Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00605 - 0.03300), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.2 ±0.39 se; based on food items.
Generation time: 6.5 ( 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 (K=0.17).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100).
Nutrients (Ref.
124155): Calcium = 84.4 [45.8, 169.8] mg/100g; Iron = 1.3 [0.8, 2.2] mg/100g; Protein = 17.2 [16.1, 18.2] %; Omega3 = 0.397 [0.156, 1.003] g/100g; Selenium = 70.8 [31.9, 148.7] μg/100g; VitaminA = 28.2 [10.2, 70.6] μg/100g; Zinc = 1.45 [0.97, 2.05] mg/100g (wet weight);
