Habitat and Ecology [top]

Habitat and Ecology:

Barbus afrovernayi is a benthopelagic species. It is common in a variety of habitats, including the main Zambezi River channel, swamps, lagoons, pools scoured out below road culverts, and in small tributaries distant from the floodplain. It occurs in quiet, well-vegetated waters where it feeds from the surface or on small invertebrates living on plant surfaces (Skelton 1993, 2001). Barbus afrovernayi requires well oxygenated waters and is usually not found in small or headwater streams (Bell-cross and Minshull 1988). Rarer in northern Upper Zambezi tributaries (Tweddle et al. 2004).

Systems:

Freshwater

Threats [top]

Major Threat(s):

Although there are threats of overfishing in the Luapula-Mweru system and mining activities in the Katanga region, given the wide distribution and extensive suitable habitat in the Zambezi floodplains, there are no major threats to this species.

Conservation Actions:

None known.
