摘要

Hakaluki haor is the largest haor in Bangladesh and enrich in fish assemblage where this study has been conducted from January to December 2013. The occurrences of 83 species of fishes in the haor have been recorded belonging to 55 genera, 28 familiesand 10 orders. Forty one threatened fish species for Bangladesh were recorded from the study area. This study disclosed the fish species and their composition along with diversity, richness evenness and dominance indices. Cypriniformes was found to themost dominant order comprising 73% followed by siluriformes (13%) and perciformes (9%). Among the found fishes, 49.40% species were considered threatened in Bangladesh, which include 14.46% vulnerable, 21.69% endangered and 13.25% critically endangered species. Overall values of Shannon-Weaver diversity (H), richness (D), Evenness (e) and Dominance indices were found to be 2.53, 5.94, 0.66 and 0.081, respectively. In order to conserve available fish species, both threatened and non-threatened species, establishment of fish sanctuary is suggested.
