Estimates based on models
Preferred temperature (Ref.
123201): 8.4 - 11.2, mean 9.2 °C (based on 9 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.7 ±0.5 se; based on size and trophs of closest relatives
Generation time: 20.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (tm=12; tmax=50).
Fishing Vulnerability (Ref.
59153): High to very high vulnerability (68 of 100).
