Estimates based on models

Preferred temperature (Ref. 123201): 9.7 - 18.4, mean 13.4 °C (based on 113 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00168 - 0.00747), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.62 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec=21-22).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).
