Estimates based on models

Preferred temperature (Ref. 123201): 22.5 - 27.5, mean 26.3 °C (based on 184 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03236 (0.01318 - 0.07944), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 24 [11, 44] mg/100g; Iron = 0.491 [0.279, 0.847] mg/100g; Protein = 19.1 [17.9, 20.3] %; Omega3 = 0.14 [0.08, 0.24] g/100g; Selenium = 16.5 [7.7, 34.7] μg/100g; VitaminA = 35.6 [8.6, 140.4] μg/100g; Zinc = 0.796 [0.517, 1.202] mg/100g (wet weight);
