Estimates based on models

Preferred temperature (Ref. 123201): 0.2 - 6.6, mean 2.7 °C (based on 698 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00437 - 0.01257), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (62 of 100).
