The exotic alewife (Alosa pseudoharengus) has become exceedingly abundant in Lake Michigan. During May-August, they migrate to inshore waters to spawn and may provide an abundant food supply for the inshore warm-water piscivorous fishes. I examined stomach contents of 405 northern pike (Esox lucius), 112 smallmouth bass (Micropterus dolomieui), 103 walleye (Stizostedion vitreum vitreum), 43 burbot (Lota lota) and 29 bowfin (Amia calva) from Little Bay de Noc in Lake Michigan, during April-October of 1966–68 to determine their food habits when alewives were abundant and when alewives were scarce.
