The aim of present study was the evaluation of antioxidant (peroxidase, catalase, glutathione S transferase)  and  anaerobic  glycolysis  (lactate  dehydrogenase)  enzymes  activity  under  thermal gradient in  Palearctic species Lymnaea stagnalis  (Linnaeus,1758). Activity of peroxidase,  lactate dehydrogenase  and  glutathione  S-transferase elevated  in  L.  stagnalis  under  thermal  exposure. Opposite to this, activity of catalase decreased in same condition. We demonstrated antioxidant nd  anaerobic  glycolysis  enzymes  participation  in  adaptation  mechanisms  to  environmental hanges in gastropods L. stagnalis.

Key words:  Gastropods, glutathione S – transferase, catalase, lactate dehydrogenase, peroxidase
