Estimates based on models

Preferred temperature (Ref. 115969): 18.6 - 27.9, mean 25.7 (based on 120 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.67 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming tmax>10).

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

Climate Vulnerability (Ref. 125649): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): High.
