Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00543 - 0.02542), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.8 ±0.3 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 to moderate vulnerability (33 of 100).
