Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03236 (0.02006 - 0.05221), b=2.87 (2.74 - 3.00), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
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 = 99 [54, 196] mg/100g ; Iron = 1.31 [0.74, 2.34] mg/100g ; Protein = 16.2 [15.0, 17.4] % ; Omega3 = 0.284 [0.111, 0.721] g/100g ; Selenium = 117 [48, 296] μg/100g ; VitaminA = 26.1 [8.9, 70.3] μg/100g ; Zinc = 1.73 [1.15, 2.58] mg/100g (wet weight);
