Lambda-Cyhalothrin Induced Protein Alternations in Etroplus suratensis (Bloch)

Lambda-cyhalothrin (trade name Karate) is a pyrethroid insecticide, widely used to control insect pests in agriculture, public health, and homes and gardens. In the present study, an attempt has been made to study the effect of lambda-cyhalothrin on protein content of different tissues like liver, muscle and brain of the edible fish Etroplus suratensis (Bloch). The E. suratensis fishes were exposed to different sub-lethal concentrations of lambda-cyhalothrin for a period of 60 days. From the result, the protein content in the tested tissues of E. suratensis was found to decline with increasing sub-lethal concentrations of lambdacyhalothrin. It is concluded that, lambda-cyhalothrin induced deleterious effect on E. suratensis. Therefore, the use of lambda-cyhalothrin in the field may be a threat to fish population and also other organisms including human beings through food chain.
