Includes bibliographical references (pages 24-25). "Sediment samples collected from the sediment-water interface from Lake Erie in 1975 indicate the presence of a few live shelled invertebrates (ostracodes). Of the 26 species identified only one, Candona caudata, can be considered as successful today in Lake Erie. Cytherissa lacustris and Candona subtriangulata, primarily recovered as empty shells in this study, indicate that these species have become extinct because of a chemical and/or physical change some time during the last 100 years in Lake Erie. Dissolved oxygen stress patterns verify the oxygen depletion pattern noted by Burns and Ross (1972) and indicate its existence for time in the central basin"--Abstract, page 1.
