Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00611 - 0.00859), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).
Niveau trophique (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.
Résilience (Ref. 120179):  Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=5).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
Catégorie de prix (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);
