Estimates based on models

Preferred temperature (Ref. 123201): 7.9 - 13.5, mean 9.7 °C (based on 39 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00723 - 0.03808), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.6   ±0.6 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
