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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (tm=2; Fec=200).
Fishing Vulnerability (Ref.
