Estimates based on models

Preferred temperature (Ref. 123201): 0 - 1.6, mean 1.2 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00287 - 0.01207), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 5,610-12,900;).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (15 of 100).
