Also in the upper Zambezi and Okavango (Ref. 7248, 11970, 52193, 75786), Cunene, Limpopo (Ref. 3202, 11970, 75786, 82238) and Lake Chiuta (Ref. 75786). Absent from the Lake Tanganyika drainage (Ref. 78218).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 11 - 15.

Prefers rocks or marginal vegetation of flowing riverine channels to lagoons or backwaters (Ref. 7248, 52193). It feeds on a variety of food including detritus, algae and plant material, insects, snails and small fish, and scavenges readily (Ref. 7248, 52193). Eggs and larvae of cichlids have been reported in stomach of this species (Ref. 78218). Oviparous (Ref. 205). Breeds during the summer rainy season (Ref. 7248, 52193), with a peak coinciding with heavy rains in January to March (Ref. 13337). Juveniles move off the floodplains when water recedes (Ref. 13337). Grows to a large size (Ref. 246).

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=0.01479 (0.00841 - 0.02600), b=2.87 (2.72 - 3.02), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on diet studies.

Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.8).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Price category (Ref. 80766): Unknown.
