Abstract :

Many pesticides have been reported that to produce a number of biochemical changes in fish both at lethal and more often at sub lethal levels. Changes accur in ion Concentrations, Organic constituents, enzyme activity, and Endocrinal activity The favorable eco–toxicological properties of cypermethrin are related to their ability to penetrate rapidly and interact with the site of action in fishes. Since synthetic pyrethroid exposure is very common, it is imperative to assess the biochemical changes in the tissues of the organism with reference to the toxicant have been considers by the toxicologists for the chronic effects. Due to chronic effects alterations of energy sources and cycles by the animals is inevitable due to stress and as a whole results change in the system. Hence the present study has been taken to study the effect of cypermethrin 10% E.C. formulation at sub–lethal and lethal concentrations to fish. The gill, Kidney, Liver , Brain and Muscle tissues of the exposed and control fish of cirrhinus mrigala (Hamilton) were selected for Biochemical studies. The results indicate that the liver, a vital organ of carbohydrate metabolism was drastically effected by cypermethrin. In all most all the tissues of the organs i.e. Kidney, Liver, Brain, Muscle and Gill tested at sub lethal concentrations of cypermethrin, a decrease in glycogen value was noticed during the exposure periods. Exposure to sub–lethal doses of cypermethrin 10% E.C, the total protein content was found to decrease in all the tissues. Maximum decrease was noticed in ain and liver at 24 hrs exposure. Same trend was noticed in the same tissues even at 96 hrs exposure. At 48 hrs exposure, maximum decrease was observed in liver and muscle.
