A texturized sinking shrimp and fish food is produced in the form of an extrusion cooked, cellular produce which is self-sustaining in ambient temperature water for a period of at least four hours and is made up of a mixture of at least 8 percent marine meal with up to 60% vegetable protein flour. The product is prepared by mixing and then partially cooking the starting materials in a preconditioner and then introducing the precooked mixture into an extruder (preferably of the twin screw variety) for texturization. During extrusion, the protein within the mixture is developed into laminar striations, which ultimately yields a layered, open-celled, high protein product having a specific gravity greater than 1.00 which will not readily decompose in water during consumption by the shrimp and fish.
A texturized sinking food for marine life, comprising at least about 8% by weight marine meal, said food having a specific gravity greater than 1.00 so that the food sinks in water, a protein dispersibility index of less than 15%, and a plurality of interconnected heat-denatured proteinaceous layers defining a plurality of open cells therewithin said food being self sustaining in water for a period of at least 4 hours, said cell-defining layers consisting essentially of heat-denatured protinaceous material.
