Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00168 - 0.00901), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100).
Nutrients (Ref. 124155):  Calcium = 15 [3, 74] mg/100g; Iron = 0.552 [0.142, 1.667] mg/100g; Protein = 19.7 [17.4, 22.0] %; Omega3 = 0.27 [0.10, 0.78] g/100g; Selenium = 27.5 [7.9, 98.4] μg/100g; VitaminA = 31.4 [7.8, 139.6] μg/100g; Zinc = 0.658 [0.308, 1.290] mg/100g (wet weight);
