Abstract:
Pesticides have been one of the most effective weapons discovered by man to protect agricultural products from the attack of pests. As the results of the survey conducted among the farmers and fishermen of the lower Kuttanad area, Fluben Diamide is found to be a widely used pesticide in the paddy fields of Kuttanad, ‘the rice bowl’ of Kerala. Etroplus maculatus is said to be an important freshwater teleost food fish inhabiting the intricate canals and polders of Kuttanad. So, in the present study, an attempt has been made to estimate the lethal toxicity of the pesticide Fluben Diamide on the juveniles of fish Etroplus maculatus, and to analyse the sublethal effect of the pesticide on their Gill and Liver tissue. The histological changes observed in all the tissues of E.maculatus indicate that sub lethal concentrations caused moderate to severe alteration in gill and liver which are important organs performing vital function like detoxification, respiration etc. The application factor derived from the laboratory studies can be directly applied to the field situations, as the fishes are the true inhabitants of Kuttanad.
