Abstract:
The freshwater fish Ctenopharygodon idella was exposed to sub lethal concentration of synthetic pyrethroid insecticide λ- cyhalothrin for a period of 1, 4, 8 and 12 days. The biochemical parameters of various organs such as gill, muscle, liver, kidney and brain were isolated after stipulated time. The glycogen content and total protein content were observed in test fish. In sub lethal concentrations of λ- cyhalothrin, the glycogen content and total protein content were decreased in all the tissues to compared with controls. In the present study on day 12, the maximum decrease of glycogen content was observed in liver (-36.11%) and minimum decrease was in brain (-17.33%), whereas the maximum decrease of total protein content was observed in brain (-64.13%) and minimum decrease was in gill (-26.57%) respectively.
