Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
