Estimates based on models
Preferred temperature (Ref.
123201): 21.1 - 27.4, mean 24 °C (based on 44 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00493 - 0.02329), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.6 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 = 201 [88, 465] mg/100g; Iron = 1.74 [0.90, 3.35] mg/100g; Protein = 18.1 [16.4, 19.9] %; Omega3 = 0.711 [0.304, 1.916] g/100g; Selenium = 21.2 [9.4, 49.2] μg/100g; VitaminA = 33 [12, 91] μg/100g; Zinc = 1.15 [0.77, 1.69] mg/100g (wet weight);
