Abstract: The present study was undertaken to find out the toxic effect of synthetic pyrethroid lambda cyhalothrin on the functioning of endocrine glands in 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. Analysis of hormone profile was carried out on the 15, 30 and 45 days of exposure to find out the alteration in hormone secretion and the response of the fish to the compound. The results obtained showed a significant decline(p<0.05) in levels of thyroid hormones and testosterone while a significant increase (p<0.05) was observed in cortisol levels during the different days of exposure of the fish to lambda cyhalothrin.
Key words: Lambda cyhalothrin, Thyroid hormones, Cortisol, Testosterone, Clarias batrachus
