The study described was aimed at determining levels of selected macro– (Mg) and microelements (Ni, Fe, Cu, Zn) as well as those of heavy metals (Cd) in tissues and organs of the carp farmed in Western Pomerania, with a particular reference to fish-rearing facilities in River Odra. The study involved 5-month-old carp acquired from the research station of the Agricultural University of Szczecin. The levels of the metals were determined and compared with the data available in the literature, a particular attention being paid to values reported from the fish reared in the Odra. The results showed the contents of the elements studied to be within physiological reference ranges of cyprinids.
