Nile perch 
noun
A large predatory fish found in lakes and rivers in NE and central Africa, widely caught for food or sport.
- Lates niloticus, family Centropomidae.
- When Nile perch began to impact local cichlid fisheries, locals started to consume Nile perch, but this fish required firewood for drying and preservation because it is much larger.
- The most common place to find the Nile perch is in Lake Victoria where the species was introduced in 1962.
