- Abstract
The effect of seasonal changes on the activity of intestinal alkaline phosphatase was evaluated in two types of fish grown in the Kurshskii bay of the Baltic sea. With the pike perch, Lucioperka lucioperka, higher enzyme activity and optimal temperature of activity were observed in the summer compared to winter, whereas with the bream, Abramis brama, essentially no difference in enzyme activity and in optimal temperature of activity was found between the two seasons. In both fish, the thermal stability of the enzyme and the activation energy of enzyme activity decreased in winter. The different biological nature of the two fish appears to be reflected in the response of the intestinal alkaline phosphatase to seasonal changes.
