Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.3, mean 27.3 °C (based on 182 cells).

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

Bayesian length-weight: a=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Fec = 8,000-12,000).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 36 [20, 67] mg/100g; Iron = 0.462 [0.279, 0.977] mg/100g; Protein = 18.8 [16.5, 21.3] %; Omega3 = 0.11 [0.05, 0.31] g/100g; Selenium = 38.1 [21.2, 75.7] μg/100g; VitaminA = 73.4 [22.6, 225.2] μg/100g; Zinc = 0.972 [0.691, 1.341] mg/100g (wet weight);
