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=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.5 ±0.4 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.
