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=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.8 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Fec assumed to be <10).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (27 of 100).
