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

Africa: Nile, from the Delta to Bahr-el-Jebel, Niger and Chad basins. Also in the Bénoué River (Ref. 2915). Affinities: close to Marcusenius abadii. # of anal fin rays, # of scales on lateral line and the position of the dorsal and anal fins distinguishes one from the other.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 33.0 cm SL male/unsexed; (Ref. 2915); max. published weight: 458.00 g (Ref. 2915)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 25-31; Anal spines: 0; Anal soft rays: 31 - 37. Dorsal fin slightly behind anal fin origin. Body depth 3.0-4.7 x SL and peduncle length 2.0-3.4 x its depth.

Inhabits lakes. Bottom feeding insectivore. Breeds during flood season and enters the floodplain for this purpose (Ref. 28714). Shows three 'preferred' modes of intervals between electric organ discharges (inter-EOD) when at rest: 10-35 ms, 50-120 ms and 200-350 ms (Ref. 10833).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00650 - 0.02027), b=2.85 (2.70 - 3.00), in cm total length, based on LWR estimates for species & Genus-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.37 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100) .

Climate Vulnerability (Ref. 125649): (0 of 100) .

Price category (Ref. 80766): Unknown.
