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=0.01413 (0.01042 - 0.01915), b=2.91 (2.84 - 2.98), in cm total length, based on LWR estimates for this species (Ref. 93245).
栄養段階 (Ref. 69278):  2.7   ±0.30 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (19 of 100).
価格帯 (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 129 [39, 297] mg/100g; Iron = 1.45 [0.71, 3.21] mg/100g; Protein = 18 [16, 20] %; Omega3 = 0.4 [0.1, 1.1] g/100g; Selenium = 46.5 [20.9, 99.7] μg/100g; VitaminA = 65.9 [23.0, 160.6] μg/100g; Zinc = 2.4 [1.7, 3.4] mg/100g (wet weight);
