Tilapia guinasana
Naturally occurs in a single location (Lake Guineas). Benign introductions have been made into Lake Otjikoto and other farm dams but these have no formal protection. Two major threats are ground water extraction and the introduction of alien fishes (primarily tilapiine cichlids). Impacts of tilapiines range from competition for food and space, predation to introgression. This species is assessed as Critically Endangered under criterion B as it has a highly restricted AOO <1 km² (the lake is only 50 m in diameter), is limited to a single location, and is threatened by ongoing groundwater extraction and the potential introduction of an alien species.
