Fishes constitute the major biomass of the aquatic ecosystem. The economy of the aquatic habitats is chiefly composed of fishes, crustaceans and molluscs inhabiting the given ecosystem. In the present investigation, an attempt was made to study the conservation status of the fishes that are naturally occurring in the Tungabhadra Reservoir located at Hospet, Vijayanagara district of Karnataka. The survey was spread across 12 months from June 2018 to May 2019. A total of 76 species, belonging to 50 genera and 20 families were recorded. As per the latest IUCN Red List, six Endangered, six Vulnerable, four Near Threatened, five Data Deficient and fifty four Least Concern fishes inhabit in TBR.
