The present status of the fish stocks in the experimental and commercial/artisanal gillnet fisheries in selected waters of Lake Victoria, Uganda
Lake Victoria had a multi-species fishery dominated until the 1970s by the tilapiine and the haplochromine cichlids, but with important subsidiary fisheries of more than 20 genera of non-cichlid fishes such as Bagrus, Barbus, C/arias, Mormyrus, Protopterus, Synodontis, etc (Kudhongania & Cordone 1974). From about 1930 to 1960, the fisheries of Lake Victoria were managed by controlling the mesh size of gill nets (Graham 1929). Gill nets of mesh sizes less than 127 mm (5 inches) stretched mesh had been prohibited on Lake Victoria because they cropped immature Oreochromis esculentus (Ngege) which were at that time the most important commercial species on the lake (Graham 1929). The catch in the legal 127 mm mesh nets per night was over 30 fish of Oreochromis esculentus prior to 1921; this dropped to 6 and 1.6 fish in 1928 and 1954, respectively,(Beauchamp1955),indicating overfishing ofthe stocks.
