Estimates based on models

Preferred temperature (Ref. 123201): 21.9 - 27.3, mean 25.8 °C (based on 50 cells).

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

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
