Fish populations native to Michigan such as lake sturgeon, walleye, and lake whitefish have been declining in recent years.

As a result, the Great Lakes Restoration Initiative has built spawning reefs in rivers around Michigan, including the St. Clair River.

A spawning reef is a crevice-filled rock bed designed to mimic the natural limestone reefs that previously existed.

Pregnant women need to eat more fish, say FDA and EPA

Credit rick/ Flickr

The government wants pregnant women to eat more fish. Yesterday the FDA and EPA issued new draft advice that urges pregnant and breastfeeding women to eat at least eight to twelve ounces of fish a week.

The update comes 10 years after the last recommendation, which didn't specify a minimum.

The FDA is worried that fears over mercury levels in seafood have kept many pregnant women from getting enough of the nutritional value needed for their babies.

Why do some trout that dine on small invasive fish die? Researchers gaining clues

You’ve probably heard about the big bad invasive silver or bighead carp, also known as Asian carp.

But there’s another invasive fish that’s roughly a third the size of the carp that’s already done a lot of damage to Great Lakes fisheries. Alewives have been a particular menace in Lakes Michigan and Huron. The invasive fish cause all kinds of problems for native lake trout.

Alewives scarf down lake trout eggs and very young fish. But even once lake trout grow big enough to turn the tables and eat the alewives, the invasive fish still cause problems.

Whitefish shortage causing Passover meal problems

TRAVERSE CITY – Many fish markets in the Great Lakes region are running short of whitefish, and it's coming at a bad time: the Passover holiday.

Whitefish is a key ingredient in gefilte fish, a traditional Jewish dish that originates in eastern Europe. Recipes vary, but it often consists of ground fish, vegetables such as onion and carrots, and bread crumbs formed into loaves or balls.

The shortfall results partly from the bitterly cold winter that caused vast sections of the Great Lakes to freeze over. The ice cover kept some commercial fishing crews stuck in port. A drop in the whitefish population is also to blame.

Kevin Dean of Superior Fish Co. near Detroit says his latest shipment amounted to just 75 pounds, although he requested 500 pounds.

So you know the saying, right? Stuff flows downhill? Myron Erickson knows a lot about that "stuff."

He heads up the sewage treatment plant that sits along the Grand River in Wyoming, Michigan (right next to Grand Rapids).

The screening room is where they take out the "grit." Erickson calls them "knick knacks."

"It's a small particle like sand, and also all things that come to us in sewage, like peas, and corn, and peanuts," says Erickson.

Go lake trout! Native fish overcome seemingly ‘insurmountable’ challenges in Lake Huron

A fish that was almost wiped out in the Great Lakes is making a comeback in Lake Huron.

Lake trout are suddenly doing what biologists have been trying to get them to do for more than 40 years: They’re making babies.

Lake trout used to be a mainstay of Great Lakes commercial fishing in the first half of the twentieth century. The Lakes would produce 15 million pounds of the fish every year.

Then the sea lamprey came in and sucked the life out of the lake trout populations.

Women making healthier decisions at seafood counter

Women are asking which fish contain more of the toxin mercury and choosing those fish. Mercury levels in women's blood have decreased 34% during the last decade.
Credit Lester Graham / Michigan Radio

Over the last decade, women have switched to making much healthier choices at the seafood counter.

First, let's make it clear: fish is healthful food.

But, fish can contain traces of mercury, some fish more than others. And to make sure you don’t consume too much of that toxin, you need to know which fish have heavier loads of mercury.

Why?

Because mercury is a toxic contaminant that can cause neurological damage. For women who could have children or who are pregnant, too much mercury could mean developmental problems for their babies.

'Lake Erie has 2% of the water in the Great Lakes, but 50% of the fish'

The 2011 algae bloom on Lake Erie. Significant blooms returned to Lake Erie around 2000-01. Researchers are looking into how these blooms affect fish.

The stat comes from Jeff Reutter, Director of Ohio State University's Stone Laboratory. He says the converse is true for Lake Superior. It holds 50% of the water, but just 2% of the fish.

It's a rough estimate, he says, but it gives you a good understanding of how each of the five Great Lakes have unique characteristics, which present unique challenges in managing these lakes.

As part of our series on how climate change is affecting the Great Lakes, Reutter spoke to us about how Lake Erie is especially vulnerable to temperature variations. It is the southernmost, and the shallowest of the five Great Lakes.

He also spoke about how, unlike the other four Great Lakes, Lake Erie is surrounded by agriculture and a more urbanized landscape.

You can listen to him speak about his "50 and 2 Rule" here:

Lake Erie has seen a resurgence in algal blooms over the last ten years. It was once a big problem in the 60s and 70s, and it has returned as a problem again.

You can listen to today's Environment Report above.

A research expedition recently set sail from Chicago to search for a Great Lakes garbage patch.

So-called "garbage patches" or islands are actually collections of tiny plastic particles that are choking up regions of the world’s oceans. The expedition has been testing the waters of Lakes Huron and Michigan for a similar phenomenon.

I met up with expedition organizer Asta Mail at a marina in downtown Chicago. It’s a hot day, and a street vendor immediately offers us bottled water.

Mail points down at a plastic bottle in Lake Michigan. It’s pretty easy plastic hunting.

The Great Lakes need help to stay stocked with fish

An interview with Gary Whelan of the State Department of Natural Resources.

Here's something to think about the next time you pick up a fishing pole and cast into one of the Great Lakes.

That fish you catch might have gotten there not courtesy of Mother Nature, but rather with some help from the Michigan Department of Natural Resources.

This year alone, the MDNR will stock about 19 million fish into the Great Lakes.

Gary Whelan is with the State Department of Natural Resources and he joined us today from Lansing.

Stateside for Monday, July 15th, 2013

Democrats in the state House have introduced a package of bills that would add more state regulations to the process of hydraulic fracturing, or ‘fracking.’ We spoke to a co-sponsor of the legislation on today's show.

And, as the use of meth makes headlines across the state, we talked to one woman about her recovery and what she's doing for other addicts.

And, it’s going to be a hot week for Michiganders. We took a look at what health concerns are related to the increased temperatures.

Also, we spoke with Gary Whelan of the State Department of Natural Resources about what is being done to keep the Great Lakes stocked with fish.

First on the show, the debate over expanding Medicaid in Michigan continues.

Governor Snyder is still pushing for the state Senate to vote on the legislation. It would expand Medicaid to hundreds of thousands of low-income adults in the state. The state House has already approved it.

Over the weekend, Mark Schauer waded into the debate.

Schauer – a Democrat – is running for Governor in 2014. He said on Saturday that he does not understand why Governor Snyder is not calling the Legislature into a special session.

Rick Pluta and Zoe Clark, Michigan Radio’s “It’s Just Politics” team, joined us today to answer Mark Shauer’s question.

Study shows Asian carp eggs could survive in tougher conditions than previously thought

Wildlife managers could have a harder time controlling spawning Asian carp, if they escape into the Lake Michigan from Chicago-area shipping canals. That's according to a report released by the U.S. Geological Survey.

Elizabeth Murphy is a hydrologist with the USGS. She co-authored the study.

Murphy says new data shows fertilized Asian carp eggs can incubate in waterways that are only 16 miles long. That’s a lot less than the 62 miles scientists thought the drifting eggs needed.

Prehistoric fish species with 'personalities' get help from humans to survive

You can listen to today's Environment Report above.

It’s near the end of spawning season for Michigan’s oldest and biggest fish species, the lake sturgeon. Overfishing and hydraulic dams built to power industry have wiped out many lake sturgeon populations in the Great Lakes.

A group of people and government agencies are trying to increase the odds the kind of sturgeon specific to the Kalamazoo River will survive.

Sturgeon have been around since the age of dinosaurs. So they’re a lot different from other fish in the Great Lakes. They don’t have a normal skeleton. Instead, they’ve got these bony plates on the outside of their bodies, called scutes. They have no fish scales.

“They’re kind of rubbery on the outside and they are extremely docile, unlike the fish with the flopping and all that,” said Ron Clark. He’s with the Kalamazoo River Sturgeon Restoration Project out of New Richmond.

“They let you move them; they let you hold them,” Clark said.

For the first time in nearly a half century, people will be encouraged to fish along a portion of the Red Cedar River as it winds its way through the Michigan State University campus in East Lansing.

At a ceremony Monday near the campus’s western edge, MSU dignitaries, including Sparty, took turns dumping buckets of Steelhead trout into the meandering Red Cedar River.

Organizers want anglers to start casting their lines into the Red Ceder in hopes of reeling in the sportfish.

Stateside: Fish farming in Detroit

Noah Link is the co-owner of Food Field. It's a small farm in Detroit's Boston-Edison neighborhood. Link calls the converted shipping container his "post-industrial" farm house.
Mercedes Mejia

The Detroit Planning Commission recently approved a new Urban Agriculture Ordinance. The action takes the city a step closer to officially recognizing the dozens of urban farms and gardens scattered across the city.

The ordinance also defines the kinds of projects that would be allowed, such as farm stands, orchards or greenhouses. Stateside’s Mercedes Mejia reports some residents are experimenting with aquaponic systems. It’s a method of growing crops and fish at the same time.

Noah Link: Over here is our chicken coop. We have about 42 chickens and 4 ducks so far. You can hear the ducks – they’ve awfully loud and hungry probably.

Noah Link is the co-owner of Food Field. He lives and works in the Boston-Edison neighborhood in Detroit. I met up with him on his farm called Food Field. It’s on the site of a former elementary school - imagine a small farm tucked away in the city.

 "So if you go a few blocks one way there are huge historical mansions, and you go a few blocks the other way and it’s all run down old shops, and total poverty, and we’re right in between," he says.

Link and his business partner worked on several farms across the country. They knew it wouldn’t be easy to own a farm, but they’re doing the hard work. On the land are different kinds of crops, chickens, a few beehives, and a young orchard of fruit and nuts trees. There’s also a hoop house to grow vegetables year-round.

"And we’ve just built an aquaponic system to be able to raise fish in there, which I’ll show you."

An aquaponic system is a combination of hydroponics and aquaculture - growing plants in water and fish farming.

"And it takes the best of both of those in a self-sustaining system so then rather than having to worry about toxic fish waste to get rid of or keeping it sterile hydroponic environment for your plants, the plants grow out of the waste water from the fish that just get circulated with the pump and they clean out the water to keep it safe for all the fish in the tank," Link says.

States to cut way back on Lake Michigan Chinook stocking

Lake Michigan's Chinook salmon are doing so well that Michigan and other states and tribes in the region have decided to sharply reduce stocking rates of the popular game fish.

The Michigan Department of Natural Resources announced Monday that it will cut its annual Chinook stocking in the lake by two-thirds, from 1.67 million to 560,000. The change begins in spring 2013.

The MDNR says because the fish are reproducing naturally in significant numbers in Michigan, the state "will shoulder the majority of the stocking reduction."

Michigan will reduce stocking by 1.13 million spring fingerlings, or 67 percent of the 1.69 million recently stocked by the state. Wisconsin will reduce by 440,000; Indiana will reduce by 25,000; and Illinois will reduce by 20,000.

The state agencies are following recommendations of the Lake Michigan Committee.

The Lake Michigan Committee is comprised of fisheries managers from Michigan, Indiana, Illinois, Wisconsin and five Michigan tribes that are party to the 2000 Consent Decree.

In total stocking will be cut in half, going from 3.3 million to 1.7 million annually.

Naturalists say overstocking of predator fish threatens the population of other lake species and upsets the ecological balance. Half the Chinook in the lake now are the result of natural reproduction.

The MDNR says the decision to reduce stocking is part of an "adaptive management strategy." They say they will monitor indicators in the lake, such as Chinook salmon growth, and adjust to the conditions in Lake Michigan.

If conditions improve or get worse, stocking will be increased or decreased accordingly, and more quickly.

"This will give the DNR more flexibility to adaptively manage the lake," said Jay Wesley, Southern Lake Michigan Unit manager. "Traditionally, we have made changes in stocking and waited five years to evaluate it, and another two years to implement changes. Now we have the ability, through a defined and accepted process, to make changes as they are needed."

2 sturgeon found washed ashore off Lake Huron

Lake Sturgeon
MI DNR website

The Times Herald in Port Huron reports that a Lakeport resident found a 3-foot-long sturgeon this week on a beach.

 The newspaper reports that a 4-foot-long sturgeon also washed ashore in Fort Gratiot, northeast of Detroit.

Michigan Natural Resources fisheries biologist Mike Thomas says it's not unheard of for small numbers of the fish to wash up in one week, but he is "kind of watching what's going on."
