Estimates based on models
Preferred temperature (Ref.
123201): 9.3 - 15.2, mean 12.6 °C (based on 12 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5044 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00162 - 0.01121), b=3.16 (2.93 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.6 ±0.3 se; based on size and trophs of closest relatives
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
