The objective of the study was to determine the inter-specific differences in the content of Mn, Cu, Zn, Fe, Ca, Mg, Na, and K, as well as in fatty acids in muscles of rainbow trout, carp, and salmon purchased at a market in the city of Olsztyn (Poland). The carp fish was characterized by the highest content of Mn, Fe, and Ca. also it was found that the carp was a rich source of Zn, and the significant differences were found only if compared to the salmon. As for the other elements, no significant interspecific differences were found. In the lipids contained in the muscles of rainbow trout examined, the highest content of saturated fatty acids (26,79 percent) was determined. The highest amount of monoenoic acids was reported in lipids in the muscle tissue of carp (51,45 percent). Among the saturated fatty acids, the palmitic acid was a predominant fatty acid whereas the monoenoic fatty acids were represented by the oleic acid
