Impact of Carbaryl on Blood Protein and Glucose Content of a Freshwater Fish Heteropneusteus fossilis

Carbaryl, a carbamate insecticide has been one of the most commonly and extensively used insecticide in recent years. It is moderately toxic to the aquatic animals. In this study experiments have been performed to see the toxicity of carbaryl at a sub-lethal concentration of 0.04 ppm on blood protein and glucose level of fish. Protein and glucose content in the blood of Heteropneustes fossilis exposed to sub-lethal concentration of carbaryl (0.04 ppm) for 7, 15 and 30 days, and blood protein was studied. A gradual decrease in protein and glucose content was observed during the experimental period.
