Scientific Name:	Barbus oligogrammus
Species Authority:	David, 1937
Taxonomic Notes:	The genus Barbus (Cyprinidae) is restricted to a small number of species mainly inhabiting the European ichthyographic region including Northeast Africa. Most of the African species which are currently included in the genus, taxonomically do not appear to be closely related to the genus Barbus sensu strictu. However, no attempts have yet been made at an adequate nomenclature of the African forms. We therefore follow Berrebi et al. (1996) and use in this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).

Assessment Information [top]

Justification: This species has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. It has also been assessed regionally as Least Concern for central and eastern Africa.
History:	2006 – Least Concern (IUCN 2006)

Geographic Range [top]

Range Description:	This species is distributed in Lake Tanganyika and surrounding rivers, in Tanzania, Zambia, Democratic Republic of Congo and Burundi. Central Africa: Barbus oligogrammus is known from Lake Tanganyika and affluents, the Ruzizi, the Lualaba and the Lukuga system. Eastern Africa:This species is present in affluent streams and rivers to Lake Tanganyika, incuding the Malagarasi river and Lake Rukwa system (Seegers 1996). Its distribution also includes Burundi.

Population [top]

Population:	No information available.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This is a benthopelagic species found in fast-flowing streams and rivers habitats. In the Lake Rukwa drainage it seems to prefer the smaller rivers and creeks with clear flowing water (Seegers 1996). It feeds on invertebrates, mostly insects.
Systems:	Freshwater

Threats [top]

Major Threat(s):

No information on major threats is known. Water turbidity due to erosion on watershed and agriculture extension may cause localised problems in eastern Africa.

Conservation Actions [top]

Conservation Actions:

No information available. Research should be conducted into population trends, and habitat maintenance in localised areas may be required.
