Estimates based on models
Preferred temperature (Ref.
123201): 25.1 - 29.3, mean 28.2 °C (based on 2065 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±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 = 221 [118, 488] mg/100g; Iron = 1.32 [0.64, 2.38] mg/100g; Protein = 17.9 [16.6, 19.2] %; Omega3 = 0.111 [0.055, 0.236] g/100g; Selenium = 33.2 [14.0, 85.8] μg/100g; VitaminA = 65.4 [18.4, 226.9] μg/100g; Zinc = 2.57 [1.56, 3.99] mg/100g (wet weight);
