Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00486 - 0.01299), b=2.95 (2.82 - 3.08), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 se; based on diet studies.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=1.20).
Fishing Vulnerability (Ref.
59153): Low vulnerability (12 of 100).
Nutrients (Ref.
124155): Calcium = 284 [110, 741] mg/100g; Iron = 2.99 [1.45, 7.03] mg/100g; Protein = 18.9 [16.8, 21.2] %; Omega3 = 0.609 [0.218, 1.751] g/100g; Selenium = 47.1 [17.8, 146.4] μg/100g; VitaminA = 42.2 [15.4, 115.9] μg/100g; Zinc = 2.88 [1.87, 4.31] mg/100g (wet weight);
