Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: Widespread throughout the Ethiopian Region of Africa, occurring commonly in all major river basins including the Nile, Chad, Senegal, Volta and Congo. Present in the brackish waters of Lake Mariout, near Alexandria. Exists in Lakes Albert, Rudolph and Tana. Several countries report adverse ecological impact after introduction.

Biology     Glossary (e.g. epibenthic)

Inhabits channels, lakes and irrigation canals. Adults inhabit deep water, while juveniles are found in shallow water. Feeds on fish especially clupeids and Alestes (Ref. 13851); smaller fish also feed on larger crustaceans and insects. Juveniles are planktivorous (Ref. 28714). Threatened due to over harvesting (Ref. 58490). No length type given but assumed to be in TL.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5006   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00769 - 0.01186), b=3.04 (2.98 - 3.10), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.19; tm=2-3).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
Price category (Ref. 80766):   Unknown.
