1.  ATPase activities in gills of yearling coho salmon were monitored from February to October.
2.  Na+, K+–activated ATPase activity increased during the last 2 weeks of March and remained constant until July, when a decrease was observed.
3.  Na+, K+–activated ATPase began to increase 3 to 4 days after coho salmon were placed in salt water and continued to increase for 30 to 35 days.  Mg2+–dependent ATPase decreased during this same period of time.
4.  Dietary sodium chloride caused an increase in Na+, K+–ATPase and a decrease in Mg2+–dependent ATPase activity.
