"The U.S. Supreme Court on Monday rejected an appeal by five states seeking an order requiring that a range of steps be taken to keep the invading Asian carp out of the Great Lakes where they are considered a threat to fisheries."
"The high court refused to hear an appeal by Michigan, Minnesota, Ohio, Pennsylvania and Wisconsin after the states lost their bid for a preliminary injunction that would have required additional efforts to stop the migration of the voracious carp into the lakes.
The carp have taken over stretches of the Mississippi River and its tributaries. The U.S. Army Corps of Engineers and the Chicago area waterway system already have adopted a number of measures to block the advance of the carp into Lake Michigan."
