Asian carp could find a good home in Lake Erie

Rebecca Williams Michigan Radio

Asian carp have been making their way up the Mississippi and Illinois Rivers toward the Great Lakes for decades. Bighead and silver carp are the species people are the most concerned about.

There’s been a lot of focus on keeping carp out of Lake Michigan.

But a new study finds carp might do well in Lake Erie and some of the rivers that feed the lake.

Patrick Kocovsky is a research fishery biologist with the U.S. Geological Survey. He says it’s believed Asian carp need specific conditions to make babies.

“What’s currently believed is Asian carp require some kind of flood event in a tributary.”

He says the carp need just the right temperature... a river that’s flowing fast enough and a stretch of river long enough to reproduce.

Kocovsky and his team studied the major tributaries of Lake Erie. They found that the Maumee River is highly suitable for Asian carp to lay eggs.

The researchers found the Sandusky and Grand Rivers to be moderately suitable for carp.

Patrick Kocovsky says if carp can get into Lake Erie, the western side of the lake is likely to be the most hospitable.

Army Corps to turn up juice on carp barrier

Asian carp have been making their way up the Mississippi and Illinois Rivers toward the Great Lakes for decades. Bighead and silver carp are the species people are the most concerned about.

Government officials are trying to keep the carp out of Lake Michigan. One of the main methods they’re using is electrical shock. There’s a man-made canal near Chicago that connects the Mississippi River system with Lake Michigan. And on that canal is a system of three underwater electric barriers built by the Army Corps of Engineers.

I recently had a chance to visit the electric barriers. You can’t see the actual barriers, because the electrodes are underwater. But the Army Corps invited me into the control room of Barrier 2B. It looks about like you’d guess – lots of computers and gauges. There are a couple large mounted Asian carp on the shelves.

Chuck Shea is a project manager with the Army Corps.

He says the barriers repel fish by emitting very rapid electric pulses into the water... which, if you’re a fish, is not a whole lot of fun.

“The idea is, as a fish swims in, the further it goes it’s getting a bigger and bigger shock and it realizes going forward is bad, it’s uncomfortable, and it turns around and goes out of its own free will and heads back downstream.”

The electric bill for this barrier runs between $40,000 and $60,000 a month.

Crews looking for Asian carp in Lake Calumet

Crews in Chicago are on the hunt for Asian carp this week. The term Asian carp refers to two species: bighead and silver carp. The crews are looking for the carp in Lake Calumet, which is linked by a river to Lake Michigan. Asian carp have been found in the rivers that feed into Lake Michigan from Illinois.

John Rogner is the assistant director of the Illinois Department of Natural Resources. He says they’re looking for live carp after finding carp DNA in Lake Calumet.

He says it could mean there are live Asian carp in the lake.

“But there are some other possibilities. One is that there is DNA that comes upstream from downriver from boat hulls; it might be coming from restaurants in parts of Chicago that come out through the storm sewers.”

Some restaurants in the city serve Asian carp, so waste water could contain DNA from the fish. Rogner says people could also be releasing live carp into the lake, even though that’s illegal.

He says so far this week, they have not found any live bighead or silver carp in Lake Calumet.

Carp czar says faster action plan 'unrealistic'

The Obama Administration’s point man on the Asian Carp crisis says there’s no way to speed up the efforts to permanently keep the invasive fish from reaching the Great Lakes.

The Asian Carp have destroyed native fish populations in the Mississippi River and have swum within a few miles of Lake Michigan.  There are concerns that if Asian Carp enter the Great Lakes ecosystem, they will overwhelm and destroy the region's multi-billion dollar fishing industry.

Several members of Congress want the U.S. Army Corps of Engineers to speed up their 5 year review of possible action plans to stop the carp. Michigan Senator Debbie Stabenow says time is important.

 “We have to have a sense of urgency about it.  The Army Corps is studying this issue now, but it’s going to take them several years…we don’t have several years.  We need to get this done as quickly as possible.”   

But Obama Administration Carp Czar John Goss says the 18 month schedule proposed by members of Congress is not enough time. 

 “Realistically I think it’s going to take substantially longer than that to get the right solution in the long term.”

Major General John Peabody is the commander of the Corps of Engineers ‘Great Lakes & Ohio River’ Division. He says finding a solution will take more than 18 months. 

“I never say never, because you don’t know what you don’t know about the future.   But in our judgment it’s not possible because of the complexity of the situation.”

The president’s top people on the Asian Carp crisis held a public hearing today in Ypsilanti.

US House rejects Michigan lawmaker's request to hold up money for Chicago canal

Michigan congressman Dave Camp had hoped he could cut off federal funding to reopen the Chicago Sanitary Canal.  The canal could be the main path of Asian Carp may take from the Mississippi River watershed to Lake Michigan.   The Associated Press reports last night's vote wasn't close:

John Goss, the Obama administration's so-called 'Asian carp czar,' was in Traverse City yesterday to talk about how the federal government is trying to keep Asian carp out of the Great Lakes. Goss said the government is moving as fast as possible to keep the species out of the Lakes. There's concern that if the carp made their way into the Great Lakes it would devastate the waters' ecosystem.

Want to hear how the federal government plans to keep Asian carp out of the Great Lakes? Well, now's the time. John Goss, the Obama administration's point man in the fight against Asian carp, will be part of a federal delegation visiting Traverse City today for back-to-back public meetings.

The Associated Press reports:

The officials will outline their strategy and take comments on a long-range study of how to prevent the carp and other invasive species from migrating between the Great Lakes and Mississippi River basins.

Environmentalists, Michigan and four other Great Lakes states want to sever the man-made link between the two aquatic systems. The Army Corps of Engineers is conducting the study and says that's one option.

Activists also say the study's planned completion date of 2015 isn't soon enough.

There's concern that if the Asian carp make their way into the Great Lakes that they could wreak havoc on the lakes' eco-systems.

New law bans importation of bighead carp into U.S.

There's a new federal law that bans bringing bighead carp into the U.S. The bighead carp is among the Asian carp species that threatens the ecosystem of the Great Lakes.

President Obama signed the bill known as  The Asian Carp Prevention and Control Act yesterday. The Associated Press reports that the measure:

...adds bighead carp to a list of wildlife that cannot be imported or taken across state lines. The only exceptions would be for scientific, medical or educational purposes and would require a permit. Bighead and silver carp have infested waterways in the Chicago area. Authorities are trying to prevent them from getting into the Great Lakes, where they would compete with native fish for food.

The bill was written by Michigan Democratic Senator Carl Levin and sponsored by Michigan's other Democratic Senator Debbie Stabenow.

Michigan loses legal round in Asian Carp battle

The state of Michigan has suffered another legal setback in its effort to keep Asian Carp from reaching the Great Lakes.  

A federal judge in Chicago has denied a request by Michigan and several other states to order the closure of canals which link Lake Michigan to the Mississippi River basin. Asian Carp are a voracious invasive species.  The carp have devastated Mississippi River fish populations.  

“The court agreed that Asian Carp are indeed a threat," says Joy Yearout,  a spokeswoman for Michigan Attorney General Mike Cox, '"But the judge also ruled the actions the federal government has taken over the last several months prove they are addressing the threat enough to make it not immediate enough to require a court order."

Federal agencies have stepped up construction of electric barriers to keep Asian Carp from passing into Lake Michigan.  Other methods are also being studied. 

The states may continue their legal fight.  They are also asking President Obama to order the canals closed.

Throwing money at the Asian Carp problem

The Associated Press reports that The Charles Stewart Mott Foundation is giving $500,000 to the Great Lakes Commission to help it find ways to stop the invasive Asian carp from entering the Great Lakes.

The fish started make their way up the Mississippi River system more than ten years ago after they escaped from fish farm ponds in the south. They were imported to control parasites in the ponds.
