Courtesy kate.gardiner The commercial fishing industry in the Great Lakes, worth more than $7 billion a year, is threatened by Asian carp. Asian bighead (Hypophthalmichthys nobilis) and silver (H. molitrix) carp imported in 1970 to remove algae from catfish farms escaped into the Mississippi River during a flood. Since then they have outcompeted other fish. Along some stretches of the Illinois River, the carp make up 95 percent of the biomass. In December, the State of Michigan filed a lawsuit against the State of Illinois to close of locks between Chicago-area waterways and Lake Michigan.
"We cannot allow carp into the Great Lakes. It will destroy our Great Lakes fisheries, the economy," Michigan Gov. Jennifer Granholm said in a prepared statement." New York Times
On Jan 19, 2010, the U.S. Supreme Court turned down Michigan's request to block Asian carp invasion of Great Lakes (Scientific American). The Supreme Court didn't reveal any of the reasoning behind its ruling, which simply read: "The motion for preliminary injunction is denied."
Governor of Michigan, Jennifer Granholm, is "asking for an immediate summit at the White House with the administration to shut down these locks, at least temporarily, until a permanent solution can be found.”
The AP reported the White House response to be:
“The Obama administration clearly understands the urgency of this critical issue, and we look forward to meeting with them on the threat the Asian carp poses to the Great Lakes.” Dayton Daily News
