Estimates based on models

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

Bayesian length-weight: a=0.01000 (0.00517 - 0.01933), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 2.7 ±0.22 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;).

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

Catégorie de prix (Ref. 80766): Unknown.
