B. bynni occidentalis: scale formula 5.5/26-31/4.5-5.5; 2.5-3 scales between lateral line and middle of belly, behind pelvic-fin origin; 12 scales around caudal peduncle; dorsal fin with 4 unbrached and 9 branched rays; anal fin with 3 unbranched and 5 branched rays; pectoral fin with 16-19 rays; pelvic fin with 1 unbranched and 8 branched rays; 3-5/12-15 gill rakers on first gill arch (Ref. 2940, 81282). B. bynni waldroni: scale formula 4.5/24-28/4.5; 2.5 scales between lateral line and middle of belly, behind pelvic-fin origin; 12 scales around caudal peduncle; dorsal fin with 4 unbranched and 9-10 branched rays; anal fin with 3 unbranched and 5 branched rays; pectoral fin with 1 unbranched and 14-16 soft rays; pelvic fin with 1 unbranched and 8 branched rays; 3-6/14-17 gill rakers on first gill arch (Ref. 2940, 81282).

Feed on crustaceans, insects, molluscs and organic debris; in the Jebel Aulia Reservoir, annual spawning coincides with the onset of the floods; fecundity estimates ranged from 72 x 1,000 at 33 cm (4 yrs.) to over 14 x 10,000 at 74 cm (8 yrs) (Ref. 28714).

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=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.40 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.26).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
