Pesticide Residues in Flesh of Cirrhinus mrigala Collected From a Commercial Farm and River Chenab at Trimu Head, Jhang

Farmed and wild samples of two weight Cirrhinus viz., 501-900 g and 901-1300 g of Cirrhinus mrigala were collected from a Commercial Fish Farm and from river Chenab at Trimu Head Jhang, respectively. The extracted residues were pesticides analyzed through reverse phase high performance liquid chromatography (HPLC) technique. Endosulfan α, p, p’-DDT, methamidophos, carbofuran, diazinon, parathion methyl, dimethoate, malathion, chlorpyriphos, cypermethrin, carbosulfan and isoproturon were detected in farmed fish. All of these pesticide residues except for methomidophos were also identified in the flesh of the wild fish. The level of all pesticide residues was lower than the maximum residue limit but carbofuran exceeded the maximum residue limit (MRL, 0.1 ppm) in farmed (0.11 ppm) and wild fish (0.21 ppm). Total concentration of pesticide residues was found to be highest in farmed (0.06 ppm) as compared with wild fish (0.05 ppm). Higher concentration of pesticide residues was recorded in cultured fish.
