Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00349 - 0.02862), b=3.09 (2.85 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Fec = 100-800).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
