Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
