Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 12.3, mean 5.5 °C (based on 3390 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00160 - 0.00625), b=2.94 (2.76 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.53 se; based on food items.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.8, Fecundity assumed < 1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
