Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.6406   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00091 - 0.00578), b=3.19 (2.97 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.0   ±0.67 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Prijsklasse (Ref. 80766):   Unknown.
