The bass are getting fat.

Lake Michigan was recently recognized as one of the best places in America to fish for bass. The booming fishery is one sign of what might be a major shift of the lake’s food web.

But that change is being driven by an increase in goby, an invasive species. And it could spell trouble for salmon— the most popular sport fish in Lake Michigan.

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.

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.

The people who manage salmon in Lake Michigan will have to decide soon how many fish to put into the lake.  The salmon fishery is a manmade industry in the Great Lakes.  It’s produced by planting millions and millions of fish in the lakes.  But keeping the salmon population in balance with the food supply is a challenge these days.  And some scientists are raising new questions about the salmon’s demise in Lake Huron and whether that can be stopped in Lake Michigan.  

Salmon were brought in from the Pacific Ocean.

US Supreme Court

Five Great Lakes states are waiting to find out if the U.S. Supreme Court will hear their case calling for more decisive measures to keep Asian carp from reaching the Great Lakes.

Michigan, Wisconsin, Ohio, Minnesota, and Pennsylvania filed the request this week.

The states want the U.S. Army Corps of Engineers to quickly wrap up its study of how to keep Asian carp from escaping the Mississippi River system through Chicago-area shipping canals. The corps is one of the main agencies responsible for the locks.

John Sellek is the spokesman for Michigan Attorney General Bill Schuette.

“What we really want is to have the Army Corps of Engineers speed up their study,” said Sellek.

“They are taking up to five years or longer to look at this and every minute that goes by could be another fish that’s getting through those canals in Chicago, so what we’re requesting is they speed that up to 18 months at the longest.”

The Great Lakes states also want the high court to order the corps to string nets across smaller waterways that could be escape points for the carp.

At the same time, Michigan and 17 states along the Great Lakes or the Mississippi want a total physical separation of the water systems.
