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

Africa: from the lower Congo River just below Pool Malebo (=Stanley Pool) throughout the middle Congo River basin up to the Wagenia Falls, including Pool Malebo, middle Congo River, the Kasai drainage, lakes Mai-Ndombe and Tumba, the Ruki, Sangha and Aruwimi (Ref. 52346). Also in the Aruwimi and Lindi-Tshopo (Ref. 106290). Also reported from the Ubangi (Ref. 45441) but this drainage is explicitly excluded from the species' distribution area in Ref. 52346.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13 - 16; Dorsal soft rays (total): 12 - 15; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 28 - 30. Diagnosis: 35 or fewer lateral line scales; 17 gill-rakers along lower limb of first arch; inferior vertebral apophysis with characteristic spade-like outline; lower pharyngeal jaw never very robust or mill-like; molariform dentition rarely covers half of the dentigerous surface; posstempral latero-sensory canal not fully ossified and trough-like; pectoral fins long, usually reaching the anal fin (Ref. 52346).

Biology     Glossary (e.g. epibenthic)

Benthic macrophage (Ref. 52346). Feeds mainly upon insect larvae, plants and fruits, as well as detritus and molluscs (Ref. 52307, 52346). Maternal (Ref. 52307) mouth brooder (Ref. 51193) that does not pair bond (Ref. 52307). Tastes like Nile perch, Lates niloticus (Ref. 51906).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02042 (0.01042 - 0.04000), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.48 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
