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=0.00891 (0.00585 - 0.01358), b=3.03 (2.91 - 3.15), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Resiliência (Ref.
120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.19-0.63(?); tmax=6; Fec > 10,000).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (45 of 100).
