Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 12 - 13; Anal spines: 1; Anal soft rays: 9 - 10; Vertebrae: 27 - 29. This species is distinguished by the following characters: spinulated (without gap) posterior and lower edges of praeoperculum; insertion of ventral fins behind the vertical of posterior edge of pectoral fin insertion; upper jaw extends beyond the vertical of posterior eye edge; soft rays in dorsal fin 12-13, in anal fin 9-10; rakers at first gill arch 28-30; vertebrae 27-29; pyloric caeca 6 (Ref. 83717).

Oviparous, with planktonic eggs and larvae (Ref. 36655). There is significant morphological variation between populations (Ref. 4241).

Estimates based on models

Preferred temperature (Ref. 115969): 1.7 - 6.3, mean 3.2 (based on 2535 cells).

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

Bayesian length-weight: a=0.00912 (0.00403 - 0.02064), b=3.09 (2.89 - 3.29), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=8.5).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
