IMPACT OF ZINC SULPHATE ON BIOCHEMICAL PARAMETER IN MYSTUS CAVASIUS
Keywords:
Abstract
In the present investigation, the fresh water fish, Mystus cavasius caught from pariyet lake. Toxicity and biochemical parameters was studied in liver and kidney in comparision to control fish against zinc sulphate. Fish liver and kidney was dissected out and analyzed for various biochemical parameter like total protein and glycogen. The lethal concentration (LC50) value of zinc sulphate was 8 mg/l for 96 hours exposure. Mystus cavasius were exposed to three sub-lethal concentrations of zinc sulphate (2 mg/l, 2.5 mg/l and 3 mg/l) for 10 and 20 days. Protein content in the liver and kidney was found decreased due to proteolysis induced by zinc sulphate. The liver glycogen also declined.References
