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

Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resiliencia (Ref. 120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (86 of 100).
