Assessment Information [top]

Red List Category & Criteria:	Least Concern     ver 3.1
Year Published:	2010
Assessor/s:	da Costa, L. & Moelants, T.
Reviewer/s:	Snoeks, J., Tweddle, D., Getahun, A., Lalèyè, P., Paugy, D., Zaiss, R., Fishar, M.R.A & Brooks, E.
Justification: This species has a wide distribution, with no known major widespread threats. It is therefore listed as Least Concern. For southern Africa, it is known from two catchments: Kwanza and Kunene River. No obvious threats are known. Larger distribution is expected and therefore it has been categorised as Least Concern. More comprehensive surveys required to confirm the true extent of its distribution. For central Africa, the Congo populations may represent another species, and therefore it has been assessed as Data Deficient.
History:	2007 – Least Concern

Habitat and Ecology [top]

Habitat and Ecology:

Barbus mattozi is a benthopelagic, potamodromous species. Naturally it is occurring in large pools of cooler perennial rivers, it also thrives in man-made impoundments. It is an active predator which feeds initially on small planktonic crustaceans and insects; later it feeds on small fishes. It also feeds on water lily seeds. Barbus mattozi is preyed upon by birds, otters, large catfish and large papermouths. It migrates upstream with the first summer flood to spawn. Barbus mattozi matures after three years (Skelton 1993).

Systems:

Freshwater

Threats [top]

Major Threat(s):

In the Katanga region, mining for cobalt, copper, tin, uranium, dams and the use of toxic plants for fishing and overfishing form threats in this region. Further threats are unknown.

Conservation Actions [top]

Conservation Actions:

No information available. More research is needed into this species population numbers and range, biology and ecology, habitat status and threats, as well as monitoring of the populations.
