Estimates based on models

Preferred temperature (Ref. 123201): 23.3 - 27.9, mean 26.4 °C (based on 459 cells).

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

Bayesian length-weight: a=0.00407 (0.00237 - 0.00700), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tm<1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 166 [72, 461] mg/100g; Iron = 1.91 [0.82, 4.18] mg/100g; Protein = 20.1 [18.3, 21.9] %; Omega3 = 0.375 [0.180, 0.781] g/100g; Selenium = 47.3 [17.0, 122.9] μg/100g; VitaminA = 3.98 [1.05, 15.64] μg/100g; Zinc = 1.04 [0.62, 1.78] mg/100g (wet weight);
