Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.2 ±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).
