Coastlines January/Febuary 1999 - Connecticut Becomes the 19th State Invaded By Zebra Mussels.
Zebra mussels, thumbnail-sized freshwater mollusks that arrived in the United States through ship ballast water in 1986, have invaded their 19th state with the confirmation of their presence in East Twin Lake in Salisbury, Connecticut, according to an announcement from the Connecticut Sea Grant College Program.
Slide #32 (zebra mussels) in a slide show. This site discusses threats to the Great Lakes ecosystem that continue to plague us and that will be hard to solve. For example, exotic species have had a huge impact on the Great Lakes ecosystem and remain a serious challenge.

Aquatic Invaders.
This 30 minute TV special takes a look at the threats these aquatic nuisance species pose, and how scientists, the public, and policy makers are working to prevent the spread of these potentially devastating invaders. May be viewed using Windows MediaPlayer.

River Invaders: The Scourge of Zebra Mussels.
Small, remarkable creatures... far more sophisticated than one can imagine, and perhaps the most threatening of all exotic species that have invaded North American waters. Their numbers are phenomenal... their spread is rapid... and in their wake is a trail of death and destruction.
Coastlines October 1999.
Washington is the fourth state in the nation to adopt a plan to minimize the introduction of nonnative aquatic nuisance species and eradicate alien species already present. These alien species can severely disrupt the habitat of important native species.
Academy 2000 - Invasive Nonnative Species.
It is increasingly important that watershed managers become aware of invasive exotic species in their watersheds, in both the aquatic and terrestrial environments. Several Web sites with exotic species information can be useful.
State of the Lakes Ecosystem Conference '96: Nearshore Waters Status and Trends.
The nearshore areas of the Great Lakes are diverse physical habitats, exhibiting a range of morphometric features, current velocities, substrates, and aquatic vegetation.

Nonindigenous Species. Prevent introductions and control existing populations of nonindigenous species in U.S. ocean and coastal waters. One of the primary sources of aquatic nonindigenous species is discharge of ballast water in ships.
At least 2.4 million gallons of ballast water arrive in U.S. harbors from foreign ports every hour, according to a recent Sea Grant 1 study. The average ship coming into San Francisco Bay to tank up on oil or load bulk cargo may unload 3 to 13 million gallons of ballast water.
Coastlines October 1999.
Such ominous visions are becoming increasingly common as exotic species continue to be introduced into this nation's waters from ocean-going vessels that sail from ports all over the world.
1998 Great Lakes Guidance Preproposal Selection.
In November, 1997, GLNPO solicited preproposals for $4 million in projects to be funded during 1998. The requested funding categories were: habitat protection and restoration; contaminated sediments; pollution prevention; exotic species; and emerging issues.
Issues - Introduced Species.
Introductions of nonnative species may be intentional or unintentional. In addition to the accidental introduction of nonnative species, introductions may occur from species deliberately brought into the country. History of introduced species in North America.
Great Lakes Report to Congress: Chapter 5 - Feb 94.
This chapter presents FYs 1989, 1990, and 1991 accomplishments pertaining to the Great Lakes, as reported by five Federal agencies.
EPA Region 1 - Press Release.
In recognition of the increasing importance of the Internet as a global communications tool, the U.S. Environmental Protection Agency's New England office today released the 1997 State of the New England Environment Report.
Habitat Assessment Management Measure.
Site and design marinas to protect against adverse effects on shellfish resources, wetlands, submerged aquatic vegetation, or other important riparian and aquatic habitat areas as designated by local, state, or federal governments.
Great Lakes Project Summaries 1998.
In FY 99 GLNPO looked for projects in the areas of Contaminated Sediments, Pollution Prevention and Reduction (pursuant to the Binational Toxics Strategy), Habitat (Ecological) Protection and Restoration, Exotic Species, and Emerging Issues.
This Sea Grant Nonindigenous Species Site (SGNIS) is a project of the National Sea Grant College Program, produced by the Great Lakes Sea Grant Network. It is a national information center that contains a comprehensive collection of research publications and education materials produced by Sea Grant programs and other research institutions across the country on zebra mussels and other aquatic nuisance species. All materials available through this home page have either appeared in professional science journals or have been through a rigorous scientific review to ensure the quality of the information provided.
Number of articles = 713.
Mollusks (Phylum Mollusca) are found in marine, brackish, and fresh waters. Common methods of introduction include ballast water introductions, aquarium releases, and accidental release from aquaculture facilities. Displacement by competition is the most frequently observed impact on native species. The most notable nonindigenous mussel introduction is the zebra mussel (Dreissena polymorpha), a native of eastern Europe. Since its initial introduction, the zebra mussel has proven to be a very costly pest to municipal and industrial water users. Additionally, zebra mussels can destroy entire colonies of native mussels by interfering with such basic functions as respiration, reproduction, feeding, growth, and movement.
Looking for slides, prints, or illustrations of Great Lakes nonindigenous aquatic nuisance species? Look no further. Michigan Sea Grant has compiled the Great Lakes Sea Grant Network Exotic Species Graphics Library, containing approximately 100 images. Color slides, illustrations, and black-and-white prints are distributed on a three-week loan basis; or copies may be purchased for a nominal fee.
This library contains slides of the following exotics: zebra mussel, goby, spiny water flea, sea lamprey, ruffe, and purple loosestrife. These slides may be accessed at this site or a copy may be ordered from Michigan Sea Grant using the order form at the end of the document.
Sea Grant's National Aquatic Nuisance Species Clearinghouse is home to North America's extensive technical library of publications related to the spread, biology, impacts, and control of the zebra mussel (Dreissena polymorpha and Dreissena bugensis).
Frequently asked questions about the zebra mussel. The author and his daughter, a student at Berkley High School, Michigan, did this interview together. The author's daughter recently wrote a school report on zebra mussels.
Basic source for zebra mussel information. Dreissena polymorpha, known by its common name as the zebra mussel, originated in the Balkans, Poland, and the former Soviet Union. These mollusks get their name from the striped pattern of their shells, although patterns can vary widely.

Zebra Mussel Research Program.
The Zebra Mussel Research Program (ZMRP) was authorized by the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990, Public Law 101-646, and is the only federally authorized research program for the development of technology to control zebra mussels.
Basic information on the Zebra Mussel (Dreissena polymorpha).
Zebra Mussel Abstract. Zebra Mussel and Aquatic Nuisance Species.
Reviews the nature, transport, control, and regulation of numerous nonindigenous nuisance species, describes their ecology, effects, and environmental impacts in various freshwater habitats, conveys research results and some economic evaluation of methods to control the spread of these nuisance species, especially in cooling and service water systems, and addresses technology transfer, education, and outreach as well as sociological and related issues. Methods, concepts, and background information are also provided to prevent the future introduction of nuisance species into aquatic ecosystems as well as limit their spread and economic impact.

This program is tuning kids into zebra mussels and other exotic species.
Drifting Macrophytes as a Mechanism for Zebra Mussel (Dreissena polymorpha) Invasion of Lake-outlet Streams.
In an effort to find out if aquatic plants play a role in the dispersal of this pest, the scientists collected macrophytes in an outflow creek of an invaded lake in Michigan. Their results showed that, on average each day, 2,620 adult mussels left the lake, hitchhiking on drifting aquatic plants.
The main objectives of this Mini-teach are to show the proliferation of zebra mussels and their effects on local bodies of water.
