Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29.3, mean 28.2 °C (based on 900 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02344 (0.01098 - 0.05004), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 44.1 [26.8, 74.2] mg/100g; Iron = 0.265 [0.142, 0.647] mg/100g; Protein = 18.1 [16.8, 19.3] %; Omega3 = 0.123 [0.078, 0.199] g/100g; Selenium = 17 [10, 30] μg/100g; VitaminA = 55.5 [13.1, 214.6] μg/100g; Zinc = 0.442 [0.327, 1.494] mg/100g (wet weight);
