Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 18-20; Anal spines: 3; Anal soft rays: 16 - 17.

Adults are primarily oceanic, pelagic schooling species rarely seen on reefs (Ref. 48635, 90102). They feed mainly on fishes (Ref. 5213). Generally marketed fresh (Ref. 5284).

Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 28.6, mean 27.5 °C (based on 707 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01288 (0.01159 - 0.01432), b=2.93 (2.90 - 2.96), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.64 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13(?)-0.35; Fec=146,400).

Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 20 stock assessments.

Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100) .

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 132 [25, 547] mg/100g ; Iron = 2.16 [0.59, 5.69] mg/100g ; Protein = 19.4 [17.7, 20.9] % ; Omega3 = 0.408 [0.146, 1.134] g/100g ; Selenium = 74.7 [20.9, 266.5] μg/100g ; VitaminA = 21 [4, 141] μg/100g ; Zinc = 0.655 [0.174, 2.329] mg/100g (wet weight); based on nutrient studies.
