[0002] Fish is the best source of animal protein for humans. However, with the increase of human activities, natural fishery resources have begun to fail to meet consumption needs. Industrial fish farming equipment has a large area of ​​water, and fish excrement and uneaten bait will settle at the bottom, causing pollution to the fish farming environment, which may cause fish to die due to the influence of fish farming water, greatly increasing costs. Such a fish farming environment slows down the growth rate of fish. At the same time, there are problems such as deterioration of the farming environment, decline in product quality, and serious diseases of farmed varieties.

[0003] The water in the breeding pond is used for too long or is not changed frequently, which will cause pollution to the breeding pond. The pollution source of the breeding pond mainly comes from the excrement of aquatic organisms and the food residues left over from feeding. Therefore, in order to ensure the survival rate of fish, the fish pond must be cleaned manually frequently to ensure the cleanliness of the water quality. If you choose to change the water frequently, it will cause a lot of waste. The existing fish pond water treatment equipment has relatively simple water treatment and cannot be operated in a circulating manner, which wastes manpower. Utility Model Content
