	year = {1971},
	note = {The critical transformation from parr to smolts enables young salmon to tolerate and move into salt water.  This doctoral dissertation is a study of that metamorphosis.  The author studied the effects of constant and variable photoperiods and variations in water temperature.  Fish were released into Lint Creek and Crooked Creek and later recaptured.  Possible changes in thyroid activity were investigated. Major professor was James D. Hall.},
