Estimates based on models

Preferred temperature (Ref. 123201): -0.4 - 6.9, mean 2.4 °C (based on 1768 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00371 - 0.01290), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec=10-100).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
