Estimates based on models

Preferred temperature (Ref. 123201): 3.3 - 6.4, mean 5.4 °C (based on 116 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00253 - 0.01042), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.2   ±0.38 se; based on food items.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100).
價格種類 (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 35.8 [4.9, 1,067.6] mg/100g; Iron = 0.421 [0.037, 5.886] mg/100g; Protein = 12.9 [10.9, 14.8] %; Omega3 = 1.26 [0.27, 5.59] g/100g; Selenium = 4.89 [0.54, 35.66] μg/100g; VitaminA = 294 [9, 7,487] μg/100g; Zinc = 1.6 [0.1, 18.3] mg/100g (wet weight); based on nutrient studies.
