Zebra Mussels at Cayuga Lake Zebra mussels, Dreissena polymorpha, are small, fingernail-sized, freshwater mollusks accidentally introduced to North America via ballast water from a transoceanic vessel.

Since their introduction in the mid 1980s, they have spread rapidly to all of the Great Lakes and an increasing number of inland waterways in the United States and Canada.

This invasive species represents what happens when an invasive species takes hold in a area, as I have watched the progress of this species since the mid 1980's. 

Now many of our lakes have been redefined by the Zebra Mussel, their ecology forever changed.

Zebra Mussels Discussions

Rochester area has been trying to deal with the spread of Zebra Mussels for a long time and the battle is symptomatic of how difficult these large invasive species outbreaks are to curb, even when you know they are coming.

  • Solving Invasive Problems This story about VHS describes perfectly how difficult it is going to be to curb the problem of invasive species and disease in the Great Lakes because ultimately without public support all the regulations and laws in the world won’t stop this kind of disease spread. Like the spread of Zebra Mussels and even HIV, it only takes a single carrier to infect another lake or person. Prevention, making sure that diseases like VHS don’t get into our waters seems to be the best solution and many communities are working on that—though again single communities, or in the case of the Great Lakes even a single state or country will not stop another state of country with lax laws from invasive species spreading.  more...

Over the years attempts at combating the Zebra Mussel problem has been reflected in the news.


  • Zebra, quagga mussels trump pollution as change agents in lake erie Over the last half century, Lake Erie has been known for its level of pollution and its population of invasive species. Of the two, the invasive species seems to have had the greater effect on the lake's zoobenthic community. That community—creatures living on, near, or below the bottom of the lake—is "fundamentally changed from its past," according to a paper published online in the current journal of the Journal of Great Lakes Research. Lyubov Burlakova, who works with the Great Lakes Center at SUNY Buffalo State, is the first author. The coauthors are Alexander Y. Karatayev, director of the center; Christopher Pennuto, a research associate with the center and biology professor at Buffalo State; and Christine Mayer, associate professor of ecology at the University of Toledo. "The story of Lake Erie shows how profoundly human activity can affect an ecosystem," said Burlakova. She traces that activity as far back as the early 1800s, when people cut down forests and built sawmills and dams. In 1918, the first report documenting the deterioration of water quality was published by the International Joint Commission. (July 16, 2014) Phys.org [more on Zebra Mussels in our area]
  • Pesticide experiment raises hopes of killing zebra mussels Scientists for the first time in Wisconsin plan to use a bacteria to kill zebra mussels — in this instance, in a Florence County lake. Researchers with the U.S. Geological Survey want to apply the biological pesticide next month to sections of Keyes Lake in the hope of killing off zebra mussels that have attached themselves to native mussel beds. If experiments prove successful, the treatment could one day be a tool to control the spread of destructive zebra and quagga mussels, both invasive species. Zebra mussels were discovered in the Great Lakes in the mid-1980s, and turned up in inland Wisconsin lakes in 1994. They can now be found in 163 lakes and rivers in the state, according to the state Department of Natural Resources. Quagga mussels are in the Great Lakes, but have not yet invaded inland lakes of Wisconsin. The pair of tiny, sharp-shelled species devour plankton, disrupting ecosystems. They proliferate in areas by the tens of thousands and push out native species, clog water intake systems and play a role in spurring algae blooms.

  • Zebra mussel-killing bacteria could help native species in the Great Lakes A treatment that kills zebra and quagga mussels could soon be available for use in lakes and rivers. It’s very effective and safe. But it is not likely to undo much of the ecological damage done to Michigan waters by invasive mussels.

  • Science Takes On a Silent Invader Since they arrived in the Great Lakes in the 1980s, two species of mussels the size of pistachios have spread to hundreds of lakes and rivers in 34 states and have done vast economic and ecological damage. These silent invaders, the quagga and zebramussels, have disrupted ecosystems by devouring phytoplankton, the foundation of the aquatic food web, and have clogged the water intakes and pipes of cities and towns, power plants, factories and even irrigated golf courses. Now the mussels may have met their match: Daniel P. Molloy, an emeritus biologist at the New York State Museum in Albany and a self-described “Bronx boy who became fascinated by things living in water.” (February 24, 2014) International New York Times [more on Zebra Mussels and Invasive Species in our area]
  • Grand Valley Study: Zebra Mussels, Algae Blooms Tied MUSKEGON (WWJ) – Researchers at Grand Valley State University’s Annis Water Resources Institute are finding that harmful algae blooms in two West Michigan lakes are linked to the water-clarifying action of the invasive species zebra mussels. Postdoctoral researcher Geraldine Nogaro and AWRI director Alan Steinman studied the impact that invasive zebra mussels and native chironomid larvae have on nutrient releases in Muskegon Lake and Bear Lake. While studying the mussels, Nogaro and Steinman noted that filter feeding and excretion activity by invasive mussels stimulated nutrient releases in the water column. The other subject of the research was the impact of native chironomids, which are insect larvae that live in the sediment on the lake bottoms. The researchers found the chironomids burrowed into the sediment, moving water and oxygen into the sediment and increased the levels of nutrients released into the sediment porewater and water column.

  • Study Shows Zebra Mussels Resistant To Deadly Toxin Already known as a menace around the Great Lakes, with a “Tribble-like” capacity to reproduce, zebra musselsare unaffected by a deadly toxin that wipes out other freshwater mussels, according to a new study in the Journal of Proteome Research. When blue-green algae flourish in freshwater, they release a toxin that stresses and weakens most freshwater mussels, but not zebra mussels. Study researchers said the finding is bad news for biodiversity and for water-related industries that consider the prolific species to be a menace. According to the scientists, zebra mussels’ ambivalence to the toxins allows them to thrive in their watery ecosystem better than other freshwater mussels – to the point where they overrun their competition. “Zebra mussels live in large colonies in the Great Lakes in the United States, and they are a huge problem,” saidClaudia Wiegand, an associate professor of environmental stress physiology and aquatic toxicology at the University of Southern Denmark. “They need something hard to attach themselves to and often they find a suitable surface on the inside of the pipes carrying water from the Great Lakes into factories and other industries along the lake. Often they sit so close that they block the water intake.” (October 3, 2013) Red Orbit [more on Zebra Mussels in our area]
  • Using the Law to Battle Zebra Mussels and Other Unwanted Pests DENTON — Every two months, Christopher J. Churchill, a United States Geological Survey biologist, scuba dives in Ray Roberts Lake, northwest of Dallas, to monitor the growth rates of zebra mussels, which have wreaked havoc on several Texas lakes and rivers. “A year ago, it was hard to find just one zebra mussel,” Mr. Churchill said. “They’re everywhere now.” Mr. Churchill’s assignment follows the discovery in 2009 of the nonnative zebra mussels in Lake Texoma in North Texas. That year, the area lost 28 percent of its water supply when local officials halted pumping water from the lake for fear of spreading the mussels through a pipeline that pumped water to a second reservoir, which is connected to a water treatment facility.

  • Zebra mussels are transforming the Great Lakes and fueling rampant algae growth EMPIRE -- Ron Long recently visited one of his favorite beaches at Sleeping Bear Dunes National Lakeshore, only to find it marred by dark green algae that clouded the water and piled up on the sand. "This is the worst I’ve ever seen this beach -- and I’ve been coming here for 50 years. It’s really sad," said Long, a Milford resident who was visiting the popular Esch Road beach near Empire.  (August 28, 2012)  MLive [more on Zebra Mussels in our area]


  • Report says mussels, nutrients damage Great Lakes - WSJ.com TRAVERSE CITY, Mich. — A one-two punch of excessive nutrients and ravenous mussels is causing a sharp drop-off in Great Lakes fish populations and the worst outbreak of algae blooms in decades, says a report released Tuesday. Runoff from farms, city parking lots and other sources is causing a flood of nutrients such as phosphorus in near-shore areas and bays, the National Wildlife Federation said in a report based on government and university studies. Meanwhile, deeper waters are experiencing the opposite problem: Invasive quagga and zebra mussels are gobbling too much food, causing fish higher up the chain to go hungry.  (October 6, 2011) Business News & Financial News - The Wall Street Journal - Wsj.com  [more on Zebra Mussels in our area]
  • Gut wrencher: Researchers seek magic bullet to control mussels Scientists have identified a new weapon to ward off two troublesome Great Lakes invaders: A bacterium strain that destroys their guts. It may prove to be an environmentally friendly and effective method of controlling quagga and zebra mussels. Introduced to the lakes in the 1980s, the mussels eat up things like phytoplankton – food that native fish and other life depend upon.
