Continuing research on Lake Michigan and throughout the Great Lakes is turning up important information on the presence and concentration of microplastics – particles too small to be filtered by water treatment plants, but which can have negative effects on the environment.
From the StarTribune:
“Fresh off the research boat, Lorena Rios-Mendoza, assistant professor of chemistry at the University of Wisconsin-Superior, presented her preliminary findings to reporters Thursday.
She said Lake Erie seems to hold the highest concentrations of plastics, probably because the particles float downstream from the upper lakes, according to the Duluth News Tribune (http://bit.ly/1cnm6BS ).
The plastic has also been found in Lake Superior sediment, meaning it’s not just floating on the surface, Rios-Mendoza said.
‘It was very shallow where they were found, but they were in the sediment,’ Rios-Mendoza said.
The researchers dragged fine-mesh nets across the surface of lakes. Some of the plastic can be seen only under a microscope.
So far, Rios-Mendoza’s hypothesis is that the plastic in the Great Lakes starts small, possibly as scrubbing beads in household or beauty products, facial scrubs and even some toothpaste.”

Visitors to Jens Jensen Park in the Chicago suburb of Highland Park will notice a change to the landscape this year. The Fountain of the Blue Heron, nestled between the park’s grassy land and thick forestry, has been transformed into a water garden. But this is no ordinary water garden. Like much of the park surrounding it, this garden was built with plants that are native to northeastern Illinois.
The fountain was redesigned by the Park District of Highland Park and the Chicago Botanic Garden, with funding assistance from Illinois-Indiana Sea Grant, to give park visitors a closer look at how native aquatic plants like lizard’s tail, water willow, and sweet flag can be used to create beautiful, healthy water gardens.
“Native plantings have gotten a bit of a bad rap,” said Bob Kirschner, director of restoration ecology at the Chicago Botanic Garden. “They are often seen as weedy and unorganized. We wanted to demonstrate how you can use native aquatic plants to achieve the ornamental look many people desire.”
Using native aquatic plants like those in Jens Jensen Park is about more than just creating striking water gardens, though. Growing native species also helps curb the spread of invasive aquatic plants that outcompete native species and upset food webs. Invasive species common in water gardens are already threatening the health of Illinois waterways. For example, the fast-growing Brazilian Elodea—typically sold in aquarium stores and water nurseries under the name “Anacharis”—has been found in several lakes and ponds in Illinois, including in a community not far from Highland Park. Like many invasive plants, this waterweed grows in dense mats that block out sunlight needed by other species and hinders water recreation. And it is nearly impossible to remove once it has been introduced.
“Once an invasive species has become established, the negative impacts on the environment cannot be fully reversed,” said Greg Hitzroth, an IISG aquatic invasive species outreach specialist. “By growing non-invasive species, gardeners can help prevent a new population of harmful species from taking root in local environments.”
The over one dozen species of aquatic plants at home in Jens Jensen Park will also provide food for birds, insects, and other wildlife. Native plants are especially important for pollinators like bees and butterflies that keep northeastern Illinois’ natural areas flowering.

Katherine Touzinsky, a graduate student at Purdue University and 2014 Knauss Fellowship finalist, set out to prove to skeptics that Asian carp really does taste great. The taste test was held in conjunction with the Houston Bowfishing Classic tournament along the Wabash River outside Lafayette, Indiana.
Katherine and Angie Archer, fellowship specialist with IISG, served up tasty fried fish strips which Katherine calls “silvertips”, a wordplay combination of silver carp and wing tips. Many of the bowfishermen have caught Asian carp but had never tried this mild white fish. After watching friends enjoy the crispy fish, they were encouraged to grab a piece. The reactions ranged from “so-so” to “delicious,” with a few coming back for seconds (and even thirds).
The Houston Bowfishing Classic shoots are in their eighth year and are quickly gaining in popularity and notoriety among Midwestern bowfisherman. Katherine’s project, entitled “Winning Back the Wabash—Clean ‘em Out and Cook ‘em Up,” was funded by a Purdue Sustainability Office grant. The goal of the grant project is to help foster environmental stewardship and invasive species control through outreach and active engagement of community members. To help with control, the tournament offered an award to the most silver and bighead carp caught by a team, and another award for the biggest fish (by weight). The 14 teams hauled in 171 Asian carp, with the biggest silver carp weighing in at 11.3 pounds and a bighead carp that weighed 14.5 pounds.
The Dean John A. Knauss Fellowship, awarded annually through National Sea Grant, provides post-graduates the opportunity to work with legislative and executive branches of the U.S. government in Washington, D.C. for one year. Students who have an interest in oceanic and Great Lakes research or marine policies affecting our natural resources are encouraged to apply.

Back in April, we announced an art contest that asked K-12 students to share their ideas of how Lake Michigan could be protected from Asian carp. The results are now in, and three students in the Champaign area have been crowned the winners.
The awards go to Kylie Jackson, a third grader from Mahomet, and Lindsay Donovan and Nicole Dudley, both kindergarteners from Champaign. Each of their drawings depicts different ways to control the spread of Asian carp by keeping eggs from hatching. Kyle, Lindsay, and Nicole were chosen from 67 entries. Drawings were judged on creativity, artistic design, and relevancy to the topic.
The contest, funded by Illinois-Indiana Sea Grant, is part of ongoing efforts to introduce people to a new modeling tool that resource managers and lawmakers can use to prevent the spread of Asian carp. The model, known as FluEgg, can help decision makers identify where in the Great Lakes the invasive fish could become established. Because carp eggs have to stay afloat to hatch, Asian carp need to spawn in fast-moving streams. In order to thrive in the lakes, they would need access to places where there is a lot of turbulence, such as downstream from dams and spillways. Resource managers can use FluEgg to find those areas where conditions are right and test how effective prevention methods would be.
Developed by University of Illinois researchers Tatiana Garcia and Marcelo Garcia, FluEgg is the first of its kind to consider factors like water temperature and turbulence as well as biological data about early life stages to answer the question of whether Asian carp can become established in the Great Lakes. The model has already revealed that the Sandusky River in Ohio—a tributary to Lake Erie that was though unsuitable for spawning—could be a breeding ground for Asian carp during warm summer months. In the coming months, Tatiana and Marcelo plan to use FluEgg to evaluate more tributaries.

Purdue Day at the Indiana State Fair turned out to be a great place for Illinois-Indiana Sea Grant specialists to show off the Asian carp bag toss game. Fair goers of all ages tried their hand at making the shot, and they got to learn more about invasive Asian carp at the same time.
With each throw, Purdue graduate students Zoe Almeida and Allison Hyrcik and IISG specialists Kara Salazar and Angie Archer quizzed the visitors on facts related to Asian carp. Many were eager to learn more and to find out about actions they could take to control the spread of Asian carp.
Attracting close to a million visitors each year, the Indiana State Fair offered specialists the opportunity to talk with Hoosiers from all areas of the state, from the southern border near the Ohio River to the northern part of the state around Lake Michigan. With so many waterways throughout Indiana, visitors to the booth were interested to learn more about invasive species and steps that could be taken to protect the state’s natural resources.

Aquaculture, the business of raising fish for commercial sale, is a growing part of Indiana’s agriculture practice, and Illinois-Indiana Sea Grant’s Kwamena Quagrainie is just one of the people helping to make that possible.
From Purdue University:
“Estimated sales from Indiana fish farms amounted to more than $15 million in 2012, an increase from $3.5 million in 2006, according to the publication Economic Importance of the Aquaculture Industry in Indiana. There are about 50 fish producers in Indiana, compared with 18 just seven years ago.
‘While aquaculture is not the most well-known industry in Indiana’s agriculture sector, it is definitely present and very important to the state’s economy,’ Kwamena K. Quagrainie, aquaculture marketing specialist in Purdue University’s Department of Agricultural Economics, said in the report. He conducted the study with graduate student Megan C. Broughton.
‘The industry has seen steady growth over the past few years, and it is important to know exactly how much economic activity is associated with aquaculture in Indiana,’ Quagrainie said.
Indiana’s aquaculture industry ranges from small-scale producers raising fish in their backyards to large-scale producers growing fish to sell in national and international markets, the report says. The industry includes production of fish for human food, ornamental fish for aquariums and recreational fish that are stocked in private and public ponds and lakes.”

A collaboration between Illinois-Indiana Sea Grant, the Chicago Metropolitan Agency for Planning, the Metropolitan Planning Council, and several other agencies across Illinois and Indiana, the new Outdoor Water Use Manual is now available from NWPA. Completed as part of a larger goal to help reduce and curb outdoor water use, the manual provides necessary information on discretionary water use, costs to utilities and municipalities, and steps to develop more efficient outdoor water use policies and plans.
The manual comes just as the height of the summer season has led some areas to enact strict watering policies or, in the recent case of Lake Forest, institute a temporary ban on outdoor watering altogether.
Peter Wallers of the NWPA writes on page four of the manual, “The significance of this guide and what separates it from the average lawn care guide is its emphasis on efficient lawn care, using as little water and fertilizer as possible while achieving maximum performance for your lawn.”
By providing information and planning steps for proper water and fertilizer usage, the manual offers not only steps for reducing current use levels, but gives municipalities a way to plan for sustainably meeting their needs well into the future.
For more information about this project and other water usage materials, contact IISG’s Margaret Schneeman.

Last week, IISG’s Anjanette Riley and Laura Kammin set sail on Lake Michigan to learn more about plastic pollution in the Great Lakes. Anjanette wrapped up the trip by writing about the experience:
The sampling process started like many do – with a countdown that sets off a whirlwind of action. On three, some in the 5-person crew would hoist a 4-foot-long trawl overboard while another recorded the time, the boat’s location and speed, and the direction and force of the wind. Another person was responsible for adjusting the sails and the boat’s direction to keep it moving at a slow-but-steady speed. The next 30 minutes—as exact as possible—would be a bit calmer. The trawl skimmed the surface of Lake Michigan, trapping everything that crossed its path in a narrow net. And the crew got ready to process the sample. The real work started when the trawl was pulled from water. Everything caught in the net—large and small, natural and man-made—had to be moved to a plastic bottle so its contents could be examined later. It sounds simple enough, but the netting is small and getting tiny beads of plastic or nearly-microscopic animals into the bottle required a multi-step process that took time. Step 1: use a spray gun to get everything out of the net and into a tightly-woven sieve. Step 2: spray everything to one side of the sieve. Step 3: spoon the larger contents into a plastic bottle. Step 4: drain everything else into the bottle. Step 5: pour in some rubbing alcohol. Step 6: label the plastic bottle with the sample number and tape it up to prevent it from spilling. And repeat.
During the three days Laura and I were aboard the sailboat Free at Last, the crew collected 16 samples from all across southern Lake Michigan. With us on the boat was Stiv Wilson, communications director for the plastics research group 5 Gyres, Nick Williamson, an undergraduate research assistant at SUNY Fredonia, and Conor Smith, the ship captain. Together, we made a triangle from the Chicago area to just south of the Wisconsin border to South Haven, Michigan and back, collecting water samples about every hour and a half.
We found bits and pieces of plastic in several of the samples. Most of what we saw were tiny microbeads, like the kind used as exfoliants in face and body washes. On the second day, though, we pulled a plastic cigarette wrapper from the lake. Beyond the reach of the trawl, we also saw balloons, plastic bags and bottle lids, a straw, and a couple other pieces of unrecognizable plastics riding the waves. But these were just the things large enough to be seen. We won’t know for sure how much plastic is in the lake until Sherri Mason and her research team at SUNY Fredonia examine the samples under a microscope over the next few months.
The findings from this trip will be added to the results of previous research excursions on northern Lake Michigan and each of its sister lakes to get a more complete picture of plastic pollution in the Great Lakes. Initial results have already revealed that the lakes have a higher concentration than some parts of the world’s oceans, where plastics have been a major environmental concern for years. 
Because plastics float and break down very slowly over time, everything from chemical contaminants to bacteria and invasive species can latch on and catch a ride to new ecosystems. These sampling trips are the first to examine whether the Great Lakes may be facing the same ecological threat.
