Judas test: Will carp betray their own? on the Great Lakes Echo says that University of Minnesota researchers are working to put a new tool in the arsenal of those seeking to thwart the voracious and invasive Asian carp.

Watch the report from CBS Minnesota to learn how researchers hope to use the same technique to locate Asian carp populations for extermination.
