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:

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:
