Earlier this month, officials in Michigan announced that genetic material from silver carp, a species of Asian carp, had been discovered in the Kalamazoo River around 20 miles upstream from where the river flows into Lake Michigan. It was the first time a positive sample of eDNA had been found that close to the lake.
The results drew national attention and had many concerned that it wouldn’t be long until the infamous invader entered the Great Lakes. Further testing, though, reveals that there is no evidence of Asian carp in the river, Lake Michigan, or any of the other Great Lakes.
“We are pleased these samples were negative, but that doesn’t mean our efforts to keep Michigan’s waters are over,” DNR Fisheries Division Chief Jim Dexter said in a statement.
Asian carp were imported in the South several decades ago, where they served a utilitarian role on fish farms. But with no natural predator, the prodigious eaters and reproducers quickly escaped and began steadily invading the Mississippi River system.
Having arrived on the doorsteps of the Great Lakes, officials in Michigan, Ohio, Wisconsin, Pennsylvania, New York and others are working diligently to organize a strategy for keeping the invasive swimmers out.
Environmentalists, ecologists and others say the carp could decimate food chains and habitats in the Great Lakes, diminishing biodiversity there and threatening a multibillion-dollar fishing industry.
The threat comes from the invaders ravenous diet and ability to out-compete native fish for food. In the Illinois River, they have already fundamentally changed the food web.
From the Spring 2013 Helm:
Asian carp do more than compete for food. They actually force native fish to change their diets, feeding on species lower on the food chain than they natural would. In a healthy food web, filter-feeders, like gizzard shad and paddlefish, eat a variety of plankton species, ensuring that there is enough food to go around. But Asian car have all but wiped out the larger zooplankton in the Illinois River, pushing fish that have historically relied on that food source to turn to smaller zooplankton and phytoplankton for a meal. As the number of Asian carp in an area grows, more and more native fish are left competing for a smaller supply of plankton.

Scientists from Central Michigan University’s Institute for Great Lakes Research (IGLR) are expanding their basin-wide Great Lakes coastal wetlands monitoring program with help from grant funding from the U.S. Fish and Wildlife Service and the Wisconsin and Illinois-Indiana Sea Grant programs. The program is one part of a collaborative project that brings together researchers from IGLR, Notre Dame, and the University of Wisconsin-Green Bay. The results will help natural resource managers better target protection and restoration efforts.
From the Midland Daily News:
They also will be able to help assess the importance of coastal wetlands as they relate to the food web of the Great Lakes ecosystem by studying otoliths, or fish ear bones, to determine where fish are obtaining energy for growth.
Otoliths grow daily, similar to rings found in the trunk of a tree. With the use of a precise laser beam, IGLR researchers can sample the chemical composition of targeted areas of the otoliths and relate this “chemical fingerprint” to specific coastal wetlands, even when fish are caught in the open water of the Great Lakes, far from any wetlands.
It is hoped that this research will result in a long-term, sustainable monitoring program aimed at restoring and protecting Great Lakes coastal wetlands, which provide a critical habitat for many species of birds, mammals, reptiles and amphibians, and an essential spawning and nursery habitat for many fish species of ecological and economical importance to Michigan’s $7.5 billion commercial and sports fishing industry.
The research project is one of three awarded a combined total of $380,000 from IISG earlier this year. Additional projects seek to uncover the connections between sediment removal projects and a community’s ability to weather environmental hazards and identify why people adopt stormwater management practices.
And IISG continues to fund strong research projects like these. In fact, last month we announced a new funding opportunity for research addressing key economic planning questions facing the Great Lakes region. Researchers may request up to $96,000 for 18 months. Proposals are due by 5 pm CST on Nov. 17, 2014. Read the full RFP for information on project and application requirements.

Jumpin’ Jack, the silver carp sensation known for his glam look and high-flying stage tricks, will join Lady Quagga on tour of schools and public events starting this month.
Despite differences in their history and style, the two have been dubbed a ‘captivating duo’ by many critics. Several experts have also commended the “spokes-mussel” and “flying fish” for dedicating their tour to spreading the word about the risks of
aquatic invasive species and how people can help prevent their spread.
Jumpin’ Jack, along with his cousin bighead carp, initially came to the U.S. in the 1970s to help control algae growth in aquaculture and municipal wastewater treatment plants. They soon moved to nearby lakes and rivers and are now a common sight on major rivers like the Illinois and Mississippi. Together, these Asian carp have knocked back plankton populations, crowded out native species, and seriously injured boaters.
In addition to traveling with Lady Quagga, Jumpin’ Jack is also booking independent appearances. Contact his manager,
Terri Hallesy, for more information.

For land use planners, balancing community growth and environmental health is always a challenge. But after months of pilot testing, IISG is putting the final touches on a new web-based tool that will help them do just that.
The Tipping Points and Indicators tool uses the latest watershed research and cutting-edge technology to show planners where aquatic ecosystems in their area are in danger of crossing a “tipping point,” triggering rapid and sometimes irreversible shifts in how they function. With help from a Sea Grant facilitator, planners can use the tool’s interactive maps, simulators, and recommended response strategies to develop watershed-specific plans that prevent ecosystems from being degraded beyond repair.
Specialists from Ohio, New York, Minnesota, Wisconsin, Michigan and Illinois-Indiana Sea Grant programs have spent the last few months testing the tool in broad range of communities and divers audiences. Planning groups from the industrialized southern Lake Michigan to the more preserved northern Wisconsin and Minnesota can now use the decision support system to kick off the watershed planning process. In Indiana, Ohio, and New York, facilitators have also introduced planning consultants and state employees to tool modules so they can take the process back to their own communities.
Experiences so far have been positive, with many users expressing excitement about the role Tipping Points and Indicators could play in improving watershed planning. Community members, local officials, and consultants were particularly interested in the tools’ recommended policies, ordinances, and outreach efforts tailored to local needs. In fact, a watershed advocacy group from the Duluth area mentioned they could have spent a whole day on that module alone.
To further enhance the tool, users also recommended making maps and planning strategies more watershed-specific. Many of these refinements are being made now. Others, including the addition of the new land cover data and models that predict future tipping points, are expected in the coming months.
And as the project grows, so does the lead team. Last month, IISG brought Purdue software developer Brandon Beatty onboard to help boost the usability of Tipping Points and Indicators and ensure it continues to rely on the latest research and technology.
The tipping points tool is part of a four-year project funded by NOAA and EPA and coordinated by Illinois-Indiana Sea Grant. Partners include Purdue University, University of Michigan, Michigan State University, University of Minnesota Duluth, University of Windsor, Great Lakes Environmental Research Laboratory, the Cooperative Institute for Limnology and Ecosystem Research, the Great Lakes Restoration Initiative, and the Sea Grant Great Lakes Network.

It’s day four of the Shipboard and Shoreline Science Workshop, and teachers from across the Great Lakes region are hard at work conducting field experiments alongside researchers aboard the EPA R/V Lake Guardian. The group was in Lake Erie’s Presque Isle Bay yesterday collecting water samples and hunting for invasive species. Their work, along with some of the researchers and participants, was featured on WICU 12 Erie.
“I’m going to bring this back to my classroom,” Chad Solomon, a teacher at Chicago’s Whitney M. Young Magnet High School told WICU. “We live in Chicago, but very rarely do kids actually get to the lake. I am going to be bringing this experience back to them.”
Joining the teachers at this shoreline stop and throughout the research cruise is IISG’s Kristin TePas. Kristin coordinates the annual teacher workshop, held each year on a different lake, for the Center for Great Lakes Literacy and the EPA Great Lakes National Program Office.
Sea Grant-funded researchers Sam Mason and Steve Mauro were also on board sampling for emerging pollutants like plastic and pharmaceuticals. You can learn more about Mason’s research in Lake Erie and across the Great Lakes in the latest issue of UpClose. And watch for the next edition later this month to hear from Mauro directly about his work on the Lake Guardian.

While Asian carp, the invasive fish making their way towards the Great Lakes, are a popular food in several countries, they haven’t completely taken hold here. But that may change if proprietors like Dirk Fucik in Chicago have their way.
“Highly invasive Asian carp are advancing on the Great Lakes, so fire up your grill. Asian carp are eaten and appreciated globally, but the fish have never been popular in America because they’re bony and are thought to be bottom-feeders (actually, you can tell your pesca-prejudiced pals, Asian carp are plankton-feeders.) Nevertheless, Asian carp burgers at Dirk’s Fish & Gourmet Shop have been well-received.
’90 percent of the people who try it like it,’ Dirk Fucik says. At Taste of Chicago one year, Fucik gave out 800 carp burgers in two hours.
Fucik fillets the carp, then grinds the remaining fish. ‘Once you’ve done that, it’s like ground anything,’ Fucik says. He’s used Asian carp in the meatballs in Italian wedding soup, and he’s received a lot of compliments for his Asian carp gefilte fish. Fucik recommends preparing his burgers with some cambozola cheese in the middle, or using Dirk’s Thai or ‘Terry-aki’ marinades. The burgers cost $6 per pound, compared to $18 a pound for salmon burgers.”

It’s Fourth of July! Let’s head for the beach! You’ve packed up towels and snacks and sunscreen for a day in the sun and surf. Now give some thought to water safety too.
Since 2010, 357 people have drowned in the Great Lakes, according to the Great Lakes Surf Rescue Project (GLSRP). To date, GLSRP has tracked 27 deaths this year, which is up from this time last year. This may be due to the water’s cold temperatures after a tough winter. Colder water uses up your energy faster than warmer water.
GLSRP’s Dave Benjamin and Bob Pratt teach water safety classes on beaches, in schools, and at other venues. On June 30, they brought their message to Ogden Dunes in Indiana, advocating for safer swimmers, safer waters, and safer responses.
Safer swimmers means learning how to swim, but if that’s not the case, putting on life jackets, or other flotation aids, especially for young children. It also means keeping a close eye on children in the water.
But children are not the only ones at risk. Young men make up 4 in 5 deaths from drowning. They tend to take more risks, or can be over confident about their swimming skills.
Safer waters mean swimming where there are lifeguards and away from structures that can cause dangerous currents around them.
Part of a safer response is knowing what it looks like when someone is in trouble in the water. “Hollywood portrays drowning as this very dramatic thing with the victim waving their arms and shouting for help, but when someone is drowning you will simply see their head tilted back in the water and a look of distress on their face,” said Benjamin.
The safe swimming experts recommend looking around the beach before trouble happens to spot items that can be used for floatation. For example, if you haven’t brought a cooler yourself, you will probably see others on the beach that can be used in an emergency.
If you find yourself in troubled waters, such as a rip current, the most important thing to do is not panic. Pratt recommends that you remember to flip, float, and follow. “Flip over on your back, float to conserve energy, and follow the current so that when you know where it is headed, you can swim out of it.”

The efforts of an Illinois teacher to bring Great Lakes science into the classroom were brought center stage in the latest edition of Teacher Features, a monthly online series that showcases outstanding educators in the Great Lakes region.
Eileen DeJong, a teacher at Suak Village’s Rickover Junior High, is one of 14 teachers from Illinois and Indiana who learned about local aquatic ecosystems and ideas for hands-on stewardship activities at last summer’s B-WET workshop. In this edition, she talks about the importance of raising awareness of Great Lakes issues, past classroom projects, and her plans for the future.
From Teacher Features:
1. Why do you think it’s important to infuse Great Lakes topics in education?
I think it’s important that I incorporate information about our Great Lakes into my teaching because our school is impacted in many ways by one of the Great Lakes (Lake Michigan). Students respond to information that makes sense to them and that affects their life, and because Lake Michigan is so close to us (within 45 minutes); it’s a great way to get students involved in current environmental issues. We can study about aquatic invasive species affecting Lake Michigan and then GO TO Indiana Dunes, for example, and conduct experiments there. Or … even closer to home, we can study about invasive species harming our local forests, and then GO TO nearby forest preserves and volunteer. It’s all about making connections. Studying the Great Lakes topics make science REAL for my students and helps foster natural curiosity about their surroundings. It is also important because the problem of invasive species is a current environmental issue, and it’s happening in our own backyard. It encourages my students to become knowledgeable about factors affecting their living environment and to become activists for change.

Teacher Features is part of the Center for Great Lakes Literacy’s (CGLL) ongoing efforts to boost awareness of issues facing the Great Lakes watershed and inspire greater community stewardship. The group is led by Sea Grant educators throughout the region and conducts numerous teacher trainings each year, including the annual Shipboard Science workshop.

It’s beach season once again in southern Lake Michigan, and the rip current warnings have already begun.
The National Weather Service (NWS) has issued at least one advisory since Illinois and Indiana beaches opened last month asking beach-goers to think twice before taking a dip in the lake. And for good reason. Rip currents and other dangerous currents are the biggest threat to Great Lakes swimmers. Roughly 140 people have drowned in the lakes over the last 12 years due at least in part to dangerous currents. And most of those incidents happened in Lake Michigan.
Illinois-Indiana Sea Grant hopes to bring these numbers down with a new outreach effort that will raise awareness about dangerous currents in the Great Lakes. The “Implementing Dangerous Currents Best Practices” project was recently awarded funding from the NOAA Coastal Storms Program.
A collaborative effort Sea Grant programs in Michigan and Wisconsin, the project will include print and online resources—including educational videos—that introduce the science behind rip currents, provide tips for avoiding them, and explain what to do if you or others are caught in one. Many of these resources will be available in both English and Spanish.
Watch for further information on these outreach efforts and rip currents in the coming months. In the meantime, you can find tips for staying safe at the beach this summer at dangerouscurrents.org.
“Implementing Dangerous Currents Best Practices” continues years of efforts by Great Lakes Sea Grant programs, NOAA, and NWS to reduce dangerous currents drownings across the region. To learn more about these efforts, visit Rip Current Safety.
