Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00447 - 0.01122), b=2.92 (2.79 - 3.05), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.7 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (22 of 100).
