Introduction
The need for a publication to assist in the identification of larval fishes of the Great Lakes region has been documented. A workshop sponsored by the U.S. Fish and Wildlife Service national Power Plant Team in Ann Arbor during 1976 was convened to organize such a compendium.
The Great Lakes Region is unique in that 5 large connected bodies of freshwater, very different in trophic status, contain different combinations of one general fish fauna. Although there are published works dealing with the identification of adult fishes in the Great Lakes region only two current publications deal with larval fish identification in this region Drewry (1979) and Lippson (1976).
