Actinopterygii (ray-finned fishes) > Characiformes
(Characins) > Alestidae
Etymology: Bryconaethiops: Greek, bryko = to bite+ Aethiops, region in North east Africa (Ref. 45335). More on author: Pellegrin.
Environment / Climate / Range
Freshwater; pelagic. Tropical; 22°C - 27°C (Ref. 13614)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 13614); common length : 14.0 cm SL male/unsexed; (Ref. 4967)
Africa: Congo River basin in Republic of Congo and Democratic Republic of the Congo (Ref. 74421). Type locality in Ogowe is questionable as no other specimens are known from Ogowe drainage (Ref. 74421). Report from Lake Tanganyika (Ref. 4967) needs confirmation.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00517 - 0.02552), b=3.00 (2.81 - 3.19), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
