STUDIES ON THE IMPACT OF A MALATHION INSECTICIDE ON CERTAIN BIOCHEMICAL CONSTITUENTS OF A FRESHWATER FISH, LABEO ROHITA
- Malathion, Labeo rohita, biochemical and sublethal study
Malathion is an insecticide which is commonly used for the agricultural and non-agricultural purposes in India. Malathion is found effective for controlling mosquitoes, flies, household insects, animal parasites (ectoparasites) and head & body lice. The effect of insecticide Malathion is found to be highly toxic
even to the non-targeted aquatic organisms including fish. The aim of the study, was to determine the effect of insecticide malathion on some biochemical characteristics (protein, carbohydrate and cholesterol in gill, liver, muscle and kidney) of the fish, Labeo rohita. Toxicity evaluation tests were conducted to determine LC50 values. The 1/10th of 96 hrs, LC50 value was selected as sublethal concentrations (0.5 ppm). All biochemical's parameters were found to be decreased in all tissues on comparison with control. The results indicated the toxic nature of the insecticide malathion.
