Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 6.1, mean 5.1 °C (based on 140 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00273 - 0.01106), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).
