Effects of nickel, administered as aqueous solutions of nickel (II) nitrate (V), on European catfish, Silurus glanis L. were studied. The fish were at first exposed for 24 h (short term exposure). The results obtained during the short-term exposure were used to determine the amount of nickel to be used during a 60-d (long-term) exposure. A significant effect of nickel on the distribution of zinc and copper in the fish blood and organs was found. The changes may have produced disturbed metabolism of the microelements under study dur ing biochemical and energetic processes in the fish. Neither the shortnor the longcterm exposure of the fish to nickel re sulted in a significant accumuiation of the metal in muscles; nor were changes in the microelement concentration in mus cles observed.
