ABSTRACT

The sustainability of fish diversity and its abundance is based on the quality of water existing in that locality. All the hydrological parameters as well as plankton diversity influences the production of fish species. Stocking of economically viable native species of fishes in the reservoirs may convert the reservoirs more productive and is important measure from aquabiotic conservation point of view. The present investigation carried out at Tungabhadra reservoir from Jun 2017 to May 2018. Physico-chemical characters and fish diversity was estimated at topographically different sites. Results revealed optimum ranges of hydrological parameters showing alkaline pH, high Dissolved Oxygen and nutrient richness in all the three selected stations. There was positive relationship between hydrological parameters and the abundance of fin-fishes. Fish composition was dominated by Cyprinids. The rate of abundance was major carps > minor carps > cat fishes > trash fishes.
