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.

Videoconferencing Project: Zebra Mussels: Lessons Learned in the Great Lakes.
An Overview of Biology, Impacts, Prevention and Control of a Freshwater Invader. Four videotapes available on 1) zebra mussel biology and relationships to the ecosystem (10 min.); 2) spread and impact on inland surface waters (10 min.); 3) prevention and control practices (10 min.); 4) Lessons Learned in the Great Lakes: technical and educational resources available (15 min.).
Four videos available to view using RealPlayer on: Outreach tools, Control, Biology, and Spread and Impact.
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.

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 US 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.

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.
The Zebra Mussel and Aquatic Nuisance Species Office updates and publishes a map of zebra mussel sightings in Michigan waters and a database of lakes monitored each year.
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).
Zebra mussels in Vermont. Vermont Department of Environmental Conservation.
Previous studies on the zebra mussel (Dreissena polymorpha) have examined tolerance limits of dissolved oxygen and temperatures that can be used in controlling this exotic pest. This study wanted to determine if colonization of the zebra mussel in the Atchafalaya Basin would be deterred by the natural seasonal phenomenon of increased temperatures and decreased oxygen saturation.
