Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00591 - 0.00810), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.8 ±0.6 se; based on diet studies.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (72 of 100).
Nutrients (Ref.
124155): Calcium = 41.8 [21.8, 91.0] mg/100g; Iron = 0.66 [0.39, 1.14] mg/100g; Protein = 16.9 [15.2, 18.9] %; Omega3 = 0.229 [0.119, 0.448] g/100g; Selenium = 74.8 [37.6, 156.9] μg/100g; VitaminA = 21.3 [7.6, 57.8] μg/100g; Zinc = 1.12 [0.74, 1.78] mg/100g (wet weight);
