Estimates based on models

Preferred temperature (Ref. 123201): -1.6 - 1.8, mean -0.6 °C (based on 1824 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00160 - 0.00822), b=3.19 (2.99 - 3.39), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on diet studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tm=2-4;Fec<2000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
