Rensselaer Effort To 'Pull Mussels' At Lake George Looks Promising

The number of zebra mussels found in Lake George has declined dramatically since last year, when Rensselaer Polytechnic Institute researchers and volunteers began manually pulling the troublesome mollusks from the water. The time-consuming, labor-intensive effort appears to be paying off.

TROY, N.Y. - The number of zebra mussels found in Lake George has declined dramatically since last year, when Rensselaer Polytechnic Institute researchers and volunteers began manually pulling the troublesome mollusks from the water.

The time-consuming, labor-intensive effort appears to be paying off. In the spring of last year, shortly after the first adult zebra mussels were discovered in the popular recreational lake, divers collected more than 19,000 of them. Last fall's harvest netted 1,800. Since April of this year, however, divers have pulled only 352 mussels.

"Of course, I can't guarantee that all of the zebra mussels are gone from Lake George. That would be premature. But I am optimistic, based on the numbers, that we got most of them at this site," said Sandra Nierzwicki-Bauer, professor of biology at Rensselaer and director of its Darrin Fresh Water Institute.

More good news is the size of the mussels pulled this year: All are too large to have been born in 2000 or 2001. Last year's harvest seems to have culled the mussels before they reproduced, and they have not been found elsewhere in the lake.

Zebra mussel larvae were first found in Lake George in 1995, but researchers believed that lake chemistry—probably low calcium and pH levels—kept them from maturing. A culvert carrying storm runoff with high calcium levels may account for the proliferation of adult mussels at the site on the southeastern shore.

The mussels are a European invader already well established in Lake Champlain and the Hudson River. They can choke drinking-water pumps, foul outboard motors, and deter tourists. The mussels may have entered Lake George while attached to boats, boat trailers, anchors, bait buckets, or on equipment used in the construction of a nearby boardwalk.

The Darrin Fresh Water Institute is a member of the Zebra Mussel Task Force that includes the New York State Department of Environmental Conservation, the Lake George Park Commission, the Lake George Association, the Fund for Lake George, and other agencies.

The task force has issued pamphlets and mussel identification kits as part of its campaign to encourage boaters to clean their boats and other equipment before putting them in the water. In May, the State of New York appropriated $20,000 to pay for the installation of two boat-washing stations at Lake George.

"What we hope to do is educate the public about the problems posed by zebra mussels. They're more than a nuisance. By taking a little extra time to inspect their boats and clean them, people can play a major role in preventing the spread of zebra mussels to the Queen of American Lakes," Nierzwicki-Bauer said.

Rensselaer Polytechnic Institute, founded in 1824, is the nation's oldest technological university. The school offers degrees in engineering, the sciences, information technology, architecture, management, and the humanities and social sciences. Institute programs serve undergraduates, graduate students, and working professionals around the world.

Rensselaer faculty are known for pre-eminence in research conducted in a wide range of research centers that are characterized by strong industry partnerships. The Institute is especially well known for its success in the transfer of technology from the laboratory to the marketplace so that new discoveries and inventions benefit human life, protect the environment, and strengthen economic development.
