Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 8.9, mean 6.7 (based on 174 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6289 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00195 (0.00083 - 0.00458), b=3.15 (2.95 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.46 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming Fec <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (84 of 100).
