Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.2, mean 28.2 °C (based on 1182 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01318 (0.00799 - 0.02176), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.0 ±0.33 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (K=0.90-1.75).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Catégorie de prix (Ref. 80766): High.
