Scientific Name: Labeo fuelleborni
Species Authority: Hilgendorf & Pappenheim, 1903
Common Name/s:
English Fuelleborn's Labeo

Assessment Information [top]

Red List Category & Criteria: Data Deficient     ver 3.1
Year Assessed: 2006
Assessor/s: Bayona, J.D.R. & Hanssens, M.
Reviewer/s: Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification:
The sub-population in Lake Tanganyika (Tanzania) has declined by greater than 50% within the last 20 years based on fishing catch data, loss of spawning habitat and increased fishing pressure. This indicates the population may be threatened, but there are no data on population trends in the Malagarasi or Lake Rukwa drainages where this species is also found. The lack of information for these other parts of the population result in a Data Deficient status for this species.

Population [top]

Population: The species is being exploited commercially. Catch compositions in Lake Tanganyika were 11.89% in 1977 (Bernascek 1980) declining significantly to 1.24% in 1996 (Fish. Div. 1996). The index of abundance declined from 1.3 tons/vessel in 1977 to 0.1 tons/vessel in 1996. The decline is close to 90% over a 20 yr period.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: A deep water species. It migrates upstream to spawn during the rainy season (Eccles 1992). In the rivers it is found in deep waters and rapids where it grazes algae on firm surfaces.
Systems: Freshwater

Threats [top]

Major Threat(s): Spawning substrate and habitats are being degraded due to silting and pollution (water turbidity due to erosion on river basins). Illegal fishing methods with small meshed nets, especially across rivers during the spawning migration.

Conservation Actions [top]

Conservation Actions: None known.
