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=0.00813 (0.00354 - 0.01865), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.4 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 (tm=0.5-1.5; Fec=20-40; assuming multiple pregnancies per year).

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