Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00551 - 0.00792), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming tm=5-10).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (83 of 100).
