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=0.00537 (0.00262 - 0.01101), b=3.22 (3.06 - 3.38), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
