ESTIMATION OF LIPID PEROXIDATION IN TISSUES OF FISH FROM LAKES OF THE KENTI RIVER SYSTEM, REPUBLIC OF KARELIA
Lipid peroxidation in tissues of pike Esox lucius Linnaeus, 1758 and roach Rutilus ruti‑ lus (Linnaeus, 1758) from Lake Kostomukshskoe (storing tailings from the Kostomuksha ore mining and processing enterprise) was found to be more intensive than in fish living downstream the Kenti River.
