Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00318 - 0.01897), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
