Fish processing wastes used as feed ingredient for animal feed and aquaculture feed

Abstract

Fish wastes management has become a global problem from the last years. Dispose of seafood wastes cause environmental pollution. To overcome this issue these unwanted seafood products are used for the formation of animal feed and aquaculture feed. These unwanted products include small fish and those parts of fish which are not used as human food. These unwanted parts include viscera, head, fins and skin of fish.  These byproducts are rich source of protein, minerals and vitamins so these can be used as a supplement in animal feed. These are also used to fulfill the deficiency of protein in animals. These byproducts can be used in the form of fish meal, fish oil, and protein hydrolysates and fish silage. Protein hydrolysates provide high amount of nitrogen and fish oil provide triglycerides of fatty acids and phospholipids in the animal feed industry. These are also used in the formation of pet feed and in the formation of fertilizers. These byproducts are processed for feeding by using fermentation, biotechnological and bio preservation techniques.
