Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 28.1, mean 26.9 °C (based on 404 cells).

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

Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.25 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 135 [69, 209] mg/100g; Iron = 0.98 [0.58, 1.64] mg/100g; Protein = 18.4 [17.2, 19.5] %; Omega3 = 0.113 [0.067, 0.191] g/100g; Selenium = 34.5 [18.7, 67.4] μg/100g; VitaminA = 43.6 [11.8, 152.9] μg/100g; Zinc = 1.83 [1.22, 2.66] mg/100g (wet weight);
