Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00368 - 0.01243), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.4 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).
