Poecilia reticulata were exposed to herbicide Roundup Transorb® for micronucleus test, nuclear abnormalities and comet assay. The exposure-concentrations were based on CL50–96 h following 0, 1.41, 2.83, 4.24 and 5.65 μL L−1 for 24 h. Micronucleus and comets were significantly increased in the gill erythrocyte cells after herbicide exposure compared with the non-exposed group. Results showed a gradual increase in the number of damaged cells, indicating a concentration-dependent effect and that this herbicide was mutagenic and genotoxic to P. reticulata and this effect could be attributed to a combination of compounds contained in the formulation with the active ingredient glyphosate.
