Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Assuming Fec<1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
