Estimates based on models
Preferred temperature (Ref.
123201): 4.9 - 24.4, mean 9.3 °C (based on 71 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01026 - 0.05115), b=2.89 (2.72 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.66 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K=0.6).
Fishing Vulnerability (Ref.
59153): Low vulnerability (24 of 100).
Climate Vulnerability (Ref.
