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=0.00708 (0.00376 - 0.01332), b=3.11 (2.95 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.31 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 103 [46, 491] mg/100g; Iron = 0.696 [0.253, 2.276] mg/100g; Protein = 17.7 [15.3, 19.9] %; Omega3 = 0.189 [0.077, 0.397] g/100g; Selenium = 68.8 [32.3, 187.6] μg/100g; VitaminA = 26.4 [7.5, 80.1] μg/100g; Zinc = 2 [1, 3] mg/100g (wet weight);
