Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.01573 - 0.02417), b=2.96 (2.91 - 3.01), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.4 ±0.18 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): Low to moderate vulnerability (31 of 100).
Nutrients (Ref.
124155): Calcium = 33 [14, 178] mg/100g; Iron = 2.82 [0.72, 6.67] mg/100g; Protein = 18.1 [15.7, 20.5] %; Omega3 = 0.441 [0.162, 1.169] g/100g; Selenium = 91.9 [38.8, 199.6] μg/100g; VitaminA = 36.2 [13.3, 84.7] μg/100g; Zinc = 2 [1, 3] mg/100g (wet weight); based on
nutrient studies.
