Estimates based on models

Preferred temperature (Ref. 123201): 0.4 - 5.9, mean 2.8 °C (based on 418 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00384 - 0.01037), b=3.04 (2.89 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.35 se; based on food items.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tm=5-6; tmax=17; K=0.13-0.17; Fec=6,100-72,000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (25 of 100).
