Estimates based on models

Preferred temperature (Ref. 123201): 6.7 - 9.9, mean 7.8 °C (based on 14 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (tmax=90; tm=20; K=0.04-0.06).
Prior r = 0.20, 95% CL = 0.13 - 0.30, Based on 1 full stock assessment.
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (71 of 100).
