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=0.00661 (0.00393 - 0.01110), b=2.91 (2.77 - 3.05), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
Nutrients (Ref.
124155): Calcium = 194 [107, 394] mg/100g; Iron = 1.06 [0.58, 1.95] mg/100g; Protein = 17.6 [15.7, 19.1] %; Omega3 = 0.144 [0.061, 0.284] g/100g; Selenium = 46.1 [24.1, 97.4] μg/100g; VitaminA = 23.2 [7.8, 57.8] μg/100g; Zinc = 1.74 [1.25, 2.49] mg/100g (wet weight);
