Bioaccumulation and toxicity of cadimium and copper singly and in combination to seabass (lates calcarifer)

Abstract

Experiments had been conducted on seabass (Lates calcarifer) to determine the bioaccumulation and toxicity of cadmium and copper singly and in combination. Toxicity tests were conducted with 2 different salinities, 5ppt and 15ppt. Approximately 10 times more acute toxic effect were observed in the toxicity test at lower salinity of 5ppt exposure. At 5ppt salinity, the 96-h LC50 values of cadmium and copper to seabass (Lates calcarifer) singly was found to be 1.56 mg L- 1 and 2.43 mg L-1.
