Key to Families


This manual for the identification of larval fishes of the Great Lakes basin with emphasis on the Lake Michigan drainage treats 24 families and 148 species. In addition to a key to the families, keys are constructed for selected species within some families. Species accounts include descriptions of adult ecology, reproductive biology, diagnostic characters and meristics. A description of the egg is given, as are morphometric, morphological and pigmentation characteristics of yolk-sac larvae, larvae and juveniles. Illustrations of yolk sac larvae, larvae and juveniles have been included where possible and informative.
