Estimates based on models

Preferred temperature (Ref. 115969): 17.7 - 26.6, mean 22.5 (based on 96 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Categoria de preço (Ref. 80766): Medium.
