People who love to fish spend plenty of money on gear, license fees and even gas for their boats. It’s enough to make anglers think, maybe they’re entitled to keeping the biggest fish for trophies or the frying pan, right? Shawn Allee met a researcher who wants you to throw back your biggest catch:

This is the guy who wants to change how a lot of people fish.

“My name is Paul Venturelli and I study fisheries biology at the University of Toronto.”

Venturelli’s disturbed by how many fish species are on the brink of collapse – either in oceans or in fresh water.

He hopes to grow fish stocks – with this fishing advice.

Toss the big ones back.

And what’s he got to back that up?

“I’ve got about ten pages of notes here. Nah, I’m kidding. I’m kidding.”

Actually, he says the idea is pretty simple.

“A ton of big, old fish will produce more new fish than a ton of smaller, younger fish. And this is because the bigger, older fish tend to produce offspring that have a higher chance of survival.”

Venturelli studies mostly ocean-species, but he says the principal should apply to North American freshwater fish like pike and walleye, too.

But Venturelli’s got a problem spreading this idea around.

Fishing laws in Canada and a lot of US states often protect small fish and are less restrictive with big ones.

I asked one of the head guys in Illinois fisheries, Joe Ferencak, why that is.

“Essentially what you’re doing with that minimum size limit is protecting one or two year classes of reproductive age fish so they can successfully spawn or reproduce.”

Ferencak says, fisheries science has stood behind the ‘protect the small fish’ theory for decades – with some exceptions.

He says to change laws, Venturelli would need to do more studies.

Plus, Ferencak says no state would want to completely keep people from big fish – that’s just not much fun.

“We want to maintain and enhance these fisheries for the benefit of the fishing public, the angler. And it’s kind of counter-intuitive to not allow them to take these larger fish.”

Well, I figure it wouldn’t be fair to talk about big fish without talking to outdoorsmen, so I spent some time in Griffith, Indiana.

It’s about ten miles from Lake Michigan.

Fishing and hunting outlets are all around – and there’s this place.

Allee: “So what’s the establishment.”

Leap: “American Natural Resources.”

Edward Leap Senior runs American Natural Resources – it’s a taxidermy shop – with stuffed deer, fox, and fish filling every nook and cranny.

I figure Leap would rush to the defense of catching big fish, but, you know what? He doesn’t bite.

Allee: “If you get a whole bunch of fish in your boat, I mean, you want to show off the big one. Most people do, right?”

Leap: “Yes and no, though. When you get talking about the conscientious outdoorsman, no, he’s not going to be thinking this way. He’s going to say, ‘I got this fifteen pound walleye, a super-trophy fish. It took a lot of years to grow this fish, I’m going to take a picture of it and I’m going to release it.'”

And, to prove the point, he reaches back and pulls a fish trophy off the shelf.

“For the trophy part of it, we’ll do a reproduction of it that you can’t tell from the real thing. And the fish now is out there spawning, and making eggs, and continuing its species.”

Leap says more and more fishermen are having him make fake fish – or, reproductions, as he calls them.

So, from his vantage, scientists like Paul Venturelli won’t have too much trouble with the advice to ‘throw back the big ones.’

Leap says you don’t have to keep fish you catch, and in his experience, smaller fish make better eating anyway.

Most nuclear power plants are huge
multi-billion-dollar operations that take
ten years to build. But they can be much
smaller. Lester Graham reports on a company
that’s planning hot-tub sized reactors:

It’s difficult to get political and financial backing for building big nuclear power plants.
But one company plans to build miniature nuclear reactors.

John Deal is the CEO of Hyperion.

He says the small reactor invented at the Los Alamos National Laboratory could be
useful for isolated areas. It could also be used by smaller cities to provide most of
their power needs.

“You might have a community of 20, 30, 40 thousand people and they can have their
own power plant. And then they might feed back their excess or draw down from
some centralized facility for when they’ve got power spikes or peak demand.”

There’s a lot of interest. But for right now Hyperion is not taking orders for the mini-
nukes from Western nations. Deal says Hyperion is first trying to bring power to
isolated areas in the developing world.

Small Car Trend to Stay?

When gas prices went up, car
companies cut their production plans for
making big vehicles, and made new plans
for more fuel efficient cars. The question
now is, with gas prices falling, will those
plans change again? As Dustin Dwyer
reports, the experts say probably not:

It’s not as easy to make money on a small car as it is on an SUV.

Small cars are cheaper, and they have lower profit margins. But as gas prices went up earlier this year, auto
executives insisted they’d find a way to make money on small vehicles.

Since gas prices have dropped though, some buyers are showing more interest in big vehicles.

Michael Robinet tracks the auto industry for the firm CSM Worldwide. He says the long term trend still
points to smaller vehicles.

“There may be a ratcheting down by some consumers in terms of the size of vehicles that they’re looking
for, irrespective of where fuel prices go in the future.”

Robinet says the bad economy is forcing many people to downsize. And the federal government has new
rules that mandate cleaner cars, so Robinet says getting smaller will be the big trend for years to come.

Recycling on the Farm

Over the last 30 years, plastics
have become indispensable on America’s
farms. They save farmers time and money.
The problem is agricultural plastics are
filling up landfills. In some places,
farmers actually burn the plastic. That
releases dangerous chemicals into the air.
David Sommerstein reports
on a new effort to bale plastics and recycle
them:

Farmers must have been paying attention when Dustin Hoffman got that
famous piece of advice in ‘The Graduate’.

“I just want to say one word to you, just one word.”

“Yes, sir?”

“ Are you listening?”

“Yes, sir, I am.”

“Plastics.”

Plastics are all over the farm today. Plastic greenhouse covers. White sheets
to wrap hay bales. Black plastic feed troughs.

(sound of moving troughs)

Dale Tetreault shakes a tall pile of the feed troughs on his dairy farm in
northern New York State.

“They’re a hard plastic and they hold molasses and minerals.”

Tetreault says the plastics are handy – essential, really – to keep feed fresh
for his 500 cows. But the material’s hard to re-use because it gets dirty and
tears easily.

So Tetreault’s left with a decision – spend a thousand dollars a year to truck
them to the landfill. Or burn them, polluting the air and water.

“Yeah, exactly, I mean, we’re not talking about some light piece of plastic
here. We’re talking about heavy duty plastic.”

A new machine is giving Tetrault a third alternative. It goes by the name of
Bigfoot.

(sound of motor starting up)

Bigfoot is a portable hydraulic press. It crushes used plastic and ties it up
in bales.

“Quite an interesting contraption, that’s for sure.”

Tetreault’s been saving up used farm plastics for a couple months for this
test run.

“Alright, we ready to try this?”

That’s Steve Mahoney, a farm educator with the local soil and water
conservation district. He bought Bigfoot with a $35,000 state grant.

(sound of engine running)

Mahoney and some farmhands stuff dirty plastic sheets into the baler, then
Bigfoot crushes it down. That makes room for more.

(crushing sound)

“Okay, so go on back up.”

Mahoney teaches the farmhands how to run Bigfoot. With the help of the
local farm extension office, he’s baled plastics at nine farms so far. He
wants all of the area’s farmers to share Bigfoot, to keep plastics out of the
landfill or burn pile.

“It’s an obvious problem on the farms. It’s necessary, but the disposal of it
is a problem.”

The big plan is to recycle the plastic. Mahoney’s coordinating with a
recycling firm in Minnesota to pick up 40,000 pounds of plastic bales. They
could be made into plastic lumber or shingles or road filler.

The thing is, there isn’t much of a market for low-grade, dirty plastic right
now. Lois Levitan directs New York’s Ag Plastics Recycling Project at
Cornell University. She says as fuel costs rise and more farmers bale their
plastic, that might change.

“Markets want to know that there’s a certain quantity of product at a
certain level of quantity and they’re going to become increasingly interested
when they know there’s a steady stream.”

(sound of Bigfoot machine popping out a bale)

“Ok, that’s it, that’s the finished product.”

Steve Mahoney presses a button and out pops a thousand pound bale of
plastic. Farmhand Lennie Merculdi brushes his hands.

“Put it this way, trying to put it in a dumpster, to the barn, and never having
enough room for the garbage, that’s not good either. What’s a few minutes?
You get rid of the plastic, it’s convenient, you tie it up and away it goes.”

Dead Zone to Reach Record Size

Transcript

A researcher is predicting farm
fertilizers will cause record “Dead Zones”
in the Gulf of Mexico and Chesapeake Bay
this year. Lester Graham reports:

These dead zones are areas where oxygen is depleted. No oxygen and much of the
marine life leaves or dies. It’s caused by nitrogen-based farm fertilizers that are
washed off the fields and into the water.

Donald Scavia is a researcher at the University of Michigan. Using U.S. Geological
Survey data, he predicts the dead zone in Chesapeake Bay will be the sixth largest
on record.

“The six other ones are also not that much bigger than what we’re predicting for this
year.”

Heavy rains and flooding across the Corn Belt washed nitrogen fertilizers into the
Mississippi River system and then on to the Gulf of Mexico. Scavia predicts the
dead zone in the Gulf could be the largest ever.

“What you put down on the land is what gets flushed in those rainstorms. And we’re
putting too much fertilizer on the land. So,
what’s changed over the last three decades is agricultural practices. What changes
from year-to-year is the weather.”

Scavia says better methods of farming could reduce the dead zones.

Keeping a Big Fish From Butting In

  • Asian Carp can grow up to 110 pounds (Photo courtesy of the US Fish and Wildlife Service)

There are invasive fish swimming their
way toward the Great Lakes. If they get in,
they could swallow up a multi-billion dollar
sport fishing industry. Mark Brush reports,
officials are investing millions of dollars
to keep Asian Carp out of the Great Lakes:

Asian Carp were imported by fish farms in Mississippi and Arkansas to control algae.
But the fish escaped during floods. They swam out of the fish ponds, and into the Mississippi
river. And they’ve been moving north ever since.

(sound of boats)

Thad Cook is on a tributary of the Mississippi River in Illinois. This river is more than
400 miles upstream from where Asian Carp first escaped the fish farms.

Cook is looking
for two types of Asian Carp known as Silver and Bighead Carp. It turns out t’s not hard to find them. He dips an electrified pole into the water – and the fish jump right out of the
river and into the boat.

(sound of fish flopping in boat)

Cook is with the Illinois Natural History Survey. His group, along with several others,
has been making trips like this one for years. They’ve been keeping a close eye on where
the fish are going. He takes a guess at how big this fish is.

“No he’ll go… uh.. he’s probably…”

“Hold him out there Jimmy!”

“Yep, six, seven, eight, nine, ten pounds.” (Laughter)

His fish story could have gone a lot further. Some types of these Carp can get up to a
hundred pounds. There aren’t many fish that can compete with an appetite like that.

Biologists are finding that these carp are pushing native fish species aside as they spread
north through the Mississippi River system. And some fear it’s only a matter of time
before they swim their way into the Great Lakes.

David Jude is a fisheries biologist with the University of Michigan.

“I’m very concerned about what impact they would have in the Great Lakes because
they’re planktovores which means they filter zooplankton from the water column. And, they’re just huge fish. And so they have the potential for having
a tremendous impact on our ecosystems.”

He says the silver and bighead carps are filter feeders. They pass up eating smaller fish –
and head straight for the bottom of the food chain.

Jude says if Asian carp get in, it’ll make a bad situation worse. The Great Lakes are
already losing zooplankton from other invasive species. Asian Carp could
destroy a 4 billion dollar a year sport fishing industry.

(sound of canal)

And here is where the battle line is being drawn. The fish have been spotted thirty miles
downstream from this spot on the Chicago Ship and Sanitary Canal. A century ago,
engineers blasted through solid rock to connect the Great Lakes with the Mississippi
River system.

Chuck Shea is with the U.S. Army Corps of Engineers.

“Any type of fish that would want to move between Lake Michigan and the Mississippi
river basin – has to pass through the Chicago Sanitary and Ship Canal – there’s no other way to swim through. So, they have to come through this body of water we’re standing in front
of right now.”

Shea is in charge of the construction and maintenance of two electric fish barriers along this canal.
When this barrier is online, machines will pulse electricity into the water. The electric current shocks
the fish – making them swim away.

This barrier hasn’t been turned on yet. There have been delays due to funding shortages. And they’re still
doing safety testing with the Coast Guard.

Right now, the only thing that would keep the carp from getting into the Great Lakes is a temporary electric
barrier built six years ago.

The good news is that there still seems to be a little time. Biologists say, so far, Asian Carp haven’t moved any
closer than thirty miles from the barrier for the last couple of years.

Bigger Not Always Better

In many areas of the country, small farms
are now the exception, not the norm. Farming,
especially with livestock, can mean thousands and
thousands of animals, and often distant, corporate
ownership. Even the smallest farms are pressured
to get bigger. So when a family decides to make
their farm smaller, they’re rebels. Kinna Ohman
reports:

It’s five o’clock in the evening on the Hill’s dairy farm. Ray Hill just finished cleaning
out the milking equipment and is moving into the barn.

(sound of milking equipment and door)

Cows look around curiously, and afternoon light streams through the windows. Hill
moves comfortably among these cows, calling each of them by name, and cleans their
udders for milking.

(Ray describing the process)

Ray Hill and his wife Stephanie are full time farmers. They milk ten cows, twice a day.
They sell raw milk and yogurt directly from their farm. But getting to this point hasn’t
been easy. To survive, they’ve had to step away from the conventional approach to dairy
farming.

When the Hills got into farming eight years ago, they listened to the advice of farm
experts. They had more than forty cows, a tractor, and were selling their farm’s milk to the
regional processors.

But within a couple of years, they were deep in debt. Hill says the experts told him to get
more cows. He says he couldn’t see how that would help.

“Financially it just didn’t work. There wasn’t money to hire help. I had a couple of
kids and my wife and we were all running ragged and it just wasn’t fun. And there
were many days where I threatened to sell every cow in the barn.”

It’s common for farm experts and even bankers to push family farmers like the Hills to
‘get big or get out.’ Darrell Emmick’s with the Natural Resources Conservation Service.
He says he’s seen regions lose more than fifty percent of their dairy farms when using
this conventional standard.

“Getting bigger or get out really didn’t help a lot of the farmers. They got bigger
and they still went out of business.”

For a farm to get bigger, farmers confine hundreds or even thousands of dairy cows inside
large barns. That means farmers spend a lot of money and time bringing food to their
animals and hauling manure away.

Darrell Emmick says that model of agriculture started
in the 1940s when fuel was pretty cheap. But these days, it makes good economic sense
for farmers to go back to letting their milk cows out of the big barns to eat grass.

“Nothing can harvest a ton of feed any cheaper than the cow or the sheep or the
horse can by itself. Bringing food to animals is something I think we’re going to see a lot
less of, especially here and now with fuel prices going over four dollars a gallon.”

The Hill’s have made that switch on their farm. Ray Hill says his cows are healthier. He
believes their milk is better quality, too. And he’s excited about providing healthy
food for his community. Ray Hill says he wants their farm to be a place where people
come to buy quality food, and definately let him know if they have concerns.

“I want to have control over how I take care of my animals. I want to have control
over how I process or don’t process my milk. I want to have control over the price,
the quality. If there’s a quality issue, it’s up to me to take care of it, not say ‘let me
call so and so.’ I don’t think you can find anyone who’d that would tell you I’d
rather talk to a corporate person than the person who produced my food.”

But bucking against the system is not easy. There are days when no one comes to their
farm to buy their milk or yogurt. The Hills know they’re taking a risk. But they feel, at
least they’re not at the mercy of the industry, the banks and the whims of the market.

And for now, that’s worth it.

A Home for Unwanted Big Cats

When you think about lions or tigers, you probably think of African savannahs or Asian jungles… or the zoo. You probably don’t think about exotic cats living in the
house next door. But the number of big cats in homes has grown over the
years. The

When you think about lions or tigers, you probably think of African savannahs or Asian
jungles… or the zoo. You probably don’t think about exotic cats living in the house next
door. But the number of big cats in homes has grown over the years. The Great Lakes
Radio Consortium’s Christina Shockley reports on one woman who’s turned her home
into a sanctuary for big cats that need a place to live:


“Hi, handsome… hi, handsome. He loves to be scratched. He has absolutely no teeth.
He had every single one of his teeth taken out and he was declawed by a movie producer
in California. So he’d be safe to sit next to stars. Isn’t that sad? You can scratch and
cuddle him. He can’t hurt you in any way.”

Charlie is a big black panther.

He lives at “Valley of the Kings Sanctuary and Retreat” in the little town of Sharon,
Wisconsin.

About fifty big cats live here, along with bears, wolf hybrids, goats, foxes, chickens,
domestic cats, geese, ducks… and pretty much anything else that needs a home.

Before they got here, some of the animals—like Charlie— were altered so they’d be less
of a threat to people.

Others were mistreated in circuses… or zoos simply couldn’t take them in. Nearly all of
them would have been killed if they hadn’t found a home here…

Valley of the Kings is a private non-profit run by Jill Carnegie and her husband Jim Tomasi.

They live in a modest farmhouse on the sanctuary grounds. But even that has been partly
turned over to the animals.

At least five domestic cats roam the main floor, and Charlie the panther lives in a room
that’s been modified into a cage.

Jill Carnegie says animals have always been important in her life. She says they fill a
void. Carnegie says in her big family, she didn’t always get the attention she felt she
deserved.

“I never felt loved, but I always felt it from the animals. Their love was unconditional.
They didn’t lie to you. They didn’t betray you. They didn’t stab you in the back. They
didn’t hurt you. They were always, always 180 percent there for me. Always.”

Then, when she was about four years old… Carnegie says she came to believe she had a
gift.

“I remember going out into our side yard, and sending a message to the squirrels to come
and they would all come. And I would have bread and treats for them. And they would
eat, and we would just be really happy.”

Carnegie believes everyone has the ability to communicate with animals, but most people
choose to ignore it. Carnegie says it has helped her understand the big cats in her care.

Out on the sanctuary grounds, it’s clear that every big cat has a personality, like Kia.

Block: “She has a thing about women. She doesn’t like them (laughs).”


(Kia growls)


Chris Block has been volunteering at the sanctuary for about eight years. He says some
of these animals come from people who wanted to keep them as pets.

“But she’s this way to basically most people. She’s very antisocial. (cougar hisses) She
was owned by a truck driver, a cross country truck driver who wanted to get a baby
cougar and wanted to take her in the cab with him.”

Block says average people who buy exotic animals as pets don’t know what they’re
getting into. The cats can attack unprovoked, need special food, and get a lot bigger than
they are when they’re young.

Jill Carnegie, the sanctuary owner, has allowed some big cats to roam free in her house,
including a spotted Asian leopard.

Carnegie would sometimes even let the leopard sleep in her bed at night.

But at least one expert says this is going too far.

Richard Farinato is the director of captive wildlife programs at the Humane Society of the
United States.

“Every time you come into direct contact or you allow someone to come into direct
contact situation, with a big cat, you’re just playing the numbers game. It’s only a matter
of time before someone’s going to get hurt. Badly.”

Carnegie says she knows the cats are dangerous. But she says her bond with the big cats
and her experience working with them sets her apart from the rest.

“Again it goes back to common sense. I’ve been doing this for 32 years. We’ve never
ever had an injury, ever. And again, we’ve only had a handful of cats that have been safe
in the house, that I would trust anybody with.”

Authorities and neighbors have had some concerns about the sanctuary. Jill Carnegie
says she’s not even thinking about giving it up.

But, partly because of the concerns, Carnegie wants to find a new location for Valley of
the Kings.

She says then she’d have more room to expand and take in additional animals that need
homes and care.
