Estimates based on models
Preferred temperature (Ref.
123201): 15.1 - 25.5, mean 20.3 °C (based on 4 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01444 - 0.05017), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.0 se; based on diet studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 125 [63, 197] mg/100g; Iron = 0.957 [0.555, 1.659] mg/100g; Protein = 18.5 [17.3, 19.7] %; Omega3 = 0.139 [0.077, 0.248] g/100g; Selenium = 44.9 [22.7, 86.3] μg/100g; VitaminA = 47 [13, 175] μg/100g; Zinc = 1.63 [1.08, 2.38] mg/100g (wet weight);
