Estimates based on models
Preferred temperature (Ref.
123201): 1.1 - 5.9, mean 3.7 °C (based on 205 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00652 - 0.01607), b=3.10 (2.97 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.3 ±0.3 se; based on diet studies.
Generation time: 36.6 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tmax=157; k=0.04).
Prior r = 0.02, 95% CL = 0.01 - 0.04, Based on 1 stock assessment.
Fishing Vulnerability (Ref.
