Estimates based on models

Preferred temperature (Ref. 123201): 16.1 - 25.2, mean 22 °C (based on 329 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).

Trophic level (Ref. 69278): 3.6 ±0.50 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 13.1 [5.4, 24.6] mg/100g; Iron = 0.203 [0.100, 0.367] mg/100g; Protein = 19.4 [18.1, 20.6] %; Omega3 = 0.212 [0.105, 0.438] g/100g; Selenium = 7.93 [3.45, 19.64] μg/100g; VitaminA = 17.5 [3.8, 83.2] μg/100g; Zinc = 0.464 [0.286, 0.749] mg/100g (wet weight);
