Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 72 - 78; Anal spines: 0; Anal soft rays: 57 - 65; Vertebrae: 42 - 46. Dorsal origin over anterior part of upper eye. Caudal rounded. Pectorals small and narrow.

Occurs in the vicinity of rocky areas (Ref. 4925). Good food fish but is of little commercial importance due to its small size (Ref. 6885).

Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 9.6, mean 6.2 °C (based on 167 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00517 - 0.02552), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.3 se; based on diet studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tmax=20; tm=4).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).

Price category (Ref. 80766): Medium.
