The young flsh produced from these fish were reared at the laboratory until migration size, when they were marked by the renoval of the adipose fin and a ventral fin. The young fish were then transported back to Cultus Lake and migrated to sea. It was expected that the survivors would return from the sea this fall as adults. To date, no marked fish have been recorded from this experiment. II.

During the month contact was maintained with the Hanford Engineering Works, especially the personnel of the 146 Building. Chinook salmon eggs were transferred from the coast to the 146 Building to be used in continuation of the monitoring studies and for new exploratory studies. Mr. Wendell K.
