Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00776 - 0.00934), b=3.08 (3.06 - 3.10), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
Nutrients (Ref.
124155): Calcium = 72.5 [30.4, 154.0] mg/100g; Iron = 1.15 [0.54, 2.12] mg/100g; Protein = 19.4 [18.2, 20.6] %; Omega3 = 0.723 [0.278, 1.950] g/100g; Selenium = 37.4 [14.0, 93.2] μg/100g; VitaminA = 38 [12, 142] μg/100g; Zinc = 1.17 [0.77, 1.78] mg/100g (wet weight);
