- Die Oreochromini sind eine Tribus der Buntbarsche (Cichlidae), zu der zehn Gattungen gezählt werden, die bisher den Tilapiini zugerechnet wurden. Oreochromini-Arten sind in Afrika südlich der Sahara weit verbreitet und leben in Süß- und Brackwasser. Das Verbreitungsgebiet in Afrika reicht vom Senegal bis zum Kongo und den Flüssen Angolas und reicht über den Tschadsee bis in den Sudan, in den Nil und die ostafrikanischen Seen. Reliktpopulationen gibt es im marokkanischen Wadi Draa, in der Danakilsenke, im Jordan und im südlichen Iran. Es sind teilweise recht große Fische, die beliebte Speisefische sind und in Teichen gezüchtet werden. Wegen ihrer wirtschaftlichen Bedeutung sind viele Arten in anderen Ländern mit wärmerem Klima ausgesetzt worden. (de)
- Oreochromini is a tribe of cichlids in the Pseudocrenilabrinae subfamily that is native to Africa and Western Asia, but a few species have been widely introduced to other parts of the world. It was formerly considered to be part of the tribe Tilapini but more recent workers have found that the Tilapini sensu lato is paraphyletic. Despite this change, species in Oreochromini are still referred to by the common name tilapia and some of the most important tilapia in aquaculture —certain species of Oreochromis and Sarotherodon— are part of this tribe. In contrast, several species have small ranges and are seriously threatened; a few are already extinct (Tristramella sacra) or possibly extinct ( and O. lidole). Cichlids in the tribe Oreochromini are mouthbrooders, carrying the eggs and fry in their mouths instead of placing them in a nest. The numerous Oreochromis species are maternal mouthbrooders, meaning only the female looks after the eggs and fry, with the male offering no protection or help at all. Instead, they form leks where they compete with one another for further opportunities to mate with females. By contrast, most of the fewer Sarotherodon species are biparental mouthbrooders, with both parents protecting the eggs and fry. A few, such as S. melanotheron, are paternal mouthbrooders, with only the male caring for the eggs and fry. In addition, some species usually placed in Oreochromis might belong into Sarotherodon. Either this is incorrect due to hybridization effects, or they are not maternal mouthbrooders, or the diversity of brood care is even higher among these cichlids than hitherto believed. (en)
