Nile tilapia
The Nile tilapia (''Oreochromis niloticus'') is a species of tilapia, a cichlid fish native to Africa from Egypt south to East and Central Africa, and as far west as Gambia. It is also native to Israel, and numerous introduced populations exist outside its natural range (e.g. Brazil). It is also commercially known as mango fish, ''nilotica'', or ''boulti''.〔(''Nile Tilapia'' ). Seafood Portal.〕 The first name leads to easy confusion with another tilapia traded commercially, the mango tilapia (''Sarotherodon galilaeus'').
==Description==
The Nile tilapia has distinctive, regular, vertical stripes extending as far down the body as the bottom edge of the caudal fin, with variable coloration. Adults reach up to in length and up to . It lives for up to 9 years. It tolerates brackish water and survives temperatures between . It is an omnivore, feeding on plankton as well as on higher plants. Introduced tilapia can easily become an invasive species (see Tilapia as exotic species). It is a species of high economic value and is widely introduced outside its natural range; probably next to the Mozambique tilapia (''O. mossambicus''), it is the most commonly cultured cichlid. In recent research done in Kenya, this fish has been shown to feed on mosquito larvae, making it a possible tool in the fight against malaria in Africa.〔("Nile tilapia can fight malaria mosquitoes" ), BBC News, 8 August 2007.〕
