Africa: native in Kasai River (middle Congo River basin) (Ref. 11970), upper Lualaba (Ref. 11970, 13337) and Mweru-Bangweulu area (Ref. 95585) (upper Congo River basin), Okavango delta (Ref. 27501), Caprivi Strip (Ref. 37065), Cunene River (Ref. 13332), Upper Zambezi and Middle Zambezi (Lake Kariba, Kafue and Luangwa systems) (Ref. 97235, 94654). Introduced into localities in Zimbabwe (Ref. 94654), into the Sabi River (Ref. 13721) and into Botswana, South Africa and Swaziland (Ref. 6465).

Biology     Glossary (e.g. epibenthic)

Lives in well-vegetated quiet waters or near submerged trees or rocks in the lee of the river’s main current, lunging out to capture prey (Ref. 5614). Juveniles occur mainly in lagoons and secondary channels (Ref. 7248, 94654), while adults prefer deep main channels and permanent lagoons (Ref. 7248). Large specimens patrol open water of rivers and lakes, never very far from shore (Ref. 246). Predator on fish but also feeds on aquatic and terrestrial insects, shrimps and small crabs (Ref. 13337). Adults often feed on squeakers (Ref. 7248, 13337, 94654). Mouthbrooder (Ref. 246, 13337, 13721) and multiple spawner (Ref. 13337). Constructs shallow nest on sandy or muddy substrate in shallow water (Ref. 13337). Reported to have adverse impact on native fish species in Zimbabwe (Ref. 94654).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Incubates eggs in the mouth. Constructs a shallow concave nest on a sandy or muddy substrate in fairly shallow water.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00900 - 0.03679), b=2.99 (2.83 - 3.15), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100) .
Price category (Ref. 80766):   Unknown.
