Figure. The Nile perch is a menace to endemic cichlids

Caption

Pictured on the left is the Nile perch, a voracious predator introduced into Lake Victoria by humans to satisfy meat demands in the 1950s. On the right, several species of endemic cichlids that were markedly affected are shown. The populations of some of these species declined so much that their genomic structure remained significantly altered even after　their numbers climbed back up.
