Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 7.5, mean 4.1 °C (based on 265 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5159   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00200 - 0.01144), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 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):  Low to moderate vulnerability (32 of 100).
Price category (Ref. 80766):   Unknown.
