Hunan Institute of Fisheries Science (Yuanjiang Base) is located in Yuanjiang City, the hinterland of Dongting Lake. It has a standardized pond of 7.3 hectares and an adjacent 10 hectares of inner lake in the suburbs with abundant water resources. However, the lakes are characterized by eutrophication and poor water quality, resulting in water quality Water shortages, seriously affecting seed breeding and commodity fish farming. To this end, the Institute draws on advanced domestic pond ecosystem theory, combined with the site characteristics, re-design and construction of ecological recirculation aquaculture system. The system has been stable operation for 1 year, its main special
