Another skirmish is erupting in the ongoing battle between Ontario and
Minnesota over sport fishing. Ontario recently banned the importation
of leeches without a permit. The reason – the Province says it doesn’t
want to risk exotic species piggy-backing on the popular bait. But as
the Great Lakes Radio Consortium’s Stephanie Hemphill reports, experts
on controlling exotic species say the reasoning is faulty:

Sea Lamprey Soufflé?
A recent discovery has put the brakes on a plan to market Great Lakes sea lamprey to Europeans as a gourmet food. Scientists have found high levels of mercury in the lamprey, making it unfit to eat. The Great Lakes Radio Consortium’s Mike Simonson has the story:
New Invasive Species Found
A new exotic species is invading the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham reports that this new invader has been causing problems for anglers:
Zebra Mussels Remain Threat to Great Lakes
Zebra mussels, those pesky thumb-nail size creatures that began invading the Great Lakes about a decade ago, may be a bigger threat than we first thought. The Great Lakes Radio Consortium’s Bill Cohen reports:
Id Cards Track Exotic Fish
As the Great Lakes fishing season gets into full swing, an"exotic" ID card is being distributed to sport anglers all over theRegion. Its part of an research effort to track the spread of twoexotic species—the Round Goby and the Eurasian Ruffe (rough). The GreatLakes Radio Consortium’s David Hammond reports:
Policing Ballast Water
Controlling exotic species in the Great Lakes hasn’t been easy. Scientists have been unable to slow the spread of things like the zebra mussel. But they still have a chance to prevent other non-native species from infesting Great Lake waters. The Great Lakes Radio Consortium’s Steve Frenkel reports on a potential breakthrough:
Restoration Practices Generating Controversy
Years ago, forest preserves were established in many American cities toprotect valuable natural areas from urban development. But over theyears, the health of those preserves has declined. Conservationists arenow trying to repair the damage by actively restoring those naturalareas. But now, some of their techniques are being questioned. TheGreat Lakes Radio Consortium’s Steve Frenkel reports:
Lamprey Eel Control
A new strategy to fight the lamprey eel should mean higher fish populations in Lake Michigan and Lake Huron. The Great Lakes Radio Consortium’s Mike Simonson reports on this break-through:
Commercial Lamprey Harvest May Soon End
A program to control the invasion of exotic species has got the lamprey eel under control throughout the Great Lakes…everywhere except the St. Mary’s River. But now, the lamprey are the target of a new time-release chemical that should reduce the lamprey population by 85-percent. But as the Great Lakes Radio Consortium’s Mike Simonson reports, bringing the species under control will mean the end to a recent money-making experiment:
