Until the 1970s, Lake Victoria had a multi-species fisherydominated by the tilapiine and haplochromine cichlids.There were important subsidiary fisheries for more than20 genera of non-cichlid fishes, including catfishes(Bagrus docmak, Clarias gariepinus, Synodontis sppand Schilbe intermedius), the lungfish (Protopterusaethiopicus) and Labeo victorianus) (Kudhongania andCordone 1974). Stocks of most of these speciesdeclined and others disappeared following theintroduction of four tilapiines (Oreochromis niloticus,Oreochromis leucostictus, Tilapia rendalli and Tilapiazillit) and Nile perch (Lates niloticus) during the 1950s.Since then the commercial fishery in the Uganda portion of Lake Victoria has been dominated by the Nile perch, Nile tilapia (Oreochromis niloticus) and the native cyprinid species, Rastrineobola argentea (Mukene).Issue/Article Nr
