Estimates based on models

Preferred temperature (Ref. 123201): 25.4 - 29, mean 28 °C (based on 268 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [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): 3.3 ±0.5 se; based on size and trophs of closest relatives

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

Nutrients (Ref. 124155): Calcium = 217 [102, 392] mg/100g; Iron = 1.11 [0.61, 2.03] mg/100g; Protein = 18.4 [17.1, 19.7] %; Omega3 = 0.146 [0.073, 0.282] g/100g; Selenium = 26.5 [11.5, 55.4] μg/100g; VitaminA = 98.1 [26.6, 359.1] μg/100g; Zinc = 2.2 [1.4, 3.4] mg/100g (wet weight);
