Systems and methods are disclosed for receiving, processing, and storing fish carcasses. A system comprises a conveyor apparatus, a grinding apparatus, a tank, a container, a refrigerating apparatus, and a power source. The power source may comprise at least one solar panel. The system may comprise a payment apparatus. The tank may be removable from the container. The system may be configured to loaded onto a truck. The system may indicate to a user that the tank is nearly full.

A frozen product of minced fish meat frozen into granules includes: 90 wt % or more of meat granules having a substantially columnar shape with a 3 mm to 7 mm diameter; and 10 wt % or less of meat granules with a short diameter of 2 mm or less. A method of producing the minced fish meat frozen into granules includes: raising the temperature of fish meat which has been frozen at −20° C. or less to a temperature of from −10° C. to −5° C.; mincing the fish meat while maintaining the temperature of the fish meat at −10° C. to −5° C. by using a meat mincer having a feed screw, a plate, and a plate knife at a rotation speed of 200 rpm or less; lowering the temperature of minced fish meat to −20° C. or less; and crushing the minced fish meat frozen at −20° C. or less into granules.

A method for ecological utilization of silver carp, including the pretreatment of silver carp and the process of making canned fish surimi. The fish meat of silver carp is processed canned surimi. The fish heads and bones are heated and undergo enzymatic hydrolysis by enzymes, and the residues of the filtration are prepared for fish bone powder. A filtration membrane is used to reduce the volume of the filtrate to 50% of fish surimi and then the filtrate is frozen to ice. The frozen part can be added to fish surimi. The transparent part from membrane filtration was used to produce protein powder or ingredients for beverages. Fish offal can be used to produce protein liquid fertilizer. Fish scales and skins can be used to produce collagen. The method adopts ecological utilization, which makes the silver carp meat used effectively, including its processed wastes. The method is a closed cycle process such that that no pollutants or wastes are discharged during the process.
