Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00456 - 0.02295), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  2.8   ±0.27 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (tm<1; multiple spawning per year; Fec=100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Categoria de preço (Ref. 80766):   Unknown.
