Shrimp head waste (SHW) is rich in protein (40.37%) with excellent amount of amino acid which can easily be incorporated in fish feed preparation by replacing fish meal. The utilization of SHW is limited due to the presence of crude fiber (chitin) which interferes in digestibility of fish. This problem may be overcome through bio-fermentation using Bacillus subtilis (FPTB-13) which can reduce this crude fiber by the breakdown of glycosidic bond between protein and chitin converting the product easily digestible. Fermentation of shrimp head waste in biofermenter increases the amount of available protein with proper proportion of amino acid and reduces the fermentation time substantially as compared to conventional method.
