The Next Idea

You can see Michigan from space. It’s the mitten surrounded by all that blue with the bunny jumping over it.

In fact, almost half of the Great Lakes State is comprised of water. Michigan has more shoreline than any other state in the union, with the exception of Alaska, which is seven times larger.

The State of Michigan is weighing whether to open the door to commercial fish farming in the Great Lakes.

Millions of rainbow trout are raised for food by Canadians every year in Lake Huron and promoters of the business say Michigan should follow suit and could even become a world leader in aquaculture.

State officials are trying to figure out what the risks are and the idea is likely to face opposition from sport fishing groups and other conservationists.

The two reasons: 1) the process of moving water that far, and that high, wouldn't make economic sense; 2) Great Lakes water is locked down politically.

The ongoing drought in California has hit its fourth year.

They're known as "Areas of Concern" and Michigan had 14 of them at one time.

Now, we have 12 of these toxic places where pollution from the past is lingering.

This summer, work crews will tackle the next phase of cleanup in the Muskegon Lake area.

There’s plastic trash in every one of the Great Lakes.

That plastic includes junk people leave at the beach, microbeads from consumer products such as shower gel, face wash and toothpaste, and pellets from plastic manufacturing.

RJ Wolcott of the Grand Rapids Press spoke with the U.S. Fish and Wildlife Service's Vince Cavalieri about the return of the piping plover.

The endangered birds winter along the Gulf of Mexico, the southern Atlantic coast and in the Caribbean. Cavalieri says breeding pairs will soon arrive along the coasts of the northern Great Lakes.

With below freezing and single digit temperatures expected to continue through the week, ice cover on the Great Lakes is expected to continue to increase.

We hit a peak for the season yesterday with almost 86% ice cover for the Great Lakes -- that's well above where we were at this time last year (62%).

SAULT STE. MARIE, Mich. (AP) - As hard as it may be to imagine the nearly ice-covered Great Lakes as a Caribbean-like cruise ship destination, that's just what they'll be when summer comes to the world's largest fresh water system. 

Great Lakes Cruise Co. says it will begin offering itineraries between Montreal and Chicago in July on the M.S. Saint Laurent. The company's website describes the ship as a "4-star, intimate and charming ocean-going coastal vessel."

TRAVERSE CITY, Mich. (AP) - For the second consecutive winter, bitter weather threatens to turn the surface of the Great Lakes into a vast frozen plain.

The federal Great Lakes research laboratory in Ann Arbor reports Friday that nearly 81 percent of the five lakes' surface area is ice-covered. On Thursday, the ice cover exceeded 85 percent.

  The lab's George Leshkevich says the small drop-off probably happened because winds broke apart some ice, creating open spots.

A research team has discovered high levels of flame retardants in bald eagles in Michigan.

Polybrominated diphenyl ethers, or PBDEs, are in all kinds of consumer products.  They're in our couches, our TVs, our cars, our office chairs, the padding beneath our carpets, and the dust in our homes. But the chemicals don’t stay put. They leach out and build up in people and in wildlife.

"What we found was that some of the eagles, particularly in Michigan, had some of the highest exposures to flame retardant chemicals in the world," says Nil Basu, a professor at McGill University in Montreal.

There’s a new report card of sorts out on fish sold commercially from the Great Lakes.

It’s from Seafood Watch. That’s a program at Monterey Bay Aquarium in California.

A proposal to continue a wide-ranging Great Lakes cleanup program has been resurrected in Congress after falling short last month.

Rep. David Joyce, R-OH, introduced the bill Thursday. It would extend the soon-to-expire Great Lakes Restoration Initiative for another five years and authorize spending $300 million annually.

The oil spill disaster on the Kalamazoo River got many in Michigan wondering about the state of Michigan's oil and gas pipelines.

The Great Lakes go up and down. It's just a fact of life. 

Water levels in Lakes Superior, Michigan and Huron continue to be above their monthly averages for the first time in 16 years.

Lake Superior State University researchers have determined that Atlantic salmon are naturally reproducing in the St. Mary's River.

The prized game fish were originally native to Lake Ontario, but experienced a massive population decline by the late 1800's. Today, Atlantic salmon are stocked in the St. Mary's River and in other parts of the upper Great Lakes.

Though the Atlantic salmon population remained healthy when maintained by the St. Mary's fishery, the salmon population did not take root naturally, apparently due to a thiamine deficiency.

While conducting research for his senior undergraduate thesis on sturgeon, Stefan Tucker found what he suspected were Atlantic salmon fry in the St. Mary's River. His identification was later confirmed by University of Michigan taxonomist Gerald Smith. Tucker and a team of researchers concluded that the Atlantic salmon population is indeed naturally reproducing.

A press release from Lake Superior State University explains the implications of this finding:

The discovery is not only exciting for those at LSSU, the Michigan Dept. of Natural Resources, and others who have been involved with stocking Atlantic salmon in the upper Great Lakes for more than two decades, but also to anyone who follows the changing dynamics of the Great Lakes, especially in relation to lake trout and salmonids.

Though this discovery answers one question, it begs others.

Tucker concluded his thesis by stating that "the extent of natural reproduction and mechanisms influencing reproductive success are unclear and warrant further attention."

Michigan Radio's M I Curious project is a news experiment where we investigate questions submitted by the public about our state and its people.

As part of our M I Curious project, Shelly Scott asked Michigan Radio this question:

Have there ever been pirates on the Great Lakes?

“I thought: we’ve got such nice water bodies around here, why don’t we hear anything about fantastic things that happened on the Great Lakes?” she says.

Scott is an engineer at Ford and she’s also a leader of her daughter’s Girl Scout troop.  These 5th grade girls had some questions about freshwater pirates too:

“What do pirate ships look like? Was there any pirate treasure in the Great Lakes? How did they get away with stealing other people’s treasure?” asked Maria Kokko, Lilli Semel and Shannon Scott.

ALLEGAN, Mich. - Officials say genetic material of Asian carp has been found in a river in the Kalamazoo River in southwestern Michigan.

The state Department of Natural Resources and the U.S. Fish and Wildlife Service on Tuesday announced DNA from silver carp was detected in one of 200 samples taken in July the Kalamazoo River in Allegan County. The river flows into Lake Michigan.

Officials say the discovery marks the first time so-called environmental DNA for silver carp has been found in Michigan's Great Lakes waters outside of Maumee Bay in Lake Erie. In a statement, the agencies say there's "no evidence that a population of silver carp is established."

The silver carp is one of the Asian species threatening to invade the Great Lakes and compete with native fish for food.

Lakes Michigan and Huron have recovered after more than a decade of low water levels.

Government scientists say the lakes rose above their historic average this month.

Just two years ago, the water was at the lowest level ever recorded.

The quick recovery has stifled an effort to engineer a solution to the problem of low lake levels in Huron and Michigan.

But proponents say it would be shortsighted to forget about the issue.

Several Great Lakes mayors want stronger and faster action to keep Great Lakes drinking water safe.

A drinking water summit was held this week in Chicago, hosted by Chicago Mayor Rahm Emanuel and the Great Lakes and St. Lawrence Cities Initiative.

Nicola Crawhall, deputy director of the initiative, said the meeting was triggered by the August shutdown of Toledo Ohio's drinking water system. The water was contaminated by microcystin toxins.

"We felt that was a watershed moment, if you like," said Crawhall.

It wasn’t the real thing, but federal and state agencies joined with local groups to respond to a mock oil spill in northern Michigan today.

“That boom is to keep out any oil from coming on this side,” one of the coordinators told reporters, as he pointed at crews lowering pillow-like yellow floaters into the Indian River. 

The booms were deployed just downstream from where an oil pipeline has sprung a make-believe leak.  A short distance away, officials from a variety of agencies manned a full command center, organizing the response in the mock disaster drill. 

Sea lamprey

Beginning on Sept. 9, the U.S. Fish and Wildlife Service will start to apply lamprey-killing pesticides into the Muskegon River.

The sea lamprey is a blood-sucking eel-like invasive species living in the Great Lakes. The fish is native to the north Atlantic ocean and got into the Great Lakes around 1920. The numbers proliferated since then.

Michael Twohey is a fish biologist with the U.S. Fish & Wildlife Service. He says that the lamprey is devastating to the native fish population.

“They are very efficient fish-eating machines. Each one consumes about 40 pounds of lake trout in its lifetime," says Twohey.

That's why the sea lamprey killing is planned for the Muskegon River system, using a chemical called TFM. Twohey says it's remarkably benign to most other creatures. The chemical will kill the sea lamprey larvae and largely leave everything else intact.

"We just can't have a sustainable fishery without sea lamprey control programs," says Twohey.

This Saturday, 35 baby sturgeon will be released into the Kalamazoo River at a sturgeon release party. It’ll be in New Richmond and it’s open to the public.

Lake sturgeon are ancient fish. They’re Michigan’s oldest and biggest fish species and can live to be more than 100 years old. Many populations of lake sturgeon in the Great Lakes were wiped out decades ago, but people have been working to bring them back.

Michigan took a big step forward this summer in the business of fish farming. The state issued a permit to expand the Grayling Fish Hatchery more than tenfold.The hatchery raises trout for restaurants and grocery stores.

The expansion comes as interest in fish farming is growing nationwide and there is now talk of going offshore into the open waters of the Great Lakes.

The Grayling Fish Hatchery could soon be the largest aquaculture operation in Michigan by far.

Dan Vogler is one of the owners of Harrietta Hills Trout Farm based near Cadillac. He hopes the expansion is a sign of a growing fish-producing industry in Michigan.
