Estimates based on models
Preferred temperature (Ref.
123201): 11.7 - 16.5, mean 14.2 °C (based on 12 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trofisch niveau (Ref.
69278): 4.0 ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary low fecundity).
Fishing Vulnerability (Ref.
