This study assessed the effect of fenvalerate pesticide on the kidney condition Renatosomatic Index (RSI) of a freshwater fish Clarias batrachus. Fenvalerate is a pyrethroid pesticide. The RSI showed decreasing trend when the fishes were exposed to different sub lethal concentrations i. e., 0.02 ppm, 0.04 ppm and 0.08 ppm of fenvalerate for 96 hours. This condition of kidney of the fish can result from incomplete elimination of the fenvalerate from the kidney, thereby affecting the normal metabolism of the fish. Thus, the pyrethroid pesticide such as fenvalerate should be used with caution in agriculture field applications, as it is likely to introduce acute levels of the toxicant into the environment.

Abstract


This study assessed the effect of fenvalerate pesticide on the kidney condition Renatosomatic Index (RSI) of a freshwater fish Clarias batrachus. Fenvalerate is a pyrethroid pesticide. The RSI showed decreasing trend when the fishes were exposed to different sub lethal concentrations i. e., 0.02 ppm, 0.04 ppm and 0.08 ppm of fenvalerate for 96 hours. This condition of kidney of the fish can result from incomplete elimination of the fenvalerate from the kidney, thereby affecting the normal metabolism of the fish. Thus, the pyrethroid pesticide such as fenvalerate should be used with caution in agriculture field applications, as it is likely to introduce acute levels of the toxicant into the environment.
