The Nile perch (Lates niloticus) is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of Ethiopia. Lates niloticus is silver in colour with a blue tinge. It has a distinctive dark-black eye, with a bright-yellow outer ring. One of the largest freshwater fish, it reaches a maximum length of nearly 2 m (more than 6 ft), weighing up to 200 kg (440 lb). Mature fish average 121–137 cm (48–54 in), although many fish are caught before they can grow this large. It is fairly hard to get outside of Ethiopia and other countries of residence, but if you can it is extremely tasty and worth a little search. Tilapia is a good alternative.
