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 blooms of cyanobacteria (sometimes referred to as blue-green algae) over the last ten years. It was once a big problem in the 60s and 70s, and it has returned as a problem again.

One day in the mid-1990s, a woman I knew went off to get her hair done. When the time came to pay, however, she offered the bewildered hairdresser less than a dollar. Suddenly, she wanted to pay everyone 1940’s prices. This didn’t go over very well. But it was soon clear that she was suffering from a fast-moving form of dementia. She wasn’t to blame for her idea that she ought to pay far less than things were worth.

However, those in charge of our state are to blame if they aren’t willing to charge what things are worth, or pay for things which are good long-term investments. We have two examples of that right now.

One is the governor’s call to raise hunting and fishing licenses. This set off howls of protests from sporting groups. But Michigan has been undercharging for these licenses for years, and the state -- and specifically the Department of Natural Resources -- have been losing out on millions badly needed for conservation. Much of that money from the pockets of out-of-state hunters.

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."

Michigan’s tourism and fishing industries will discuss how to form a united front against Asian carp during a conference Tuesday in Lansing.  John Goss, the Obama Administration’s "carp czar," will be the keynote speaker at the  conference.  

Asian carp present a threat to the Great Lakes’ multi-billion dollar sport fishing and tourism industries, according to Steve Yencich, president of the Tourism Industries Coalition of Michigan.  The coalition is organizing the carp summit.

For twenty years now the federal government has been trying to restore wild lake trout in Lake Michigan. Lake trout are native to the Great Lakes and were once the big game fish in all the lakes. The species is doing well in Lakes Superior and Huron these days. But recovery efforts in Lake Michigan have been almost a total failure.

Lake trout don’t have a big fan club. Anglers would prefer to land a salmon. And retail markets for lake trout are weak.
