Estimates based on models
Preferred temperature (Ref.
123201): 24.8 - 29.2, mean 27.5 °C (based on 233 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00803 - 0.05439), b=2.98 (2.75 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
Nutrients (Ref.
124155): Calcium = 52.4 [20.4, 149.7] mg/100g; Iron = 0.709 [0.277, 1.756] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.066 [0.029, 0.146] g/100g; Selenium = 13.2 [4.0, 39.6] μg/100g; VitaminA = 42.1 [9.8, 167.6] μg/100g; Zinc = 2.25 [1.06, 4.02] mg/100g (wet weight);
