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=0.00372 (0.00286 - 0.00483), b=2.99 (2.93 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Fec>1000).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 210 [137, 386] mg/100g; Iron = 1.84 [1.13, 3.19] mg/100g; Protein = 17.5 [16.1, 18.9] %; Omega3 = 0.148 [0.075, 0.280] g/100g; Selenium = 54.4 [27.3, 109.2] μg/100g; VitaminA = 26.3 [11.8, 56.9] μg/100g; Zinc = 1.15 [0.86, 1.53] mg/100g (wet weight); based on nutrient studies.
