Estimates based on models

Preferred temperature (Ref. 123201): 5.9 - 14.4, mean 9.4 °C (based on 305 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00316 (0.00129 - 0.00773), b=3.18 (2.97 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).

Nutrients (Ref. 124155): Calcium = 37.7 [10.0, 151.4] mg/100g; Iron = 0.803 [0.280, 2.094] mg/100g; Protein = 2.18 [0.00, 5.97] %; Omega3 = 0.367 [0.137, 1.048] g/100g; Selenium = 17.4 [4.2, 60.5] μg/100g; VitaminA = 11.1 [2.2, 54.0] μg/100g; Zinc = 0.46 [0.23, 0.92] mg/100g (wet weight);
