Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00729 - 0.01727), b=3.19 (3.06 - 3.32), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.5 ±0.1 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (47 of 100).

Nutrients (Ref. 124155): Calcium = 77.1 [22.2, 187.0] mg/100g; Iron = 1.12 [0.49, 2.53] mg/100g; Protein = 17.6 [15.5, 20.0] %; Omega3 = 0.169 [0.060, 0.464] g/100g; Selenium = 50.1 [18.9, 121.7] μg/100g; VitaminA = 38.1 [9.7, 118.7] μg/100g; Zinc = 2.22 [1.48, 3.31] mg/100g (wet weight);
