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=0.00676 (0.00293 - 0.01558), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High vulnerability (58 of 100).
Nutrients (Ref. 124155):  Calcium = 17 [4, 86] mg/100g; Iron = 0.77 [0.20, 2.26] mg/100g; Protein = 19.6 [17.5, 21.5] %; Omega3 = 0.38 [0.17, 0.82] g/100g; Selenium = 27.1 [8.6, 81.5] μg/100g; VitaminA = 14.3 [4.6, 47.2] μg/100g; Zinc = 0.511 [0.248, 0.943] mg/100g (wet weight);
