[Killietalk] Lake Victoria Perch eating killies

["unclescott" <unclescott at prodigy_net>]

Is L niloticus native to Senegal? I read that the range of Ep. bifasciatus,
one of the most widely distributed African killies, reaches across the
savanna to the Nile or at least the upper Nile drainage. If they were a part
of the "natural" order of things in Senegal then there should also be
predators of the L. niloticus.

Would these be sub-adult Nile perch or fry preying upon the Epiplatys?

The pupfish of the Salton Sea, Cyprinodon macularis, were reported to be at
great risk from Tilapia (zillii) because the young Tilapia compete with the
pupfish for food. The adult Tilapia may dine on the adult pups. The zillii
are now being replaced by Oreochromis mossambicus which is even worse news
for the pupfish.

Thanks and all the best,
Scott Davis
