Abstract: The aim of this study was to investigate the sub-lethal toxicity of a monocrotophos organophosphate insecticide effect of muscle and liver tissues fatty acid profile of Channa striatus. To evaluate the toxic effects of monocrotophos organophosphate insecticide from agricultural application, monocrotophos organophosphate insecticide contained sub-lethal concentration of 96 hours of monocrotophos organophosphate insecticide exposure was 0.98 ppm and 1 ppm, duration of 15 day and 30 days for mural, C. striatus. The sub-lethal concentration used for monocrotophos organophosphate insecticide was disturbed biochemical parameters and produced liver and muscle tissue fatty acids damages. In muscles and liver tissue estimation monocrotophos insecticide effects significantly (P>0.05) decreased in crude protein and carbohydrate. Free fatty acid profile of C. striatus of saturated (SFAs), mono unsaturated (MUFAs) and poly unsaturated fatty acids (PUFAs) were increased in muscle tissue 0.98 ppm 30 days and liver tissue 1 ppm 15 day while compared to control. Estimation of muscle and liver tissue saturated fatty acids (SFAs) as capric acid methyl ester, caprylic acid methyl ester, undecanoic acid methyl ester and tricosanoic acid methyl ester were decreased level of monocrotophos 50% insecticide treated groups when compared to control. Simultaneously, palmitic acid methyl ester was increased in muscle and liver tissue of 1ppm 15 days and 1ppm 30days, while compared to control, respectively. In conclusion, modify observed among the chemical composition, fatty acid profile and free fatty acid investigation of muscle and liver in toxic effect of monocrotophos 50% insecticide of gas chromatograph evaluation.
