Estimates based on models

Preferred temperature (Ref. 123201): 11.5 - 19.6, mean 16 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
Nutrients (Ref. 124155):  Calcium = 34.1 [4.9, 187.5] mg/100g; Iron = 0.864 [0.237, 2.666] mg/100g; Protein = 18.2 [15.1, 21.3] %; Omega3 = 0.215 [0.094, 0.467] g/100g; Selenium = 20.1 [5.8, 58.5] μg/100g; VitaminA = 19.8 [6.9, 56.4] μg/100g; Zinc = 0.594 [0.281, 1.116] mg/100g (wet weight);
