In this study, four immune parameters of scallop to salinity changes were investigated. The scallops were temporarily cultured at different salinity levels 40‰, 35‰, 30‰ for 7 days , and the activities of lysozyme (LZM), superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) were recorded to evaluate the immune capacities to salinity changes(from 40‰ to 35‰, 35‰ to 30‰, 30‰ to 25‰, 30‰ to 35‰ in 5 days respectively). Result shows that the changing of 4 immune parameters were almost the same. LZM activities decreased significantly and then increased, finally remains above the control level; SOD activities significantly decreased and then increased to the control level; Activities of CAT decreased significantly and then increased, finally decreased to the control level; Activities of GSH increased significantly in a short time then increased significantly; finally decline to the control level; The above results demonstrated that salinity change could significantly affect the immune parameters of scallop.
