Bioremediation in Pseudosciaena crocea cage-farming areas by the cultivation of Saccharina japonica

In order to establish ecological aquaculture model of Pseudosciaena crocea,a tentative experiment of bioremediation in Pseudosciaena crocea cage-farming areas by the cultivation of Saccharina japonica was employed for reducing the inorganic N and P elements in the nutritionally enriched sea water in Sandu'ao,Fujian Province.Continuous fixed point and fixed time detection of sea water showed that S.japonica fundamentally repaired the enriched sea water,while the concentration of dissolved oxygen were significantly increased and the inorganic N and P were distantly reduced comparing with the control of non-bioremediation area in the course of experiment.These results suggested that the combination culture of P.crocea and S.japonicawas was an effective and healthy cultivation model for the sustainable aquaculture of P.crocea.
