Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 28.9, mean 27.7 °C (based on 166 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00642 - 0.03257), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
Nutrients (Ref.
124155): Calcium = 34.9 [17.2, 80.0] mg/100g; Iron = 0.648 [0.306, 1.487] mg/100g; Protein = 18.5 [17.0, 20.0] %; Omega3 = 0.1 [0.1, 0.2] g/100g; Selenium = 21.7 [8.7, 54.3] μg/100g; VitaminA = 32.8 [7.7, 133.2] μg/100g; Zinc = 1.33 [0.52, 2.82] mg/100g (wet weight);
