Estimates based on models
Preferred temperature (Ref.
123201): 24.5 - 29, mean 27.5 °C (based on 294 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 2.6 ( 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=4; K=0.428; Tmax=25).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
