The Associated Press has a preview of an extensive federal plan that would keep Asian carp from encroaching on the valuable fish populations of the Great Lakes. The $50 million plan is expected to be officially released later Wednesday.
The plan includes a combination of high tech detection systems and public works projects across the inland seas that would create barriers to the invasive species, even as they continue infesting the Mississippi River and many tributaries.
Decades ago, the carp were imported to clear algae from fish farms and sewage lagoons in the south but escaped during floods and migrated north.
An electric fish barrier in the Chicago Ship Canal is keeping the voracious carp at bay. Under the plan, a new section would be added. The plan also calls for additional projects to block carp on rivers flowing into the Great Lakes. Additionally, federal agencies will develop and test new methods of catching, killing and controlling the unwanted fish. Teams also will expand water sampling.
With this year's spending, the administration will have devoted $200 million over four years to keep the Great Lakes carp-free.
