Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00311 - 0.01538), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
