ABSTRACT

The impact of elevated concentration (2 and 5 MPC) of Fe3+ ions in water on content of nucleic acids and proteins in liver and muscles of carp (Cyprinus carpio L.) and pike (Esox lucius L.) was studied. Metabolic activity of the nucleic acids and proteins in fishes' tissues under experimental conditions was shown to change. Mechanisms of biochemical adaptation of fishes to the toxic impact of heavy metals and role of proteins and nucleic acids in this process are considered.
