History

Nile perch, (species Lates niloticus), large food and game fish of the family Centropomidae (order Perciformes), found in the Nile and other rivers and lakes of Africa. A large-mouthed fish, the Nile perch is greenish or brownish above and silvery below and grows to about 1.8 m (6 feet) and 140 kg (300 pounds). It has an elongated body, a protruding lower jaw, a rounded tail, and two dorsal fins.

In 1954, L. niloticus was introduced into Lake Victoria in Africa, home to hundreds of cichlid fishes. A powerful predator, the Nile perch has greatly reduced the cichlid numbers.
