Abstract

For sustainable development of aquaculture industry, it is important to apply biological method and biotechnology to treat the waste of aquaculture. In this paper, an airlift recirculating aquaculture system was designed and polychaete worms were cultured in it. According to the different food level experiments, the growth of Perinereis aibuhitensis was tested in each system with different feeding ratios according to food/total worms’ weight percentage. It was marked as M1, M2, M3, M4 and M5 respectively. The water parameters were also tested. The results showed that in the M3 groups, the production of P.aibuhitensis was the highest being 2.36 g/m2, while other groups exhibited negative production. Fed on the residual feeds and feces of flounder fish, the mean weight of worms increased to a maximum in M4, which was 1.570g and in M3, it was 0.986g in 40 days. The results provided a novel method to biologically utilize the waste of aquaculture.
