Eutrophication as a challenge to sustainable capture fisheries: a case study of Oyun reservoir
High concentrations of nitrate and phosphate from run-off of nitro phosphate fertilizers from nearby farmlands were recorded from Oyun reservoir, causing cultural eutrophication which affected the catch and fish assemblages; with high abundance of fish in the dry season and dominance of Cichlids while Heterotis niloticus and Barbus occidentalis were endangered. Management techniques to prevent extinction of its fisheries and sustainable exploitation of the fisheries such as watershed and construction best management practices (BMPs) to control eutrophication and fisheries conservation were suggested.
