ABSTRACT

The present study was carried out to observe the toxicity of cadmium at various sublethal concentrations in common edible fish, Labeo rohita (rohu) during various exposure periods. Labeo rohita was exposed to sublethal concentrations of cadmium chloride that is 1.0 mg l^-1, 1.5 mg l^-1 and 2.0 mg l^-1 along with control for 24hr, 48hr, 72hr and 96hr. The fishes were sacrificed and muscle was collected for the estimation of total proteins, carbohydrate, lipids and antioxidant enzymes i.e. superoxide dismutase (SOD), lipid peroxidation (LPO) and catalase (CAT) activities. The maximum decrease in protein, carbohydrate and lipid content were found to be 40.44%, 32.17% , 33.12% at 96hr of exposure at 2 mg l^-1 of CdCl₂. Antioxidant enzyme activities were increased when fish exposed to sublethal concentration of cadmium chloride. The maximum increase in the level of catalase, lipid peroxidation, and superoxide dismutase was noted to be 141.2%, 94.6% and 71% respectively at 96hr exposure for 2.0 mg l^-1 of Cdcl₂.The results revealed that cadmium is highly toxic in muscle of Labeo rohita as there was a drastic reduction of biochemical parameters (carbohydrate, protein, lipids) and changes in the level of antioxidant enzymes activities.
