Bioaccumulation and Biochemical Response of Liza parsia to Copper

J. S. I Rajkumar, Samuel Tennyson

The test organism Liza parsia exposed to copper concentrations in static bioassay was evaluated to study toxicity, bioaccumulation rate and oxidative stress responses. The 96-hour LC50 was found to be 1.25 mg/l (0.883-1.672) in static renewal bioassay. The bioaccumulation study revealed significant increase (P<0.05) in the accumulation of copper in L. parsia with increase in the ambient concentration. L. parsia accumulated 3.38, 16.45, 27.10, 48.85, 86.18 and 175.62 g/g dry weight of copper in 0.5, 1, 2, 4 and 8 mg/l of exposed copper concentrations. Significant (P<0.05) decrease in concentration of protein and acetylcholinesterase activity, and significant (P<0.001) increases in lipid peroxidation content and catalase activity was recorded. Lipid peroxidation and catalase were found to be the promising biomarkers in heavy metal pollution with special reference to copper.
