Aquatic livestock breeding system and method

The invention provides an aquatic livestock breeding method and an aquatic livestock breeding system. According to the aquatic livestock breeding method and the aquatic livestock breeding system, water temperature can be adjusted, and breeding density can be improved. Aquatic livestock is bred in a first breeding layer, and water is pumped from a water layer below the first breeding layer and conveyed to the first breeding layer, flows out after flowing through the first breeding layer, and brings out the breeding solid waste generated in the first breeding layer. The water flowing out of the first breeding layer is injected to a second breeding layer below the first breeding layer, and the breeding solid waste which is generated in the first breeding layer and is brought out by the water serves as fodder for the aquatic livestock bred in the second breeding layer. According to the aquatic livestock breeding method and the aquatic livestock breeding system, the water temperature of the first breeding layer is
