Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.1, mean 28.2 °C (based on 1838 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00538 - 0.01228), b=3.07 (2.95 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.29-0.52; tmax=8).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 40.5 [14.2, 156.2] mg/100g; Iron = 0.578 [0.238, 1.642] mg/100g; Protein = 19.1 [17.3, 21.0] %; Omega3 = 0.206 [0.112, 0.346] g/100g; Selenium = 84.9 [44.5, 168.2] μg/100g; VitaminA = 9.38 [2.40, 34.23] μg/100g; Zinc = 0.722 [0.405, 1.471] mg/100g (wet weight); based on nutrient studies.
