Estimates based on models

Preferred temperature (Ref. 123201): 25 - 29.4, mean 28.2 °C (based on 1154 cells).

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

Bayesian length-weight: a=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 59.2 [32.9, 117.2] mg/100g; Iron = 0.56 [0.33, 1.13] mg/100g; Protein = 18.8 [16.5, 21.4] %; Omega3 = 0.118 [0.053, 0.342] g/100g; Selenium = 27.9 [14.9, 58.9] μg/100g; VitaminA = 101 [30, 317] μg/100g; Zinc = 1.16 [0.81, 1.62] mg/100g (wet weight);
