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=0.00372 (0.00145 - 0.00950), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
