Abstract
The present study was conducted for the ichthyofaunal diversity of Wan River. Wan river is one of the major tributaries of Purna River which ultimately meets to Tapi River. The study was conducted during January 2013 to December 2014. 21 species of freshwater fishes and 22 taxa was identified during this study. The Ichthyofaunal diversity spans through 8 families and 5 orders. This type of studies should be carried out frequently to get dynamics of freshwater ecosystem. Changes in ichthyofaunal diversity can be used to know the changes in freshwater ecosystem as ichthyofaunal diversity is largely dependent on available food sources and predators present in given ecosystem.
