Estimates based on models

Preferred temperature (Ref. 123201): -1.8 - 0.8, mean -0.8 °C (based on 568 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00120 - 0.00437), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 200).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
