CHICAGO (AP) — Federal and Illinois officials are releasing plans to monitor and control Asian carp in Illinois waterways this year.

Biologists will continue intensive sampling of waterways that connect the lake with the Mississippi River watershed to determine if any carp have breached those barriers, but will cut back on DNA sampling. Such sampling will be conducted twice above the barriers.
