Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 28.7, mean 27.7 (based on 550 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00398 (0.00251 - 0.00631), b=3.07 (2.94 - 3.20), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.1 se; based on diet studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.24-0.98; tm=2;).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Catégorie de prix (Ref. 80766): Very high.
