Abstract
Until recently, very little quantitative work has been done on the daily or short term movements of fresh water fish. Investigations by Hasler and Bardach (1949) have verified the existence of a diurnal movement of the yellow perch (Perca flavescens Mitchill) in Lake Mendota, Wisconsin. The present paper reports the results obtained from an investigation of the movements of yellow perch in Lake Okoboji, Dickinson County, Iowa. The investigation was undertaken in the summer of 1950 at the Iowa Lakeside Laboratory, and was primarily an attempt to ascertain: 1) do these fish undergo a diurnal movement, 2) is there a pattern to this movement, and 3) if they move regularly, what is the reason for this movement. The methods employed in this investigation were patterned after those used on Lake Mendota. The authors wish to thank Dr. John E. Bardach of the Iowa Lakeside Laboratory staff, for his guidance and assistance in this undertaking.
