Estimates based on models
Preferred temperature (Ref.
123201): 0.4 - 5.2, mean 3.2 °C (based on 91 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00458 - 0.01316), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
栄養段階 (Ref.
69278): 3.3 ±0.42 se; based on food items.
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 低い, 4.5年~14年の倍増期間の最小個体群 (K=0.14 (very tentative estimate)).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100).
