ANSWER
The Nile perch (Lates niloticus),2 was reportedly transplanted into the Ugandan waters of Lake Victoria in the late 1950s and early 1960s. Opponents pointed out that such a step made little ecological sense: the theoretical potential sustained harvest from predatory fish (at the top of the food/energy pyramid) is significantly less than from their prey (typically represented at the middle or lower levels of the pyramid). Others argued that Nile perch, feeding on the huge but relatively unexploited and unpopular species stocks of haplochromine cichlids, would eventually provide the Lake with an important new fishery. Indeed, certain reports give the impression that Lates was first introduced with just such an objective in mind (e.g. Acere 1985). However, the circumstances of its original appearance in the Uganda part of the Lake, first noticed in May 1960 even as the debate on transplantation continued, still seem somewhat mysterious. Some authorities consider that disastrous and irreparable harm has been caused to the Lake fisheries by Lates. Its voracious habits have drastically reduced the stocks of a rich and varied indigenous fish fauna, especially amongst cichlid herbivores and detritus feeders. It is argued that these latter species represented important subsistence and commercial resources for lakeside population and provided ecologically efficient fisheries, since short food chains were involved.
