Lambda Cyhalothrin Induced Changes in Protein Metabolism of Various Tissues in Freshwater Catfish Clarias batrachus

The present study was undertaken to find out the effect of synthetic pyrethroid lambda cyhalothrin in liver, muscle, gills, kidney, testis and seminal vesicle of freshwater catfish Clarias batrachus. The fish were exposed to the pesticide for a period of 45 days at a sublethal concentration of 5.768 ppm. Biochemical analysis of total proteins and total free amino acids was carried out on the 15th, 30th and 45^th day of exposure to find out changes in the biochemical constituents due to toxic stress caused to the fish. The results showed a significant decline in total proteins in all the tissues during different days of exposure to lambda cyhalothrin, while total free amino acids showed an increase in liver, kidney and testis, and a reverse trend in muscle, gills and seminal vesicle.
