Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Nutrients (Ref. 124155): Calcium = 7.64 [1.39, 39.72] mg/100g; Iron = 0.339 [0.081, 1.055] mg/100g; Protein = 16.4 [13.6, 19.1] %; Omega3 = 0.543 [0.159, 2.003] g/100g; Selenium = 16.1 [4.1, 52.2] μg/100g; VitaminA = 7.34 [1.81, 30.37] μg/100g; Zinc = 0.373 [0.185, 0.692] mg/100g (wet weight);
