It was important to sustainable development of aquaculture industry used biological method and biotechnology to treat the waste of aquaculture. In this paper, an airlift recirculating aquaculture system was designed and polychaete worms was cultured in it. According to the different food level experiment, the growth of Perinereis aibuhitensis was tested in each system which marked M1,M2,M3,M4 and M5 throughout the percent of weight from 0,6%,12%,18% and 24%. The water parameters also were tested. The results showed that : In the M3 groups, production of P.aibuhitensis is the highest as 2.36 g/m 2 ,other groups was negative production. Feded on the residual feeds and feces of flounder fish,worms mean weight was increased,the maximum in M4 was 1.570g and maximal was 0.986g in M3 in the 40 days.The results could give a novel method to biological utilizated the waste of aquaculture.
