Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 4.5, mean 3.1 °C (based on 187 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00762 - 0.03006), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.1 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=12).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100).
