Abstract: Present study is an attempt to make a comparison of ichthyofaunal diversity and abundance of a river fed reservoir, the Ramanpad and a rain fed reservoir, the Chandrasagar situated in Mhabubnagar district, Telangana state in India. The study was undertaken between March-2013 and February-2015 covering two hot and two wet seasons. The fish fauna of two reservoirs were collected for the present study. A total of 19 fish species belongs to 3 orders, 16 genera of 8 families were recorded in Chandrasagar and 32 species belong to 6 orders, 21 genera of 11 families in Ramanpad reservoir. In Chandrasagar, the order Cypriniformes was most dominant group represent by 10 species followed by orders Perciformes with 5 species and Siluriformes with 4 species. Cypriniformes was also the dominating order in Ramanpad and is represented by 11 species followed by orders Siluriformes with 9 species, Perciformes 9 species, Osteoglossiformes 1 species, Beloniformes 1 species and Synbranchiformes 1 species. Thus the two reservoirs have good potential for fish fauna. Cyprinidae was the most dominant family and fish diversity was high in Ramanpad and least in Chandrasagar.
