Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00391 - 0.01767), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.7 se; based on size and trophs of closest relatives
Generation time: 2.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 45.1 [26.1, 82.1] mg/100g; Iron = 0.778 [0.409, 1.357] mg/100g; Protein = 18.4 [16.9, 20.2] %; Omega3 = 0.35 [0.19, 0.60] g/100g; Selenium = 29.9 [16.5, 56.3] μg/100g; VitaminA = 22.1 [7.9, 72.1] μg/100g; Zinc = 0.681 [0.496, 0.978] mg/100g (wet weight);
