Prior to the introduction of Lates niloticus, a balance between predators and prey species had evolved in Lake Victoria. Adaptations by both predators and prey had ensured that extermination of a species would not occur as a result of predation.
Since its introduction into Lake Victoria, Lates niloticus has become established as the dominant species and now makes up 50% of the fish landings from the lake. L. niloticus demonstrates a natural ontogenic change in diet but also has the capability of adjusting its feeding habits to take advantage of the most abundant food source. In Lake Victoria, as in other lakes where Lates has been introduced, many endemic prey-species have been almost elimimated and the Lates population is now largely cannibalistic.

River Victoria are formed by tectonic actions when you look at the mid-Pleistocene (Fryer and you will Iles, 1972). Read More
