1. 1. The protein synthesis stimulating activity of the cytosolic fraction of white muscle tissue taken from rainbow trout after exposure to various experimental conditions was tested. 2. 2. Foor deprivation reduced the in vitro protein synthesis stimulating activity in the cytosolic fraction. 3. 3. Protein synthesis stimulating activity of the cytosolic fraction reaches a new steady state within two weeks after the food ration has been changed. 4. 4. Protein synthesis stimulating activity of the cytosolic fraction increases appreciably after the fish have been adapted to diluted sea-water with a salinity of 15% for 34 days.
