Estimates based on models

Preferred temperature (Ref. 123201): 10 - 13.1, mean 11.8 °C (based on 11 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.9   ±0.2 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
