Estimates based on models
Preferred temperature (Ref.
123201): 5.4 - 19.1, mean 17.2 °C (based on 50 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00636 - 0.01435), b=3.13 (3.01 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.2 se; based on diet studies.
Generation time: 16.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tm=14-24; K=0.02).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100).
