Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01097 - 0.04568), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 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 = 58.1 [26.2, 100.5] mg/100g; Iron = 0.876 [0.466, 1.615] mg/100g; Protein = 19.3 [18.0, 20.5] %; Omega3 = 0.178 [0.094, 0.336] g/100g; Selenium = 16.3 [7.4, 34.7] μg/100g; VitaminA = 42.7 [10.6, 175.5] μg/100g; Zinc = 0.812 [0.496, 1.264] mg/100g (wet weight);
