Abstract
Fish communities of a 4th order stream impounded by a weir were studied: 58 species were recorded of which 90% occurred upstream while reservoir and downstream accounted for 48% and 43% respectively. The fauna upstream was different from that of reservoir and downstream. Relative abundance of non-cichlids common to reservoir and downstream showed 42% similarity. The longitudinal distribution of 3 non-cichlid populations was different in reservoir and downstream. Non-cichlid species richness was almost similar in reservoir and downstream, but its general diversity and evenness were higher in reservoir than its downstream. -from Authors
