Abstract
By-products from fish processing sectors are underutilized or discarded directly into the environment, creating detrimental environmental pollution. However, these bio-wastes have huge potential to be used as other applications. Silage from fish is a liquid type product produced from the whole fish or unconsumed parts of it, to which acids, enzymes or lactic-acid-producing bacteria are added, with the liquefaction of the mass provoked by the action of enzymes from the fish. They are usually produced from dead or spoiled fish species or their wastes and by-products which can be a safer environment friendly technology to solve the waste disposal issues in the fishing sectors. Silages are mainly made by chemical and biological processes that need few types of equipment during processing. Further, high nutritional viability in silages makes their applicability as cost effective animal feeds as well as plant fertilizers.
