The LC50 96-hr of carbaryl, glyphosate, and malathion were equal to 11.69, 6.64, and 0.97 mg L-1, respectively, that were considered as harmful (10.00-100 mg L-1), toxic (1.00-10.00 mg L-1) and very toxic (-1) compounds for this species. The exposure of fries to sub-lethal concentrations of the pesticides over 15 days indicated that the average of ChE activity in the head and trunk were 1086.89 ± 124.34 and 627.36 ± 99.60 mU min-1 per mg protein, respectively, with a significant difference relative to each other. There was a significant difference between fry exposed to all three pesticides and the control group in cholinesterase inhibition. The fries exposed to carbaryl (890.12 ± 28.08 mU min-1 per mg protein) and glyphosate (891.77 ± 31.61 mU min-1 per mg protein) showed lower ChE inhibition than those exposed to malathion (790.00 ± 58.14 mU min-1 per mg protein).}, keywords = {Carbaryl,‎ ChE activity,‎ Glyphosate,‎ Malathion,‎ Rutilus kutum}, url = {https://vrf.iranjournals.ir/article_45634.html}, eprint = {https://vrf.iranjournals.ir/article_45634_f2fe34320353cc06c3d05f76684eba35.pdf} }
