Abstract

The objectives of this study were to determine effects of Eurasian watermilfoil (Myriophyllum spicatum) removal on bluegill feeding habits relative to diet composition, size, and feeding selectivity. Data were collected from 2003 through 2007 in four Minnesota lakes during June and September using boat electrofishing. Two lakes received an herbicide application of Endothall 2, 4-D, whereas remaining lakes were untreated and used as a reference. Bluegill diet composition, diets relative to size, and feeding selectivity were unaffected by vegetation removal, but varied seasonally with macroinvertebrate availability. Therefore, removal of Eurasian watermilfoil had minimal effects on bluegill feeding habits.
