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. |
|
| Range Description: | The species is distributed in Lake Rukwa and its tributaries, Lake Tanganyika and the Malagarasi. |
| Countries: |
Native:
Burundi; Tanzania, United Republic of
|
| 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: | 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 |
| 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: | None known. |
