Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.4 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).
