Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 9 - 16; Vertebrae: 55 - 58. Body elongate, distinctly compressed laterally, and thin, greatest body depth in front of dorsal fin. Head about 23 - 26% of total length; eye large, but shorter than snout; snout always longer than eye diameter; mouth terminal, lower jaw usually projecting beyond the upper, usually with a distinct symphyseal knob or projecting posteriorly to below the anterior half of the eye. Overall coloration silvery with pink or purple iridescence, dark on back, silvery on sides, white below; often dark on tip of lower jaw, top of head, back and on dorsal and caudal fins. Pelvic fins usually immaculate.

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=0.00589 (0.00340 - 0.01021), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.51; tmax=10).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100).
Nutrients (Ref. 124155):  Calcium = 26 [12, 54] mg/100g; Iron = 0.586 [0.296, 1.249] mg/100g; Protein = 19.1 [17.8, 20.3] %; Omega3 = 2.57 [0.84, 9.13] g/100g; Selenium = 17 [6, 57] μg/100g; VitaminA = 15.8 [4.6, 54.6] μg/100g; Zinc = 0.721 [0.498, 1.047] mg/100g (wet weight);
