Abstract : Freshwater fish diversity, abundance and the heightening effect of the Roseires reservoir, was studied from May 2010 to March 2011 in six sampling sites using experimental fishing nets. The present study has shown that Roseires reservoir supported a total of 34 species of fishes of 13 families were recorded. Among identified fishes, fishes belonging to family Mormyridae were dominated with (7 species) followed by Characidae with (6 species), Cyprinidae with (5 species), Bagridaewith (4 species), Schilbeidae with (3 species) and Cichlidae with two species. According to the relative abundance of fish species Synodontisspecies as the dominant (42.43%), followed by Latesniloticu (12.06%) and thirdly Oreochromisniloticus (6.17%). The potential of the fisheries in the future dam- reservoir (After Heightening) will depend on the area impounded and the dimensions. It will surely be raised at least, may be about two times to the present estimated potential in reservoir; depending on the total surface area to be covered with water. Expected fish species composition will not be very different from the known present status in the reservoir, as the present survey, recovered similar species composition, since the first impoundment, with only slight changes.
