Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tm=0.5-1.5; Fec=20-40; assuming multiple pregnancies per year).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
