Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00611 - 0.00859), b=3.07 (3.02 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 3.6 ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 非常低的, 最小族群倍增時間超過14 年 (Fec=5).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (44 of 100).
Nutrients (Ref.
124155): Calcium = 81.9 [42.2, 233.9] mg/100g; Iron = 1.15 [0.72, 2.11] mg/100g; Protein = 18.3 [16.6, 20.1] %; Omega3 = 0.462 [0.249, 0.869] g/100g; Selenium = 25 [13, 50] μg/100g; VitaminA = 11.3 [4.4, 30.8] μg/100g; Zinc = 0.817 [0.547, 1.239] mg/100g (wet weight);
