The Nile perch was introduced to Lake Victoria in East Africa in the 1950s, and since then it has been fished commercially. It is attributed with causing the extinction or near-extinction of several hundred native species, but as Nile perch stocks decrease due to commercial fishing, at least some of them are making a comeback. Initially, the Nile perch's diet consisted of native cichlids, but with decreasing availability of this prey, it now consumes mainly small shrimp and minnows. |
