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=0.00513 (0.00204 - 0.01288), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.0 ±0.37 se; based on food items.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 232 [77, 562] mg/100g; Iron = 1.41 [0.65, 2.85] mg/100g; Protein = 16.8 [15.0, 18.7] %; Omega3 = 0.387 [0.114, 1.114] g/100g; Selenium = 73.6 [21.9, 279.0] μg/100g; VitaminA = 159 [42, 669] μg/100g; Zinc = 3.15 [1.89, 4.97] mg/100g (wet weight);
