The levels of lactate dehydrogenase, hydroxy butyric dehydrogenase, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, glutamate dehydrogenase, alkaline phosphatase and leucine amino peptidase were determined in the plasma of rainbow trout. The protein concentration and the amount of alkaline phosphatase were reduced in starving trout. Fed trout showed reduced lactate dehydrogenase activity. There was a significant correlation between the condition factor, most of the enzyme activities and the protein concentration. At 10 parts per thousand salinity the activities of alkaline phosphatase and leucine amino peptidase were significantly elevated, while lactate dehydrogenase activity was significantly decreased.
