Estimates based on models

Preferred temperature (Ref. 123201): 0.2 - 5.5, mean 3.2 °C (based on 352 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
