The extensive ice cover could delay fish migrations in the Great Lakes

The prolonged winter and the ice cover on the Great Lakes could lead to some lasting effects on wildlife.

For one thing, scientists expect that a lot of the fish that people like to catch will be showing up late to the places they usually spawn.

Solomon David is a research scientist at Shedd Aquarium in Chicago.

David basically chases fish around for a living.

Ohio explores return of sturgeon to Lake Erie

PORT CLINTON, Ohio (AP) - Ohio's wildlife agency is looking at bringing a prehistoric fish back to Lake Erie. The Ohio Department of Natural Resources is looking into whether it can reintroduce breeding populations of sturgeon to the lake. 

Sturgeon were once plentiful but thought to be all but gone from Lake Erie less than two decades ago.

A good summer for raising baby sturgeon in northern Michigan

It’s been a fantastic summer for one lake sturgeon hatchery in Michigan.

Many lake sturgeon populations in the Great Lakes were wiped out decades ago. Demand for their eggs for caviar led to overfishing. Plus, dams built to power industry blocked sturgeon spawning grounds upstream.

Last spring, we told you about new efforts to restore a sub-species of sturgeon in the Kalamazoo River. This is the time of year when these little hatchery-raised fish are supposed to get released.

Unfortunately, things didn’t go very well for the new hatchery in the Kalamazoo River. Of the couple thousand eggs they had, only 52 survived. They were released into the river earlier this summer without much fanfare.

But I found another hatchery for lake sturgeon in Michigan that had an awesome year. This one is way up near Onaway, at the tip of the Lower Peninsula. They had a big release party last week.

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

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.

Sturgeon season to open on Michigan lake

Lake sturgeon are amazing fish. They can weigh several hundred pounds and they can live to be 100 years old.

Sturgeon used to be abundant throughout the Great Lakes region. But they were overfished, and construction of dams on rivers where they spawn hurt their reproduction. They’re now a state threatened species.

Tim Cwalinski is a fisheries biologist with the Michigan Department of Natural Resources. He says these days, sturgeon are carefully managed.  There are a few fishing seasons for sturgeon in different parts of the state.

The season for sturgeon in Black Lake in Cheboygan County opens February 2nd. Tim Cwalinski says there are about 1,200 adult sturgeon in the lake.  The quota this year is just six fish total for all the fishermen combined.

Swimming Upstream: Fending off sturgeon poachers (part 4)

This week, we're focusing on fish for our series Swimming Upstream. And today, Dustin Dwyer has a story about one of the most fascinating fish in the Great Lakes. Sturgeon have been around for more than 100 million years.  Each fish can live more than a hundred years, weigh more than a hundred pounds and stretch eight or nine feet long. But sturgeon have also been the target of overfishing and poaching. Dustin caught up with one group in northern Michigan that's trying to save them.  Here's his story:

So about a month or two ago, I was sitting along the bank of the Black River, way up near Onaway. And I was next to Jesse Hide, who has lived in this area all his life, and watched sturgeon all his life. We were keeping an eye out for sturgeon heading up the river to spawn.

“There's one coming up right there ... he's coming back down now.”

The long, spear-like fish occasionally poke their heads out of the water, like a submarine coming to the surface.
