Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 8.8, mean 4.7 °C (based on 1094 cells).

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

Bayesian length-weight: a=0.00794 (0.00691 - 0.00913), b=3.08 (3.04 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.2 se; based on diet studies.

Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tm=7; K=0.25).

Prior r = 0.31, 95% CL = 0.20 - 0.46, Based on 4 full stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
