Biology     Glossary (e.g. epibenthic)

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. 123201): 23.5 - 28.6, mean 27.5 °C (based on 707 cells).
Phylogenetic diversity index (Ref. 82804):  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   ±0.57 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 data-limited stock assessments.
