Estimates based on models

Preferred temperature (Ref. 123201): -1.6 - 3.2, mean -0.1 °C (based on 2085 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00135 - 0.00777), b=3.15 (2.94 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.35 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
