Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00223 - 0.00678), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on diet studies.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (tm=1; Fec = 1,033; post-spawning mortality almost 100%).

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

Catégorie de prix (Ref. 80766): Low.
