Abstract: Organophosphate pesticide methyl parathion is the most commonly used pesticides worldwide in the pest control of crops. Freshwater fish, Labeo rohita is an important fish species popularly called rohu in Tamil Nadu region having good nutritional values. Fishes living in close association with may accumulate pesticides. To analyze total protein content in fish Labeo rohita exposed under organophosphate pesticide methyl parathion. Present study, toxic effects of the pesticide methyl parathion LC50 4.5 ppm was observed. The 10% and 30% sublethal concentrations of total protein content in the tissue of gill, liver and muscle of freshwater fish, Labeo rohita were estimated. Toxicity effect of methyl parathion resulted in decrease of total protein in all concentration of time intervals. Lowest total protein content was observed gill tissue and highest protein content were observed in muscles. Decrease was more pronounced with increasing time of exposures. There is decreased in all tissues of total protein content increasing exposure periods compared with control fish Labeo rohita. Present results indicated the toxic nature of the pesticide methyl parathion. Therefore it is advised to pesticide workers to take all precautions regarding protection from pesticide exposure and proper use of prophylactic supplementation for their healthy life.
