Estimates based on models

Preferred temperature (Ref. 123201): 26.3 - 29.3, mean 28.6 °C (based on 2566 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): 3.9 ±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): Moderate vulnerability (43 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 36.5 [20.1, 69.3] mg/100g; Iron = 0.47 [0.28, 0.98] mg/100g; Protein = 18.7 [16.5, 21.3] %; Omega3 = 0.124 [0.056, 0.349] g/100g; Selenium = 46 [25, 89] μg/100g; VitaminA = 75.7 [23.7, 228.6] μg/100g; Zinc = 0.964 [0.684, 1.324] mg/100g (wet weight);
