Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.01564 - 0.02217), b=2.98 (2.93 - 3.03), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nível Trófico (Ref.
69278): 2.2 ±0.12 se; based on food items.
Resiliência (Ref.
120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.19-0.43; Tmax=5).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
Nutrients (Ref.
124155): Calcium = 16.9 [6.0, 99.1] mg/100g; Iron = 2.67 [0.66, 6.68] mg/100g; Protein = 19 [17, 21] %; Omega3 = 0.611 [0.246, 1.507] g/100g; Selenium = 51.2 [20.3, 112.3] μg/100g; VitaminA = 13.4 [4.4, 38.7] μg/100g; Zinc = 1.14 [0.81, 1.66] mg/100g (wet weight);
