunburn" in hatcheries, particular- ly in the states of the Southwest. Recognition of the cause will have far-reaching benefits in these areas, as well as in the salmon restoration program. Fish in the wild, of course, are protected from sunburn by stream cover, deep pools, and a niacin-rich diet. Shad RECEIPTS AND TRENDS ON NEW YORK CITY'S FULTON FISH MARKET: from a low of 1.4 million pounds in 1953 to a high of 2.9 million pounds in 1948 (see table 1). Shad receipts in 1957 dropped to 1.8 million pounds--22 percent be- low the 2.3 million pounds reported in 1956, 44 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Most of the shad came from New York and New Jersey (Hudson River) during April and May and from Georgia, North Carolina, Virginia, and Maryland during Table 1 - Shad Receipts on New York City's Fulton Fish Market, 1948-1957 (OH NH BAI & wo © January, February, and March. Wholesale prices for shad report- ed in New York City's Fulton Fish Mar- ket for April 1955 and April 1957 are shown in tables 2 and 3. Experienced observers in New York City's Fulton Market have noted a steadily diminishing demand for shad as a source of fish meat, but a firm and active market exists for the shad roe. As shad meat is richly-flavored and requires more than ordinary skill in cooking, it is understandable that the younger generations look for more easily-prepared fishery products. Annually the drop in shad prices during the season corresponds very closely to the peak of the run of shad to the Hudson River and, as a rule, this is the time when the shad eating public begins to lose interest in this variety. of 0 USO fF 0 eA Oo 0 There are several other factors that affect shad prices at New York. Although New York City is an excellent market for the shad roe, the market for shad meat is poor; there- fore, when the supplies of buck shad are heavy there is no market at all in New York and the New York dealers will consign buck shad and "'cut'' roe shad to other cities ata loss. The profits from the shad roe will usually make up the losses and yield a profit. With New York City loaded up with buck shad and cut roe shad and ready to sell yoreoropet peer ros orirtiori ning at low prices, the prices paid for Maryland and Virginia bucks are forced down- ward. As a rule after the middle of April all East Coast shad markets become over- supplied with shad. Also, as the roe shad from the Hudson River become more mature they are less valuable as a source of roe. June 1958 COMMERCIAL FISHERIES REVIEW 45 These adverse factors have been apparent for years, but they seem more pro- nounced in recent years due to a slowly-diminishing market for shad as a source of fish meat. Table 3 - Daily Shad Prices Reported in New York ty Market News Service "Fishery Products Reports," April 1957 Another tactor which has had an ever-increasing effect on shad prices at New York City is the contamination of Hudson River shad with oil and other waste prod- ucts. At times perfectly fresh shad are so contaminated with oil that they are un- salable as a source of shad meat. The public has become increasingly conscious of this oily flavor in Hudson River shad. Still another factor to be considered when judging the market and price for shad is the unusual difficulties encountered in preparing shad meat for the table. Modern consumers are extremely conscious of fish bones and shad have many very fine bones. The methods of boning shad are good, but costly in terms of labor. This practice of boning shad has been one factor that has helped to maintain the market for shad, but fish cutters who make good shad-boners arescarce. The seasonal nature of the fishery tends to keep skilled fish cutters out of the shad-boning business. Shrimp GOOD CATCHES TAKEN OFF TAMPA BAY, FLORIDA: Sizable catches of Gulf shrimp were taken from waters close to the mouth of Tampa Bay during the last half of April 1958, the U. S. Bureau of Commercial Fisheries fishery market- ing specialist at Tampa reported on May 1. The shrimp catches are the first taken from waters close inshore in this area since 1954. Catches weighing close to 3,000 pounds were taken by many of nearly 70 trawlers working the area. A trip usually consists of from 3-5 days, with all trawling done at night. The current shrimp run began when several Fort Myers shrimpers trawled ex- perimentally in the area west to north west of Egmont Key. Shrimping has been best from the entrance to Tampa Bay to off Blind Pass at St. Petersburg Beach, about 12 miles north. The best shrimp catches were taken 3-5 miles offshore at depths of 18-42 feet. In the past shrimp boats operating out of Florida west coast ports have seldom found shrimp in commercial numbers in the Tampa Bay area. Past shrimp runs close by have usually faded within a short time or been abandoned in favor of better 46 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 fishing elsewhere. Best known west coast Florida shrimping grounds are in the Tortugas area, near Key West, and off Fort Myers Beach. Tampa is a major base for seagoing vessels which cross the Gulf to shrimp on the Campeche grounds off the Mexican coast. Shrimp is the number one dollar-value fishery in the United States and a multi-million dollar business in Florida. (Sb SS United States Commercial Fisheries Decline in 1957 The U. S. Bureau of Commercial Fisheries' preliminary review of the United States commercial fisheries for 1957 shows a decline in the landings, a decline in the pack of fish used for human food, an increase in the canned pet food pack with fish as an ingredient, a decline in the number of fishing craft used, a decrease in the number of fishermen, and a slight increase in the number of shore installations handling the products. The per capita consumption remained steady at about 10.2 pounds. LANDINGS: The United States landings for 1957 were 4.75 billion pounds as compared with 5.25 billion pounds in 1956. (The data on quantity represent fish in the round or as landed except for mollusks which are reported in pounds of edible meats instead of weight in the shell.) Declines were noted in both the food fish and industrial fish landings. Menhaden (the chief industrial fish) landings were down 20 percent, or 400 million pounds, and were responsible for the lower landings in this group. The 1957 catch of industrial fish was 2.2 billion pounds as compared with 2.6 billion pounds in the previous year. The food fish catch dropped from 2.7 bil- lion pounds to 2.5 billion pounds. Among the species taken in smaller quantities in 1957 were cod, haddock Pa- cific halibut, Atlantic ocean perch, salmon, tuna, oysters, and shrimp. The catch of herring, flounders, mackerel, pollock, scallops, and lobsters was up somewhat while the 40.6-million-pound Dungeness crab harvest and the whiting catch of 132.8 million pounds established new high records. EMPLOYMENT AND VESSELS: The fishing boats were manned by 142,000men, down 2,000 from 1956; in the shore establishments, estimated employment was 100,000. The estimated number of boats used in the commercial fisheries totaled 84,000. EX-VESSEL PRICE AND VALUE: The average ex-vessel price for the 1957 landings was 7.39 cents a pound as compared with 7.03 cents a pound for the 1956 landings. But because of the decreased catch, the total value of the 1957 harvest was below that of 1956. The following figures show the estimated values of the 1957 catch at the various trade levels with 1956 values in parentheses: producer (fish- erman)--$351,000,000 ($369,018,000); processor--$592,000,000 ($622,000,000); wholesaler--$836,000,000 ($879,000,000); retailer--$1,091,000,000 ($1,147,000,000). LEADING PORTS: San Pedro, Calif., continued to be the Nation's No. 1 port in both landings and ex-vessel value of landings; the 354.4 million pounds of princi- pally tuna, mackerel, and sardines brought $25.4 million ex-vessel. Lewes, Del., was second in landings with 286.2 million pounds of menhaden, and Reedville, Va., was third with 256.8 million pounds of menhaden. Gloucester, Mass., was fourth in total landings, but second in landings of food fish with 248.9 million pounds. Other important ports included Beaufort-Morehead City, N. C.; Boston, Mass.; San Diego, Calif.; New Bedford, Mass.; Portland and Rockland, Maine; and Astoria, Ore. LEADING SPECIES: Tuna led the food fishes in pounds landed with 295.6 mil- lion pounds. Salmon was next with 257.2 million pounds, followed by shrimp with June 1958 COMMERCIAL FISHERIES REVIEW 47 204.4 million pounds. The Maine herring catch was 153.6 million pounds, most of which was canned for human consumption, Haddock and ocean perch landings were almost identical, each being more than 133.0 million pounds. The whiting catch was 132.8 million pounds. The menhaden harvest was 1.7 billion pounds, accounting for 35 percent of the total catch. The ex-vessel value of several of the food fish was higher in 1957 despite the fact that some of the catches were smaller than in the previous year. The shrimp harvest was down 20 million pounds, but the ex-vessel value was $74 million, or $3 million above 1956. Thevalue of the salmon catch was $39,300,000. The value of the tuna catch (down 33 million pounds) was $38.4 million, or $5 million below 1956. The value of menhaden taken in 1957 was $22.1 million, or $6 million below 1956. CANNING: The quantity of fish canned for human food in 1957 was 644.7 mil- lion pounds as compared with 657.6 million povnds in 1956. There were 342.3 mil- lion pounds of pet food (with fish as an ingredient) and bait canned in 1957 as com- pared with 321.8 million pounds in 1956. The value of the 1957 pack of all canned fishery products was $334.8 million; that of the 1956 pack was $349.5 million. There was a $15-million drop in food canned for human use and a slight rise in the value of fish canned for pets. Tuna led the field in number of pounds canned with a record 232.5 million; salm- on was next with 152.9 million; mackerel was third with 59.7 million; Maine sar- dines were next with 46.0 million pounds; and then clam chowder with 36.6 million pounds. There were 342.3 million pounds of pet food processed. The 1957 packs of tuna, Maine sardines, mackerel, and pet food were higher than those of 1956; the packs of salmon and clam chowder were lower. UTILIZATION: Thirty percent of the commercial fisheries landings, or 1.4 bil- lion pounds, went into the channels of trade as fresh or frozen fish; 24 percent was canned; and 2 percent was cured. A total of 2.1 billion pounds, or 44 percent of the landings, was used for byproducts (oil, meal, and solubles) and as pet or animal food and bait. AREA DISTRIBUTION: Fifty-four percent of the 1957 production (2.6 billion pounds) was taken by Atlantic Coast fishermen. Fishermen from the Gulf States and the Pacific Coast each took 17 percent of the total; Alaskans caught 8 percent; and the fishermen operating in the Great Lakes and the Mississippi River system caught 4 percent. Most of the fishing was done in waters off the shores of the U- nited States and Alaska but nearly 0.5 billion pounds, or about 10 percent of the catch was taken on the high seas off foreign shores. More than half of this catch off foreign shores was tuna. STATISTICAL PUBLICATIONS: The 1957 review (Fisheries of the United States and Alaska, 1957--A Preliminary Review), Fishery Leaflet 393, differs from pre- vious ones in that it contains more complete and current domestic data and is a- vailable to the public and to the industry some weeks earlier than usual. In addition to data on production, processing, prices, and supplies of the domestic catch, there is considerable information on the fishery imports and exports and on world fish- eries.

These decreases more than offset higher imports of canned tuna. Imports of edible fishery products in February this year were up from the same month in 1957 for groundfish fillets, shrimp, and canned sardines and tuna. These increases in February 1958 were partially offset by decreases in the imports of lobster and spiny lobster tails, frozen tuna, and canned bonito. United States exports of processed fish and shellfish in February 1958 were higher by 8.3 percent in quantity and 33.3 percent in value as compared with Jan- uary 1958. Compared with the same month in 1957, the exports in February 1958 were down by 66.8 percent in quantity and 52.9 percent in value. The sharp de- creases in both quantity and value this February as compared the same month in 1957 were due, primarily, to a shortage of the usual exportable types of canned fish. KK kk GROUNDFISH FILLET IMPORTS, MARCH 1958: Imports of groundfish (includ - ing ocean perch) fillets and blocks totaled 10.2 million pounds in March 1958. Com- pared with the same month in 1957, this was an increase of 1.0 million pounds (11 percent). Increases of 1.1 million pounds of groundfish and ocean perch fillets from Denmark and 1.3 million pounds from Canada accounted for the over-all in- crease. Canada continued to lead all other countries exporting groundfish and ocean perch fillets to the United States with 7.6 million pounds during March 1958. 50 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Denmark was next with 1.5 million pounds. Imports from Iceland, the United King- dom, the Netherlands, West Germany, Japan, Miquelon and St. Pierre, and the Un-- ion of South Africa accounted for the remaining 1.1 million pounds. Imports of groundfish and ocean perch fillets and blocks into the United States during the first three months of 1958 totaled 31.9 million pounds, a decline of 3.4 million pounds (10 percent) as compared with the same period in 1954. Canada ac- counted for 72 percent of the January-March imports, followed by Iceland with 17 per- cent, and Denmark 7 percent.

Prior to the last week in April the Laboratory received re- ports of dead anchovies in large numbers at Virginia Beach, and dead striped bass or rockfish in the Piankatank River. Fish kills are not always caused by pollution or other human activities, the biologists report, for most deaths are caused by natural forces, disease, storms, and the like. Every year, in spring, just as the water begins to warm, dead and dying an- chovies are often seen along the beaches inside and outside Chesapeake Bay. In 1957 the kill was unusually large, and included young croaker, spot, menhaden, and other species. There are at least two possible causes of such kills, a disease that reaches its peak in April, or physical damage by winds and moving sand in shallow water. Winter diseases are known to kill other animals in Chesapeake Bay. Each year in early spring an increase in oyster mortality usually is observed. The oys- ter biologist at the Laboratory has made careful observations of the phenomenon, and almost every spring received complaints from oystermen that their oysters are dying. Preliminary studies suggest that this is caused by a microscopic ani- mal that enters oysters in winter and thrives in cold weather. Recent observations at the Virginia Fisheries Laboratory also have shown that oyster drills or screwborers begin dying in April. Striped bass often contract diseases that are associated with dietary deficien- cies. These sometimes cause an eye condition similar to cataracts in humans. Lack of adequate food in winter probably deprives the fish of vitamins they require for good health, and by the end of winter some are so weak they succumb. Anchovies and other fishes remain in deep water in the Bay or migrate south in winter. In spring, as the water warms, they move in close to the beaches, where more food is available. If a storm catches them in these shallow waters, they may be killed by suspended sand, which can remove their protective coating of slime and can damage their gills. Later, as the water becomes warmer, and more food has appeared farther offshore, they move out into areas where storm damage is less of a threat. Determining cause of death in marine animals is difficult, because very little is known about fish diseases and symptoms. Biologists at the Laboratory urge fishermen and Chesapeake Bay tidewater residents to report all kills they observe, giving if possible the kinds and numbers of animals seen, the extent and location of the area affected, and any other pertinent details. Such information is useful to biologists in diagnosing causes of death 52 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 Wholesale Prices, April 1958 The edible fish and shellfish (fresh, frozen, and canned) wholesale price index (122.4 of the 1947-49 average) de- clined 1.9 percent from the preceding month, but was higher by 2.5 percent as compared with April 1957. The decline is a seasonal one that usually occurs in the spring because landings of fish increase with good weather and improved fishing conditions. Wholesale prices for the drawn, dressed, and whole fin- fish subgroup from March to April 1958 declined about 2.2 percent due to lower prices for the fresh-water varieties and fresh drawn haddock at Boston. A decrease in the wholesale prices of these products is normal for this period of the year because the Great Lakes production im- proves and haddock catches reach a peak level in April. Increases of 5 to 6 percent in frozen dressed halibut and salmon wholesale prices failed to offset the price declines for the remaining products in this subgroup. Wholesale prices for drawn, dressed, and whole finfish in April this year were 3.0 percent higher than in the same month of 1957 because higher wholesale prices for frozen dressed halibut and salmon offset lower prices for fresh haddock fillets and fresh-water fish. : During April 1958 the fresh processed fish and shellfish FRESH EAST COAST SHRIMP ON DISPLAY AT ONE OF THE, subgroup wholesale prices declined 1.8 percent from the STANDS IN THE NEW YORK CITY FULTON FISH MARKET. preceding month due to lower fresh haddock fillet and Table 1 - Wholesale Average Prices and Indexes for Edible Fish and Shellfish, April 1958 With Comparisons Point of Avg.

Compared with April a year ago, the April 1958 index for this subgroup was down by 1.1 percent be- cause lower prices this April for fresh haddock fillets (down 11.3 percent) and shucked oysters (down 2.2 percent) were only partially offset by a 3.3-percent increase in fresh shrimp wholesale prices at New York. Frozen processed fish and shellfish prices were down by 6.0 percent in April 1958 as compared with the preceding month. Lower prices for frozen fillets of haddock (down 12.5 percent), ocean perch (down 2.5 percent), and shrimp (down 5.9 percent) accounted for the drop in the index between the two months, From April a year ago to April this year the frozen processed fish and shellfish subgroup index rose 1.1 percent due to higher wholesale prices for haddock (up 18.7 percent) and ocean perch (up 3.5 percent) fillets.

Prices of both canned tuna (up 1.3 percent) and Maine sardines (up 7.4 percent) were firmer this April as compared with the preceding month. Wholesale canned fish prices in April 1958 in- creased by 1.9 percent over the same month a year ago due to a 4.0 percent rise in canned tuna prices and an 8.4- percent increase in California sardine prices.

He also said that the fishing boat of 1957 will possess many features which today are still in the idea stage. The FAO Naval architect is secretary of the Second World Fishing Boat Con- gress, which is scheduled to be held in Rome in April 1959. He is arranging for the scientific papers on investigations and research which will be presented at the Con- gress. It is expected that naval architects, boatbuilders and designers, marine en- gineers, boat owners, skippers and fishermen, as well as government representa- tives from all the leading fishing countries will attend. "Developments in fisheries are rapid these days,'' the Naval architect said. "When we had held our First International Fishing Boat Congress in 1953, we had a paper on gas turbines for fishing boats and several papers about factoryship de- sign. Many participants thought we were too far ahead of practical possibilities, but today there are gas-turbine trawlers and dozens of huge factoryships operating, some in waters not before known to the fishing industry. "Today, all kinds of interesting possibilities come to mind. There are advances in stern trawling, the use of stabilizers, and progress in automation. Why, it may not be many years before big factoryships can be sent to sea with a skeleton crew and have the main working crew join them by supersonic airplanes when needed. "T venture to predict,'' he said, ''that atomic-powered fishing vessels will be sailing the seas before many years have passed." The 1953 Congress concentrated on design and construction. According to FAO, next year's Congress will take performance for its theme, and sessions will deal with fishing tactics, construction of vessels, sea behavior of boats, and productivity of vessels. The aim will be to gather from papers and discussions much practical design data; cost particulars and operational experience which will provide designers with information for building more efficient fishing boats. GREAT LAKES FISHERY COMMISSION MEETING HELD IN WASHINGTON, D. C,: The Great Lakes Fishery Commis- sion, established by treaty between the United States and Canada, met in Washington, D. C., April 9-10, 1958. The principal function of the Commission is the eradication of the sea lamprey predator which has so effectively destroyed most of the valuable food fishes of the upper Great Lakes. Chairman of the Commission is L. P. Voigt, Conservation Director of the State of Wisconsin. Other United States members are Claude VerDuin, Mayor of Grand June 1958 COMMERCIAL FISHERIES REVIEW 55 Haven, Mich., and Donald L. McKernan, Director of the U. S. Bureau of Com- mercial Fisheries. The Canadian Commissioners are: A. L. Pritchard, Director of the Conserva- tion and Development Service of the Department of Fisheries, Ottawa; A. O. Black- hurst, Manager of the Ontario Council of Commercial Fish- eries, Port Dover, Ontario; and W. J. K.

State conservation agencies were represented by Dr. Albert Hazzard of Penn- sylvania, Dr. Mason Lawrence of New York, and Lee Roach of Ohio. The principal method used to control the lamprey is the blocking of streams tributary to the Lakes. The lampreys are killed by electrical weirs on their up- stream migration to spawning grounds. Another method has been the subject of ex- perimentation, and very hopeful results are being obtained. This is the introduction into the streams of selective toxicants which kill the lampreys and their larvae but do not harm fish or leave a poisonous residue dangerous to human or animal life. Perfecting of this system will speed the work of lamprey control and bring nearer the time of rehabilitation of the lake trout and other commercial and sports fish- eries. INTERNATIONAL PACIFIC HALIBUT COMMISSION CANADA APPROVES REVISED REGULATIONS: The Canadian Department of External Affairs has informed the U. S. Department of State that the Canadian Goy- ernment in Order in Council No. P.

JAPAN-RUSSIA FISHERIES NEGOTIATIONS FOR 1958 JAPAN AND RUSSIA SIGN AGREEMENT ON SALMON QUOTA: The Japan- on April 22, 1958, after more than three months of negotiations. The following are the salient features of the agreement: (1) the total salmon quota will be 110,000 metric tons; (2) Japan will be permitted to operate one fishing fleet in the Okhotsk 56 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 | | Sea with a total catch limit of 6,500 metric tons which will form part of the 110,000 quota; and (3) Japan and the U. S. S. R. have agreed to refrain from engaging inhigh- seas salmon fishing in the Okhotsk Sea beginning on January 1, 1959. The press has reported that the two countries have agreed to conduct a joint conservation survey in the Okhotsk Sea during 1958. Even if undertaken, the survey will not provide Ja- pan with the right to fish for salmon in the Okhotsk Sea in the immediate future. The press has been generally critical of the fact that Japan agreed to halt salm- on fishing in the Okhotsk Sea stating in effect that Japan by this action gave up the principle of freedom of the seas. The Japanese Prime Minister vehemently denied this charge in Diet questioning on this subject. The view was expressed by thepress that Japan should have accepted the 100,000-metric ton quota and left future fishing operations in the Okhotsk Sea to the results of the 1958 joint conservation survey. The Government of Japan, as reflected in statements made by the Agriculture-For- estry Ministry, considers the 1958 agreement to be considerably better than could have been anticipated at the outset of the negotiations, recalling that the initial Sovi- et proposal was to limit the Japanese salmon quota to 80,000 metric tons. The Gov- ernment also considers the agreement favorable in view of the fact that it was not tied to the question of the Peace Treaty, although the safe fishing problem still re- mains unsolved. Japanese fishing industry representatives have indicated that they are reasonably satisfied with the new quota even though they, of course, would have liked to have obtained a quota closer to the 145,000 metric tons initially requested by Japan in the negotiations.

The 1957 amendment to the regulations providing special rules for the use of cover for the protection of the cod end is being considered by the Governments concern- ed. The Governments of France and Norway have inform- ed the Depositary Government of their acceptance of the amendments. In March-April 1957 a French expert visited Canada and the United States and participated in cruises with commercial fishing and research vessels for studying fishing methods, especially the means in use of protect- ing the trawl during hauling. June 1958 COMMERCIAL FISHERIES REVIEW 57 WHALING ANTARCTIC WHALE-OIL OUTPUT DOWN SLIGHTLY BUT SPERM-OIL OUT- PUT UP: Whale-oil production in the Antarctic during the 1957/58 pelagic whaling season declined slightly from a year earlier, according to preliminary data released by the International Whaling Commission, Sandefjord, Norway. Antarctic sperm-oil production, however, was one-fifth greater than the year before. The Antarctic sea- son, ended at midnight March 16, 1958, and lasted 69 days, as did the season of a year ago.

The major Antarctic producer, Norway--with 9 floating factories--had a de- cline of almost one-sixth in whale-oil production, but output of sperm oil was one- fifth above that of 1956/57. Japan, operating 6 floating factories (in 1957/58 it ac- quired the/former Abraham Larsen, which operated under the flag of the Union of South Africa in 1956/57), sharply increased both its whale-oil and sperm-oil produc- tion. The United Kingdom, with 3 floating factories, had a slight decline in whale-oil outturn and an increase in sperm-oil output. Although the U.S. 5S. R. had only one floating factory in 1957/58, 6 catcher boats were added, to bring the total to 24 catch- ers--almost twice the number used by any other floating factory. Thus, the Soviet Union's whale-oil production was up sharply from last year. The Netherlands! sin- gle floating factory increased its whale-oil output 15 percent from last season, and its sperm-oil production was almost double that of 1956/57. iy Ys Se Aden COMMERCIAL FISHERIES IN EASTERN ADEN PROTECTORATE STUDIED: A British fisheries Officer was assigned to the Eastern Aden Protec- torate in July 1956, for the purpose of developing the fisheries along the 450-mile coastline which extends from the Western Aden Protectorate to the Sultanate of Muscat and Oman. After operating for a year and a half on a very limited budget (the original four-year project had been allocated £28,000 (US$78,873) from the British Colonial De- velopment and Welfare Fund), in 1957 the Fisher- ies Officer received from the Ruler of the Qa'iti Sultanate, the most important state in the Eastern Aden Protectorate, a contribution of £18,000 (US$50,704) for the project. This sum of money enabled the Fisheries Of- ficer to alter the ex-Scottish herring drifter with which he was provided, so as to make the boat more suitable for fishing in Aden waters. He has patterned the boat as much as possible along the lines of a purse seiner used in the United States. With this arrangement, and with some new nylon and kuralon nets from Japan (three floating gill nets of 4-inch mesh tied together), the Fisheries Officer recently made his first large catch--ahaul of 5 tons of sardines (Sardinella longiceps). His technique was to Set the gill net in a large semi- circle around the school, and then run the boat across the mouth of the loop. Having caught al- most the entire school, he let the net down for > 58 hour and was astonished to find that in this short time two smaller schools of sardines had entered the net as well. When the net was hauled aboard nearly every mesh was filled (figs. 1 and 2). Though this was his first commercially-profit- able catch, the Fisheries Officer made other catches FIG. 1 - A LARGE HAUL OF SARDINES IN A GILL NET BEING HAULED ABOARD THE VESSEL USED BY A BRITISH FISHERIES OFFICER IN EXPLORING THE FISHERIES OF THE EASTERN ADEN PROTECTORATE. along the coast with various nets inherited from the Aden Colony Fisheries Department. His cot- ton kingfish net catches consisted primarily of small shark, which brings a very high price for drying in Aden. It was found that the trammel net brought up an assortment of sea life that consider-, ably shortened the life of the net: sea-turtles, man- ta rays, crabs, crayfish, a mass of Murex shells, as well as small sharks, sole, rock cod, and other bottom feeders. For commercial purposes, however, the Fish- eries Officer intends to concentrate on surface net- ting, states an April 5, 1958 dispatch from the U- nited States Consulate in Aden. There is little doubt in his mind that the surface fishing in south- ern Arabian waters is among the richest to be found anywhere in the world. In attempting to es- tablish commercial fisheries which can be handed over to local management, the Fisheries Officer plans to exploit inshore surface fishing first, being confident that new grounds will not have to be sought for many years. This type of fishing is, moreover, more suitable to the type of native fishing craft be- ing used along this coast. A ready market exists for dried sardines in the hinterland of the Protectorate coast, bothas a feed for livestock and as fertilizer for tobacco crops. The present system of preserving the fish, the simple and inexpensive method of letting them dry COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 in the sun and lacing them with salt, would be quite - adequate for even the exportation of large fish, providing the fishermen could be persuaded to use clean salt and to gut their fish thoroughly. Train- ing the fishermen in modern methods is, of course, at least one half of the Fisheries Officer's job. He finds that there are considerable obstacles to in- troducing new practices and equipment. In many localities the fishermen are the most conservative element in society and observe a ritual of arbitrary restrictions on their trade which have deep roots in religion and superstition. In some towns there are rules prohibiting the use of nets, or, variously, of different baits--live bait or dead bait, lures, or crabs. Sometimes night fishingis prohibited. These "rules of the sea'' are legislated and enforced by the headmen of the fishing community in each town. Violators are tried by the headmen themselves in their own fisheries courts, and their rule is final. FIG. 2 - A BOATLOAD OF SARDINES CAUGHT WITH GILL NETS. Some areas have proved to be more conserva- tive than others; it is often the smaller towns and villages, especially those that depend for their main livelihood on fishing, that have the greatest urge to improve their techniques and equipment. Qusa'ir, a small town near the Mahra Coast, is an example of the progressive and adventurous spirit that one occasionally finds. Each year the Qusa'- iris send a fleet of shark fishing ''sambuks'' as far afield as Socotra, and they are the only ship build- ers along the coast--save the Adenis themselves-- who build boats with bolted instead of sewn seams. Towns such as Qusa'ir are naturally only too happy to substitute nylon for cotton nets; in some cases cotton itself replaced cheap Indian jute fibres as recent as 20 years ago. It is a fairly accurate generalization to say that while the bigger towns are conservative in temper, the smaller ones wish to go ahead. Unfortunately it is the first who have the money to change over, and the second who do not. The Fisheries Officer's successes in the smaller towns can never pay off until (and this is his plan) he has organized a viable industry in a large town where the big merchants will have an interest in the venture. Once estab- lished as a profitable enterprise, modern commer- cial fishing would probably expand as merchants go to other points along the coast to set up rival ven- tures. Only by the artificial system of extending substantial loans to individual indigent fishermen could modern gear be introduced initially in the small fishing towns. x June 1958 COMMERCIAL FISHERIES REVIEW 59 Brazil FROZEN TUNA MARKETED BY JAPANESE-SPONSORED FIRM: The Price and Supply Commission of the State of Pernambuco, Brazil, announced that 640 met- ric tons of fish were made available to Recife and other parts of Pernambuco dur- ing Holy Week (March 30-April 15), according to a dispatch from the U. S. consulate at Recife, dated April 7, 1958. A Japanese-sponsored Brazilian firm supplied 560 tons of frozen albacore tuna, which was sold at the standard retail price of Cr$30 per kilo (about14 U. S. cents per pound). The traditional native ''jangada'' fleet sup- plied 80 tons of fish to Recife at retail prices ranging from Cr$70 per kilo (about 33 U. S. cents per pound) for dressed high-quality fish to Cr$30 per kilo (about 14 U.S. cents per pound) for round inferior-quality fish. The Brazilian-Japanese firm sells frozen tuna to wholesalers at Cr$23 per kilo (about 11 U. S. cents per pound). The firm supplied tuna to other coastal cities of Brazil as follows: Rio de Janeiro, 60 tons; Salvador, 200 tons; Maceio, 50 tons; Natal, 50 tons; Joao Pesso, 30 tons; and Fortaleza, 140 tons. It is reported that profits have been large enough to stimulate the interest of other private firms to establish modern fishing fleets of their own. It is believed that the ''jangada" fish- ermen, which may be forced out of business as a result of their relatively small catches and the price competition, will be trained to work as crews of modern fish- ing vessels. In all probability, Brazil's booming tuna industry should provide high food value protein to the low-income groups of the Northeast at reasonable prices. If expan- sion in the industry continues, Brazil may export tuna in quantity within a few years. NOTE: BRAZILIAN CRUZEIROS CONVERTED AT RATE OF CR$97.50 EQUAL US$1, * KOK KK Cr$30 per kilo (about 14 U. S. cents a pound) after considerable discussion. Repre- sentatives on the Commission from local industrial unions and the army wanted the price set at Cr$23 (about 11 U. S. cents a pound). It is estimated that the Japanese- sponsored fishing firm could make a profit at Cr$23 per kilo if they were guaranteed a market for capacity production. The native Brazilian fishermen are reported to charge Cr$60-80 per kilo (28 to 37 U. S. cents a pound) for their catches, These fishermen would be hard hit in trying to compete with the Japanese-sponsored firm except for the fact that the con- sumer looks on albacore as a ''poor man's'' food. The Japanese firm at present has caught and marketed tuna only, but may later attempt to market whale meat. A small whaling firm at Joao Pesson, Paraiba, has been purchased by the Japanese- sponsored firm, the United States Consulate at Pernambuco reports in March. NOTE: CRUZEIROS CONVERTED AT RATE OF CR$97.50 EQUAL US$1. Canada ATLANTIC SALMON MEETING: Specific recommendations for the improve- ment of Canada's Atlantic salmon stocks in the Maritime Provinces, Quebec, and Newfoundland were made at the annual meeting of the Federal-Provincial Co-ordi- nating Committee on Atlantic Salmon, held in Ottawa, February 11-12, 1958. The suggestions made dealt with regulations as to netting, open seasons, con- trol of poaching in certain areas, the stocking of streams from salmon hatcheries, 60 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 and mitigation of the damage done to salmon populations by the spraying of forests with DDT in efforts to wipe out the spruce budworm. In this connection, the Co-or- dinating Committee reported that a search was being made for an insecticide other than DDT which would not harm fish. CRERTIG U : Problems involved in efforts not only to halt the decline but to increase the Atlantic salmon popu- lations were particularly complex because of the marked susceptibility of this species to even the slightest changes in its fresh-water environ- ment, the Canadian Minister of Fish- eries said. Frequently these changes were so subtle as not to be noticeable to the untrained eye but the effects were nevertheless drastic. The Minister cited the case of several European countries which had at one time enjoyed large populations of salmon but had seen them become seriously de- pleted. Much of this depletion was attributable to the impact of spreading civiliza- tion on the inland waterways in which the salmon are hatched and nurtured in the years until they go to sea. (Canadian Trade News, February 1958.) ok kk Ok 1956: During 1956, the per capita consumption of fishery products in Canada amounted . .

The part of the Directive from the Canadian Director of Inspection and Con- sumer Service states: "7, Containers of shucked shellfish meats must be labeled in terms of net weight, as required by section 9 of the Fish Inspection Act.

HOOK OK OK OAK FUR-SEAL INVESTIGATION IN NORTH PACIFIC: The first Canadian group to begin research work on North Pacific fur seals left Nanaimo, British Columbia, on February 13 for a three-week cruise of waters offshore from Barkley Sound. This cruise initiated a program which calls for a Canadian catch quota of from 500 to 750 fur seals for scientific studies during 1958. June 1958 COMMERCIAL FISHERIES REVIEW 61 The quota was set by the new North Pacific Fur Seal Commission, which ismade up of representatives of the United States, Canada, the U. 5. 5. R., and Japan, and which held its first annual meeting in Washington in January 1958. The North Pacific Fur Seal Convention prohibits pelagic sealing and also pro- vides for scientific investigation of the migratory movements of the seal herds, their wintering areas, and feeding habits. The commercial catch of fur seals is made each breeding season on the Pribilof Islands in the Bering Sea, and is strictly controlled. The Pribilofs are in United States ter- ritory. Smaller catches are made on the Commander and Robben Is- lands on the Asiatic side of the North Pacific. The Canadian research group is made up of members of the staff of the Fisheries Research Board of Canada from the Board's Biological Station at Nanaimo. They will take their limited catch on the surface of the ocean, a form of sealing prohibited to any but authorized scientific investigators and Indians, Aleuts, Eskimos, and Ainos. The animals taken will be skinned and the contents of their stomachs examined. Pelts will be shipped to a fur-manufacturing firm for process- ing. FUR SEAL SWIMMING. British Columbia fishermen, operating in coastal waters, have occasionally shot young fur seals under the impression that the animals were hair seals, thus risking heavy penalties. The method of distinguishing between the two species is by observ- ing their manner of swimming. Hair seals swim only with the top of the head showing above water. Fur seals are in the habit of raising head and shoulders vertically out of the water and will frequently swim on their backs with flippers showing. (Canadi- an Trade News, February 1958.) sk oe KOK NEW TYPE HEADLINE ROPE DEVELOPED FOR MID- WATER TRAWLS: The headline ropes used in midwater trawl nets should be strong, light, relatively thin, and flexible. In these nets the headline completely encircles the mouth opening, whereas in bottom trawls the headline is referred to as the top rope to which the floats are attached. These ropes should be so constructed that they will not shrink or retain permanent twists after repeated immersion in water. To meet these requirements the Canadian Nanaimo Biological Station in British Colombia developed a headline which was constructed from pre- formed alternate-lay galvanized wire rope, sheathed with braided spun nylon rope. In the first midwater trawls developed at the Biologi- cal Station the headlines were constructed from manila- clad wire rope (beiflex cable) to withstand the heavy strains imposed while towing. This type of headline rope was not extremely satisfactory because after immersion in the water only a few times, it twisted and pulled the netting in the wings and body out of shape. Most of the twisting was eliminated by use in the headline of shorter lengths of beiflex cable joined together by galvanized thimbles to a metal ring, at the points where the base of the wing corners were attached to the body. However, the alternate stretching and shrinking of the rope and the gradual weakening of the wire cores caused by the corro- sive action of the salt water could not be overcome. mK OK OS The new type of nylon-sheathed headline was con- structed of 1-inch diameter 6x9 (12-6-1) galvanized preformed alternate right and left lay wire rope clad with a braided spun nylon sheath. Braided spun nylon was chosen for the sheathing to eliminate slippage of the knots in hanging the netting to the headline. The sheathing was marked with a continuous red line to assist in preventing twists and turns being placed in the rope when hanging the netting to the headline. Although the cost of the new experimental headline was about three times that of the combination manila- clad wire rope, production on a commercial scale would undoubtedly reduce the price to an amount comparable with that for other ropes. This headline construction proved to be very satisfactory in the midwater trawl and ocean perch nets tested during experimental op- erations during the summer of 1957. The headlines re- mained flexible and no twists, kinks, or signs of shrink- age were observed in the ropes during the three months of experimental fishing. This rope was as easy to handle as other types of headline ropes. The rope could be spliced readily by paring the nylon sheathing away from the steel cable at the required place and afterwards covering the area again with a synthetic tape. The in- crease in the breaking strength and longer life of the new rope were important factors which would warrant its use in trawl nets. %* OK OK OK 62 COMMERCIAL FISHERIES REVIEW OCEAN PERCH DEEP-WATER EXPLORATIONS IN WEST ATLANTIC NORTH OF FLEMISH CAP: Exploratory fishing for ocean perch in the western Atlantic Ocean area north of Flemish Cap (a small fishing bank about 250-300 miles east of Newfoundland) by Canadian scientists of the Fisheries Research Board’s Biological Station inSt. John’s, Newfoundland, was carried out by the station’s M/V Inves- tigator II. Depths between 100 and 396 fathoms were explored. Ocean perch were absent in the trawl sets at 100to108 and 386 to 396 fathoms and scarce at 150 and 350 fathoms. They were most abundant at 250 fathoms where each of three sets produced a good catch. At depths of both 200 and 300 fathoms 1 set out of 3 gave good results. In view of the small size of the net (a No. 3 - 35 otter trawl with a 39-foot headrope and a 50-foot footrope), the short towing period of only ahalf hourper set, and the prob- able inefficiency of single-wire fishing, the catches at 250 fathoms were suitable for commercial exploitation. As regards size, the proportion of small (less than 10 inches long) ocean perch present decreased from the sk ok a OK REFRIGERATED SEA WATER USE TESTED IN NORTH PACIFIC HALIBUT FISHERY: The use of refrigerated sea water to preserve halibut in the North Pacific Ocean fishery has been investigated by the Fisheries Research Board of Canada. Refrigerated sea water fish holding proved suc- cessful in the Board’s earlier experiments on a salmon packer, and it was decided to apply a test tohalibut fishing since the long holding time, required because of the length of a trip, dictated some improvement in holding methods. A halibut trip may consist of 12 days average fishing time plus 1 to 5 days returning to port, plus 1 to 5 days in port prior to unloading. The vessel selected for the experiment was the Silver Viking, which was being built for private ownership, thus making possible the incorporation of the system into her original construction. Since this vessel was designed as a combination salmon seiner and halibut long-liner, it also made possible a study of the application of refrigerated sea-water holding to salmon seining. The vessel is a typi- cal Pacific salmon seiner of wood construction, 78 feet long with a 22-foot beam. Six tanks were installed in her hold, three on either side of the shaft. The tanks were constructed of 3/16-inch steel plate and surfaces unsup- ported by the hold lining were stiffened by 2-1/2-inch angle irons toe-welded at two-foot centers. The inside surfaces were coated with an Epoxy resin coating to resist erosion. Two inches of cork insulation were applied to the external surfaces. Cooling coils, located in each tank, were made up of 250 feet of 3/4-inch O.D. steel tubing, the assembled coil being hot-dip galvanized. The coils were contained in closed compartments along the inboard tank sides. Circulation of the chilled sea water was provided through this compart- ment by a separate circulating pump for each tank. Refri- geration to these coils was supplied by two compressors (one for the three port tanks and one for the three star- board tanks). To augment this refrigeration system there was a com- pletely separate one comprising a shell and tube chiller, circulating pump, and refrigerant compressor. This sys- tem was used to speed up the initial cooling of any one tank but also served as a standby system in event of failure of the tank coil system. All pumps and compressors were electrically driven. Power was supplied by two Diesel-driven alternating-cur- rent generators. These generators were of the 120- to 208-volt type which supplied either single phase 120-volt current for the small motors and ship lighting or 208-volt three-phase power for the larger motors. The Silver Viking engaged in salmon seining in July and August of 1956. Round sockeye and chum salmon were brought to port in excellent condition after the week’s fish- ing, and sockeye, after further sea-water storage to a total holding time of 14 days, was still judged to be excel- Vol. 20, No. 6 shallowest tothe greatest depths. Below150 fathoms, apart from asmall decrease at 250 fathoms, ogeanperch average sizes increased with increasing depth. Neglecting the very small proportion of the fish less than 10 inches long, the catches were indicative of excellent suit- ability inthe 200- to 300- fathom range where, considering the very smallnet used, there shouldbe large oceanperch catches ranging upwardto 10,000 pounds or more per hour’s tow for the larger commercial draggers. The bottom in the area north of Flemish Cap deepens gently andgradually and is smooth. There were no serious injuries to the netin 20 drags, although compared with the nets of large trawlers, the net of the Investigator II was a rather delicate one of cotton with a light manila cod end and with rubber rollers only six inches in diameter. Trawlers fishing for ocean perchin this area must be preparedto drag as deeply as 200 to 250 fathoms and have winches operating at a fast enough speed to make deep- water fishing profitable. (Canadian Trade News, January 1958.) HK OK OK lent. Some difficulty was encountered with the loss of scales and skin pigment of round coho and jack king salm- on. The dressing of all fish of these species overcame this trouble whereas the dressing of sample individuals did not. These observations gave support to a theory that the damage was caused by a destructive enzyme disgorged with the stomach contents of these actively-feeding fish. Belief that this loss of scale and skin pigments was caused by the motion of fish in the tanks seems unlikely since this did not occur in loads composed entirely of nonfeeding fish or dressed fish. The use of this equipment in salmon seining showed many advantages which may in the future be of value. First was the ship’s ability to operate in areas remote from canneries or packers. Second was that no time was lost in the daily delivery of fish. Third was the much in- creased value of some types of fish when delivered by the fishing vessel itself directly to the port. This was em- phasized by a week’s catch of chum salmon which was de- livered to the fresh fish market. The tank trunks on deck hindered the crew during salmon-seining operations while handling the net and brailing fish aboard. However, simple alterations were made which eliminated this difficulty. The vessel engaged in halibut fishing in the December 1957 opening of halibut in Area 2. Some 36,000 pounds were caught and sold 8 to 15 days after catching. These fish were in fine marketable condition, and samples held in a tank at the Vancouver Technological Station to a total time of 29 days were still in good condition. Many advan- tages were demonstrated by this trip. Foremost was that halibut could be held beyond any period practical in fish- ing. Elimination of icing of fish increased the effective- ness of the crew, which would mean larger catches in periods of good fishing. The equipment in no way appeared to hinder the handling of gear or fish. Of special interest to this project was the chiller which, as explained previously, was designed to assist in the ini- tial cooling of the sea water and to a limited extent to act as an emergency system. However, since the first purpose was of great importance, the chiller was designed with a close tube spacing permitting high water velocity and hence a high heat transfer from the tubes. Thus a chiller of small outside dimensions which could be easily installed or dismantled for maintenance could be made. It was ex- pected that this design would not permit attaining low tem- peratures, because of ice formation on the tubes. This, however, was not the case as it has been proven possible to cool water to 30° F. with the chiller. The chiller had an outer shell of six-inch Kralastic pipe. The use of this material served three purposes: it reduced the weight of the chiller, eliminated corrosion of the shell, and provided sufficient elasticity to prevent rupture by freeze-up. The shell contained 240 feet of 5/8-inch O.D. copper refrigerant tubing arranged for dry refrigerant June 1958 COMMERCIAL FISHERIES REVIEW 63 expansion in six parallel circuits of four horizontal runs obtained with two compressors and two chillers as would of tubing extending the length of the shell.

The new research was announced by the Canadian Fisheries Minister and was started early in March 1958. The project, sponsored by Canada's Department of Fisheries through its Indus- trial Development Service, brings together in a concentrated 30-day program per- sonnel of the Fisheries Research Board of Canada, the National Research Council, the Royal Canadian Navy, and the Department. With the aid of professional divers, a diving chamber, underwater television, and movie cameras, the scientists, in conjunction with nontechnical members of the team, will invade the bottom-of-the-sea haunts of lobsters in the waters off Yar- mouth, Nova Scotia. The objective of the research, among other things, is to determine whether metal lobster traps are more economically practical than wooden traps in the catch- ing of lobsters. Last year fishermen in the Maritimes, Quebec, and Newfoundland landed about 44 million pounds of lobsters which had a value to the fishermen of over US$14 million. This phase gives observers a ringside seat from which they can observe the be- havior of lobsters in their native habitat. Findings will not be reached for some time but they are expected to go a long way toward solving the problem of trap loss- es by storms. The HMCS Greenwood, of the Royal Canadian Navy, based at Halifax, will take part in the project. This vessel's diving chamber will be submerged on the lobster grounds and underwater movie and television cameras will record the actions of the lobsters. Other technical equipment will also be used to measure the effects of vi- brations, currents, etc. In addition to the Naval vessel, three boats of the Depart- ment of Fisheries will participate in the operation. They are the Limada, Modiolus I, and Serpurla. During the past four years metal traps have been tested on the various fishing grounds. The original project involved the use of steel traps fishing against wood- en traps. The continuing experiment will include not only the old-type steel traps with three fishing heads and the door opening on the top, but also new steel traps with three fishing heads, the trap opening from the bottom, and catch locks on the ends; aluminum traps with three fishing heads with catch locks hooking under the bottom; nylon rope and twine; aluminum floats; high purity zinc anodes to help curb erosion of the steel traps; aluminum and fibreglass lobster buoys. Experience gained in four years of testing under varied conditions in various parts of the Maritimes has proven that metal traps stand up better under gale and sea conditions than do traps made of wood. Metal traps also outlast wooden traps 64 COMMERCIAL FISHERIES REVIEW Vol. 20, No. 6 by many years. Metal-producing firms are cooperating by supplying some of the traps necessary for the experiments. Trap losses through storm have been one of the main problems lobster fisher- men have had to face. Although the Department of Fisheries had sponsored trap in- surance, only a portion of lobster fishermen have taken advantage of this protection. As a result, a severe storm can bring great economic hardship to noninsured fish- ermen. Coupled with information already tabulated showing the number of lobsters caught in both metal and wooden traps, the undersea observations should fill in the missing parts of the picture.

The Minister of Fisheries pointed out that fishermen producing these relatively low-priced products have been faced with controlled prices in many of the export markets and rising costs of production.

The assistance does not apply to products sold in the UnitedStates. (Canadian Trade News, February 1958.) * STUDIES ON HOLDING LOBSTERS IN ARTIFICIAL SEA WATER: Studies on how temperature and crowding affect the holding of lobsters in artificial sea water were con- ducted at the Fisheries Research Board of Canada’s Bio- logical Station at St. Andrews, New Brunswick. The discovery that lobsters can live in artificial sea water has aided in the recent growth of inland markets for live lobsters, Suitable artificial sea water is easily prepared by dissolving five readi!y-available salts in tap water. Many inland storage and display units that hold from 50 to 500 pounds of lobsters in artificial sea water are now in use and more are being built. Elaborate glass and stainless steel units with mechanical refrigeration, aeration, and filtration are manufactured. These are used primarily for display purposes, If suitable water conditions are maintained in these units, the lobsters will remain active and form an attrac- tive display for long periods, For practical reasons the volume of artificial sea water in inland holding units is limited and the lobsters are usually crowded. Under such conditions the waste products from the lobsters gradually accumulate and the water becomes murky and finally toxic. At this point the lobsters will weaken and die un- less the water is replaced. The accumulation of toxic materials can be slowed down considerably and the appear- ance of the unit improved by filtering out the solid waste products as they are formed. However, even with effi- cient filtration the water eventually becomes toxic. If the water is not changed often enough unnecessary losses will occur, On the other hand too frequent changes mean a waste of time and money. From general observations it was obvious that both the temperature of the water and the degree of crowding were important factors in determining how long the water would remain suitable. More precise information on the effects of these factors was obtained from the following experiments, Fifty lobsters (total weight 50 pounds) were held in 50 (imperial) gallons of artificial sea water at each of four temperatures until all died. The water was not changed or filtered during the course of the experiment but was well aerated tg provide an ample supply of dissolved oxygen. At 34° F. the lobsters lived an average of 26 days; mK OK at 43° F.,19 days; at 57° F., 10 days; and at 68° F., 6days. These results show clearly that the lower the temperature the longer the water will remain suitable. Twenty lobsters (20 pounds total weight) were held in five different amounts of artificial sea water ranging from 10 to 80 gallons. This provided five degrees of crowding as follows; 1/4, 1/2, 1, 1-1/2, and 2 pounds per gallon. The water temperature was maintained at 40 F. andthe lobsters: were held in the same unfiltered but well-aerated water until all died. At 1/4 lb. per gal. the lobsters lived an aver- age of 73 days; at 1/2 lb. per gal., 53 days; at 1 1b. per gal., 33 days; at 1-1/2 lbs. per gal., 22 days; and at 2 lbs. per gal., 16 days. It is clear that the water remains Suitable longer when the lobsters are less densely crowded--over four times as long at 1/4 lb. per gal. as at 2 lbs. per gal. At temperatures near the freezing point lobsters are Sluggish and unattractive for display, and refrigeration costs are higher. There is also the danger of killing lobsters at very low temperatures, especially during the summer when they have been accustomed to warm water. Lobsters can be held at moderately high temperatures but the water must be changed frequently. The best compro- mise for Tost holding purposes appears to be a tempera- ture of 40 to 45° F. Lobsters can be held at various degrees of crowding but the more they are crowded the more often the water must be changed. In general the less the crowding the easier it is to provide adequate aeration and filtration and the longer the water remains suitable. In deciding the crowding that is best for his particular purpose an oper- ator must consider the space required, the cost and appear- ance of his holding unit, and the inconvenience and loss of time involved in frequent water changes. In inland holding one of the operator’s primary concerns is knowing when to change the water to avoid unnecessary losses. Some lobsters are, of course, injured or weakened in shipment and will die shortly after they are placed ina holding unit. Such losses can to a large extent be avoided if each shipment is examined carefully and the weak lob- sters are processed quickly. From the daily records of deaths in the experiments reported here and other similar experiments, it is possible to estimate how long the water will remain suitable at various degrees of crowding. If vigorous lobsters are held at 40° F. in unfiltered artificial June 1958 sea water, there should be no Serious losses if the water is changed as follows: every 10 days when crowded to the extent of 2 lbs. per gal.; every 2 weeks at 1-1/2 lbs. per gal.; every 3 weeks at 1 lb. pergal.; every 5 weeks at 1/21b. COMMERCIAL FISHERIES REVIEW 65 per gal.; and every 6 weeks at 1/41b. per gal. Lobsters that have become weak because of toxic waste products normally revive quickly when the water is changed.

The decree states that re- newal of this two-year permit may not be granted; (2) To qualify for issuance of such a permit, foreign craft must be not more than five years old, if of wood, and nor more than ten years old, if of other material. Furthermore, evidence that the ves- sel is of high-grade quality and construction must also be provided.

KOK OK OK OK OWNERSHIP OF FEW SHARES OF MEAT PACKER STOCK MAKES MEAT PRODUCTS MARKETER A "PACKER:" Purchasing a few shares of stock of a recognized meat packer makes a mar- keter of meat, dairy, and poultry prod- ucts a ''packer,'' and thus prevents the Federal Trade Commission from proceed- ing against it on charges of violatinglaws administered by the Commission, hear- ing examiner of that agency ruled (Initial Decision 6459, Food Products) on April 25. The examiner held that a large Wash- ington, D.

Granting the super market chain's mo- tion to dismiss a Commission complaint charging it with inducing illegal pro- motional allowances, he said the Secre- tary of Agriculture has exclusive juris- diction over the chain's interstate com- mercial activities and the Commission has none. This is not a final decision of the Commission and may be appealed, stay- ed, or docketed for review. In a previous dismissal order, the examiner had ruled that the preparation of sausage and meat loaf makes the su- permarket chain a packer under the stat- ute. The Commission later reversed this decision, ruling that these meats are already meat products when received and supermarket chain's grinding and seasoning of them are customary mer- chandising operations which do not of themselves make the chain a packer. Another reason given in the reversal opinion was that there was no showing that the chain owns or controls any in- terest in a packing establishment. In the decision, the examiner said, "Respondent has now supplied that de- ficiency or taken that suggestion by pur- chasing, as of March 28, 1958, 100 shares of the common stock of a meat and poultry packing firm, and accord- ingly now claims coverage under clause (2) "(This provides that a marketer of these products is a packer if it owns or controls, directly or indirectly, through stock ownership or control or otherwise. . . any interest'' in a packer as defined elsewhere in the statute). The examiner emphasized this clause "does not read or hint 'substantial in- terest' nor is any quantum or percentage of interest or ownership mentioned." He then concluded: ''The contention that this ruling opens the door for all actual or alleged violators of the Feder- al Trade Commission Act who happen to market meats, meat food, dairy, and poultry products or eggs, to escape cor- rective action by the simple and relative- ly inexpensive purchase of a few shares of stock in a 'meat packer' overlooks the COMMERCIAL FISHERIES REVIEW 81 unambiguous statutory command, I can- not conscientiously twist or torture plain English to forestall that result. The rem- edy lies with those who wrote into law that plain English--the Congress of the United States," The amended complaint of May 7, 1957, charged the supermarket chain with inducing special allowances from suppliers for promotion of an anniver- sary sale which it ''knew or should have known" were not being offered to com- petitors. Department of the Interior BUREAU OF COMMERCIAL FISHERIES ASSUMES RESPONSIBILITY FOR GRADING SERVICE TO FISHING INDUSTRY: The U. S. Department of the Interior has assumed, under the authority of the Fish and Wildlife Act of 1956, the re- sponsibility for furnishing inspection and grading services to the fishing industry. The U. S. Department of Agriculture will continue to furnish such services until July 1, 1958, at which time the transfer of functions will be effected. Administrative authority has been delegated to the Bureau of Commercial Fisheries to supplement its standards development program, Bureau technol- ogists anticipate no significant changes in inspection service personnel or pro- cedures, The Federal shield and grade symbols, to all intents and purposes, will be identical with those now in use by processors. Contract renegotiation will consist of a simple change-order re- quiring only the signature of the proc- essor for consummation. The inspection and grading services for the fishing industry will be adminis- tered by experienced fisheries personnel. Continuous inspection and grading services for fish sticks, fish blocks, and breaded shrimp will be made available to processors who request the services. Continuous inspection services also will be available for all fishery products even 82 COMMERCIAL FISHERIES REVIEW though no grade standards have as yet been developed for such products. In addition, inspection services for specific lots of fishery products will be furnish- ed and may be requested. ee U. S.

Port au Port Bay, New- foundland; Northumberland Strait, Prince Edward Island; the Digby and Grand Manan areas of the Bay of Fundy; the bays of the Maine coast; Stallwagen Bank and Cape Cod Bay; the Hudson Canyon area; and the Virginia Capes, all sup- port small local fleets of sea scallopers. The total catch from all these areas, however, is small whencompared to the crop which the New Bedford boats har- vest from Georges Bank. About 60 percent of the total sea-scallop catch is landed at New Bedford and almost all of it comes from Georges Bank. Seascal- lops caught on Georges Bank are also landed at Gloucester, Mass.; Rockland, Me.; and Lunenburg, Nova Scotia. The greatest known sea scallop grounds are found between the 20- and the 50-fathom curves on Georges Bank. A dredge set almost anywhere in this area will bring up at least a fewsea scallops. Within this generalarea, the Northern Edge, the Northeast Peak, the Southwest Part, and the South Channel grounds have been, for the past 10 years, the most consistent producers of sea-scallop crops. Many areas that are known to have concentrations of large sea scallops are not usually fished because the rough bottom damages the gear excessively. --Fishery Leaflet 442, Sea Scallop Boats and Gear, August 1957.

Beverton and Sidney J. Holt, illus., printed, $22.68. British Information Services, 45 Rockefeller Plaza, New York 20, N. Y. The international regulation of fisheries in a region such as Europe, where there are more than a dozen sovereign states keenly in- terested, has made severe demands on fishery research because year after year negotiators require prediction of one effect or another of man's pressure on the fish population. Tomeet this demand the authors have written a handbook of all the methodology involved. With the aidof the cases stated and the worked examples given, an approximate solution can be found to any problem of fishery regulation in the world--pro- vided the right data are available; or, if not, this work shows precisely what data areneeded. In, addition to making available adequate knowl- edge of population dynamics to all workers in the field of fisheries, many of the authors! methods will be applicable to other living popu- lations, and their theoretical framework should form part of the syllabus of teaching in agricul- ture, in ecology, in geography, in sociology, and in nature preservation.

The author de- scribes in detail the action of spherical trawl nets, and states that ''With spherical floats itis impossible to increase to any great extent the vertical opening of a trawl at the usual trawling speeds, or to maintain the existing vertical opening at increased speeds. Instead of spheri- cal floats, therefore, it is necessary to use spacing devices in which the hydrodynamic forces of the contrary flow during trawling are utilized. These spacing devices may consist of hydrodynamic floats, sheets of foam plastic, wooden support boards, sheets in the form ofan aeroplane's wing and many other hydrodynamic forms."

OYSTERS: "Pond Culture of Oysters at Bears Bluff Promis- ing," article, South Carolina Wildlife, vol. 5, no. 1, Winter 1958, pp. 4-5, 18, illus., printed. South Carolina Wildlife Resources Department, 1015 Main St., Columbia, S. C. Describes brief- ly the life history of the oyster, the construction of ponds, and the early work in South Carolina on the culture of oysters. The pond culture of oysters was begun in 1944 but had been practi- cally abandoned since 1950, due to lack of funds and personnel and a series of drought years. Since funds from a grant have become available, a one-acre pond has been partially cleaned of accumulated silt and a part of the floor shelled, hardened, and planted with seed oysters. Engi- neering work for the control of salinity is also under way, with pipe lines and a pump installed. The article states that ''In addition to producing better quality oysters, the cultivationand grow- ing of oysters in ponds provides valuable infor- mation, particularly in solving such problems as how to control oyster diseases and predation."

XX, no. 8, March 1958, pp. 154-157, printed, single copy 50 cents. E. W. Williams Publica- tions, Inc., 82 Wall St., New York 5, N. Y. This report presents the results of experiments on the keeping quality of antibiotic-treated fish un- der practical operating conditions existing in fish plants. Storage experiments in fish plants of fillets of rockfish and of sole were carried out, comparing the effect of a 5-percent saline dip with a dip in 5-percent salt solution con- taining 5 or 10 p.p.m. of chlortetracycline (CTC). The CTC-dip treatment definitely prolonged the storage time of the fillets. On being taken out of the water on shipboard, various whole flat- fish were placed in plain ice and in ice contain- ing 10 p.p.m. of CTC until they were landed a- shore. Then they were stored at atmospheric temperature. The preliminary CTC -ice treat- ment aboard ship had a definite prolonging ef- fect on the subsequent storage time compared to fish stored originally in plain ice. The pos- sible influence on the storage times of suchfac- tors as storage temperature, initial bacterial loads, and history of the fish between the time of removal from the water and landing ashore were also briefly discussed.

Kholodil'naia Tekhnika, c/o Four Continent Book Corp., 38 W. 58th St., New York 19, N. Y. Recommendations are made in this article to precool trawled fish in additionally salted sea water at temperatures not lower than -4 C. (+26 F.). The prelimi- nary cooling leads to a 3-4 fold decrease in ice requirements, increasing the effective tonnage of the trawler. The storage life of the fish is in- creased by 3-4 days. Experimental data are presented on the temperature distribution in the fish body (large cod) on cooling in brine at var- ious temperatures. Care should be taken to pre- vent freezing of the fish during cooling.

(Published by the Institute of Food Technolo- gists.) The Garrard Press, 510 North Hickory, Champaign, Ill. Describes an investigation conducted to determine the effects of antibiotics on the retardation of spoilage of sockeye salm- on. Under the conditions of this investigation, oxytetracycline and chlortetracycline retarded the spoilage of sockeye salmon. The over-all storage life appeared to be extended by afactor approximating 1.5 over the cases where no antibiotics were used. Extension of storage time was dependent on temperature. At the high storage temperatures (65 + 5° F)), the ab- solute time of extension was relatively small, while at 32° F., the absolute time of extension was considerable. Chemical and organoleptic examinations substantiated the above conclu- sions. Results of the bacterial examination were inconclusive, probably due to the fact that the samples were stored at freezing tempera- tures prior toexamination. Assays for residual antibiotic activity in the canned product were negative.

In order to find answers to the many problems created by hydroelectric development of Sweden's rivers, the Migratory Fish Com- mittee was formed which collaborated with the Swedish State Power Board and private com- panies in several studies. These studies re- vealed that salmon reared to 6 inches before stocking attained a weight of 4 pounds after 18 months in the sea, 12 pounds at the end of the third year, and 20 pounds after 4 years, and that only 2 of 80 tagged fish recaptured inshore had strayed from their "parent" stream. According to calculations, a return of at least 5 percent would be necessary to make artificial propaga- tion a "paying proposition." SEA MAMMALS: Seals, Sea Lions, and Walruses (A Review of the Pinnipedia), by Victor B. Scheffer, 189 pp., illus., printed, $5. Stanford University Press, Stanford, Calif., 1958. A systematic account of the pinnipeds. Drawing upon man's increased knowledge of life in the sea, especially in the polar regions, and on his greater understanding of the processes of animal evolution, the author has examined in a fresh light the pattern of dis- tribution and variation displayed by the seals and their relatives. Taxonomic history, geo- graphic range, and population estimates are given for each of the forty-seven kinds of pinni- peds, and an attempt has been made to estimate their world population. Pinniped adaptations in body form and function to life in the sea are ex- plained, and the author traces the evolution of the order and its subdivisions from its pre- carnivore ancestors. A synoptic key enables the reader to identify each of the twenty genera on the basis of distinctive features of size and shape, pelage, skeleton, and behavior.

The opinions of the experts vary on whether or not noises scare fish away. It appears that although fish in the immediate vicinity of the noises may be frightened and leave the area, those a short distance away are not affected. Surface-living fish are probably more apt tobe frightened away than bottom-dwellers, but it is unlikely that they stay away permanently. In fact, fish have been observedreturning to anarea soon after explosionshave been set off there. (''Sea Secrets,'' September 1957, The International Oceanographic Foundation, Coral Gables, Fla.)
