Estimates based on models
Preferred temperature (Ref.
123201): 14.3 - 19.4, mean 16.3 °C (based on 288 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00440 - 0.01371), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Niveau trophique (Ref.
69278): 3.7 ±0.59 se; based on food items.
Generation time: 5.2 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Résilience (Ref.
120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming fecundity<100).
Fishing Vulnerability (Ref.
