Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00621 - 0.02027), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Nível Trófico (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (25 of 100).
Nutrients (Ref.
124155): Calcium = 122 [49, 343] mg/100g; Iron = 2.64 [1.19, 6.24] mg/100g; Protein = 19 [17, 21] %; Omega3 = 0.431 [0.153, 1.295] g/100g; Selenium = 80.6 [29.5, 236.1] μg/100g; VitaminA = 11.3 [3.1, 40.2] μg/100g; Zinc = 2.1 [1.3, 3.3] mg/100g (wet weight);
