Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02455 (0.01209 - 0.04986), b=2.96 (2.79 - 3.13), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 4.1 ±0.60 se; based on food items.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.18-0.28).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Categoria de preço (Ref. 80766): Very high.
