Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.3, mean 27.3 °C (based on 182 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):  4.0   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 8,000-12,000).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100). 🛈
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 36 [20, 67] mg/100g; Iron = 0.462 [0.279, 0.977] mg/100g; Protein = 18.8 [16.5, 21.3] %; Omega3 = 0.11 [0.05, 0.31] g/100g; Selenium = 38.1 [21.2, 75.7] μg/100g; VitaminA = 73.4 [22.6, 225.2] μg/100g; Zinc = 0.972 [0.691, 1.341] mg/100g (wet weight);
