Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00631 (0.00289 - 0.01377), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
