Estimates based on models

Preferred temperature (Ref. 123201): 3.3 - 7.1, mean 5.2 °C (based on 167 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.00 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
