Kawade Sujata

Abstract: Heavy metals are considered as the most important pollutants of the aquatic environment. The present study is planned to determine the protein and glycogen content in the reproductive organs Ovary and Testis of test fish Channa punctatus exposed to two sublethal concentrations of Cadmium (Cd) as CdCl2 for 30 days. The results clearly show the sublethal concentrations of Cadmium significantly decrease the protein and glycogen level in exposed fish Channa punctatus after 30 days as compared with control.
