Specific to the problem that the construction and operation cost of the freshwater industrial recirculating aquaculture system is too high and the application is restricted to a certain extent, based on independent research and development of the multiway gravity device, the internal circulating fluidized bed reactor, the integrated ozone contact reactor and other water purification equipment, material balance related principles are applied for accurate design and establishment of different stages of key operating parameters of the system to establish an energy efficient industrial recirculating aquaculture system for sturgeon. After the test of 96d breeding, the results showed that the feeding and growth of sturgeon were normal, and the average breeding density was (41.2 ±2.3) kg / m3, the survival rate was 95.8% and the feed coefficient was 1.17. The daily quantity of water exchange was below 5%, the water quality was good, and the ammonia nitrogen and nitrite nitrogen in the later period were stabilized at (0.80 ± 0.21) mg/L and (0.38 ± 0.12) mg/L respectively. Average daily power consumption of the system was 33.3 kW· h, and the average output of 1 kg sturgeon required power of 7.30 kW · h. The system operation is characterized by low energy consumption and high efficiency, thus it can provide technical support for recirculating aquaculture of sturgeon.
