Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00594 - 0.00843), b=3.11 (3.06 - 3.16), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.47 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 (29 of 100).
Nutrients (Ref.
124155): Calcium = 131 [53, 288] mg/100g; Iron = 1.52 [0.82, 3.07] mg/100g; Protein = 16.8 [15.6, 18.2] %; Omega3 = 0.295 [0.126, 0.692] g/100g; Selenium = 77.4 [35.5, 201.7] μg/100g; VitaminA = 29.3 [12.3, 65.9] μg/100g; Zinc = 1.61 [1.15, 2.27] mg/100g (wet weight); based on
nutrient studies.
