Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 5.5, mean 1.6 °C (based on 106 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6289   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00533 - 0.02257), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.8 se; based on diet studies.
Generation time: 8.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (59 of 100).
