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=0.01950 (0.01145 - 0.03321), b=2.91 (2.77 - 3.05), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.4 ±0.1 se; based on size and trophs of closest relatives
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
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 = 419 [167, 1,788] mg/100g; Iron = 1.56 [0.51, 4.22] mg/100g; Protein = 17.3 [15.8, 18.8] %; Omega3 = 0.176 [0.065, 0.472] g/100g; Selenium = 7.92 [2.10, 38.26] μg/100g; VitaminA = 271 [52, 1,310] μg/100g; Zinc = 8.15 [2.49, 17.42] mg/100g (wet weight);
