Estimates based on models

Preferred temperature (Ref. 123201): 25.6 - 28.7, mean 27.5 °C (based on 531 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02239 (0.01117 - 0.04486), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

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 = 95.4 [49.7, 148.0] mg/100g; Iron = 0.792 [0.470, 1.294] mg/100g; Protein = 18.7 [17.6, 19.9] %; Omega3 = 0.119 [0.073, 0.189] g/100g; Selenium = 30.9 [17.5, 58.4] μg/100g; VitaminA = 51.4 [15.7, 165.8] μg/100g; Zinc = 1.34 [0.91, 1.93] mg/100g (wet weight);
