Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 6.8, mean 4.5 °C (based on 226 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00722 - 0.02095), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=11).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
