Abstract
Bangladesh is rich in freshwater biodiversity, but information on riverine fish diversity is lacking. This study represents a complete list of fish species of Dhepa, Punarbhaba, and Atrai rivers of Bangladesh based on surveys carried out for seven years, from 2009 to 2016. A total of 121 species belonging to 80 genera and 33 families were recorded, of which Cyprinidae was the most dominant family representing 24 species. A total of 42 threatened species and 10 exotic species were collected during the survey. This study highlights that Dhepa, Punarbhaba, and Atrai are critical habitats for many conservation-concern fish species, and reveals the need for developing suitable conservation and management plans for the future.

Fish species were identified by experienced fish biologists (Mohammad Shaifuddin Shah, Mostafa Ali Reza Hossain, Imran Parvez, and Mohammad Mahbubul Hassan) based on morphometric characters and meristic counts mentioned in Talwar & Jhingran (1991) and Rahman (2005)
A total of 121 species belonging to 80 genera and 33 families were recorded during the study and are listed together with details of their IUCN status and habitats in Tables 1 and 2
