Estimates based on models

Preferred temperature (Ref. 123201): 23.4 - 27.1, mean 24.8 °C (based on 190 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00609 - 0.01719), b=3.06 (2.92 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.3 se; based on diet studies.
Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 65.5 [35.9, 126.6] mg/100g; Iron = 1.01 [0.53, 1.76] mg/100g; Protein = 19.1 [17.6, 20.8] %; Omega3 = 0.372 [0.217, 0.586] g/100g; Selenium = 26.9 [14.2, 52.0] μg/100g; VitaminA = 16 [5, 55] μg/100g; Zinc = 0.64 [0.46, 0.93] mg/100g (wet weight); based on nutrient studies.
