Estimates based on models
Preferred temperature (Ref.
123201): 24.7 - 29.1, mean 28.2 °C (based on 1174 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00624 - 0.01928), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
Nutrients (Ref.
124155): Calcium = 489 [120, 1,600] mg/100g; Iron = 1.53 [0.57, 3.46] mg/100g; Protein = 18.7 [16.8, 20.8] %; Omega3 = 0.254 [0.133, 0.433] g/100g; Selenium = 85.9 [29.6, 260.9] μg/100g; VitaminA = 24.4 [9.3, 68.8] μg/100g; Zinc = 1.94 [0.91, 3.35] mg/100g (wet weight);
