The present investigation has been conducted during the period between January to December 2018 to assess the fish diversity profile in freshwater Bhimasandra pond in Tumakuru, Karnataka. It is a natural pond it catches runoff water from the surrounding area and also treated effluent water from water treatment plant is flowing into the pond. In this paper an attempt has been made to document fish biodiversity and composition of fish community in light of physical habitat quality. A total of 24 species belonging to 20 genera, 10 families and 6 orders were recorded. The groups of fishes include major carps (5 species), minor carps (1 species), carp minnows (2 species), Cat fishes (6 species) ornamental (1 species), larvicidal fishes (1 species), snake fishes (1 species), murrels (2 species) and other fishes (5 species). The major carps, murrels, catfishes, minor carps and other fishes are commercially important. Among the collected species Cyprinidae family was most dominant constituting 41.66% followed by Bagridae family with 12.50% of the total fish species. Carp fishes 34.78%, Catfishes 39.13% and miscellaneous fishes 26.09% were observed in the present study. All fishes are useful as food fishes except Ambassis and Gambusia, which are useful as ornamental and larvicidal fishes.
