Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00554 - 0.01979), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Niveau trophique (Ref.
69278): 2.4 ±0.1 se; based on size and trophs of closest relatives
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Résilience (Ref.
120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=2; k=0.27; Tmax=7).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
