Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.01274 - 0.01798), b=2.97 (2.92 - 3.02), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 2.6 ±0.2 se; based on diet studies.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (tm<1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Categoria de preço (Ref. 80766): Unknown.
