Short description
Biology
Adults are found in the sublittoral zone and may enter semi-enclosed sea areas (Ref. 11230). In Guam, it is encountered in large numbers around fish aggregating devices, buoys anchored offshore to attract pelagic game fishes.

Estimates based on models
Preferred temperature (Ref. 123201): 22.7 - 29, mean 28 °C (based on 892 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.501 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.01046 - 0.01447), b=2.97 (2.94 - 3.00), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.4 ±0.5 se; Based on food items.
Generation time: 1.2 (1.0 - 1.4) years. Estimated as median ln(3)/K based on 24 growth studies.
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.5-1.3; tmax=9).
Fishing vulnerability (Ref. 59153): Low vulnerability (23 of 100).
Climate vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).
Price category (Ref. 80766): Very high; Reliable: based on ex-vessel price for this species.
Nutrients (Ref. 124155): Calcium = 300 [102, 710] mg/100g; Iron = 3.11 [1.18, 6.59] mg/100g; Protein = 20.4 [19.1, 21.7] %; Omega3 = 0.234 [0.122, 0.435] g/100g; Selenium = 84.3 [30.9, 199.6] μg/100g; VitaminA = 41.6 [13.6, 143.1] μg/100g; Zinc = 1.4 [0.8, 2.2] mg/100g (wet weight);
