Issue
Three subspecies were described on the basis of different morphological characters: tchadense Blache, 1964, soudanensis and eburneensis Paugy, 1986. However they should rather be considered as populations having equivalent ecological characteristics (D. Paugy, pers,comm 21 Mar. 2013).
Environment: milieu / climate zone / depth range / distribution range Ecology
Freshwater; benthopelagic; pH range: 6.5 - 7.8; dH range: ? - 30; potamodromous (Ref. 51243). Tropical; 15°C - 35°C

Africa: Senegal, Gambia, the coastal basins of the Côte d'Ivoire (Comoé, Bandama and Sassandra), Volta, Niger/Benué and Chad basin (Ref. 2880, 81279). Also present in Nile, Omo, Lake Albert and Lake Turkana (Ref. 2880, 28714). Three populations - previously as subspecies - may be distinguished by slight morphological differences but they have the same ecological charasterics: in Nile River, Lake Albert, Omo River and Lake Turkana ('baremoze'); in Senegal River, Gambia River, Tominé River, Volta basin, Niger basin and Chad basin ('soudaniensis'); in coastal basins of Côte d'Ivoire, namely Sassandra River, Bandama River and Comoé River ('eburneensis') (Ref. 42019).

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 22 - 31; Vertebrae: 41 - 49. Diagnosis: at least 30 gill rakers on lower limb of first gill arch (30-41); 38-51 lateral line scales, with 7.5-9.5 above and 3.5 below; anal fin with three simple rays and 19-28 branched rays; dorsal-fin origin distinctly behind level of pelvic-fin insertions (Ref. 2759, 81279).
Mainly diurnal. There is considerable flexibility in its diet, A. baremoze shifts from zooplankton to zoobenthos, detritus and macrophytes as plankton densities decline (Ref. 28714). Occurs at a temperature range of 14.6-35.0°C. In the Malamfatori area (Tchad), seine-net fishery on the River Yobe depends on seasonal upstream (from Lake Chad) and downstream migration during the flood (August-December) and dry (January-March) seasons, respectively. Also, there is an intensive gillnet fishery from July-October at the river mouth. A. baremoze moves offshore (in Lake Chad) beginning March.
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Spawning cycle from Tables XVI-XVIII of Ref. 2759 for maturity stages 3-4 GSI 1.5-16% from deltaic zone, upstream (Logone-Chari River), downstream (N'Djamena) and in the southeastern archipelago of Lake Chad. Spawning takes place from 16:30-20:00 h. Eggs spawned in one batch representing 15% of weight of female. Mature females dispersed, not forming groups.

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00833 - 0.01316), b=3.02 (2.96 - 3.08), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.1 ±0.35 se; based on food items.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.42; tm=2-3; tmax=6).
Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
