Estimates based on models
Preferred temperature (Ref.
123201): -1.9 - 1.4, mean -0.2 °C (based on 1465 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Generation time: 9.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (K=0.1; Fec=40; tm=5; tmax=14).
Fishing Vulnerability (Ref.
59153): High vulnerability (58 of 100).
