Pond culture is one of the main forms of aquaculture. Since the 1970s in China, fish pond culture, shrimp and crab pond culture, and aquaculture fry pond cultivation have flourished successively in China. The aquaculture water body is about 10 billion cubic meters , Such a large scale of farming has made great contributions to the development of my country's aquatic economy. Existing aquaculture ponds are mainly rectangular in shape with a uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds that are equipped with water stirring and aeration machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of the pond far away from the inlet and outlet often become dead corners, the water quality in the pond is not uniform, and the local area is often hypoxic In this state, the cultured organisms cannot obtain a suitable growth environment, and diseases frequently occur, the production speed is slow, and even the breeding capacity decreases, and the production efficiency is low.
