In November of 2010, researchers from the University of Notre Dame collected water samples from several Milwaukee waterways including the Milwaukee, Menomonee, and Kinnickinnic rivers among others. These water samples were then analyzed to see if they contained Asian carp DNA. The good news is that they do not.
While DNA was found in southern parts of Lake Michigan earlier last year near the Illinois-Indiana border, it seems that the measures taken to block the carp from progressing northward have been successful, at least in keeping the invaders out of Milwaukee's waters. According to a brief article in the Milwaukee Journal Sentinel, "only one actual fish has been found above the barrier." Current focuses are on making sure that the carp are blocked from making it further north up the Mississippi River.
More information about this research can be found in this DNR news release. View our previous blog posts on Asian carp here. There are also several books dealing with Asian carp in our invasive species recommended reading list.
