Estimates based on models

Preferred temperature (Ref. 123201): 5.6 - 10.5, mean 6.5 °C (based on 15 cells).

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

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), 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): Low to moderate vulnerability (35 of 100).
