Perch Precariously  

The Daily Nation is reporting that populations of introduced Nile perch (Lates niloticus) in Lake Victoria are dwindling, causing strife for fishermen in Uganda, Kenya and Tanzania. The perch in Lake Victoria were once so numerous that they overwhelmed the lake and many of the native fish that lived there, causing a ripple effect that extended to the lives of the people that live in countries surrounding the lake and spawned a movie about the consequences. Now the perch are getting much harder to find, with fishermen being to forced to venture into the deeper waters of the lake in search of their catch. General consensus is that the drop in Nile perch numbers is likely due to water pollution, which likely doesn't bode well for the other creatures that call the lake home.
