A total of 7 fish species belonging to 2 orders were recorded. The maximum fish diversity and dominance was reported in the cyprinids. Two species of order Cypriniformes, Tot putitora (Ham.) and Barilius bendelisis (Ham.) were recorded at all the three sites, although they were more abundant at sites I and II. Among the Barilius spp., Barilius bendelisis (Ham.) was the most common at all the study sites, while Barilius barna (Ham.) and Barilius vagra (Ham.) were only found at Ⅰand Ⅱsites. The pool habitat was the most preferred habitat of almost all the species with ('H'=0.521-0.594) tbllowed by rapid and riffle habitat respectively.展开更多
