Optionally, the culture pond is divided into a plurality of horizontal culture areas from top to bottom, namely, the plurality of culture areas are distributed in the culture pond in a partially layered manner in parallel.
In the traditional aquaculture technology, the same aquatic species or a few aquatic species with complementary life habits are generally cultured in the same culture pond, so that the uniform feeding and management are convenient, but due to the similarity of the habits of the aquatic products in the pond, the competition of limited living resources and space, such as the competition of resources in the fields of oxygen, illumination, feed, space and the like, is extremely easy to cause during high-density culture. In actual cultivation, the horizontal area of the cultivation pond is limited by the limitation of land and land, and is often fixed, so the depth of the cultivation pond can only be properly deepened to enlarge the cultivation space and improve the yield, however, the demands of aquatic products with similar habits on illumination and oxygen are also similar, the cultivation environment with different depths is influenced by increasing the cultivation depth, and the uniform high-density cultivation of aquatic products with similar habits is not facilitated.
