Revealing the relationship between the natural world and the everyday lives of people
Category: Asian Carp Invasion
The Environment Report has been covering the introduction of the Asian Carp species since January of 2000, when catfish farms in the south were importing them to control pests. The fish have since spread throughout the Mississippi River system. Millions of dollars of taxpayer money has been spent to try to keep these foreign species from swimming into the Great Lakes. Some scientists say their presence in the Great Lakes would be an “ecological disaster.” Today, evidence of an Asian Carp species was found above an electric barrier designed to prevent their movement into the Great Lakes.

By summer’s end, officials from the Army Corps of Engineers and the
state of Illinois hope to finish an underwater electric barrier in a canal just south
of Chicago. The barrier is designed to repel invasive fish such as the Asian Carp.

By summers end, officials from the Army Corps of Engineers and the state of Illinois hope to finish an underwater electric barrier in a canal just south of Chicago. The barrier is designed to repel invasive fish such as the Asian Carp. But some environmentalists fear the barrier won’t be enough to keep the voracious, non-native species out of Lake Michigan. The Great Lakes Radio Consortium’s Shawn Allee reports:
Some conservationists worry Asian Carp may someday enter the Great Lakes by simply hitching a ride.
These critics say leaky ships passing through the electric barrier could hold carp eggs inside their ballast tanks and deposit them on the other side. But local officials say that scenario is unlikely.
Steve Stuewe is with the Illinois Department of Natural Resources.
He says Asian Carp eggs need turbulent water, and if they do find their way into rusty ballast tanks…
“They will probably be dead because they’ve settled out into the bottom of the hull and they’ve either suffocated or they’re down there, mixed in with the iron oxidate. So, they sink. They have to float.”
The research on egg viability is still sketchy, but a federal study of the issue may settle the question once and for all early this summer.

Two federal agencies say they’ve worked out safety problems that might’ve caused delays at a new electric barrier designed to keep Asian carp out of the Great Lakes. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:
There’s already one underwater barrier at a canal south of Chicago and a second set of electrical cables is being installed. The shipping industry has been worried about the barriers causing safety problems like electrical arcing between vessels. The Army Corps of Engineers and Coast Guard have been working with the private firms and have come up with recommendations to reduce the risk of danger. The suggestions include no mooring, passing, or stopping near the barriers and using wire rope to prevent barges from separating. Coast Guard commander David Fish says the plan should work.
“We think we have something. You get enough people… working on a project… get enough people all wanting the same solution and engineering-wise, we’re able to find a solution.”
But Fish says there are no firm guarantees the second carp barrier will be ready this spring, before the first barrier wears out.

The U.S. Army Corps of Engineers is building a nine million dollar electric barrier to keep Asian carp out of the Great Lakes. But now the Corps is warning the fence in Romeoville, Illinois, might not be enough. The Great Lakes Radio Consortium’s Lynette Kalsnes reports:
The Army Corps is building the electric barrier in the Chicago Sanitary & Ship Canal. But the Des Plaines River runs near the canal, and it often floods in the spring. Chuck Shea is the project manager for the Army Corps of Engineers. He says they might need to build a flood wall or levee so high waters can’t sweep fish past the new barrier.
“It’s possible that water from the Des Plaines River could run into the Chicago Sanitary and Ship Canal. And if it was a large enough flood and there were fish in the right place, they might be able to use that as a pathway to enter the Chicago Sanitary and Ship Canal.”
Shea says while this possibility is unlikely, it still will be an important issue to study down the road. He says the more pressing concern is that an existing temporary barrier could wear out before construction on the permanent barrier is finished.
Asian carp have been spotted about twenty miles downstream from the electric fence. The giant fish are considered a threat to sport and commercial fishing. Shea says state officials are working to find money for the last phase of the electric barrier project.

A new barrier is being constructed to prevent the Asian carp

will seek money to keep an existing barrier in operation, as well. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:
The permanent underwater electronic barrier that’s being built in a canal near
Chicago is close to a temporary barrier that’s wearing out. But Illinois Republican
Judy Biggert
contends the new electronic fence will not be enough to keep out the voracious
invasive species
known as the Asian carp.
“Now I wish that I could say that with the construction of this permanent barrier
that our work
would be finished and the carp would never again threaten the Great Lakes, but I
cannot.”
Biggert wants to make the temporary barrier permanent, too. She also wants to make
sure there’s
federal money to operate and maintain both underwater fences over the long term.
So, Biggert is
seeking co-sponsors for a barrier bill that she says she plans to introduce early
this session of
Congress.
Her aides say she may also try to get the several million dollars needed for the
project put in the
budget for the Army Corps of Engineers. But many new domestic spending proposals
could face
a tough time in Congress, if conservatives try to reduce the federal budget deficit.

The U.S. House and Senate recently passed a bill that will help keep Asian carp out of the Great Lakes. As the Great Lakes Radio Consortium Celeste Headlee reports, the federal government will contribute nearly two and a half million dollars to help repel the fish:
Asian carp are huge, often growing to be four feet long and weighing 80 pounds. They are also extremely prolific and voracious. Most Asian carp consume up to 40 percent of their body weight every day. There is currently an electric fish barrier strung across the bottom of the Chicago Sanitary and Ship Canal to keep the fish out of the Great Lakes. The barrier creates an underwater field of electricity that repels the carp.
Andy Buchsbaum is the director of the National Wildlife Federation’s Great Lakes Office. He says the current barrier is temporary and due to fail next year.
“Today the Great Lakes really dodged a bullet. Right now, the carp are poised 20 miles away from the failing barrier, which is just downstream from Lake Michigan. And if that barrier fails, then essentially the Great Lakes as we know them are over.”
The U.S. House and Senate passed a bill that will supply 75 percent of the funds for building a new barrier. The Great Lakes governors have agreed to supply the rest of the money. President Bush has said he will sign the bill when it reaches his desk. Buchsbaum says the new barrier can be completed within 60 to 90 days.

Officials from a joint U.S./Canada Commission that monitors the health
of the Great Lakes is asking states and provinces in the region for
help. The International Joint Commission wants the governments to chip
in money to make sure that Asian carp don’t invade the Great Lakes and
decimate the fishing industry. The Great Lakes Radio Consortium’s Bill
Cohen reports:
A temporary experimental electronic barrier in the Chicago Ship and
Sanitary Canal is the only thing keeping Asian Carp from swimming into
Lake Michigan. That’s why the federal government and Illinois have
allocated 6.7 million dollars to build a new permanent fence.
But now, the builders say they need an extra 1.8 million dollars to complete
the work. That’s why the International Joint Commission is asking all the
states and provinces that have a stake in the dilemma to come up with
that cash. John Nevin is a policy advisor for the IJC. He says if the
older barrier fails or the new one doesn’t work right, the carp will
wreak havoc with the Great Lakes:
“What they do is they swim along with mouths wide open and they filter
feed. They eat all the plankton and all the little stuff that little fish eat,
so they would potentially rob all the other fish in the lake of their food.”
Ohio’s Governor Bob Taft heads the Council of Great Lakes Governors.
He’s seeking input from other governors so he can issue a response soon
to the plea for money.

The war against terrorism nearly led to a biological invasion of the Great Lakes. The Army
Corps of Engineers was struggling to find money for a barrier to stop Asian carp from getting into
the Great Lakes. It wasn’t until a strong letter from 24 members of Congress was sent to the
Corps that the money was found. The Great Lakes Radio Consortium’s Lester Graham reports:
Asian carp have already invaded the Mississippi River system and they’re making their way
toward the channel that connects the Mississippi basin to the Great Lakes basin. The big fish is a
poster child for alien invasive species. It leaps out of the water, sometimes even hitting and
hurting boaters. It competes with native fish. And it’s feared that it would wreak havoc on the
Great Lakes fishery and the ecology of the lakes if it ever gets through to them.
South of Chicago, a barrier that electrifies the water is in place in the connecting channel between
the Mississippi system and the Great Lakes. It shocks the fish and seems to stop them from going
any farther. But that barrier is just a temporary demonstration project. So Great Lakes officials
were pleased when the Army Corps of Engineers announced it would build a permanent barrier.
Michael Donahue is President and CEO of the Great Lakes Commission. The organization
lobbies for the eight Great Lakes states.
“Most invasive species we find out about after the fact, once they’re in the system, they’re
established and the damage is being done. In this instance we know who the enemy is, where
they’re at, what pathway they plan to take to get into the lakes and what we need to do to stop
them.”
So environmentalists, anglers, conservationists and scientists all believe stopping the Asian carp
from getting into the Great Lakes is a pretty good idea.
Stuart Ludsin is a research scientist with the National Oceanic and Atmospheric Administration’s
Great Lakes Environmental Research Lab. Ludsin says we don’t know exactly how the Asian
carp will affect the Great Lakes… but we don’t want to find out either…
“We certainly do not want to let other exotic species into the system for fear of the economic and
ecological consequences that can come from an invasion.”
Sport fishing enthusiasts don’t need to know exactly what the Asian carp will do to the Great
Lakes. Jason Dinsmore is a resource policy specialist with the Michigan United Conservation
Clubs. Dinsmore says it’s pretty clear the Asian carp won’t be good for anglers.
“Our big concern is: these fish eat what our fish eat, I guess is the best way to look at it. These
large predatory fish are planktovores which means that they eat very small organisms that our fish
like, you know, juvenile perch will depend on. And if they’re out-competing the juveniles of our
sport fish, our sport fish will look to take a hit in overall numbers which means there’s going to
be less for our anglers to catch.”
So, there’s no problem, right? The Army Corps plans to build it. Everyone seems to think it’s a
good idea. But then the Corps couldn’t find the money for it. Chuck Shea is the project manager
for both the demonstration fish barrier and the new permanent fish barrier that’s being planned.
“Earlier in the month of February we didn’t have the full funding allocated to the project. The
project was not dead in any way. We were still working internally to try to find the money.”
The four-point-four million dollars to build the electric barrier to keep the Asian carp out of the
Great Lakes was to come from a 25-million dollar fund that the Corps uses for projects not
specifically authorized by Congress. It’s discretionary money. But this year money is tight and
with money being used for projects in Iraq and Afghanistan, it wasn’t clear the Great Lakes fish
barrier could get the money from the fund.
“The war on terror and homeland security issues are creating new demands on the budget, in
particular for the Army. The Army is heavily involved in supporting the war on terror and
homeland security and that does affect the budget overall, yes.”
That’s when 24 Members of Congress from the Great Lakes region stepped in. They signed off
on a letter calling for the immediate funding of the fish barrier project and started making calls to
the Army and anyone else who had influence on funding the project.
It looks as though the political lobbying might have worked. The Corps issued a news release
which indicates the corps expects to start construction of the second barrier this summer,
completing it this fall. In the meantime, the temporary barrier will keep running, hopefully
deterring the Asian carp from making it to the Great Lakes.
The Great Lakes Commission’s Michael Donahue says everyone hopes the barrier is completed
in time to stop the Asian carp because it’ll will cost a lot if it’s not.
“And instead of spending a few million dollars to prevent the invasion, we could be spending a
few hundred million dollars to deal with it once the Asian carp is established.”
The next challenge is finding money to rebuild the first electrical barrier and make the temporary
barrier permanent as well, backing up the new barrier in case it fails or needs to be shut down for
maintenance. No one wants to think about what might happen if the temporary barrier would
fail now before the permanent barrier is built. The Asian carp has been spotted as close as 20
miles from the barrier and only 50 miles from Lake Michigan.

Another major piece is about to fall into place in the battle to contain the Asian Carp from
spreading into the Great Lakes. Ontario’s ministry of natural resources is set to slap a ban on
importing the invasive carp. The Great Lakes Radio Consortium’s Dan Karpenchuk reports:
Toronto has a large appetite for the Asian carp. They’re imported to fish markets here live, so
they can be cooked fresh. But David Ramsay, Ontario’s minister of natural resources, says that’s
going to stop. He says he doesn’t know when the ban will go into effect. But it could be only
weeks that people will be able to enjoy their fresh carp.
The carp can grow up to eight feet in length, weigh more than one hundred pounds and consume
huge amounts of food….and they have no natural predators. Experts have warned that the Asian
carp could eat its way through the Great Lakes ecosystem.
Ramsay says the previous Ontario government did nothing about this invasive species, but he
says this government won’t wait.
“I’m very concerned about the invasive carp. We found one at the mouth of the Don River in
December. There’s a danger here, or a potential danger if these species of fish that are imported
into this country ever got loose in the Great Lakes, it could really put our Great Lakes ecosystem
in grave danger.”
This isn’t the first Asian carp to surface here. In the past two years one was found in Lake Erie,
and another in a fountain in downtown Toronto.

An invasive species known as Asian Carp is migrating toward the Great Lakes.

An invasive species known as Asian Carp is migrating toward the Great Lakes. Some scientists
fear the Asian carp will harm sport fishing in the lakes, if the carp ever get past some man-made
barriers. Anglers, state conservation officials, and others are trying to get the invasive fish on
Congress’s plate and even on yours. The Great Lakes Radio Consortium’s Chuck Quirmbach has
the story:
Asian carp escaped from southern U.S. fish farms a few years ago and the voracious eaters of key
parts of the food chain have been munching their way North on the Mississippi River and several
of its tributaries.
(sound of boat moving through water)
On the spoon river near Peoria, Illinois, the invasive carp are quite common. With a little
encouragement from a nearby electro-shocker, the large fish sometimes jumps out of the water
and right into a boat.
(sound of boat)
This two-foot long slippery visitor flips back and forth on the bottom of the aluminum boat until
Thad Cook of the Illinois Natural History Survey grabs the fish. Cook notes the markings of the
fish and says it’s one of the Asian carp known as a silver carp.
“It’s a healthy fish, cool to the touch, too.”
(sound of boat)
Not too far away, on the Illinois River, you can find more evidence of the Asian carp’s
prevalence.
Two other staffers of the Natural History Survey have caught about 40 Asian carp known as
bighead carp in a net that was only out for about twenty minutes. Erik harms holds open the
carp’s dark red gills.
“Those are the gills and they use that to filter out the phytoplankton, plankton.”
Researchers estimate there are now millions of Asian carp in the Illinois River. They’ve
continued to crowd out more of the native fish such as the white bass and buffalo fish. Not only
are the invasive fish causing problems for other fish… they’re causing problems for people. One
woman was injured this year when an Asian carp jumped and hit her in the head.
This big fish story might get worse. This year, the Asian carp migrated another 30 miles closer to
the Great Lakes. That puts the carp within 100 miles of Lake Michigan.
Phil Moy is with the Wisconsin Sea Grant. He says, look out if the carp gets in the Great Lakes.
“Well, it’s just gonna be another mouth to feed. We’ve seen some of the insult the zebra mussels
have added to the ecosystem and we just don’t need to take the risk of another one.”
Other researchers agree it’s best to keep the Asian carp out of the Great Lakes. But some say it’s
not a sure thing that the fish would wreak havoc in those waters.
Mark Pegg directs the Illinois River biological station for the Illinois Natural History Survey. He
says the prolific carp might not reproduce as quickly in colder lake waters.
“Fish and a lot of other organisms show a resilience to environmental conditions, so I’m not
gonna say that’s gonna stop ’em dead in their tracks, but it’s certainly an avenue of hope.”
Pegg says it’s also possible that commercial anglers along the Illinois River may slow the spread
of the Asian carp by catching them and selling them.
“Anybody else, would you like to try it?”
Rick Smith is offering small pieces of cooked Asian carp, both regular and smoked. Smith runs
the Big River Fish Corporation in Pearl, Illinois. He says he recently hired some anglers to haul
in some of the invasive fish.
“For two months two crews fishin’ there and we caught almost 200-hundred thousand pounds of
fish in a month and a half and moved em.”
Yep, people bought them to eat. But smith admits that he won’t pay much for Asian carp, until
he’s got a stronger customer demand for them. And he acknowledges that the big fish can be
costly to harvest, because they tend to tear angler’s nets. So government officials say commercial
anglers alone won’t stop the spread of Asian carp. There might have to be more
reinforcements upstream.
A barge passes through the Chicago sanitary and ship canal. The canal connects the Illinois River
system with Lake Michigan. At one place on the bottom of the canal, there’s a system of cables
which electrifies the water. The two-million dollar barrier was originally built to keep the round
goby that’s invaded the Great Lakes out of the Mississippi. Now it’s seen as a way to stop Asian
Carp from getting into the Great Lakes. The electric barrier shocks the fish and is supposed to
stop them from going any farther. But a few months ago, a common carp passed through the
barrier as a barge was passing over it.
Chuck Shea is with the U.S. Army Corps of Engineers. He says the Corps is testing to see if the
steel barges disrupt the electric shock so that fish can get by the barrier alongside the barges.
“So we are going to do a study where we are actually renting barges and running them back and
forth thru the barrier, while measuring the strength of the electrical field with a variety of
equipment.”
Shea says the results of the study could affect the design of a second electric barrier researchers
want to put in a few hundred feet away.
But just getting money to improve the first barrier and build a second one is stalled in
Washington. An invasive species bill could provide millions more dollars for Asian carp control.
But Congress has yet to pass the measure.
Dennis Schnornack chairs the U.S. section of the International Joint Commission. The IJC is an
advisory body that oversees the Great Lakes. Schornack says at one point it looked like the
invasive species bill would pass back in January.
“Well were nearly at the end of 2003 and haven’t seen a committee meeting in either the House
or the Senate, so that’s very disappointing and cause for some alarm.”
And it’s not just the Great Lakes that could be affected. One of the fish was recently caught
along the Mississippi River between Wisconsin and Minnesota, much farther North than the carp
were previously thought to be. So some people are now pushing for a 25 million dollar electric
barrier across the Mississippi, so the carp don’t find their way into places like the Wisconsin and
Minnesota Rivers.

Over time, invasive species have upset the natural balance of the Great Lakes. Now, officials are
working frantically to stop a new threat, the Asian carp. The carp lives in tributaries connected to
the Great Lakes. But there may be another route into the water system – through Asian food
stores. As the Great Lakes Radio Consortium’s Karen Kelly reports, live carp can be purchased
in many cities throughout the region:
“This one in Chinese, layoo. This one in Chinese…”
York Alooah stands in front of a crowded fish tank at the 168 Market in Ottawa, Canada’s capital.
He points to the fat, foot and a half-long bighead carp swimming behind the glass.
The fish are brought to his store by truck from Toronto. They originate at farms in the southern
U.S.
Speaking through an interpreter, Alooah says it’s unlikely that a carp could escape during
delivery.
“They use a big truck and have the fish tank inside.”
Alooah says the fish can’t jump out because the tanks are covered. Still, the live sale of these fish
has many people worried. That’s why states like Indiana, Michigan, Minnesota and Ohio have
banned the possession of live Asian carp.
Several states are also asking the federal government to add these carp to a list of invasive species
considered harmful. That listing would make it illegal to possess them alive.
In Canada, there aren’t laws like that on the looks. But officials say they’re considering action.
Nick Mandrack is a research scientist with the Canadian Department of Fisheries and Oceans. He
says Canadian researchers are keeping an eye on an Asian carp population that’s moving north up
the Mississippi River. They worry that the fish will migrate through a manmade canal into the
Great Lakes.
“If they were to become established, either through dispersal up from the Mississippi or
unauthorized release as a result of the live food trade, they could have enormous impacts on the
Great Lakes ecosystem, which would likely result in a dramatic decline in the biomass of game
fishes.”
That’s because two species of Asian carp eat the same food as small forage fishes. And those
forage fishes are what the larger gamefish rely on. The Asian carp are too big for the gamefish to
eat.
Researchers are also worried about two other species. The black carp could wipe out endangered
mussels that live in the lakes. And the grass carp destroys aquatic plants where native fishes live.
Mandrack has seen both the bighead and the grass carp sold live in Asian food stores. He and
others say that poses one of the greatest threats to the Great Lakes fish population.
(sound of fish scaling)
Back at the 168 market in Ottawa, York Alooah uses a long knife to butcher and scale a fish he’s
pulled out of a tank. He laughs when an interpreter asks if people ever leave his store with live
carp.
“When people buy, it’s not alive. He clean and kill and clean everything.” Is it never alive?”
“Never.”
In fact, the city of Chicago is hoping to guarantee that doesn’t happen. Officials want stores that
sell live carp to operate under permits. And the fish would have to be killed before it left the
store.
But not all fish is bought for consumption. There’s also concern about a Buddhist practice in
which captive animals are released into the wild.
Tookdun Chudrin is a nun with the MidAmerica Buddhist Association. She says the carp sold in
food stores are not likely candidates for release.
“I think that people would not buy such a large fish for liberation because they tend to get very
small animals and very often will put them in a pond at a temple.
And Chudrin says, Buddhists would want to know if the religious practice was harming other
animals.
“I think definitely if there were a sign saying that said putting these fish in the lakes could be
detrimental to other species, I think people for sure would heed that if this was going to endanger
others and the people knew it, I don’t think they’d do that.”
So far, only two Asian carp have been found – in the Canadian waters of the Great Lakes.
Another was released in a fountain in Toronto, just a few blocks from Lake Ontario.
Whether from pranks, or acts of kindness, some fear it’s only a matter of time before more carp
get into the water. They say the Great Lakes could become a giant carp pond, and many of the
species we’ve come to know would disappear.
