Abstract

The Doria beel lies in the geographical ordinates between 26°57'30.58 N latitude and 94°10.02.36'E longitude with elevation 277ft. A survey was conducted on diversity of fish fauna of the Doria beel from January 2011 to December, 2012. Fish samples were collected from various stations of the fish landing site of the study area. During our study period we were encountered 55 species belonging to 7 orders and 19 families. Maximum diversity is observed in the family Cyprinidae which represents 18 species (32.72%) followed by Channidae 6 species, Belontidae and Chacidae each 4 species (7.27 %), Chandidae and Siluridae each 3 species (5.45 %), Cobitidae, Nandidae, Notopteridae and Mastercembelidae each 2 species (3.63 %), Anguillidae, Anabantidae, Heteropneustidae, Gobiidae, Synbranchidae, Siluridae, Claridae, Schilbeidae, Chacidae and Tetradontidae each 1 species (1.81%). According to IUCN red list category, out of 55 species, 41.8 % species are not ealuated (NE), 36.36 % species are least concern (LC), 10.9 % species are near threatened (NT), 5.45 % species are vulnerable (VU) , 3.63 % lower risk near threatened (LRnt) and 1.81% species data deficient (DD)
