Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.4   ±0.54 se; based on food items.
Resiliência (Ref. 120179):  Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Fec=2).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (43 of 100).
