Estimates based on models

Preferred temperature (Ref. 123201): -1.6 - 5.8, mean 0.1 °C (based on 981 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00441 - 0.01037), b=3.12 (2.99 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.2 se; based on diet studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tmax=11; k=0.21).

Prior r = 0.82, 95% CL = 0.54 - 1.23, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
