Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 20 - 21. Anal fin margin of females straight or very slightly concave; markedly convex in males (individual rays are stouter and coarser than those of females). Silver, bluish to black dorsally; silver longitudinal band running from behind the operculum to the caudal peduncle, where it merges with an irregular black blotch which extends to the caudal fin base. All fins grey in color; other specimens all yellowish (except for pectorals). Dorsal adipose fin bright orange (Ref. 34290).

Estimates of some properties based on empirical models

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

Bayesian length-weight: a=0.01220 (-0.16758 - 0.19197), b=3.00 (2.91 - 3.09), based on LWR estimates for this genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.40 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (K=4.6).

Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100) .

Price category (Ref. 80766): Unknown.
