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=0.01202 (0.00496 - 0.02912), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.43 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 vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 558 [287, 1,566] mg/100g; Iron = 2.1 [1.1, 4.4] mg/100g; Protein = 18.4 [16.6, 20.0] %; Omega3 = 0.228 [0.113, 0.468] g/100g; Selenium = 24.1 [10.2, 55.3] μg/100g; VitaminA = 30.9 [10.1, 92.8] μg/100g; Zinc = 2.81 [1.80, 4.40] mg/100g (wet weight);
