Groups float ideas for stopping Asian carp migration

A privately funded group continues work on a fast-track plan to stop invasive Asian carp from reaching the Great Lakes. The group hopes to release its plan in January. The Detroit Free Press reports one of the options includes a series of barriers in the Illinois River to stop the destructive species from traveling from the Mississippi River through Chicago to Lake Michigan. Minnesota is part of a suit to force federal officials to speed up the effort to halt the fish before they spread further.

Asian carp may infiltrate Minnesota from northwestern Iowa

State officials on the lookout for Asian carp have been monitoring the Mississippi River. But there are new fears that the invasive species may use another gateway to Minnesota. Anglers in northwestern Iowa have caught dozens of the carp in waters that connect through streams and lakes to southern Minnesota.

Feds agree to shorter timeline for developing Asian carp strategy

The U.S. Army Corps of Engineers says it will come up with a short list of options for blocking the spread of the invasive fish by the end of next year. The Corps had earlier said the process would take until 2015. Asian carp have already invaded the Mississippi River watershed. Officials hope to keep them from migrating into the Great Lakes.

DNR pushing for $7M to build Asian carp barrier

The DNR says there's evidence that the carp, which can grow to 60 pounds and outmuscle native species for food, are in the St. Croix River. However, Wisconsin DNR officials say the barriers aren't 100 percent effective and it may be a worthless effort at this point.
