Estimates based on models

Preferred temperature (Ref. 123201): 3.3 - 9.6, mean 5.8 °C (based on 761 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
