Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.3 ±0.2 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 (Assuming Fec<1000).
Fishing Vulnerability (Ref.
