Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.2 ±0.25 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec=2,350; tmax likely > 15 years).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Categoria de preço (Ref. 80766): Unknown.
