Short description Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 23-25; Anal spines: 0; Anal soft rays: 20 - 22. Head, body and fins of adults dark; body with elongated white spots that may disappear with growth (Ref. 4420).

Found in shallow coastal and offshore waters (Ref. 9276, 11230). Epipelagic nearly all throughout life, often associated with drifting objects (Ref. 1602, 44187). May occur on deep rocky slopes (Ref. 7251). Feeds on zooplanktons (Ref. 89972). Appear to school in large numbers based on catches from set nets (Ref. 637). Oviparous (Ref. 205). Marketed fresh (Ref. 9770).

Estimates based on models

Preferred temperature (Ref. 115969): 23 - 29, mean 27.7 (based on 2250 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02570 (0.01232 - 0.05364), b=2.94 (2.77 - 3.11), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Medium.
