Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00675 - 0.02347), b=2.94 (2.79 - 3.09), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec = 15).

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