Estimates based on models
Preferred temperature (Ref.
123201): 24.2 - 29.3, mean 28.2 °C (based on 3609 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.5 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 (10 of 100).
Nutrients (Ref.
124155): Calcium = 145 [75, 318] mg/100g; Iron = 0.901 [0.436, 1.668] mg/100g; Protein = 18.8 [16.9, 20.4] %; Omega3 = 0.167 [0.072, 0.319] g/100g; Selenium = 19.4 [9.1, 46.2] μg/100g; VitaminA = 132 [35, 451] μg/100g; Zinc = 2.47 [1.63, 3.64] mg/100g (wet weight);
