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=0.00282 (0.00131 - 0.00604), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 4.5 ±0.80 se; based on food items.
Generation time: 10.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary low fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (47 of 100).
