Estimates based on models

Preferred temperature (Ref. 115969): 1.9 - 8.7, mean 6.7 (based on 239 cells).

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

Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (77 of 100).
