Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00344 - 0.01054), b=3.22 (3.07 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.3 ±0.3 se; based on diet studies.
Generation time: 4.6 (2.9 - 5.8) years. Estimated as median ln(3)/K based on 18
growth studies.
Résilience (Ref.
120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=3; k=0.22).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (42 of 100).
