Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 4.1, mean 2.3 °C (based on 2932 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00171 - 0.00885), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±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 presumed to be <10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
