Kolavoi Lake is perennial water resource for human consumption also helpful for the agriculture and fisheries in Chengalpet. The study were carried out for one year (April 2012-March 2013), and it was observed that the ichthyofauna belongs to 07 orders 10 families 14 genera and 18 species. Percentage contribution of species to families, Cyprinidae was most dominant constituting (31.5%) followed by Channidae and Siluridae constitute (10.5%) and Anguillidae, Notopteridae, Poecilidae, Anabatidae, Gobidae, Matacembilidae constituting (0.52%) of the total fish species. Various Physico-chemical parameters such, as water temperature, Dissolved oxygen, pH and Alkalinity were at the ranges of 26.2 to 31.5ºC, 7.2 mg/l to 10.5 mg/l, 6.51 to 8.32 and 47.80 to 65.84, respectively, which were suitable for growth of flora and stocking of fish diversity. Keeping a view that ichthyofaunal diversity of Kolavoi Lake is correlated to aquatic ecosystem.
