Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Taxonomic Remarks
Turner and Robinson 1991 (Ref. 55079) conclude that Oreochromis saka is a junior synonym of O. karongae (also Ref. 6150), although Turner et al. 1989 (Ref. 40180) reported O. squamipinnis to be most similar to O. saka and O. karongae the most divergent (also Ref. 55954).
