Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00792 - 0.01322), b=2.83 (2.78 - 2.88), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 2.5 ±0.86 se; based on food items.
回復力 (Ref.
120179): 低的, 最小族群倍增時間4.5 - 14 年 (Assuming tm=5-10; Fec < 1,000).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (73 of 100).
Nutrients (Ref.
124155): Calcium = 187 [40, 394] mg/100g; Iron = 1.12 [0.44, 2.77] mg/100g; Protein = 18.4 [15.7, 20.6] %; Omega3 = 0.452 [0.181, 1.191] g/100g; Selenium = 96 [36, 210] μg/100g; VitaminA = 23 [8, 65] μg/100g; Zinc = 2.69 [0.60, 7.23] mg/100g (wet weight); based on
nutrient studies.
