Estimates based on models
Preferred temperature (Ref.
123201): 3.7 - 13.2, mean 6.5 °C (based on 300 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.6 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 (46 of 100).
Nutrients (Ref.
124155): Calcium = 22.5 [12.7, 52.3] mg/100g; Iron = 0.415 [0.209, 0.860] mg/100g; Protein = 15.7 [13.2, 18.1] %; Omega3 = 0.282 [0.140, 0.581] g/100g; Selenium = 31.4 [12.0, 77.2] μg/100g; VitaminA = 7.14 [1.37, 35.40] μg/100g; Zinc = 0.463 [0.287, 0.731] mg/100g (wet weight);
