This study revealed the existing fish species and their composition along with diversity, richness and evenness indices. A total of 66 species of fishes have been recorded belonging to 41 genera, 17 families and 6 orders. Cypriniformes was recorded as the most diversified fish group as well as for number of fish species both. Of all the fishes 2 fish species was endangered, 8 species was rare and 18 species was threatened according to fish catch in river Kamala. Overall values in diversity and evenness indices were as Shanon index 2.08, 3.03 & 3.29, Simpson index 0.81, 0.92 & 0.94. Marglef index 3.95, 9.57 & 10.45 and Evenness index was 0.68, 0.76 & 0.81, respectively.
