Estimates based on models
Preferred temperature (Ref.
123201): 3.1 - 3.9, mean 3.7 °C (based on 6 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 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).
Trofisch niveau (Ref.
69278): 4.0 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec assumed to be <10).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (54 of 100).
