Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00223), b=2.98 (2.77 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.4 ±0.5 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).
