Estimates based on models
Preferred temperature (Ref.
123201): 0.4 - 5.9, mean 2.8 °C (based on 418 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00381 - 0.01046), b=3.04 (2.89 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.35 se; based on food items.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (tm=5-6; tmax=17; K=0.13-0.17; Fec=6,100-72,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (25 of 100).
