Estimates based on models

Preferred temperature (Ref. 123201): 2 - 9, mean 6.1 °C (based on 368 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
