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=0.01072 (0.00788 - 0.01457), b=3.09 (3.04 - 3.14), in cm total length, based on LWR estimates for this species (Ref. 93245).
营养阶层 (Ref. 69278):  4.0   ±0.60 se; based on food items.
Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Fec=21).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
价格分类 (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 66.8 [17.7, 163.7] mg/100g; Iron = 1.5 [0.8, 3.5] mg/100g; Protein = 19.1 [17.1, 21.3] %; Omega3 = 0.824 [0.336, 2.190] g/100g; Selenium = 32.2 [13.3, 69.7] μg/100g; VitaminA = 51 [17, 144] μg/100g; Zinc = 1 [1, 1] mg/100g (wet weight);
