Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.01455 - 0.02737), b=2.99 (2.90 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
栄養段階 (Ref. 69278):  2.6   ±0.29 se; based on food items.
Generation time: 6.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  手段, 1.4年~4.4年の倍増期間の最小個体群 (K=0.18).
Fishing Vulnerability (Ref. 59153):  High vulnerability (55 of 100).
価格帯 (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 56.6 [28.9, 133.9] mg/100g; Iron = 1.37 [0.78, 2.37] mg/100g; Protein = 17.6 [16.4, 18.8] %; Omega3 = 0.561 [0.217, 1.476] g/100g; Selenium = 34.3 [14.6, 75.2] μg/100g; VitaminA = 15.2 [5.2, 42.0] μg/100g; Zinc = 1.1 [0.7, 1.6] mg/100g (wet weight);
