Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA ACTINOPTERYGII CYPRINIFORMES CYPRINIDAE

Scientific Name: Barbus nyanzae
Species Authority: Whithead, 1960
Common Name/s:
English – Nyanza Barb
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this paper the term ‘Barbus’ for the cyprinid fish species which were previously considered as Barbus (Seegers et al., unpublished).

Population [top]

Population: Unknown, but rare.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Found both in streams, rivers and lake. Fishes migrate upstream to spawn. The principal spawning grounds appear to be the floodwater pools. Half-grown fishes migrate into the river and down to the lake at the next flood (Whitehead 1960). Feed predominantly on insect larvae. Max. size: 7.0 cm SL (after Froese and Pauly 2003).
Systems: Freshwater

Threats [top]

Major Threat(s): Water turbidity due to erosion on watershed and agriculture extension.

Conservation Actions [top]

Conservation Actions: No information available.
