Fish biologists are worried about a virus from Europe that is killing fish in the
Mississippi River. Sandra Harris reports:


Spring Viremia is killing carp in the Mississippi River. Biologists are concerned the
virus could spread to other smaller related fish, called cyprinids, that are used for bait. Ron Benjamin is
a fish biologist with the Wisconsin Department of Natural Resources:


“Right now, we’re not seeing that happen. We see the forest base is pretty stable out there. Like I say, it does affect other cyprinids but it’s to various degrees. And so, at least so far, we haven’t seen that impact.”


Benjamin says Spring Viremia was discovered in the Mississippi in 2002 when
antibodies of the virus were found in carp. It is not harmful to humans who eat the fish.
The virus is thought to have been brought to the United States in goldfish imported from
Europe.

Getting Paid to Recycle

  • If you don't recycle, the bin can make a handy shelf. Cities are trying to get people who don't recycle much or at all... to get into the habit by offering them incentives.

Recycling can have some economic benefits. But as a country, we’re
just not doing that much of it. The US Environmental Protection

Recycling can have some economic benefits. But as a country, we’re
just not doing that much of it. The US Environmental Protection
Agency says the national recycling rate has been hovering around 30%
for several years now. Rebecca Williams reports some cities
are trying to get people to recycle more… by paying them to recycle:


It’s not easy getting someone to admit they don’t recycle. But I was
over at my friend Andrea’s house for dinner, and she confessed.


(Sound of Andrea opening a can of beans)


“Normally I would take this can and throw it away in the garbage and
never look at it again. I don’t really like cleaning garbage to throw
it away.”


Now in her defense, she doesn’t really produce that much trash to begin
with. Maybe just one small bag a week.


Andrea says it just feels like too much work to recycle. Taking the
labels off, cleaning out the cans, walking down four flights of stairs.
Though they’re indoors and carpeted.


(Sound of garage door opening)


Right now she’s using her recycle bin as a shelf. She’s got some books
and a quart of oil sitting on it.


If Andrea did recycle, she’d have to drag her bin out to the curb from
the garage. About oh, three feet or so.


“In the mornings I run pretty late so just taking the garbage out and
lugging it down the stairs along with my bags for work is quite a hassle in
and of itself and I’m proud of myself for doing that, so… (laughs).”


Now… my friend can’t be the only one out there who doesn’t recycle.
A recent survey found that 28 states reported a decrease in their
recycling rates since 2001.


That’s not good news for cities, because cities can benefit from
recycling. If they can divert enough recyclables from the waste
stream, they can avoid some of the high costs of disposing waste in
landfills.


But even if you have trucks that drive around and pick up people’s cans
and newspapers from their curbs, there’s no guarantee they’ll put them
out there for you.


Unless, of course, you offer them a reward.


Some cities on the East Coast are paying people to recycle. They’re
using a company called RecycleBank.


With RecycleBank, you get a recycling container with a tracking chip
embedded in it. You can toss all your cans and newspapers and bottles
into that one container… so, none of that annoying sorting.


Ron Gonen is the company’s co-founder.


“There’s a mechanical arm on the truck that picks up your container,
reads the chip, identifies that your household recycled and how much
your household recycled. The amount that your household recycled is
translated into RecycleBank dollars.”


Those RecycleBank dollars can be cashed in as coupons to shop at more
than 300 stores.


“We really look at it from the lens of the recycling industry and that if
your household recycles you’re actually creating value, and some of
that value should be passed back to you.”


Gonen says each family can earn up to $400 a year. He says people are
so into it, they’re even bringing stuff from work to recycle at home.
And he says recycling rates have tripled or even quadrupled in
neighborhoods using RecycleBank.


But some cities have found incentives only work up to a point. So
they’re making it against the law not to recycle. Seattle, for
example, won’t pick up your trash if there’s stuff in it that could be
recycled.


Timothy Croll is Seattle’s Solid Waste Director. He says trash
collectors aren’t going through trash cans, but they are peeking in.


“It’s not like we’re taking these things into an MRI or anything like
that it’s just what the garbage collector can see at the top when they
open the lid.”


Croll says the law works. He says only a few trash cans have been left
behind with a note. And Seattle did try incentives first. The city
charges residents less for trash collection if they use a teeny little
trash can and recycle a lot more. Croll says that’s been pretty
successful. But he says the city wanted to push for even more
recycling… so, they made it a law.


“Some tools work better for some people than others. For some people
it might be they know it’s the right thing to do, but their lives are
busy, and unless you give them one more reason they’re just not going
to get over that threshold and do it. It’s like yeah I know, I know I
should floss too, you know?”


Croll says it’s up to cities to first make recycling convenient… And
then try sweetening the deal.


You know, my non-recycling friend DOES recycle her soda cans. She
lives in Michigan, so she gets 10 cents back for each one. It’s enough
of an incentive that she’s saving bags of cans at work and stashing
cans in every corner under her kitchen sink.

Fish and Wildlife Service to Cut Staff

More job cuts might be on the way at National Wildlife
Refuges, but the new Congress will apparently be taking a
closer look at reductions announced by the US Fish and
Wildlife Service. Chuck Quirmbach reports:


The fish and wildlife agency already has announced plans to
cut more than 250 jobs over the next three years. Further
cuts are expected soon.


The agency blames a flat budget and rising operational and
personnel costs, but Jeff Ruch of Public Employees for
Environmental Responsibility says visitors to the affected
refuges will find a less enjoyable experience at no real
savings in tax dollars:


“All the cutbacks in the refuge system are less than what
we’re spending in Iraq in a day. I mean to put it in some
perspective, we’re talking about literally millions of
dollars versus billions of dollars that are being
hemorrhaged out of other government operations.”


Democratic Congressman Ron Kind co-chairs a caucus on
wildlife refuges. He says he’ll try to address the job cuts
in the next federal budget.

Blazing New Atv Trails in Parkland

  • Advocates of special trails for ATV riding say the trails would reduce environmental damage from uncontrolled use. (Photo by Stephanie Hemphill)

Managers at state parks across the country are scrambling to figure out how to deal with a
rising demand for trails for All-Terrain Vehicles. Stephanie Hemphill reports park

Managers at state parks across the country are scrambling to figure out how to deal with a
rising demand for trails for All-Terrain Vehicles. Stephanie Hemphill reports park
managers are finding it’s not easy to satisfy both fans who have fun on four wheel drive
vehicles and people who want a quieter time in the park:


As the name suggests, All-Terrain Vehicles are built to travel rough. ATVs power over
rocks and logs. Their go-anywhere knobby tires grip the land and take their riders just
about anywhere they want to go, and a lot of them want to go to public parks.


Whether it’s forests, dunes, bogs or a desert, riders say four-wheeling can be a fun way to
get out into nature. The vehicles are popular. Dealers are selling close to a million ATVs
every year, and sales are growing steadily. With that many people looking for a place to
play, states are scrambling to accommodate them.


In Minnesota, the state decided a long ATV trail might be a good way to attract tourism
dollars to a struggling rural area in the state.


Ron Sluka jumped at the idea. He’s the trail coordinator for a local ATV club. He’d been
wanting for years to build a trail in his area. Then he heard the state would pay for a
“destination” trail so well-built and attractive, people would come from all over to ride it.
Sluka thought it would be great news for his area.


He and county officials worked up a plan, but when it hit the local news, Sluka says a
few people raised a ruckus:


“The way it was presented to the people, eminent domain would take over in cases if
need be, and there were going to be up to 20 feet of your land taken for this trail. None
of the above is true, totally none of it is true, absolutely zero. But it’s too late: once
things are rolling, it’s rolling.”


Sluka says now, it’s hard to get a rational discussion of the issues. Beyond property rights
issues and worries about the ATVs being too loud, there are other concerns:


“The residents have kind of been left out of the loop.”


That’s Deb Pomroy. She lives near the proposed ATV trail.


Pomroy says most of her neighbors don’t mind the local ATV riders. It’s that idea of
drawing ATVs from all over the state that freaks them out, and Pomroy has her own reasons
for opposing a trail here, where the Cloquet River has its beginning: wood turtles.
Pomroy is a biologist. She says this area is a refuge for the turtles. They’re endangered in
most of their range, and listed as a threatened species in Minnesota.


Wood turtles bury their eggs in sandy soil. Pomroy says they would love to bury their
eggs in soil disturbed by ATVs, but the eggs wouldn’t survive:


“Even stepping on a nest, which is buried in soil, don’t know there are eggs there, is
enough to destroy the eggs.”


The trail is on hold for now, while county officials and ATV riders try to come up with
an alternative. Concern about damage to sensitive environmental areas is one of the chief
reasons many environmentalists don’t like the idea of letting ATVs into parks.


Jason Kiely is with Wildlands CPR, a national non-profit group that works to prevent off-
road vehicle damage on public land. He says fights over ATV trails are inevitable, as
long as public agencies don’t involve all park users in a comprehensive planning process.


“Primarily because off-road vehicles affect every other use of the forest so significantly.
So we advocate for doing comprehensive travel and recreation planning, not just trying to
carve off the ATV piece, but multi-stakeholder planning efforts that offer something to
everyone.”


Kiely says the US Forest Service and many state agencies have a lot of work to do, to
find the right balance between preserving nature and allowing ATV riders to have their
fun on public land

Windmills Generate Jobs and Power

U.S. demand for clean energy is growing fast. In fact, wind energy developers are ordering so many windmills, they’re running into a supply problem. Windmill manufacturers overseas have been shipping their products to the booming U.S. market. That’s already created some jobs, and now there are plans to build factories to produce windmills here. It’s all happening in spite of inconsistent federal support. Stephanie Hemphill reports:

U.S. demand for clean energy is growing fast. In fact, wind energy developers are ordering so many windmills, they’re running into a supply problem. Windmill manufacturers overseas have been shipping their products to the booming U.S. market. That’s already created some jobs, and now there are plans to build factories to produce windmills here. It’s all happening in spite of inconsistent federal support. Stephanie Hemphill reports:


At the Duluth Port Terminal, the BBC India is tied up to the dock. Two giant cranes slowly lower a silvery propeller onto a waiting truck. The blade is half as long as a football field. The extended bed of the eighteen-wheeler isn’t long enough to hold the entire length. A padded steel structure cradles the narrow end above the ground. There are 66 blades on the ship, three blades for each of twenty-two towers.


“The three blades will bolt into a hub, and then the hub attaches to the nacelle, the generator package, that’s the actual turbine, and the nacelle sits on top of the tower.”


Andrew Holdrup is the port captain for the shipping company. He was here in Duluth a year and a half ago, when the port handled its first ever shipment of windmills.


Holdrup says the demand for windmills is huge in the U.S.


“We have four ships; all they do is run from Denmark to Houston with Siemens windmills. We discharge them in Houston, the ship sails back empty to go pick up the next lot. Multiply that by all the other ports, and all the other windmill manufacturers, and it’s a huge business.”


It’s great business for Duluth’s port. Unloading the windmills requires iron workers to cut the steel where the pieces have been welded to the ship, and crane operators, and longshoremen. And truckers are staying in town waiting to pick up their loads. They’ll haul the windmills to wind farms being built in Mower County, Minnesota, and Oliver County, North Dakota. The port has also handled equipment for wind farms in Manitoba.


The boom in wind was primed in the early 1990s, when Congress set up a production tax credit for wind power. It allows a 1.9 cent-per-kilowatt-hour tax credit over ten years, for electricity produced by wind.


But the tax credit only runs for two years at a time. Ron Johnson is in charge of marketing for the Duluth Port Authority. He says that on-again, off-again approach has made it hard for businesses involved in wind energy to plan and grow.


“It’s kind of start up again, stop, start up again, stop. If you’re a trucking company with these specialized trailers, you don’t want to go out and buy fifty more of them if there’s a chance your whole fleet’s going to sit until Congress decides what to do.”


Johnson says there’s a lot of support in Congress for the tax credits, and he expects them to be renewed.


Steve Stengel works for FPL Energy, the company building the wind farms where these windmills are headed.


“It is part of the business, we understand that. And it does cause kind of starts & stops, if you will.”


But he says it’s possible to work around the periodic breaks in the tax credit because it takes a long time to plan a wind project anyway.


“Permitting issues, land lease issues, transmission issues. We have to plan as if the tax credit is going to be there.”


In fact, wind is growing dramatically in spite of the iffy nature of federal support. Several states now require utilities to invest in renewable energy, or offer incentives for wind power development. And as the cost of fossil fuels goes up, the relative cost of wind goes down.


It all adds up to a lot of demand, and recently, tight supplies.


The American Wind Energy Association’s Susan Sloan says orders are already in place for 2008 and beyond.


“Because of this boom and bust cycle but also because of this new acceptance of wind, we are seeing a tighter supply, and we need to have the manufacturing capabilities catch up.”


And that’s what’s happening.


It took two weeks for the Siemens windmills to sail from Denmark to Duluth. Now the company is building a factory in Fort Madison, Iowa. Siemens says it will employ 250 people, and start producing in the first half of 2007.


And in Pipestone, Minnesota, Suzlon, a company based in India, is about to start producing three blades a day, and the nosecones to go with them. The company plans to manufacture the electronic controls, and eventually employ up to 300 people. Suzlon says it has orders for the next two to three years.

US demand for clean energy is growing so fast, supplies of generating systems are getting tight. Stephanie Hemphill reports on a challenge that could lead to more jobs in the US:


Overseas manufacturers of wind generating systems are shipping them here as fast as they can. Now, several companies are building wind generator factories in the US.


Siemens is building a plant in Iowa. Suzlon is about to start production in Minnesota. Plants in Texas produce blades and towers.


It’s all happening in spite of inconsistent federal support. A production tax credit is in place, but it expires every two years.


Ron Johnson is with the port of Duluth, which handles windmill imports. He says the on-again, off-again support makes it hard for companies to plan and grow.


“Well, the deadline’s coming at the end of next year, and people are planning their projects, so we’re all anxious to see what Congress does.”


The American Wind Energy Association says producers are installing enough wind power this year to power the entire state of Rhode Island.

The Costs of Preventing Flood Damage

  • A shed in Valmeyer, Ill. shows how high the water got during the 1993 Flood. The flood waters caused such damage that most of the town moved a few miles east, high up on a bluff. A few residents and many farmers, though, stayed in the flood plain. (Photo by Tom Weber)

It’s been 13 years since the Great Flood of ’93 caused widespread destruction along the upper Mississippi River. After the flood, there was talk of needing to expand the natural floodplain by eliminating levees that protect farmland. That didn’t happen. In fact, not much of anything has happened, but that doesn’t stop farmers from wondering if the government will buy their farms and turn them into natural areas designed to take the waters of the next big flood. Tom Weber reports:

It’s been 13 years since the Great Flood of ’93 caused widespread destruction along the
upper Mississippi Rivers. After the flood, there was talk of needing to expand the natural
flood plain by eliminating levees that protect farmland. That didn’t happen. In fact, not
much of anything has happened, but that doesn’t stop farmers from wondering if the
government will buy their farms and turn them into natural areas designed to take the
waters of the next big flood. Tom Weber reports:


For all the river talk in these parts, it’s actually kind of hard to see the water. Doug
Sondag’s farm is about about two miles from the river and his view to the west
is of the bluffs, on which Missouri towns, like Herculanium, sit.


“That’s Missouri bluffs. That’s Missouri bluffs, and to the north the bluffs that you see is Missouri.
We’re on a big bend here.”


Doug’s friend Ron Kuergeleis is visiting the farm today. Kuergeleis lost his home in the
’93 flood, but he still farms on the flood plain near Valmeyer, Illinois. The two also are
commissioners with the local levee district, which means they’re in charge of keeping the
local levee up-to-date so the river is kept away.


Today, though, they’re talking about the possibility of a new federal levee and something
called “Plan G.”


(Ron): “You’re talking quite a few farmers that would absolutely put them out of
business. You’re one of them, I’m one of them, and there’s – (Doug): “There are quite a few
more.” (Ron): “There are quite a few more.”


No one is going out of business any time soon, though. Plan G is something the Army
Corps of Engineers studied and decided wasn’t worth the money. It would have the
Corps spend billions building up bigger levees along the upper Mississippi to 500-year
levees: the highest levees the Corps builds.


Plan G also would create a huge storage district nearby. A storage district is a kind of
relief area where flood waters go to take strain off other levees. Corps engineer Richard
Astrack says design elements like these can help control flooding in other places:


“Now we have the capability that we didn’t have before to look at whole system to ensure
that actions taken at one location can impact another location.”


The Valmeyer storage district would require a new levee in the flood plain, which would
leave 10,000 acres of currently protected farmland unprotected and on the wrong side of
the levee.


This all started a few years ago, when Congress told the Corps to study the entire Upper
Mississippi River, from Illinois’s southern tip to Minnesota, find out if the current levees
are good enough to reduce flood damage. If not, should there be some comprehensive plan to guide just which levees get built up and when? Such a study actually had never been done.


The Corps’ Richard Astrack says they looked at a lot of options, including that Plan G,
to see if any of them were worth the time and money. And it turns out, none of them is:


“None of the plans passed that test. Our draft report does not
recommend any systemic plan.”


And the Corps’s final report will probably recommend essentially doing nothing because
the current system does a good enough job of preventing flood damage. The Corps will
recommend updating, but not raising, current aging levees, and also creating some mini-
levees to protect roads that approach bridges.


But even with all the assurances that Valmeyer, Illinois is safe for now, farmers in the
bottomlands are worried that the federal government might one day force their children
or their grandchildren off their farms.


Ron Kuergeleis is a fourth generation farmer:


“We’re pretty much assured in our lifetime it ain’t gonna happen. But some of us got another
generation coming up and you don’t know. He claims, you know where you going to
come up with money, but if they want to come up with it, they’ll find it.”


The worries stem from the fact that Corps cannot, in all fairness, guarantee that such a
levee would never be built. Because setting aside some of the bottom lands for natural
flooding could protect big cities such as St. Louis, Missouri and Memphis, Tennessee,
there’s concern that Congress might one day instruct the Corps of Engineers to buy out
those farms.


So, while Valmeyer is not getting a new levee right now, the people here say they’ll keep
working to stay one step ahead to make sure it never happens.

Battle Over the Right to Grow Rice

  • Roger LaBine winnows the wild rice. (Photo by Michael Loukinen, Up North Films)

Since European settlers first came to this country they have had serious conflicts with Native Americans. The GLRC’s Sandy Hausman reports on one modern-day dispute between a Native American tribe and communities in the upper Midwest:

Transcript

Since European settlers first came to this country they have had serious conflicts with
Native Americans. The GLRC’s Sandy Hausman reports on one modern-day dispute
between a Native American tribe and communities in the upper Midwest:


(Sound of Ojibwe music)


The Ojibwe tribe first came to the north woods of Michigan and Wisconsin hundreds of
years ago. They say their migration from the east coast was guided by prophets. Those
prophets told them to keep moving until they came to a place where food grows on the
water. Roger Labine is a spiritual leader with the tribe. He says that food was wild rice:


“This was a gift to us. This is something that is very, very sacred to us. This is very
important, just as our language. This is part of who we are.”


For hundreds of years, wild rice was a staple of the tribe’s diet, but starting in the 1930s,
private construction of hydroelectric dams pushed water levels in rice growing areas up.
High water killed most of the plants and took a toll on wildlife. Bob Evans is a biologist
with the U.S. Forest Service. He says fish, bird and insect populations dropped
dramatically:


“Black tern is a declining, threatened species that is known to use wild rice beds,
Trumpeter swans. They’re a big user of rice beds. Um, just a whole lot of plants and
animals. It’s really a whole ecosystem in itself.”


So in 1995, the tribe, the U.S. Forest Service and several other government agencies
demanded a change. A year later, the federal government ordered dam operators to drop
their maximum water levels by 9 inches. The dam owners appealed that decision, but in
2001 a federal court ruled against them.


That fall, the Ojibwe who live on Lac Vieux
Desert harvested nearly 16 acres of wild rice and this summer, the tribe is tending more than 55 acres.
But the resurgence of rice beds comes at a price. Lower lake levels have left docks in this
boating community high and dry, created muddy shorelines and made long-time residents
and summer boaters angry:


“I used to come here and dock all the time. We picnicked here. I had to walk in 50 feet,
because there wasn’t enough water to float a pontoon, and it’s that way all around the
lake.”


Ken Lacount is president of the Lac Vieux Desert homeowners association. He first
came here in the 1940s and doesn’t see why his cultural traditions should take a backseat
to those of the Ojibwe:


“My grandfather built one of the first resorts. I fished in Rice Bay my entire life. That
was his favorite place to take me.”


Lacount is bitter. He and his neighbors feel powerless to change the situation, since a
federal court has ruled for the Ojibwa. Defenders of that decision say water levels are
especially low because of a prolonged drought in region. When that ends, they predict
lake levels will rise, and homeowners on Lac Vieux Desert will be happier.


(Sound of paddling)


Such conflicts are nothing new. Ron Seeley is a reporter for the Wisconsin State Journal. He’s covered Native American issues for more than 20 years. Paddling through the rice beds, he recalls an earlier battle
over fishing rights. In the late 80s, a court ruled the Ojibwe were entitled by treaty to
spear fish each spring. Local fishermen worried the practice would destroy their industry:


“Sometimes thousands of people would show up at the landings on a spring night. Tribal
members from all over the upper Midwest would come to support the spearers and drum
and chant. The anti-Indian forces were arrested for using wrist rockets or real powerful
sling shots to shoot pellets at the tribal members while they were out spearing. It was a
violent time up here.”


As court after court upheld the rights of native spear fishermen, and as commercial
fishermen continue to prosper, hostilities subsided and now, as the Native Americans prepare for
their biggest rice harvest in more than 50 years, the Ojibwe hope that the controversy over water levels
will also die down. Tribal leader Roger Labine says wild rice is a symbol of the Ojibwe’s survival:


“This is an endangered species. It’s something that we’re fighting to save, just like the
eagle, just like the wolf. We were put here to care for Mother Earth and all the gifts that
the creator gave us.”


And having won the first battle to restore rice beds, Labine is hoping to secure even
greater protection for these wetlands by asking the federal government to declare the rice
beds historic.

Sturgeon Spearing Season Underway

Sturgeon spearing season is underway in some areas of the region, and hook
and line fishing is allowed at other times of the year, but to protect the
fragile population, the number of fish harvested each year is tightly
controlled. The Great Lakes Radio Consortium’s Christina Shockley
reports:


Over-fishing and habitat problems have plagued the lake sturgeon found
in the Great Lakes. Although the numbers are starting to rebound, the
U.S. Fish and Wildlife Service says lake sturgeon are still threatened or
endangered in nearly all areas the species was once found.


Ron Bruch is a sturgeon biologist with the Wisconsin Department of
Natural Resources. He says the spawning cycle of lake sturgeon is one
reason the population needs to be watched.


“Lake sturgeon don’t spawn until later in life, the females don’t spawn
until they’re 20 to 25 years old, and then they only spawn once every
three to five years.”


Bruch says only about five percent of the adult population of lake
sturgeon should be harvested each year… to avoid a population crash.
He says that compares to nearly 30 percent of the population of most
other game fish.

Ten Threats: Saving an Ancient Fish

Biologists have been concerned about a number of native species that
have been disappearing. One of them is the largest fish in the Great
Lakes. Over-fishing and gravel mining in riverbeds have wiped out 99-
percent of the population of lake sturgeon. Sturgeon used to be common
throughout the Great Lakes, but they’re a rare sight these days. Celeste
Headlee reports… biologists are trying to save some of the sturgeon’s
spawning grounds:

Transcript

We’ve been bringing you reports from the Great Lakes Radio
Consortium’s series ‘Ten Threats to the Great Lakes.’ Lester Graham is
our guide through the series. He says our next report is about an ancient
fish that’s been disappearing.


Biologists have been concerned about a number of native species that
have been disappearing. One of them is the largest fish in the Great
Lakes. Over-fishing and gravel mining in riverbeds have wiped out 99-
percent of the population of lake sturgeon. Sturgeon used to be common
throughout the Great Lakes, but they’re a rare sight these days. Celeste
Headlee reports… biologists are trying to save some of the sturgeon’s
spawning grounds:


(Sound of the lake)


Sturgeon are the largest fish in the Great Lakes. The grayish brown
creatures can grow up to seven feet long, and weigh more than 200
pounds. Sturgeon have been on Earth for 100 million years, and they’ve
remained essentially unchanged in all that time. Instead of scales, the
fish have an almost leathery skin with five rows of bony plates running
along their torpedo-shaped bodies.


Fish biologist Bruce Manny says sturgeon were once abundant in the
Great Lakes. Back in 1880, in one month’s time, fishermen pulled four
thousand of them from the Detroit River.


“They tore holes in their nets when they were fishing for other fish that
they cared about. So, when they found a sturgeon in their nets, they
would kill them, bring them to the shore, pile them up on shore, dry them
out and use them for fuel in the steamships. Burn them up.”


Most of the time, the creatures were caught and killed while fisherman
angled for more valuable fish. Scientists think over fishing has caused
sturgeon populations in all of the Great Lakes to dwindle to less than one
percent of their former number.


The state of Michigan closed the Detroit River to sturgeon-fishing years
ago. Bruce Manny says he decided to check on the sturgeon and see if
the fish population had started to recover.


Manny assembled a team of biologists from the U.S. Geological Survey.
He says he was surprised when his team caught only 86 fish over the
course of four years. Manny says he realized the sturgeon were in
serious trouble.


USGS scientists followed the tagged fish for two years, and their
patience was eventually rewarded. Manny found the first known
spawning site ever documented in Detroit River in modern times.


“We were excited all right. Eureka moment. I mean this is like a very,
very great coincidence that we were able to find these spawning ready
males, and they were able to find a female. When there are only 86 fish
caught in four years out here, there aren’t that many around. So, to find
someone to spawn with is a real challenge, I would say.”


The area where the sturgeon mated lies close to a sewer discharge pipe.
There are limp, brown grasses bordering grey, mucky water. Manny sent
divers down and discovered the fish had actually produced fertilized
eggs. Manny says this was a major step forward for his project.


Sturgeon are pretty picky about their nesting sites. They need a fast
moving current and several layers of rock where eggs rest safely. The
problem is a lot of the gravel has been mined out of the Detroit River for
use in construction.


Another problem is the sturgeons’ long life. Fish biologist Ron Bruch is
in Wisconsin. He oversees sturgeon populations in Wisconsin’s
Winnebago river system. He says female sturgeons live more than 100
years and they don’t spawn until they are at least 20 years old.


“Their life history works well for a long-lived species, but it doesn’t
work well for a species that’s exploited heavily. So, sturgeon can only
tolerate very low exploitation rates, and when that exploitation is high
the populations collapse.”


Wisconsin was the first state in the U.S. to create a sturgeon management
program more than 100 years ago, and the fish are more abundant there.


Biologists in Michigan monitored the nesting sites in the Detroit River
this spring. Eight species of fish used the beds, including popular sport
fish like yellow perch and walleye. Only two sturgeon came by the sites,
but they weren’t ready to spawn.


Ron Bruch says biologists will have to create a lot more spawning sites
like the ones in the Detroit River before the sturgeon population is firmly
reestablished in the Great Lakes.


“In and of itself, it’s not going to restore all of Lake Erie or all the Great
Lakes, but it’s a shining example of what can be done in many areas
around the Great Lakes to help produce Lake Sturgeon spawning habitat
and rehabilitate the Lake Sturgeon population.”


USGS biologists will go back to the nesting sites next spring. They say it may
take years for sturgeon to notice the small beds in the 32-mile river.


One important development, though, is a change of policy from the
Ontario Ministry of Natural Resources. Canadians used to allow
fisherman to take one sturgeon a day out of the river. Now, it’s illegal to
possess one of the endangered fish on both sides of the channel.
