Estimates based on models

Preferred temperature (Ref. 115969): 17.5 - 23.6, mean 20.2 (based on 66 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.0 ±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 (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).
