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=0.00794 (0.00619 - 0.01019), b=3.05 (3.01 - 3.09), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 7.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (K=0.14-0.18; Fec=64,770).
Fishing Vulnerability (Ref.
59153): High vulnerability (58 of 100).
Nutrients (Ref.
