Estimates based on models
Preferred temperature (Ref.
123201): 1.3 - 2.5, mean 1.8 °C (based on 23 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00132 (0.00060 - 0.00289), b=3.46 (3.28 - 3.64), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.3 ±0.54 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Assuming tm=4; Fec = 2,770).
Fishing Vulnerability (Ref.
