Perch (Perca fluviatilis) netted in the Gdańsk Gulf in 1987 and 1989, was searched for Cu, Mn, Zn, Fe, Ca, Mg, Na, and K content in the muscular tissue and liver, using atomic absorption or emission spectrometry. Average concentrations (mg/kg wet weight), were found as follows: Cu - 0.26, Mn - 0.31, Zn - 7.7, Fe - 2.9, Mg - 290, Ca - 390, Na - 1000, adn K - 5700. As the body weight of perch increased, Mn, Fe, Zn, and Ca concentrations in the muscular tissue and Mn content in the liver, were observed to decrease. On the other hand, Cu, Na, K, and Mg concentrations in muscles and Cu, Fe, and Zn levels in the liver, remained constant. A positive intermetallic linear correlation was show for the following pairs of metals: Cu-Fe, Mn-Fe, Mn-Zn, and Fe-Zn.
