Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 5, mean 4.2 °C (based on 340 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this BS (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
