Estimates based on models

Preferred temperature (Ref. 123201): 19.5 - 28.9, mean 27.4 °C (based on 1078 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.50 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Catégorie de prix (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 32.4 [16.4, 51.7] mg/100g; Iron = 0.554 [0.322, 0.885] mg/100g; Protein = 18.9 [17.8, 20.1] %; Omega3 = 0.104 [0.064, 0.170] g/100g; Selenium = 62.7 [35.4, 115.6] μg/100g; VitaminA = 22.7 [6.6, 78.6] μg/100g; Zinc = 0.85 [0.59, 1.24] mg/100g (wet weight);
