Myofibrillar ATPase activity was measured in the epaxial musculature of rainbow trout acclimated to 5 and 21.°C, and goldfish acclimated to 5 and 30°C. The acclimated goldfish showed considerable differences in the specific activity and thermostability of this enzyme. However, such alterations were not apparent in the acclimated trout. The evolutionary implications of these findings are discussed.
