Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00617 - 0.00890), b=3.06 (3.01 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=5).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Prijsklasse (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 81.9 [42.2, 233.9] mg/100g; Iron = 1.15 [0.72, 2.11] mg/100g; Protein = 18.3 [16.6, 20.1] %; Omega3 = 0.462 [0.249, 0.869] g/100g; Selenium = 25 [13, 50] μg/100g; VitaminA = 11.3 [4.4, 30.8] μg/100g; Zinc = 0.817 [0.547, 1.239] mg/100g (wet weight);
