Estimates based on models

Preferred temperature (Ref. 123201): 21.9 - 27.7, mean 24.3 °C (based on 24 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03090 (0.01359 - 0.07026), b=2.89 (2.70 - 3.08), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.45 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).

Catégorie de prix (Ref. 80766): High.
