Background:Due to excellent nutritional properties offish andfish products, dietitians recommend their largershare in the diet, for both the prevention and treatment of diet-related diseases. In this context particular at-tention should be given tofish eggs (roe). The aim of the study was to compare the content of selected mineralsand trace elements in the roe and muscle tissue of aquaculture-reared rainbow trout. Moreover, the extent towhich an edible portion of 100 g offish product (roe orfillet) satisfies the requirements for these elements inadult consumers (women and men) and children was determined.Methods:The research material was represented by 20 farmed rainbow trout females (Oncorhynchus mykiss). Inmuscle tissue and roe the proximate composition, energy value, and nutritional quality index were examined.Concentrations of K, Na, Ca, Mg, Zn, Fe, Mn and Cu were determined byflame atomic absorption spectrometryanalysis. The levels of minerals and trace elements infish products were used to calculate the percentages of therecommended dietary reference values for adults and children in portion of 100 g.Results:The roe had higher content of 7 elements including, Zn (29.40 ± 1.38, 27.74–30.91 mg/kg), Mn(1.66 ± 0.08, 1.55–1.73 mg/kg), Fe (11.17 ± 0.35, 10.75–11.60 mg/kg), Cu (1.24 ± 0.04, 1.21–1.30 mg/kg),Ca (546.90 ± 23.68, 522.02–578.96 mg/kg), Mg (546.97 ± 23.68, 522.02–578.96 mg/kg), Na(403.61 ± 5.53, 397.29–407.57 mg/kg) compared to muscle tissue, respectively, Zn (2.73 ± 0.97,0.94–3.77 mg/kg, Mn (0.22 ± 0.10, 0.14–0.46 mg/kg), Fe (2.19 ± 1.44, 1.02–5.50 mg/kg), Cu (0.24 ± 0.06,0.17–0.36 mg/kg), Ca (164.07 ± 71.72, 93.24–306.32 mg/kg), Mg (240.00 ± 73.37, 127.92–316.41 mg/kg),Na (273.37 ± 99.65, 183.93–524.41 mg/kg). In turn, the muscle tissue contained 3 times as much K(5159.87 ± 974.70, 4004.63–6343.91 mg/kg) as the roe (1713.65 ± 58.68, 1643.97–1764.14 mg/kg). Theroe covered the recommended nutrition standards (population reference intake, PRI and adequate intake, AI) toa greater extent than thefillet for all analysed trace elements and minerals except K. For children, the con-tribution of roe to the reference intake of such elements as Mg, Zn, Fe, Mn and Cu was particularly high.Therefore the roe should be considered as a source of Mg for all consumer groups, and as high in Zn for womenand children. The suggested portion offillet and roe provided only 2–3 % of the daily requirement for Na.Conclusions:Despite the differences found, both roe andfillet from rainbow trout are a good source of analysedelements. The results indicate the need to continue research in order to determine the influence of other factorson the content of minerals and trace elements in roe and the possibility of using gonads to enrich other foodproducts with elements
