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=0.00501 (0.00202 - 0.01242), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.2 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100).
Nutrients (Ref.
124155): Calcium = 41 [19, 68] mg/100g; Iron = 0.45 [0.24, 0.80] mg/100g; Protein = 16.3 [14.0, 19.0] %; Omega3 = 0.809 [0.336, 1.839] g/100g; Selenium = 26.7 [10.8, 69.8] μg/100g; VitaminA = 18.7 [5.9, 59.2] μg/100g; Zinc = 0.784 [0.530, 1.194] mg/100g (wet weight);
