Abstract：To enhance aquaculture eficiency and resource utilization，this study systematically analyzes the technical characteristics and production performance of recirculating aquaculture systems （RAS）. Through three parallel 50m3 experimental systems，a l8o-day empirical investigation was conducted on RAS's water quality regulation capacity， biological growth performance，and facility operational efficiency. Results indicate that RAS achieved： 47% improvement in water parameter regulation compared to traditional aquaculture， 15.5% increase in species survival rate，and water reuse efficiency while reducing comprehensive energy consumption by 45% versus conventional models. Economic feasibility analysis reveals a 3.2一year payback period for scaled RAS projects，demonstrating significant economic and ecological benefits.
