While achieving these brilliant achievements, my country's aquaculture industry is unbalanced in quantity, scale and quality, and the development of quality and efficiency is insufficient. The main contradiction of my country's fishery is becoming more and more prominent, mainly reflected in the people's concern for high-quality and safe aquatic products and the beautiful water ecological environment. The structural contradiction between the demand for fishery and the supply of aquatic products, as well as the contradiction between the excessive utilization of resources and the environment by fisheries, these main contradictions have brought severe challenges to the sustainable development of the aquaculture industry. If the solid particles cannot be discharged in time, the content of ammonia nitrogen and nitrite in the water will increase, causing the disease of fish and shrimp, such as: iridescent virus, white spot syndrome virus, vibrio, sporozoites, etc., reducing the production and quality of aquaculture. Fishing drugs will also lead to further disturbance of the aquaculture water system and damage the self-healing ability of the ecological environment. At present, the drainage devices and sewage devices in most domestic farms are integrated, and the drainage and sewage are completed by plugging and unplugging the vertical pipes, and then the discharge of the circulating water of the fish pond is controlled by the switch of the valve of the aquaculture pond. Although this method is more convenient, the sewage discharge effect is not ideal, and it is easy to pile up residual bait and manure at the bottom of the pool for a long time, causing damage to the aquaculture water environment and waste of water resources.
