Plans for an underwater electric fence to prevent Asian carp from entering the Great Lakes system may be in jeopardy after commercial shippers raised concerns about the safety of their ships. As reported by The Chicago Tribune, there was an incident in 2002 where crew members spotted an electrical arc when their barges entered the Chicago Ship and Sanitary Canal. (Um, 2002? Why is this coming up a month before the new barrier is set to be turned on?)
