fish

The State of Michigan is finding industrial chemicals known as PFAS in the tissue of fish. So it's been issuing “Don’t Eat the Fish” advisories along lakes, rivers and streams. But there are concerns about whether state officials are doing as much as they should. 

Before we get too far into the story, we have to start with a little science.

The reason PFAS chemical contamination in fish is such a concern is because of something called bioaccumulation.

Antidepressants that people take are building up in the brains of fish like walleye, bass, and perch. Researchers studied fish from the Niagara River, which connects lakes Erie and Ontario.

There are two environmental stories making news today.

First, fish in Lake St. Clair have a virus (VHSV) that is causing thousands of them to wash up dead on the shore. Luckily, eating a fish with VHSV is not expected to cause any adverse health problems for humans, but with that many fish dying in the lake, this could cause a problem for the ecosystem. 

Second, Nestle has put in a bid to pump more Michigan groundwater to produce Ice Mountain bottled water for consumers, but they were denied. However, that's not the end of the story.

It’s the busy time of year for commercial fishing on the Great Lakes. But the price of whitefish is about half what it was three years ago, because of problems with international trade.

Michigan lawmakers are talking about banning tiny balls of plastic in products sold in Michigan.

A lot of us use products with microbeads in them. They’re tiny, perfectly round plastic beads that companies add to face and body scrubs and toothpaste.

We wash them down the drain, but they’re so small that wastewater treatment plants can’t filter them out.

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.

Monahan’s Seafood Market in Ann Arbor carries soft-shell crabs from Maryland, Alaskan salmon, and Florida red snapper.

But at the moment, they’re fresh out of Great Lakes whitefish.

Bernie Fritzsch manages the fish market.

“We’re hoping to see it today, but we haven’t seen it for the last week,” he says.

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.

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.

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.

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.

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.

Listen to the full interview above.

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.

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.

That’s a big change.

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.
