Estimates based on models
Preferred temperature (Ref.
123201): -1.8 - 0.8, mean -1 °C (based on 410 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00296 - 0.01410), b=3.17 (2.97 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.70 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec > 10,000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (23 of 100).
