Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Anal soft rays: 192 - 22. Snout moderate, about 1/2 eye or a little more; maxilla moderate, tip not sharply pointed, not or only just reaching hind border of pre-operculum; gill cover canals of walkeri-type. Anal fairly short, its origin under about midpoint of dorsal fin base. Anus nearer to pelvic fin tips than to anal fin origin. Silver stripe along flank, about 1/2 eye diameter or a little more.

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=0.00832 (0.00486 - 0.01423), b=3.13 (2.99 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.24 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
