Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02692 (0.01216 - 0.05956), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  2.9   ±0.33 se; based on food items.
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 301 [91, 669] mg/100g; Iron = 1.55 [0.82, 3.10] mg/100g; Protein = 16.4 [13.8, 19.3] %; Omega3 = 0.39 [0.14, 1.19] g/100g; Selenium = 65 [24, 154] μg/100g; VitaminA = 51.3 [13.2, 165.0] μg/100g; Zinc = 3.83 [1.45, 6.68] mg/100g (wet weight); based on nutrient studies.
