| Abstract | Rainbow smelt, Osmerus mordax Mitchill, in Lake Michigan originated from a planting in Crystal Lake, Mich., in 1912 (Van Oosten 1937). Since its introduction in Lake Michigan, the smelt has become abundant, serving as forage for larger,' predatory species (Wright 1968; Harney and Norden 1972) and sustaining a small seasonal sport and commercial fishery. There has been considerable controversy regarding the smelt's role as a piscivore. Food studies of smelt in Saginaw Bay, Lake Huron (Gordon 1961) and Lake Erie (Price 1963) have shown that smelt consumes fishes, but not the alewife, Alosa pseudoharengus. Recently, a fall collection of smelt revealed that it consumes young-of-the-year alewives (O'Gorman 1974). The food habits of Lake Michigan smelt have not been studied on a seasonal basis and little information exists concerning its food habits during the winter months. Also, feeding chronology has never been considered. The purpose of this study was to examine food habits ofsmelt during 6 mo representing all four seasons and to consider feeding chronology during two representative months. |
