Uses: live export: yes;
Comments: Known from the Cubango/Okavango (Ref. 11970, 120641) and Zambezi (Ref. 120641). Reports from the southern Congo River basin (Ref. 120641) in the Cuilo (=Kwilu), Kasai, Luachimo and Chiumbe (Ref. 11970) are probably another species, because of the large heads and relatively few, broader than average body bars in these specimens (Ref. 26673). Rare in South Africa; threatened chiefly by water abstraction and pollution; weirs and dams obstruct its movement along rivers (Ref. 7248).

Africa: Zambezi, Okavango, Pungwe, Limpopo, and Buzi River systems southwards to the Pongolo River; absent in Kafue and Cunene Rivers (Ref. 7248, 52193). Also in the Luapula River system in Democratic Republic of the Congo and Zambia; records from southern tributaries of the Congo (Kasai, Luachimo, Chiumbe, Kwilu) may represent an other, unidentified species (Ref. 26673).

Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 11-13; Anale stekels 0; Anale zachte stralen: 13 - 17. Diagnosis: With striking vertical bars, lateral line curving down towards the ventral surface of the body and a large curved mouth (Ref. 13337).The dorsal fin is rounded; barbels absent (Ref. 13337).

Prefers clear, flowing waters of larger perennial rivers, frequenting pools below rocky rapids (Ref. 2801). Found also in quiet water with aquatic wed cover. Lives in shoals, usually in shallow water over sandy bottoms. It feeds on aquatic larvae and insects, shrimps and small crustaceans, from surface or water column (Ref. 13337, 52193). Breeds in spring and summer (Ref. 7248, 52193). Also caught with dip nets (Ref. 4967).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00575 (0.00288 - 0.01148), b=2.99 (2.82 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.48 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Prijsklasse (Ref. 80766): Unknown.
