The aim of present study was the evaluation of the antioxidant enzyme’s activity and activity of anaerobic glycolysis enzymes under gradual temperature increase in Baikal amphipods species Eulimnogammarus marituji (Baz., 1945), E. maackii (Gerstf, 1858) and  Gmelinoides fasciatus (Stebb., 1899). In all species under gradual temperature increase exposition elevation of peroxidase’ activity was observed. Activities of catalase’, glutathione S – transferase’ and lactate dehydrogenase’ activity in  E. marituji and E. maacki were differed from G. fasciatus. It was proposed that changes in the antioxidant enzyme’s activity and activity of anaerobic glycolysis enzymes in Baikal amphipods may contribute to increasing of glycolytic processes functional efficiency and keeping of energetic homeostasis in endemic organisms.

Key words:   Amphipods; catalase; glutathione S – transferase; lactate dehydrogenase; peroxidase
