"During November and December 1993, navigational buoys (n = 252) retrieved from Canadian waters (Lake Superior downstream to the outlet of Lake Ontario) were examined for the presence of attached Zebra Mussels (Dreissena polymorpha) and Quagga Mussels (D. bugensis). Attached mussels were found on 136 buoys, or 54.0% of the total. Mussels were absent from all buoys examined on Lake Superior and the North Channel of Georgian Bay. Mussels were attached to 16% of buoys in Georgian Bay and 40% in Lake Huron. Mussels were attached to most buoys from Lake St. Clair, the Detroit River, and Lake Erie. All of the buoys from Lake Ontario had attached mussels in 1993, as compared to only three buoys in December 1992. As in 1992, Quagga Mussels were present only on buoys east of Point Pelee in Lake Erie. They were present on all buoys with attached mussels from the central and eastern basins of Lake Erie. Quagga Mussels represented up to 100% of the attached mussels on buoys near Nanticoke, eastern Lake Erie. Quagga Mussels were present on 75% of the buoys from Lake Ontario; however, no Quagga Mussels were present on buoys in the Bay of Quinte during 1993"--Abstract, page iv.
