The effect of ecological changes in Lake Victoria on the present trophic characteristics of Oreochromis niloticus in relation to the species' role as a stabilizing factor of biomanipulation
The Lake Victoria ecosystem has experienced such a profound ecological change that Oreochromis niloticus - an introduced species, is the only important cichlid (out of the original 250 + spp) left in the lake. It is the basis of an important commercial fishery which is intensely exploited by sophisticated methods. An investigation of its feeding habits at present indicates that the species could also playa major role in the energy flux of the lake. Fisheries management in Lake Victoria will thus require multi-disciplinary studies which reflect a total ecosystem approach.
