The IUCN Red List of Threatened Species

Barbus acuticeps

 – Endangered

Taxonomy

Kingdom: ANIMALIA
Phylum: CHORDATA
Class: ACTINOPTERYGII
Order: CYPRINIFORMES
Family: CYPRINIDAE
Scientific Name: Barbus acuticeps
Species Authority: Matthes, 1959
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 that 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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).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

Red List Category & Criteria: EN A2bcd    ver 3.1 (2001)
Year Assessed: 2006
Assessor/s: Ntakimazi, G.
Evaluator/s: Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification: Endemic to the upper and middle Akagera River where it is found in the main channel of rivers and sometimes in lakes. Very common some decades ago, it has since become rather rare. There is evidence for a >50% decline in population (Ntakimazi 1985). Fisheries pressure, wetlands regression and increased water turbidity due to erosion on watershed are the main threats for this species (Ntakimazi 1985).
