    Description: 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.

    Description: Man-made lakes inhabit diverse species of which the fish fauna constitutes the most targeted species of exploitation. For man-made lakes to serve as means of alleviating poverty an enhancing food security through increased fish production in Nigeria, sound management of the lake is strongly recommended. It will include the maintenance of good water quality, stocking with good species, control of over fishing, conservation of extinction and declining species as well as adequate legislation to regulate fishing activities. Recreational and tourism facilities can also be incorporated along with fish production in these man-made lakes to provide additional income and revenue for individual and Government. Some other practical ways by which these water bodies can be improved for effective and sustainable fish production as well as alleviating poverty was discussed
