Geographic Range [top]

Range Description:This species is wide ranging from Democratic Republic of Congo to South Africa.

Central Africa: Barbus unitaenatus is thought to be present in the upper Congo River basin upstream of the Lukuga system. Specimens recently collected from the Inkisi River (AMNH) have tentatively been identified as this species but these need confirmation.

Southern Africa: It is widely distributed in southern Africa from the Zambian Congo and the Cunene, Okavango and This species is known from upper and middle Zambezi south to the Phongolo (Skelton 2001). Absent from the Lower Zambezi, but present in the Pungwe and Buzi Rivers.

Habitat and Ecology [top]

Habitat and Ecology:Barbus unitaenatus is a benthopelagic species. It is mainly restricted to areas of medium to strong flow over sandy bottoms in the main river channels, including sandy back eddies bordering rapids. It does not normally occur in vegetated streams or still-water lagoons (Tweddle et al. 2004), but it does occur in open dams and lakes (Skelton 2001). Barbus unitaenatus feeds on aquatic invertebrates and grass seeds. It breeds after rains during summer months (Skelton 1993, 2001).

Use and Trade [top]

Use and Trade: This species is harvested for human consumption.
