Includes bibliographical references. "Video footage of Western Lake Erie's bottom was collected from 12 stations during a research cruise aboard the RV Hydra during August 1994. The purpose of the footage was to record zebra mussel infestation on the lake floor and to act as a tool, along with sidescan sonar imagery, for quantifying zebra mussel populations in the lake. The following report (1) explains the method used to quantify zebra mussel populations from the video footage and (2) lists the results of the zebra mussel quantification from the video footage collected in 1994"--Introduction, page 1. gccst Molluscs gccst Invasive species gccst Lakes Brown, Glenn R.
