Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00418 - 0.02283), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.39 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 (30 of 100).
Nutrients (Ref.
124155): Calcium = 99.6 [49.0, 182.3] mg/100g; Iron = 0.834 [0.376, 1.552] mg/100g; Protein = 16.1 [13.8, 18.5] %; Omega3 = 0.191 [0.080, 0.420] g/100g; Selenium = 88.8 [44.8, 183.2] μg/100g; VitaminA = 26.1 [7.9, 78.2] μg/100g; Zinc = 1.18 [0.79, 1.69] mg/100g (wet weight);
