Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 26.3, mean 25.3 (based on 11 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01778 (0.00963 - 0.03285), b=3.03 (2.88 - 3.18), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.80 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Categoria de preço (Ref. 80766): Very high.
