Africa: Lake Malawi (Ref. 2, 5166, 118630). Reports from Lake Chungruru (Ref. 2, 54852) and Lake Kingiri (Ref. 2, 54852) are misidentifications of Oreochromis chungruruensis and juvenile Oreochromis squamipinnis respectively (Ref. 118638).

Diagnosis: breeding male black; length of head 34.4-42.4% SL; length of lower jaw 31.3-40.0% head length (Ref. 2). Teeth of jaw in 3-4, rarely 5 rows (Ref. 2,6150). Lower pharyngeal bone with restricted toothed area; median length of bone 33.0-40.7 % length of head and 1.3-1.5 times its own width; blade 1.9-3.9 times median length of toothed area (Ref. 2).

Biología     Glosario (por ej. epibenthic)

Occurs in all kinds of habitats but is mainly found in open water away from the coast (Ref. 5595). The most pelagic of the Lake Malawi Oreochromis species (Ref. 2, 87, 4364, 4916, 4967). Forms schools (Ref. 2, 2781). Feeds on phytoplankton (Ref. 2, 87, 5595, 10402, 42295, 52161). Female mouthbrooder (Ref. 2). It is suspected that Oreochromis lidole is now globally extinct, as it has not been positively recorded since 2007 (Ref. 118638).

Ciclo vital y comportamiento de apareamiento Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Seems to be sexually mature at a smaller size in Lakes Chungruru and Kingiri than in Lake Malawi (Ref. 2, 54852). Spawns off clean sandy or rocky shores (Ref. 2, 87, 2781) in deeper water (Ref. 2, 87, 2781, 5595, 6150, 40193). Territorial males build a large (Ref. 5595, 40193, 55079) sand-castle nest, with a characteristic spawning cone in its center (Ref. 2, 5595). Females congregate in schools that may number hundreds of individuals (Ref. 2, 2781, 5595). The male genital tassel, which develops together with the breeding dress and imitates a clutch of eggs, is dragged through the nest after the females has deposited some eggs, which are picked up immediately; the female probably mistakes the tassel for eggs that have been forgotten and tries to collect them as well, which results in the eggs being fertilized (Ref. 5595). Females carrying eggs in the mouth move into open, more eutrophic waters, and stay there until the young have almost lost the yolk sac; they feed little during this time (Ref. 2781). Females brood eggs/young, guarding their fry until about 52(-58)mm (Ref. 2, 2781). Females move inshore with their young for at least part of the day; the young are spat out to feed, and food (small phytoplankton) is found in the foregut before the involuted yolk-sac is fully absorbed (Ref. 2781).
