The author performed the histological analysis of the oocytes of golden (Chinese) carp, Carassius auratus gibelio (Bloch). Its habitat was radioactive-contaminated Belarusian reservoirs within Chernobyl zone. The obtained results revealed that the oocytes underwent some degenerative alterations such as irregular nucleus shape and karyolysis. That was witnessed by examination of the fish of Perstok Lake where water was characterized by the high level of radioactive contamination. It was shown that the alterations were connected with the high level of natural habitat contamination. These alterations were also caused by the high content of radionuclides in fish tissuies and organs
