Teleostei (teleosts) > Characiformes (Characins) > Alestidae (African tetras)
Etymology: Bryconaethiops: Greek, bryko = to bite+ Aethiops, region in North east Africa (Ref. 45335).
More on author: Günther.

Issue
The synonym Bryconaethiops yseuxi is revalidated (Ref. 74421).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; pelagic; pH range: 6.0 - 7.5; dH range: 8 - 18. Tropical; 24°C - 28°C (Ref. 2060)

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

Africa: Ogowe (Ref. 5331, 80290), Nyong, Lobé, Ntem, Kouilou basins and in Nkomi lagoon (Ref. 80290). Also in the lower, middle (Ref. 80290) and upper (Ref. 5331) Congo and the Malagarasi (Ref. 54847). Reports from Lake Kivu (Ref. 5331, 80290) are based on an erroneous locality interpretation whereby the Kivu Province was mistaken for Lake Kivu (Ref. 46152).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 18 - 23. Diagnosis: 6.5-7.5 scales in transverse row between lateral line and dorsal fin origin; 12 scales around caudal peduncle (Ref. 74421, 80290); 35-40 (Ref. 80290) or 34-41 (Ref. 74421) lateral line scales. Eye diameter/head length 26-40% (Ref. 80290) or 31.4-43.8 (Ref. 74421). 15-20 (Ref. 80290) or 17-19 (Ref. 74421) anal fin branched rays.

Biology     Glossary (e.g. epibenthic)

Affinities: similar to B. macrops but with a higher number of scales around caudal peduncle and a smaller eye (Ref. 80290).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00654 - 0.02211), b=3.02 (2.86 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
