Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1 - 2; Dorsal soft rays (total): 31 - 34; Anal spines: 0; Anal soft rays: 27 - 31; Vertebrae: 19.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00956 - 0.04164), b=2.93 (2.76 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 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 (10 of 100).
Nutrients (Ref. 124155):  Calcium = 63.4 [26.0, 158.7] mg/100g; Iron = 0.758 [0.360, 1.824] mg/100g; Protein = 17.8 [15.6, 20.1] %; Omega3 = 0.126 [0.058, 0.264] g/100g; Selenium = 41.1 [19.1, 94.3] μg/100g; VitaminA = 63.7 [16.6, 248.5] μg/100g; Zinc = 1.44 [0.93, 2.30] mg/100g (wet weight);
