Estimates based on models

Preferred temperature (Ref. 123201): 2.5 - 5.4, mean 3.8 °C (based on 68 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.9   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec=2).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
