Estimates based on models
Preferred temperature (Ref.
123201): 28 - 29.3, mean 28.9 °C (based on 733 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00480 - 0.00690), b=3.14 (3.09 - 3.19), in cm total length, based on LWR estimates for this species (Ref.
93245).
Niveau trophique (Ref.
69278): 4.0 ±0.64 se; based on food items.
Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (K=0.65).
Fishing Vulnerability (Ref.
