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=0.01047 (0.00471 - 0.02328), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±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): Low to moderate vulnerability (27 of 100).

Nutrients (Ref. 124155): Calcium = 163 [94, 343] mg/100g; Iron = 1.52 [0.92, 2.40] mg/100g; Protein = 16.7 [15.8, 17.7] %; Omega3 = 0.315 [0.136, 0.749] g/100g; Selenium = 65.1 [29.0, 174.3] μg/100g; VitaminA = 38.2 [15.6, 86.2] μg/100g; Zinc = 1.62 [1.14, 2.28] mg/100g (wet weight);
