摘　　要：The low yield of food production ascribed to harm caused by pests has led to the application of pesticides to food crops. Pesticide residues from the application on crops are mostly found in foods that can cause diseases for consumers of such products. A total of 37 pesticide residues consisting of 15 organochlorines (OC), 13 organophosphorus (OP) and 9 synthetic pyrethroids (SP) were determined. The QuEChERS method was exploited for extraction and clean-up. Gas Chromatograph was used for detection and quantification which was equipped with an electron capture detector and pulse flame photometric detector. The results showed that the mean concentrations of pesticides in fish ranged from 0.007 mg<span style="white-space:nowrap;">·</span>kg^-1 to 1.026 mg<span style="white-space:nowrap;">·</span>kg^-1 for OCs, 0.002 mg<span style="white-space:nowrap;">·</span>kg^-1 to 0.190 mg<span style="white-space:nowrap;">·</span>kg^-1 for OPs and 0.004 mg<span style="white-space:nowrap;">·</span>kg^-1 to 0.032 mg<span style="white-space:nowrap;">·</span>kg^-1 for SP.
