The food safety of cultured fish became the focus with the development of aquaculture. Requirements set by FDA that all fishery products must be produced according to HACCP principles. To prevent the disadvantage of fish during the aquaculture process is the critical point to improve the quality of fish. This paper studied the possibility of application of hazard analysis and critical control point (HACCP) principles in recirculating aquaculture workshop. The HACCP group judged the critical control point (CCP) by CCP judging-tree. The results showed that it is possible to apply HACCP to the recirculating aquaculture system. The survival rate of stocking fish was up to 99% and the food conversion rate (FCR) was 1.14.
