Estimates based on models

Preferred temperature (Ref. 115969): 21.5 - 26.9, mean 24.7 (based on 164 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00363 (0.00147 - 0.00899), b=3.07 (2.86 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.2 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec is assumed to be <10).

Fishing Vulnerability (Ref. 59153): High vulnerability (55 of 100).

Catégorie de prix (Ref. 80766): Unknown.
