Sarotherodon steinbachi
Overview
The kululu (Sarotherodon steinbachi) e.g. Vikululu - Nikululu - Akululu - Bokululu - Hekululu is a species of cichlid endemic to Lake Barombi Mbo in western Cameroon. This species can reach a length of 11.3 centimetres (4.4 in) SL.
It is threatened because of pollution and sedimentation due to human activities. It is potentially also threatened by large emissions of carbon dioxide (CO2) from the lake's bottom (compare Lake Nyos), although studies indicate that Barombo Mbo lacks excess amounts of this gas.
Sarotherodon steinbachi faces severe population decline primarily due to habitat degradation and water pollution in its limited freshwater range. The species is particularly vulnerable to agricultural runoff and industrial contamination that affects water quality in its native river systems. Competition and hybridization with introduced tilapia species has further reduced pure breeding populations, while dam construction has fragmented remaining suitable habitat.
Habitat
This cichlid fish inhabits freshwater rivers and associated wetland systems in West Africa. The species requires clean, well-oxygenated waters with specific temperature and pH ranges typical of tropical African river ecosystems.
