Evaluation of Impact of Phosphamidon on Protein Status of Freshwater Fish Channa punctatus

In present study, an evaluation of impact of Organophosphate pesticide Phosphamidon on protein content of fish Channa punctatus was carried out. After determination of LC₅₀, the sublethal concentration of phosphamidon (0.005ml/lt) was used for toxicity experiment and soluble and insoluble protein content of different tissues such as muscle, liver, kidney and blood at 24, 48, 72 and 96 hrs exposure was studied. It was found that there was a decreasing trend of both soluble and insoluble proteins up to the end of experiment but maximum decrease was found at 48 hrs. This might be due to proteolytic activity after that there was some rise in level especially in blood and liver suggesting the increased enzyme synthesis to cope with toxic stress.
