Michigan Radio’s Here and Now recently discussed the issue of Asian carp and the State of Michigan’s preparations to prevent and fight the spread of the invasive fish.
From WBUR:
“Asian carp, an invasive and destructive fish, have spread through the Mississippi, Ohio, Illinois and Missouri rivers. In total, the fish are affecting more than 20 states from Louisiana to South Dakota.
Under the right conditions, it could take as few as a dozen Asian carp to establish a population in the Great Lakes. That’s according to a report published this month by scientists in Ontario.
If they’re correct, the risk of even just a handful of Asian carp escaping into the Great Lakes could be more significant than officials had planned.
From the Here & Now Contributors Network, Lindsey Smith of Michigan Radio reports on how the Department of Natural Resources in Michigan is getting ready to face off with this invader.”

The Purdue University Department of Forestry and Natural Resources (FNR) celebrated their centennial anniversary from September 20-22, and included back-to-class sessions, tours of FNR buildings including the aquaculture research laboratory, and a Saturday evening banquet. More than 250 guests, including many FNR alumni, joined in the celebrations.
FNR has spent the past 100 years training professional foresters, fishery and wildlife scientists, and natural resource managers who help to preserve and protect environmental resources throughout the country.
Illinois-Indiana Sea Grant (IISG) has proudly partnered with FNR for more than 30 years. Brian Miller, IISG Program Director, said, “The Illinois-Indiana Sea Grant College Program highly values our 30 year partnership between NOAA, Purdue University, and the University of Illinois. This type of bi-state partnership only works in one other Sea Grant college in the country, and only works because of the mission-driven spirit of collaboration that exists on both of our campuses. The innovation, dedication and creativity of FNR have helped make the Illinois-Indiana Sea grant college program successful and enabled us to achieve positive impacts for local communities and the Great Lakes ecosystem.”
Recent IISG work was showcased during a welcome reception Friday night, and IISG staff assisted in organizing several of the celebration events throughout the weekend. Numerous current IISG staff members have worked closely with FNR, including Miller, Angela Archer, Carolyn Foley, Tomas Hӧӧk, Kwamena Quagrainie, and Kara Salazar, and the partnership continues to offer a crucial link in protecting coastal areas and waterways.

Recent research in the Chicago area shows that bacteria are developing a resistance to a common antibacterial chemical used in many household and personal care products.
From The Cary Institute:
“Invented for surgeons in the 1960s, triclosan slows or stops the growth of bacteria, fungi, and mildew. Currently, around half of liquid soaps contain the chemical, as well as toothpastes, deodorants, cosmetics, liquid cleansers, and detergents. Triclosan enters streams and rivers through domestic wastewater, leaky sewer infrastructure, and sewer overflows, with residues now common throughout the United States.
Emma Rosi-Marshall, one of the paper’s authors and an aquatic ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York explains: ‘The bacterial resistance caused by triclosan has real environmental consequences. Not only does it disrupt aquatic life by changing native bacterial communities, but it’s linked to the rise of resistant bacteria that could diminish the usefulness of important antibiotics.'”

Illinois-Indiana Sea Grant’s Caitie McCoy and others have just completed work on a new curriculum for elementary and high school science students.
Helping Hands: Restoration for Healthy Habitats offers lessons and hands-on activities to connect students in the Great Lakes with recent or ongoing cleanup and restoration projects happening in their communities. The range of activities offers new ways to engage students with real-life examples that show environmental science in action.
Teachers interested in having Sea Grant lead the curriculum in their school should contact Caitie McCoy. Caitie can work with the teacher to customize curriculum to meet school-specific needs. The curriculum expands Great Lakes literacy among students, many of whom may become future researchers and educators.
Community leaders in Areas of Concern that would like to help Sea Grant lead or set up an educational program are also encouraged to contact Caitie. The complete curriculum is free to download at the link above.

Recent research indicates that even a handful of Asian carp, between just ten and twenty fish, could establish an ecologically damaging population in the Great Lakes.
From ScienceDaily.com:
“Published this week in the Biological Invasions journal, research from Professor Kim Cuddington of the Faculty of Science at Waterloo indicates that the probability of Asian carp establishment soars with the introduction of 20 fish into the Great Lakes, under some conditions…
‘This species will have a huge impact on the food web,’ says Professor Cuddington. ‘Not only is it a fast-growing fish physically, but the population itself grows very quickly. A female can lay well over a million eggs a year, and with no known predators present in the Great Lakes, the Asian carp could dominate the waters and impact fisheries.’…
Individual fish have already been caught in two of the Great Lakes. The probability of Asian carp establishment changes dramatically if only 10 of the creatures are introduced. With 10 fish, the probability of a population of Asian carp is only 50 per cent, but with 20 fish, it jumps to 75 per cent, under some conditions.”

IISG staff will have the opportunity to see aquaculture in action next week while touring the Bell Aquaculture facility in Albany, IN. IISG’s Kwamena Quagrainie has been studying and providing expert advice to aquaculture operations in the Midwest and worldwide for many years, and will be giving the staff more information on how the facility provides millions of pounds of sustainably grown fish to the market each year.
Aquaculture has been a growing food field in the state of Indiana, and a recent feasibility study funded in part by IISG (available online soon at our research projects page) shows that it may have significant potential in Illinois as well.
Additionally, Purdue University produced this great video about aquaponics, which is an extension of aquaculture where fish and plants are raised sustainably and simultaneously in a mutually beneficial system.

A group of researchers from Purdue University spent a week aboard a research vessel in Lake Michigan, attempting to track and map the way that the currents move and transport marine life and pollutants with them.
“The Great Lakes lack the predictable regularity of tides; a combination of factors including winds, temperature and current depth influence currents. Combined, these factors cause a complex, spiraling water flow, producing a type of interior (rather than surface) waves called inertial waves.
The researchers hypothesize that the inertial waves are the primary mechanism governing the movement and dispersion of particles. ‘You can get currents as strong as a half-meter per second in the middle of Lake Michigan,’ Cary Troy of Purdue’s School of Civil Engineering said prior to the study. ‘The effect is strongest in the middle of each of the Great Lakes, so that’s why we are doing the research there.’
‘The goal is to do dye-release experiments and to track the dye patch over time to see where it diffuses and where it moves and to relate that to the information we have about the lake currents and waves,’ Troy said. ‘One obvious application is for something like an oil spill or any sort of contaminant spill in the Great Lakes. If you have a spill, you need to predict where it’s going to go and how quickly it’s going to dissipate.'”

A recent study of Lake Michigan is indicating a high level of prescription drugs in the water, helping to emphasize the importance of proper disposal and the difficulty that water treatment facilities have removing these compounds.
From MLive.com:
“The study was performed by researchers at the University of Wisconsin-Milwaukee and examined water samples taken near a Milwaukee water treatment plant and from the city’s harbor, Environmental Health News reported.
Researchers found high levels of the anti-diabetes drug metformin, the anti-bacterial drug triclosan and the antibiotic sulfamethoxazole as well as high levels of caffeine in both water and sediment samples taken from the lake. In total, 38 different compounds were found in the samples in some concentration, including acetaminophen, testosterone, codeine and several antibiotics.”

The SeaPerch Program, sponsored by the Office of Naval Research, brings robotics and underwater science together to enhance classroom activities and curricula for a variety of grade levels. Illinois-Indiana Sea Grant recently sponsored a contestto give away several of the kits to teachers of grades 6-12, and the six winners will be receiving their new kits in the coming weeks. Blake Landry, project partner and coordinator of the University of Illinois’ SeaPerch Program, is working with IISG to provide continued support and training to the teachers and their students.
Teachers were asked to complete a survey and provide details about how they wanted to integrate the SeaPerch technology into their science lessons, and the responses were outstanding. In addition to bolstering their own classroom activities, several teachers hoped to use the starter kit and accompanying science lessons to share with teachers throughout the area. One winner wrote, “The SeaPerch program and applications would be an excellent topic to present at the Illinois Computing Educators Conference targeting science teachers and integration of science and engineering.”
In addition to offering a new tool to teachers, the contest helps to further activity and curriculum development and provides educators an opportunity to network and share their ideas with others. All of which complements IISG’s goal of fostering Great Lakes science literacy and engagement throughout the region.
