Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00167 - 0.00864), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
