Estimates based on models

Preferred temperature (Ref. 115969): 20.6 - 28.4, mean 26.6 (based on 38 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00218 - 0.01003), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.2 ±0.74 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=5).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Medium.
