50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00288 - 0.01384), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 4.5 ±0.80 se; based on food items.
Resiliência (Ref.
120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
