摘要：Fish faunal bio diversity in the Meghadrigedda reservoir was studied from September-2014 to August-2015. Fish samples were collected once in every fortnight with the help of local fishermen by using local fishing Craftand Gear. A total of 55 species of fishes were identified belonging to 9 orders such as Osteoglossiformes (01 species),Cypriniformes (24 species), Ciprinodentiformes (01 species), Siluriformes (13species), Angulliformes (01 species),Beloniformes (01 species), Channiformes (03 species), Mastacembaliformes (03 species) and Perciformes (08 species).The number and percentage composition of population status were calculated to 36.36% common, 29.09% abundant,20.0% moderate, and 14.55% rare species were identified in the Meghadrigedda reservoir. During this study, 42 speciesof fishes are least concerned (LC), 05 species are near threatened (NT), 04 are not evaluated (NE), 02 species of fishare vulnerable (VU), and 01 each as endangered (ED) and data deficient (DD) were reported. IUCN (2004.2), CAMP(1998) status and Shannon-Weiner diversity (H-), Evenness (E), Hmax = ln(S) Maximum diversity possible and speciesrichness (S) for different months were calculated.
