Abstract
Longitudinal variation in fish species composition at various sites on the Angabanga river showed an increase in diversity from source to mouth and that only a few fish species occur at all sites. The fish assemblage of floodplain pool areas contained fewer species than the main channel and was dominated by two exotic species Oreochromis mossambicus (Peters 1852) and Trichogaster pectoralis (Regan 1910). Most native fish species utilize invertibrates as a food source. The absence of ingenous detritus/substrate feeders in the Angabanga community may account in part for the success of the two introduced species on the floodplain. (AU)....
