Abstract: This study documents the water quality, habitat characteristics and freshwater fish diversity of Bhavanisagar Reservoir, Tamil Nadu. We recorded 52 species represented by 8 orders, 13 families and 38 genera. The Cyprinid family was found to be dominant in the present study. Various diversity indices have been used to assess the fish diversity. The highest species diversity was found out in Bhavanisagar Dam (S1) and lowest species diversity was recorded in Aapakkudal (S7) sites. Fish diversity was also correlated with physicochemical variables and habitat characteristics. Among 52 fish species collected from 10 study sites of the upstream/ downstream areas of Bhavanisagar reservoir, of which 2 species (4%) were found to be critically endangered, 41 species were least concerned (79%), 5 species were near threatened (9%) and 4 species were in vulnerable category (8%). The threat status of fishes found in the Bhavanisagar reservoir strongly suggests the need for effective conservation measures to conserve the fish species richness.
