Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00389 - 0.01621), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.9 ±0.37 se; based on food items.
Generation time: 4.4 ( 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 (tm=5; tmax=12; Fec=40; K=0.3).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
