Estimates based on models
Preferred temperature (Ref.
123201): 24.6 - 29.3, mean 27.3 °C (based on 160 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.61 se; based on food items.
Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (15 of 100).
Nutrients (Ref.
124155): Calcium = 124 [64, 193] mg/100g; Iron = 0.879 [0.518, 1.468] mg/100g; Protein = 18.6 [17.5, 19.8] %; Omega3 = 0.114 [0.068, 0.187] g/100g; Selenium = 26 [14, 50] μg/100g; VitaminA = 57.4 [17.2, 188.2] μg/100g; Zinc = 1.58 [1.05, 2.31] mg/100g (wet weight);
