Estimates based on models

Preferred temperature (Ref. 123201): -0.6 - 3.3, mean 0.6 °C (based on 139 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Fecundity assumed < 1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
