Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.9, mean 27.7 °C (based on 706 cells).

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

Bayesian length-weight: a=0.02754 (0.01595 - 0.04755), b=2.97 (2.82 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 33.9 [20.0, 65.5] mg/100g; Iron = 0.527 [0.268, 0.925] mg/100g; Protein = 18.6 [17.4, 19.7] %; Omega3 = 0.114 [0.070, 0.214] g/100g; Selenium = 36.4 [18.8, 66.9] μg/100g; VitaminA = 50.9 [14.8, 166.1] μg/100g; Zinc = 1.47 [1.01, 2.13] mg/100g (wet weight);
