Abstract: In order to evaluate the eco-economic performance of industrial recirculating aquaculture system of Centropristis striata,the emergy flow chart was constructed by using emergy theory and analysis method,and the emergy distribution of the aquaculture model was analyzed.The results showed that the total energy input of the whole system was 4.77×10¹⁷ sej/a,and renewable resources accounted for only 0.21% of the total energy input.The order of non-renewable feedback resource input to total input emergy was feed>construction>depreciation>power maintenance,while the proportion was 36.37%,20.61%,15.02%,and 3.39%,respectively.The renewable feedback resources accounted for 24.39% of the total input emergy.The net emergy yield ration(NEYR) was 5.198,the environmental load rate(ELR) was 3.065,the output emergy exchange rate(EER) was 5.186,the emergy sustainable development index(ESI) was 1.696,and the emergy index for sustainable development(EISD) of sustainable development was 8.795.The results showed that the economic system of industrial recirculating aquaculture model had a high degree of development and high production efficiency,and agricultural production had been upgraded to the level of industrialization.It was an effective way to improve the sustainability of industrial recirculating aquaculture system of Centropristis striata and reduce the environmental load efficiency by developing special full-price compound feed for recycling water,improving feeding strategy and developing efficient and low-energy recycling water facilities and equipment.
