Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00599 - 0.03330), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
Nutrients (Ref.
124155): Calcium = 146 [61, 371] mg/100g; Iron = 2.15 [1.07, 5.55] mg/100g; Protein = 19.5 [17.3, 21.8] %; Omega3 = 0.67 [0.25, 1.85] g/100g; Selenium = 55.4 [20.0, 173.9] μg/100g; VitaminA = 37.1 [12.5, 113.0] μg/100g; Zinc = 1.65 [1.12, 2.49] mg/100g (wet weight);
