The analysis of plankton tows for May, 1961, and May, 1962, showed four species of diatoms, Melosira binderana, M. ambigua, Fragilaria capucina and F. crotonensis to be dominant. The analysis of the intestinal tract of the walleye fry showed these four species to be dominant in the fry up to 9 mm. Those fry above 9 mm contained zooplankton as well as species of these diatoms. This preliminary study indicates a change in food habits of the walleye fry at the 9-mm stage.
