before distribution to the markets through- 

 out the country. The silver hake, when 

 combined with other ingredients, was found 

 to be an economical and satisfactory food 

 additive for the domestic mink. Fish for 

 this purpose are landed whole, washed, and 

 frozen immediately in 50-pound cartons for 

 sale to the mink farmers in the United 

 States. Silver hake, along with many other 

 species, are utilized for industrial pur- 

 poses. Important industrial uses include 

 the making of fish concentrates for fish 

 meal or flour used in poultry and other 

 animal food. Large reduction plants are 

 located in or near the major fishing ports 

 along the Atlantic coast to process these 

 species. 



In the last 10 years, technological de- 

 velopments in handling, processing and 

 analyzing fishery products from the time 

 caught until delivered has advanced rapidly.

No longer are fishery products sold com- 

 mercially without some technological re- 

 search and quality control standards to aid 

 the industry and public. Biochemical tests 

 made at the Technological Laboratories of 

 the Bureau of Commercial Fisheries in 

 Boston and Gloucester, Massachusetts, have 

 included detail analyses of the protein.
