Havana, IL, May 01, 2009 — The St. Lawrence River is one of the best places in the world to fish for carp. But few anglers would think to eat them. Out in the Midwest, there are rivers flush with a species of carp that shouldn't be there in the first place. The Asian Carp is one of the Great Lakes most aggressive and damaging invasive species, pushing out native fish. There are entrepreneurs who dream of getting rid of Asian carp by turning them into food. Shawn Allee looks at what they've cooked up and whether it could do any good.  Go to full article

Sep 12, 2007 — This month, biologists in New York and Vermont are spreading a chemical in a half-dozen rivers and deltas near the shore of Lake Champlain. The chemical is designed to kill an invasive organism called sea lamprey. The parasites have decimated native trout and freshwater salmon in the lake. But the lamprey battle is only one front in a growing region-wide war against invasive species. Dozens of alien organisms have arrived in the North Country, some carried in the ballast tanks of freighters on the St. Lawrence Seaway, others introduced as garden plants or bait fish. As Brian Mann reports, researchers say these invasive organisms could have a cumulative impact on lakes, rivers and forests that is far more rapid and perhaps more profound than global climate change.  Go to full article
