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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Assuming Fec. <10; tm=1.8; K=0.3 (in captivity).).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Catégorie de prix (Ref. 80766): Medium.
