With the exploding human population, India will have to utilise all its avenues for increasing its food production. Fishes form an important element in the economy of many nations as they form a staple item in the diet of many people Most of the water bodies which form the major life support systems of many organisms are facing ecological degradation today due to irrational interference and unsustainable developments. As fish constitute almost half of the total number of vertebrates, it is very important that their diversity is preserved. Hence the present study was conducted to analyse the fish diversity in Aathivayal lake in Tamil Nadu. A total of 154 fishes belonging to 12 different families were identified. Among the various families, Cyprinidae recorded the highest species richness (7 species), followed by Channidae (4 species) and Bagridae (2 species). All the other families were represented by only one fish species. In terms of percentage, Cyprinidae represented 54% of the total fish population followed by Channidae (10.67%), Anabaenidae (9.7%), Bagridae (7.76%), Cichlidae (5.82%) and Claridae (4.85%) while the remaining families comprised less than 2% each.
