Evaluating the toxic effect of an organochlorine pesticide, endosulfan and heavy metal lead on the fingerlings of Indian carp Labeo rohita was the prime aim. Individual and successive exposure of the two toxicants was assessed. 96 hr LC50 studies on pesticide and heavy metal resulted in the sub lethal concentration of 4 ppm and 87.5 ppm respectively. Post exposure estimation of nutritional parameters; total proteins, total carbohydrates and total lipids on muscle, liver, brain and kidney of the fish was done for individual toxicants. The impairment of metabolism was found to be more on lead exposure compared to endosulfan. Successive exposure study of the two environmental stressors was carried out to consider the combination effect on the nutritional status of the test fish.Keywords
