Estimates based on models
Preferred temperature (Ref.
123201): 1.4 - 4.8, mean 3.5 °C (based on 33 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.8 ±0.0 se; based on diet studies.
Generation time: 11.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (tm = 4-7).
Fishing Vulnerability (Ref.
