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.

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.
