Estimates based on models

Preferred temperature (Ref. 123201): 2 - 8.8, mean 7.6 °C (based on 26 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00155 (0.00068 - 0.00355), b=2.92 (2.72 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
