Estimates based on models
Preferred temperature (Ref.
123201): 20.2 - 29.2, mean 26.9 °C (based on 43417 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 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): Moderate vulnerability (41 of 100).
Nutrients (Ref.
124155): Calcium = 167 [64, 396] mg/100g; Iron = 1.55 [0.67, 3.54] mg/100g; Protein = 18.2 [15.7, 20.6] %; Omega3 = 0.224 [0.091, 0.652] g/100g; Selenium = 10.7 [4.1, 29.3] μg/100g; VitaminA = 21.4 [5.4, 94.5] μg/100g; Zinc = 0.862 [0.517, 1.441] mg/100g (wet weight);
