Problems solved by technology
[0002] When carrying out indoor aquaculture, due to the high density of aquatic organisms, it is necessary to pay special attention to the aquaculture environment to avoid the breeding of bacteria in the aquaculture water and cause the disease of aquaculture products. Filtration will cause a lot of waste of water resources, and the replacement process is laborious, and due to the replacement cycle, the material composition in the water is always changing, and it cannot be in a dynamic balance, which affects the normal growth of aquatic organisms

The present invention discloses a circulating water fish culture system. The circulating water fish culture system comprises a plurality of fish feeding units; and each fish feeding unit comprises a filtering box of a bottom layer and a culture box of a top layer, the culture box at least comprises a first culture box and a second culture box, the first culture box and the second culture box are vertically arranged in sequence from bottom to top, and the bottoms of the filtering box, the first culture box and the second box are provided with sewage drainage holes, the sewage drainage holes ofthe filtering box, the first culture box and the second culture box communicate with a main water pipe by a first sewage drainage pipe, a second sewage drainage pipe and a third sewage drainage pipe,and the main water pipe communicates with an external sewage treatment device. The circulating water fish culture system adopts a circulating water system, so that culture water is in a dynamic filtering state, components in the culture water are in dynamic balance, solid impurities in the culture water are removed in a circulating process, nitrite, ammonia nitrogen and other harmful substances ina water body are reduced, and diseases of aquatic organisms are avoided.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish culture system in circulating water. Background technique [0002] When carrying out indoor aquaculture, due to the high density of aquatic organisms, it is necessary to pay special attention to the aquaculture environment to avoid the breeding of bacteria in the aquaculture water and cause the disease of aquaculture products. This requires constant replacement of aquaculture water, or aquaculture water Filtration will cause a lot of waste of water resources, and the replacement process is laborious, and due to the replacement cycle, the material components in the water are always changing, and they cannot be in a dynamic balance, which affects the normal growth of aquatic organisms. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a circulating water fish breeding system. T...
