Studies on kuruma shrimp culture in recirculating aquaculture system with artificial ecosystem

Abstract The Closed Ecological Recirculating Aquaculture System (CERAS) simulates the food chain of hydrosphere and also includes materials cyclical type of food production systems. In the present study, the nourishment salt form kuruma shrimp aquacultural waste (waste water, foam liquid) collected from the CERAS was used as a medium to raise Chaetoceros gracilis and Tetraselmis tetrathele . F medium was used as a control. The results show that although the growth speed of C. gracilis which cultured in aquacultural waste + Manganese medium was 1 day slower compare with the F medium, there were no significant difference in the lipid composition and the fatty acid, amino acid compositions profile of C. gracilis and T. tetrathele between two groups. Fed shrimp larvae on the algae collected form the two groups for 3 weeks until post-larva stage and collect the shrimp larvae as analytical samples, and then they were divided into two dietary groups and the larvae fed on algae which cultured in F medium was used as a control. There were no significant differences in the larval quality and fatty acid, amino acid compositions profile of shrimp larvae between the two groups.
