Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00774 - 0.05639), b=3.03 (2.79 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fecundity 60-70).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
