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=0.00550 (0.00248 - 0.01216), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.3 ±0.2 se; based on size and trophs of closest relatives
Generation time: 5.6 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Résilience (Ref.
120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.19-0.29).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (32 of 100).
