Looking down at radiation cell at BCF Gloucester Technological Laboratory. Containers holding fish fillets are on a conveyor belt passing over the cell. The speed of the conveyor belt controls the radiation dose received by the fillets.

Three-mile fish ladder at Cazadero Dam. Power dams have changed the environment drastically. Ladders - some remarkably successful - are one means of maintaining runs of salmon against effects of huge enginnering projects. But not all problems have been solved.

Injecting metal tag into a menhaden. The tag will be recovered later, if the fish is recaptured and reduced to meal and oil. This is part of an effort to maintain the yield of menhaden and many other species. Understanding of variations in abundance of fishery resources and of the effects of manmade and natural phenomena is not complete.

Many fish cannot be harvested with present-day gear because the species are scattered over wide areas. Experiments with pelagic fish show that it may be possible to attract large numbers of fish at night to a series of buoys or rafts with pulsating lights. Then the pulsations would move the fish to a suction hose attached to a factory processing vessel.

For many years, BCF oceanographers have worked with space technology to analyze data from manned and unmanned spacecraft and have related these data to identifying fertile areas in the ocean. Satellite sensing could locate schools of fish and relay this information to fishing fleets. Also, management and conservation of fishery resources could be improved.

Shrimp vessels land the most valuable species taken along the South Atlantic coast. Shrimp trawlers have been modernized and are mainly double-rigged craft that can tow two nets simultaneously, thereby increasing fishing efficiency. Here the trawler is washing its nets after a day of fishing.

Mending a torn pound net. Fishermen often spend much time repairing nets torn by debris or obstacles in the water or rough bottom.

Northern fur seal floating, asleep, with back flippers folded over on left front flipper. The fur seal fishery in the Bering Sea is an outstanding example of successful management. The resource - after overexploitation caused a serious decline - has been restored by wise application of knowledge after many years of scientific research.

Bread made with 10 percent concentrate from hake (center) and herring (right), hardly differ in texture and taste from regular bread (left). FPC can be added to many other products, like macaroni, cookies, vegetable proteins, and starchy foods. About 1 ounce of FPC daily will provide a person with the minimum protein requirement.

The shrimp-like euphausiid (upper) and the copepod occur in many kinds and often in great abundance. These two groups of planktonic animals are of greatest importance as food for larger animals, like fish, squid, or even whales. In the Antarctic, euphausiids are the principal food of the blue whale.

Fertile areas of the ocean swarm with hundreds and hundreds of millions of animal plankton. Some are visible as small dustlike particles; others can be seen only with a microscope. The living zooplankton shown here contain two kinds of copepods - animals shaped like grains of rice - and one kind of arrow worm - the long slender animals at upper right and lower left.
1969 circa
3761 thumbnail picture
The diversity of tiny zooplankton is shown in this microphotograph of preserved specimens. The preserving fluid coagulates the protein and makes the animals look white. In nature the animals are nearly transparent. Some zooplankton live by preying on their fellow members, but most are herbivorous, living on phytoplankton - the vegetation of the sea.

Samples of zooplankton taken at one time and place often consist of only a few kinds of animals. Several species of colorful copepods and one ostracod are shown here.

491Estuaries and their marshlands are necessary as nursery grounds for some of our most valuable fisherey resources. Menhaden spawn in the open ocean , and as the larvae grow they move into estuarine waters where the juvenile stages feed and grow. Yet, marshlands are being "reclaimed" at an alarming rate for industrial and residential development.

Purse seines lead in quantity of fish landed by U.S. fishermen. The purse line, when drawn to the vessel, effectively prevents the fish from escaping under the net. Purse seines are used to catch schooling fish like tuna, menhaden, and salmon. Tuna purse seines (one is shown) are of enormous size, and may be 3/4 mile long, 200 ft. deep, weight 15 tons, and have 10,000 floats.

Scarlet prawns caught by BCF ship OREGON II during explorations for new shrimp grounds off northeastern South America. This large deepwater species is widely distributed on the continental slope between 300 adn 1,000 fathoms in the Gulf of Mexico and the Caribbean Sea. These depths are well beyond the reach of present-day U.S. shrimp trawlers.

The sea scallop - an inhabitant of waters off the Atlantic coast - is a striking example of genetic variation in nature. Though the shape of the shell is uniform, markings and color in this single species vary widely. Selective breeding for desirable traits (e.g., better flesh color or larger size) is one of the goals of artificial cultivation.

A converted ferryboat is used in the Potomac River by the Virginia Institute of Marine Science to test the efficiency of a midwater trawl in catching alewives as they migrate upstream to spawn.

Seining under ice for carp in a "rough" fish utilization operation. Cropping an overabundant fish often leads to better ecological balance and to improved growth of the differenct species in a lake.

Bluefin tuna taken from subsurface waters with longline gear during exploratory fishing by the BCF vessel DELAWARE. Although explorations showed this species to be commercially abundant seasonally during the summer and fall in the Northwest Atlantic, an intensive commercial fishery has yet to be developed.

Lobster pot floats hanging on wall of house. In New England, nearly every port has a group of lobstermen each of whom has his own distinctive colorful floats. Pots belonging to each fisherman can easily be located when they are in the water.

Calico scallops, taken during exploratory fishing off Florida's east coast, spill out of dredge. Successful explorations that locate untapped fishery resources often lead to commercial harvesting.

Blessing the shrimp fleet is an annual event. Shrimp have become the most valuable species in the U.S. fisheries, and more than 2/3 of the domestic catch is taken from Gulf waters. The shrimp fleet has been so improved that it can be considered one of the most modern seagoing fleets in the world.

Scientists are able to determine the age of a fish by counting the number of yearly deposits of bone on the otoliths (ear bones) of fish. Otoliths of the pollock - a codlike fish - are being removed in a study of the growth of the species.

Swordfish caught below surface with longline gear. Exploratory and commercial fishing in the Gulf of Mexico has shown that the fish concentrates in deep water in the fall, winter, and spring off the Mississippi Delta. Profitable catches are being made by U.S. vessels fishing at night.

Sacking 5-pound bags of scallops for freezing. This new fishery - along with shrimp and crab fishing - is helping to diversify Alaska's fishing industry, which until recently depended almost entirely on the highly seasonal salmon and halibut fisheries.

Seining for small fish that will be used as live bait in the skipjack fishery. Nehu, an anchovy, is the most sought-after bait. It is thrown into the water to attract skipjack close to the vessel where they can be caught with pole and line and unbaited barbless hooks.

Sockeye (red) salmon spawning in an Alaska stream. The fish assume brilliant colors as they migrate upriver to spawn.

Fish wheel operated for river basin research on the Copper River. Laws have been enacted to prevent commercial use of wheels, since almost every salmon is scooped up when the fish migrate toward spawning beds. Wheels can still be operated if the fish are caught for personal use.

Aquaculture has the potential to meet a large part of the demand for certain fishery products. A technician at a privately owned facility is holding a bag of shells. Free-swimming oyster larvae (spawned and grown artificially) attach to the shells and are then known as spat. The spat are fed cultured algae until large enough to be placed on natural beds where they will grow until harvested.
