Estimates based on models
Preferred temperature (Ref.
123201): 24.7 - 29.4, mean 27.9 °C (based on 991 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): 4.2 ±0.2 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 = 94.9 [47.4, 172.7] mg/100g; Iron = 0.794 [0.437, 1.393] mg/100g; Protein = 19 [18, 20] %; Omega3 = 0.138 [0.079, 0.237] g/100g; Selenium = 32 [16, 64] μg/100g; VitaminA = 58 [16, 205] μg/100g; Zinc = 1.18 [0.77, 1.78] mg/100g (wet weight);
