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=0.00513 (0.00255 - 0.01032), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Nivel trófico (Ref.
69278): 3.3 ±0.45 se; based on food items.
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Fec=16,500 (landlocked population)).
Fishing Vulnerability (Ref.
