Fish species diversity in Thamirabarani River was investigated from May-October 2018. Ten species belonging to 7 families (Channidae, Anchariidae, Lepisosteidae, Cyprinidae, Anguillidae, Cichlidae and Lesbiasinidae) were identified. The results indicated that in Pottal and Vannarpettai sites were more fish species. Melapalayam and Cheranmahadevi sites were less fish species. Because these two sites were highly polluted. Industrial waste water entering into water body represent a heavy source of environmental pollution in Thamirabarani River. It affects the aquatic fauna. With competing demands on limited water resources, awareness of the issues involved in water pollution, has led to considerable public debate about the environmental effects of industrial sewages discharged into aquatic environments. The present study deals with the fish species diversity .It was concluded that the samples of river water was highly polluted mostly associated with industrial sewage discharge and affect the fish species diversity.
