S. Logaswamy, Shijitha J Nambiar and K.M. Remia

Abstract

The effects of organophosphorous pesticides malathion and quinalphos, on some biochemical parameters of fresh water fish, Tilapia mossambica were investigated under sublethal toxicity in the present study. LC50 vaule of malathion and quinalphos were 3ppm and 14ppm respectively for 24 hrs treatment. Biochemical parameters like glucose, protein, cholesterol and electrolytes were analysed in the blood of fish and all the parameters showed significant changes. The present findings clearly indicate that even sublethal concentrations of malathion and quinalphos produce dysfunction of many physiological and biochemical processes in fish and compensatory mechanisms are induced to meet the energy demand of the cell resulting from the pesticide stress.
