Estimates based on models

Preferred temperature (Ref. 123201): 26.4 - 28.2, mean 27.5 °C (based on 541 cells).

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

Bayesian length-weight: a=0.00933 (0.00410 - 0.02122), b=3.10 (2.91 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.36 se; based on food items.

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

Nutrients (Ref. 124155): Calcium = 99.3 [37.7, 233.6] mg/100g; Iron = 0.876 [0.441, 1.690] mg/100g; Protein = 19.3 [18.1, 20.5] %; Omega3 = 0.211 [0.104, 0.435] g/100g; Selenium = 6.41 [2.58, 15.63] μg/100g; VitaminA = 145 [39, 563] μg/100g; Zinc = 1.76 [1.02, 2.88] mg/100g (wet weight);
