MARINE PRODUCTS OF COMMERCE 



the same year amounted to 10.1 million povmds of Pacific oyster meats, which 

 were sold fresh and canned, and 151 thousand pounds of native oyster meats 

 which were marketed fresh. 



The crab fishery is based chiefly on the blue crab found on the Atlantic and 

 Gulf Coasts, the Dungeness crab of the Pacific Coast, and the king crabs of 

 Alaska, which have been sought by U. S. fishermen only since 1940. The blue 

 crab catch in 1945 was 102 million pounds, most of which was marketed as fresh 

 picked meat. Dungeness crab production of 17 million pounds was marketed as 

 cooked meat, canned, and cooked in the shell. King crab production is very 

 small, though increasing. Marketing forms include frozen picked meat, frozen 

 cooked in the shell, and canned. 



Fish meal and oil, condensed fish solubles, liver and viscera oils, glue, pearl 

 essence, marine plant products, such as agar, Irish moss, alginates, etc., and shell 

 products represent the more important items generally classified as by-products 

 of the United States fishing industry. In 1948 there were 298 plants involved in 

 the manufacture of by-products (Anon., 1949e). 



Fish meal, a negligible amount of scrap, and fish body oils are produced from 

 whole menhaden, herring, and pilchards, as well as from the processing waste 

 from pilchards, "ground fish" (cod and related species), rosefish, tuna and 

 mackerel, Maine sardines, and a number of less important sources, such as salmon, 

 blue crab, shrimp, etc. In 1948 199,519 tons of fish meal and scrap, valued at
