Estimates based on models
Preferred temperature (Ref.
123201): -1.4 - 5.9, mean -0.3 °C (based on 868 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00505 - 0.02860), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.3 se; based on diet studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=4,000-12,000).
Fishing Vulnerability (Ref.
