Estimates based on models

Preferred temperature (Ref. 123201): 0.9 - 5.9, mean 3.9 °C (based on 236 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on diet studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (K=0.18; tmax=57).
Prior r = 0.06, 95% CL = 0.04 - 0.10, Based on 2 stock assessments.
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
