Africa: Luapula, Lake Bangwelu and surrounding swamps, and the Chambezi (upper Congo River basin) in Democratic Republic of the Congo and Zambia (Ref. 246, 45616, 52346). Reports from the Luvua, upper Lualaba and lakes Mweru and Upemba (Ref. 2970, 45616) based on misidentifications (Ref. 52346).

Maturity: L_m 11.5, range 11 - 12 cm
Max length : 27.5 cm TL macho/indeterminado; (Ref. 52962)

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 13 - 15; Raios dorsais (total) : 14 - 16; Espinhos anais: 3; Raios anais : 7 - 8; Vértebras: 28. Diagnosis: lower lateral line extending far forward (Ref. 52962).

Predominant food is the lake-fly in its larval aquatic stages (Ref. 246). Also feeds on plants; maternal mouthbrooder that does not pair-bond (Ref. 52307). Max. length of 27.5 cm presumed to be TL.

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Female mouth-brooder; breeding occurs during the rainy seasons and the young, a favorite prey for the tiger-fish, keep closer inshore among Eleocharis reed and other vegetation (Ref. 246). Young fish still attached to the yolk sac can be found in the mouth of a parent which is at the verge of spawning again (Ref. 52961). The species breeds during a single spawning period toward the end of the rainy season (Ref. 2774). At highwater, the fish move from the lake to their breeding grounds in adjacent swamps to spawn (Ref. 52346).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00986 - 0.03683), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (tm=2-3; K=0.4).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100).
