Zebra mussel-killing bacteria could help native species in the Great Lakes

You can hear Peter's story above.

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.

It could be good news, though, if you’re a clam.

Michigan agencies step up invasive species fight

LANSING, Mich. (AP) - Michigan officials say after years of planning, they're ready to put in place a strategy for controlling the spread of invasive species in the state's waterways.

The plan is described in the annual "State of the Great Lakes" report released Thursday by the Department of Environmental Quality.

Aquatic invaders such as quagga mussels cost the region hundreds of millions of dollars a year.

The newly developed strategy focuses on early detection of new invaders and a rapid response to rein them in.

New York State backs away from stricter ballast water regulations

The Associated Press Reports: New York State will not be imposing stricter regulations on ships potentially carrying invasive species into the Great Lakes.

In the past, ships carrying ballast water for stability have brought invasive species including quagga mussels, spiny water fleas and round gobys to the Great Lakes from Europe.

New York State controls access to the St. Lawrence Waterway, which is the gateway to the Great Lakes.

Michigan ecologists want new strategies to manage zebra mussels in Great Lakes

Ecologists from the University of Michigan say invasive zebra and quagga mussels are causing dramatic changes to the ecosystems in northern Lake Michigan and Lake Huron. Their report says action must come soon to stop the spread of the mussels in the Great Lakes.

Donald Scavia  is the Director of the University of Michigan Graham Environmental Sustainability Institute. He's one of the authors of a new report that says the changes are happening quickly and require more attention than they are getting now:

“Our management strategies need to be able to be reviewed and modified every couple of years rather than every couple of decades.”

Scavia said the zebra mussels make it difficult to predict the conditions of the Great Lakes from year to year.
