Estimates based on models
Preferred temperature (Ref.
123201): -1.4 - 1.3, mean 0.5 °C (based on 43 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00135 (0.00106 - 0.00172), b=3.50 (3.43 - 3.57), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.62 se; based on food items.
Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<5).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (51 of 100).
Climate Vulnerability (Ref.
125649): High to very high vulnerability (68 of 100).
