Toxicants exposure on fish may induce genetic alterations that can be used as genotoxic markers. We evaluated DNA damage using a Single Cell Gel Electrophoresis assay (SCGE), applied on erythrocytes after exposure of Labeo rohita to sub-lethal (0.03 ppm), lethal (0.06 ppm) and acute lethal (0.10 ppm) concentrations of Cypermethrin. Results revealed a significant level of DNA damages at all concentrations tested. Damage index of comet assay in L. rohita’s erythrocytes showed significant differences between sublethal, lethal and acute lethal exposures.
