Abstract: The aim of this study was to investigate the sub-lethal toxicity of a methomyl-based insecticide effect of muscle and liver fatty acid of Channa Striatus. Methomyl-based insecticides were treated sub-lethal concentration of 96 hours of methomyl exposure was 1 ppm and 2ppm, duration of 15 day and 30 days for murrel, Channa striatus. The liver and muscle tissue fatty acids were analyzed. In muscles and liver tissue estimation methomyl 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 1ppm 30 days and liver tissue 2ppm 15 day while compared to control. Estimation of muscle and liver tissue saturated fatty acids (SFAs) as caprylic acid methyl ester, capric acid methyl ester, undecanoic acid methyl ester and tricosanoic acid methyl ester were decreased level of methomyl 40% insecticide treated groups when compared to control. Simultaneously, palmitic acid methyl ester was increased in muscle and liver tissue of 1ppm 15 days and 2ppm 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 methomyl 40% insecticide of gas chromatograph evaluation.
