Zebra Mussels - Rochester, NY area
Consider how profoundly the invasive species Zebra Mussels have affected our area.
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.
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.
- 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.

- 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.

- Zebra Mussels (and Lots of Other Species) Invading Great Lakes and No One Can Decide What to Do About It : TreeHugger Out of the 185 invasive species in and around the Great Lakes, zebra mussels are posing a painful problem. The mussels have sharp shells and a tendency to slice up the feet of beach-goers. The mussels have hitched rides in the ballasts of ships coming into port, and while politicians have tried to get the shipping industry to help curb the problem through regulations, there haven't been any successes. Well, unless you're looking at it from the perspective of zebra mussels. But with 15,000 lakes to worry about, standing around bickering about what to do isn't helping the situation.

- Zebra Mussel's impact anything but clear - After becoming so badly polluted it was labelled a “dead lake” in the 1960s, few would have imagined the waters of Lake Erie would one day be compared to the vibrant hues of the Caribbean. But in an ironic twist of fate, a destructive invasive species that entered the Great Lakes about 20 years ago has created increasingly clear waters, leaving many to reasonably assume the lakes keep getting cleaner and healthier. But it's just an illusion created by the zebra mussel — a tiny interloper that's killing off life under the surface even as it continues to make all the Great Lakes look more and more picturesque.

Key Online Resources for Zebra Mussels
- Dreissena polymorpha (Pallas, 1771) - Encyclopedia of Life "Zebra mussels were originally found in the drainage basins of the Black and Caspian Seas, including the Danube, Dniester, Volga, and Ural Rivers. Shipping and canal construction in the 19th century allowed them to spread west into most European rivers and lakes. In the late 20th century they were accidentally brought to North America, probably in ballast water of large ships. They now occur in the Great Lakes basin, most of the Mississippi River drainage, the Hudson River and many other eastern North American rivers.

- Zebra Mussels A small freshwater mollusk called the zebra mussel (Dreissena polymorpha), has been steadily invading America's rivers and lakes. Zebra mussels originated in the Balkans, Poland, and the former Soviet Union. They first appeared in North America in 1988 in Lake St. Clair, a small water body connecting Lake Huron and Lake Erie. Biologists believe the zebra mussels were picked up in a freshwater European port in the ballast water of a ship and were later discharged into the Canadian side of Lake St. Clair. --from National Atlas home page
