Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 13 - 14; Rayons mous dorsaux (Total): 13-16; Épines anales 3; Rayons mous anaux: 7 - 9; Vertèbres: 26. Head spines weak to very weak - nasals present, preocular and postocular spines usually absent, supraocular, tympanic, coronal, parietal and nuchal spines absent (Ref. 27437). Symphyseal knob very weak or absent (Ref. 27437). Eyes moderately large (Ref. 27437). Anal fin profile rounded or with greater portion slanted posteriorly (Ref. 27437). Posterior margin of caudal fin indented (Ref. 27437). Dark grey to black with light grey mottling dorsally, lighter ventrally (Ref. 27437). Branchiostegal rays: 7 (Ref. 36715).

Found near rocky reefs in shallow water and in open water over deep banks (Ref. 2850). Adults live both off and on bottom (Ref. 2850). Juveniles are pelagic (Ref. 36715). Form schools (Ref. 2850). Feed on fishes (Ref. 27302). Viviparous, with planktonic larvae (Ref. 36715). Young are important prey species for other fishes, marine mammals and birds. Excellent food fish (Ref. 27436).

Estimates based on models

Preferred temperature (Ref. 123201): 3.8 - 7.8, mean 5.5 °C (based on 52 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.4 ±0.0 se; based on diet studies.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (tm=7.5; K=0.14; tmax=50).

Fishing Vulnerability (Ref. 59153): High vulnerability (64 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (37 of 100).

Catégorie de prix (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 6.07 [2.24, 17.66] mg/100g; Iron = 0.114 [0.045, 0.266] mg/100g; Protein = 18.9 [17.8, 20.2] %; Omega3 = 0.774 [0.291, 2.159] g/100g; Selenium = 25.3 [9.1, 74.1] μg/100g; VitaminA = 96.4 [29.4, 326.0] μg/100g; Zinc = 0.322 [0.164, 0.589] mg/100g (wet weight); based on nutrient studies.
