Interpretive Summary: Fish processing by-products refer to tissues that remain after much of the fish muscle has been removed and include heads, frames, viscera, and skin, among others. Edible parts such as heads, milt, and stomachs are on occasion collected and sold and some fish skin is made into gelatin or fish leather. By-products can be used to make fertilizer and other products; however, most of the fish by-products produced in large shore-side fish processing operations are used to make fish meal and fish oil. Primary uses of fish meals and oils are as aquaculture feed ingredient for fish and shrimp, and as livestock and poultry feed ingredients. This chapter deals with making aquaculture and animal feed ingredients from fish processing by-products and focuses on by-products currently produced from marine finfish.

Technical Abstract: Alaska fish processing by-products can be used to make fertilizer and other products; however, most of the fish by-products produced in large shore-side fish processing operations are used to make fish meal and fish oil. Primary uses of fish meals and oils are as aquaculture feed ingredient for fish and shrimp, and as livestock and poultry feed ingredients. This chapter deals with making aquaculture and animal feed ingredients from fish processing by-products and focuses on by-products currently produced from marine finfish. Included are sections on making feed ingredients from processing by-products, different by-product components obtained from the processing of finfish, processes used to produce protein meals, solubles and oils from fish processing by-products and the production of hydrolysates and silages.
