Taxonomic Notes: Taxonomic revision ongoing.  As presently recognised, this species has a very wide geographical range. It is perhaps a species complex with additional closely related species in central and east Africa. The taxonomic status of populations of this species in southern Africa needs to be determined. It is synonymised with L. kirkii Boulenger 1903 by Reid (1985) and Seegers (1996) but this assessment has followed Leveque and Daget (1984) and Tshibwabwa (1997) in considering these two populations distinct.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-05-01
Assessor(s): Bills, R., Cambray, J., Getahun, A., Hanssens, M., Marshall, B., Moelants, T. & Ntakimazi, G.
Reviewer(s): Snoeks, J., Tweddle, D., Getahun, A., Lalèyè, P., Paugy, D., Zaiss, R., Fishar, M.R.A & Brooks, E.
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, eastern, north eastern and southern Africa.

Geographic Range [top]

Range Description:Labeo cylindricus is widely distributed across the southern half of Africa, from the Democratic Republic of Congo and Ethiopia, to South Africa.

Central Africa: The distribution of this species in the Congo River Basin is limited to the Central and This species is known from upper regions (Tshibwabwa 1997).

Eastern Africa: It is widespread in east Africa, and is present in the Pangani drainage, Athi River system (including Tsavo drainage), Galana system, This species is known from upper Tana, Northern Ewaso Nyiro basin, Lake Baringo system, Lake Bogoria (affluents), Turkwell and Kerio system (Turkana drainage), Suguta drainage. It has also been found in Lake Tanganyika and Lake Malawi. It occurs as a rarity in Lake Turkana (Seegers et al. 2003). Also distributed in Lakes Malawi, Chuita and Chilwa Shire River, and the middle and lower Zambezi system. Boulenger (1903) reported this species from the Lumi River (Pangani drainage) as Labeo montanus (Günther, 1889), a junior synonym (Seegers et al. 2003).

Northeast Africa: This species is found in the Baro River and Rift lakes of Ethiopia.

Southern Africa: It is widespread in southern and eastern Africa from the Phongolo River in northern KwaZulu-Natal (Skelton 2001), South Africa, north into the Congo.
Countries occurrence:
Angola; Botswana; Burundi; Congo, The Democratic Republic of the; Ethiopia; Kenya; Malawi; Mozambique; Namibia; South Africa (Gauteng, KwaZulu-Natal, Limpopo Province, Mpumalanga); Swaziland; Tanzania, United Republic of; Zambia; Zimbabwe

Population [top]

Population:Little information was available on population status. Abundant in suitable rocky fast flowing habitats in southern Africa. It is, however, assumed to be in decline in eastern Africa due to the many threats identified. It is rare in the fisheries around Lake Tanganyika.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Labeo cylindricus is a benthopelagic and potamodromous species. It occurs in both sediment-free and sediment-rich rocky biotopes. Labeo cylindricus favours clear, running waters in rocky habitats of small and large rivers, also found in lakes and dams over rocky areas. Also found in lakes and dams over rocky areas. It feeds on diatoms and other small algae from the rocks (Konings 1990). Labeo cylindricus also feeds on `aufwuchs' from the surface of rocks, tree trunks and other firm surfaces. Labeo cylindricus swims upstream in masses to breed, using the mouth and broad pectorals to climb damp surfaces of barrier rocks and weirs (Skelton 1993). It is mainly caught when migrating up streams from the lake to spawn. Populations in Lake Malawi have a well marked breeding season in December. The breeding season is very short and the eggs are laid among the rocks. In Malawi it is reported that there are both permanent riverine populations and lacustrine populations.
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: Labeo cylindricus is used as an algae grazer in public aquariums. It is also harvested as a food fish.

Threats [top]

Major Threat(s): Labeo cylindricus is used as an algae grazer in public aquariums, as well as collected as a food source. Its habitat is being degraded by sedimentation from agricultural practices.

Conservation Actions [top]

Conservation Actions: None known. This species needs (and is undergoing) taxonomic revision. Population trends should be monitored, and policy-based action may be needed to control exploitation. Habitat maintenance may also be required.
