Estimates based on models
Preferred temperature (Ref.
123201): 2.2 - 5.6, mean 3.6 °C (based on 1847 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5645 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.5 ±0.50 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 tmax>10).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100).
