Estimates based on models
Preferred temperature (Ref.
123201): 14.1 - 28.1, mean 23.6 °C (based on 1345 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), 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): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
Nutrients (Ref.
124155): Calcium = 481 [159, 1,454] mg/100g; Iron = 4.95 [1.76, 11.62] mg/100g; Protein = 19.9 [18.5, 21.4] %; Omega3 = 0.369 [0.177, 0.790] g/100g; Selenium = 98.4 [31.3, 289.6] μg/100g; VitaminA = 15 [4, 62] μg/100g; Zinc = 1.28 [0.72, 2.35] mg/100g (wet weight);
