Abstract: The present disclosure provides a recirculation aquaculture system and method. The system includes a fish pond and a fiber turntable filtering system. The fiber turntable filtering system can implement can remove large particles in aquaculture water and regularly harvest microalgae, water quality after treatment reaches a fishery aquaculture standard, and 97% of the aquaculture water can be directly recycled. In the present disclosure, during in-situ culture of microalgae and fish, microalgae can convert CO2 exhaled by fish and nutrients such as nitrogen and phosphorus in the aquaculture water into substances of algae cells, such as proteins, polysaccharides, vitamins, and lipids, and release oxygen, so as to quickly improve quality of the aquaculture water; in-situ culture of the microalgae and the fish gives play to the advantages of high photosynthetic efficiency of the microalgae, and the fast-growing microalgae provide a suitable growth environment for the fish.
