Estimates based on models

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

Bayesian length-weight: a=0.00676 (0.00301 - 0.01516), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tmax=2; Fec=23-44).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
