Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00406 - 0.01955), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (46 of 100).
Nutrients (Ref.
124155): Calcium = 53.7 [34.1, 85.5] mg/100g; Iron = 1.23 [0.78, 1.92] mg/100g; Protein = 18.5 [16.5, 20.6] %; Omega3 = 0.422 [0.282, 0.628] g/100g; Selenium = 32 [19, 55] μg/100g; VitaminA = 16.8 [6.9, 42.4] μg/100g; Zinc = 0.666 [0.495, 0.918] mg/100g (wet weight); based on
nutrient studies.
