摘要:

This study includes results of stomach examinations of 5,253 burbot captured near various ports along the north shore of Lake Erie from May, 1946, to May, 1947. Variations in major food items in relation to method of capture, season, locality, and the length of the burbot are examined. The major food items were evaluated by volume, number of items consumed, and the number of stomachs containing each item. Each criterion of abundance assisted in the determination of the role of the burbot in the food relationship of fish in the lake. Fish and invertebrates, largely Percidae and crustaceans, constituted the major part of the burbot's diet. Until its third year of life, the burbot feeds extensively on invertebrates, but from its third to fifth years, fish become the predominant food. Larger burbot had more food in their stomachs than did the smaller burbot and they consumed larger fish rather than larger numbers of fish.
