Estimates based on models

Preferred temperature (Ref. 123201): 23.1 - 29.1, mean 27 °C (based on 176 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00386 - 0.01791), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.71 se; based on food items.
Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.32; assuming tm>=2).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 81.3 [48.0, 153.2] mg/100g; Iron = 0.869 [0.447, 1.519] mg/100g; Protein = 18.8 [17.3, 20.5] %; Omega3 = 0.203 [0.110, 0.335] g/100g; Selenium = 57.3 [30.0, 114.7] μg/100g; VitaminA = 11 [4, 31] μg/100g; Zinc = 0.879 [0.637, 1.265] mg/100g (wet weight);
