Estimates based on models
Preferred temperature (Ref.
123201): -1.3 - 1.2, mean -0.1 °C (based on 18 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00293 - 0.01422), b=3.17 (2.97 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.1 se; based on diet studies.
Generation time: 4.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (K=0.24; tm=4; Fec = 4,666).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (47 of 100).
Climate Vulnerability (Ref.
125649): High to very high vulnerability (73 of 100).
Nutrients (Ref.
124155): Calcium = 23.2 [14.6, 53.2] mg/100g; Iron = 0.503 [0.205, 0.955] mg/100g; Protein = 17.8 [16.2, 19.5] %; Omega3 = 0.358 [0.209, 0.605] g/100g; Selenium = 17.6 [7.7, 37.3] μg/100g; VitaminA = 12.6 [2.9, 55.6] μg/100g; Zinc = 0.374 [0.259, 0.557] mg/100g (wet weight);
