Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 31 - 33; Anal soft rays: 27 - 28. This species is distinguished by the following set of characters: body covered with ctenoid scales; two lateral lines with about 10 tubular scales; posterodorsal end of the opercle with a small hook; branchiostegal rays 6; conical teeth small; gill rakers well-developed (Ref. 131869).

Spawning may take place during middle to late summer.

Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - 0.8, mean -0.8 °C (based on 568 cells).

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

Bayesian length-weight: a=0.00229 (0.00120 - 0.00437), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 200).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
