Other Monitoring Efforts

From September 17, 1990 (update #4)

* Samples from eight water intakes from Lake Huron to the St. Lawrence River are being examined weekly for the presence of zebra mussel veligers in a pilot study by Gordon Hopkins of the Limnology Section, Water Resources Branch, Ontario Ministry of the Environment. In monthly summaries for May through July, Hopkins reported that veligers have been consistently found only in samples from two Lake Erie water intakes.

* A single mussel on a shipwreck near Alpena, Mich., was the only confirmed sighting resulting from plankton tows and scuba dives for zebra mussels from western Lake Huron to northern Green Bay, Lake Michigan, during early July by Doug Hunter of Oakland University, Rochester, Mich.

* Monitoring of the Niagara River and its adjoining canal systems, including the New York barge canal system, has turned up adult zebra mussels in the canal system as far east as the Genesee River near Rochester, according to Dale Miklas of Acres International Corp., Amherst, N.Y.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
