Opportunities Abound; Volunteer While Doing What You Love!

The warmer weather and open water is calling! When you’re out doing your favorite activities this spring and summer, you could be helping protect your lakes and rivers! Learn about some of the volunteer opportunities at Fox-Wolf below. Our volunteer opportunities give you the flexibility to do what you love while protecting your waters!

Adopt-a-Launch

Join community members in helping improve boat launches ! Interested individuals will adopt a local boat launch and help remove plants from the launch area, pick up litter, and report issues with the launch. Volunteers also help protect our lakes by searching for aquatic invasive species at their launch! Adopt-a-Launch program is a Fox-Wolf program that works to engage community members in taking ownership of their lakes by helping to search for aquatic invasive species and improve boat launches! Get involved today!

Project Riverine Early Detectors

Love to paddle, kayak, or canoe in rivers and streams? Help look for invasive species during this relaxing pastime! You will be trained on how to easily identify aquatic invasive species, some native look-a-likes, and how you can keep an eye out for them when you’re floating just around the riverbend!

Citizen Lake Monitoring Network

Join 1000+citizen volunteers statewide to collect high quality data on the lakes that you love! CLMN volunteers help monitor their lakes for a variety of things including water quality parameters, ice on/off, and aquatic invasive species! Volunteers help determine which topics they are interested in monitoring. The information gathered by volunteers is even used by Wisconsin Department of Natural Resources and university biologists and researchers, UW-Extension, and other interested individuals in projects that work to improve your lake! Help keep track of changes in your lake while being near your favorite Winnebago lake! This opportunity is easy to do from both the shoreline as well as your boat!

Purple loosestrife Biocontrol

Love to garden! This one’s for you! Help control harmful invasive species in our community! The invasive plant Purple loosestrife can quickly dominate a wetland and harm our native plants. You can help by raising a natural predator of Purple loosestrife (Galerucella beetles) on caged, potted, loosestrife plants in your backyard. Once released into local infested wetlands, the beetles only eat purple loosestrife, giving native plants a chance to re-establish. This DNR program, locally coordinated by Fox-Wolf Watershed Alliance, offers free supplies and does not require previous experience. Access to an outdoor space within reach of a garden hose is ideal, but we are also looking for volunteers to help with plant potting and beetle release events.

Clean Boats, Clean Waters

Love talking with people? Get involved in the effort to protect Wisconsin lakes and rivers by stopping the spread of aquatic invasive species. As a volunteer watercraft inspector, you will take up the front line by conducting boater education at boat landings in your community. Inspectors perform boat and trailer checks for aquatic invasive species, educate boaters on how to stop the spread, and collect and report new infestations. Meet other anglers and boaters from across the Midwest!

AIS Statewide Snapshot Day

Want a single day event that’s fun for the whole family? During the statewide Aquatic Invasive Species Snapshot Day, join other water quality enthusiasts in searching for invasive species that harm our waterways. Learn how to search for invasive species that may affect the waters that are special to you. You can choose to search from the shore with binoculars and a rake or wade into friendly waters to get a better look! This event is fun for the whole family and really makes a difference in the fight against invasive species. AIS Snapshot Day occurs on August 10th, 2024.

How To Get Started

Give the greatest gift this year to your waters; your time! Whether you want a single day opportunity or want to help out throughout the summer, we will help you fuel your environmental passions at Fox-Wolf!

Oshkosh, Neenah Play Host Exotic Pet Surrender Events

Original Story: John Moyles, J&R Aquatic Animal Rescue

In an effort to address the challenges of rehoming exotic pets and discourage the harmful practice of releasing them into the wild, J&R Aquatic Animal Rescue hosted several successful Exotic Pet Surrender Events on January 13th and March 2nd, 2024. The event, held at the organization’s rescue center in Neenah, aimed to provide responsible alternatives and a judgement-free environment for pet owners who can no longer care for their exotic animals.

A staggering 460 animals, ranging from fish and reptiles to pet birds and small mammals, found their way to new beginnings through the event. Among the surrendered animals were fish, lizards, snakes, and even a colony of roaches, highlighting the diverse range of creatures in need of assistance.

The event was not only about surrendering pets but also about education and advocacy. Attendees had the opportunity to meet Animal Ambassadors and learn about their unique stories, reinforcing the message of responsible pet ownership. A photobooth with rescued pets allowed for cherished memories to be captured and shared, further fostering a sense of community and compassion.

Collaborating with regional rehoming partners such as Reptile Rescue of Wisconsin, Fox-Wolf Watershed Alliance, Pet Advocacy Network, and University of Wisconsin Sea Grant/Water Resources Institutes, J&R Aquatic Animal Rescue facilitated the surrender of four animals, including fish, a tortoise, and birds. This collaborative effort ensures that these animals are given proper care and attention.

All surrendered pets undergo a brief quarantine and evaluation period to ensure their health and well-being before becoming available for adoption. This meticulous process reflects the commitment of the organizers to find suitable homes for these animals and prevent any negative impact on the local ecosystem.

For those who missed the event, J&R Aquatic Animal Rescue reminds the public that they can surrender pets at their Rescue Center in Neenah or find information about upcoming Surrender Events on their website: https://www.jraar.org/exoticpetsurrenderevents. With 29 events planned for the year there are ample opportunities for pet owners to seek assistance in rehoming their animals.

The success of the Exotic Pet Surrender Event was made possible through the generous sponsorship of Ship Your Reptiles, Chemipure, Jellyfish Art, Reef Aquaria Design, and Festival Foods. Their support enables J&R Aquatic Animal Rescue to continue providing valuable services to the community and promoting responsible exotic pet ownership.

Curious for Management options for your Lakeshore property? Find out more!

Herbicide Treatments: Property Owners Preferences Study

On: February 15, 2024

New Study Finds Negative Emotions Drive Preference for Herbicide Treatments

A new study published by University of Wisconsin-Madison researchers is the first to explore what drives lakeshore property owners’ preferences for herbicide treatments of aquatic invasive plants over other management options, even if those treatments may harm native plants and animals. The study found that negative emotions and believing that aquatic invasive species are present in the lake where a property owner lives were the strongest predictors for preferring herbicide treatments. Surprisingly, perceived impacts of aquatic invasive species did not affect preferences for herbicidal treatment of aquatic invasive species.

These results provide an opportunity for natural resource managers to educate lakeshore property owners about alternative methods for managing aquatic invasive plants while still leaving options open for herbicide treatment, if needed. Other management options include manual and mechanical removal as well as simply monitoring, since non-native plants can often co-exist with other native plants in a lake without taking over and becoming a nuisance.

“People can develop negative emotions about a subject either through lived experiences or through communications about the subject,” said Bret Shaw, lead author and a Division of Extension environmental communications specialist and Department of Life Science Communication professor. “Given that the perceived impact of invasive species is not driving preference for using herbicides, it is possible that fear-based aquatic invasive species prevention messages may influence higher risk perceptions that cause property owners to seek herbicidal treatment first. Considering other approaches and messaging strategies, too, may help lake organizations achieve better outcomes with their management efforts.”

Aquatic invasive plants in Wisconsin lakes can negatively impact recreation and property values. Many organizations offer education and outreach programs for boaters and anglers to prevent invasive species spread. However, some lakes already have non-native species that can become invasive, and new

introductions can occur despite widespread prevention efforts. While there are many ways to manage aquatic invasive plants, lakeshore property owners and lake associations often seek permits to use chemical herbicides even though herbicides themselves can carry a potential risk of ecological harm to the treated lake, which is why herbicides may not necessarily be an appropriate as a first course of action in some waterbodies.

Aquatic invasive species are a concern both globally and in Wisconsin, with the Great Lakes on Wisconsin’s borders and another 15,000 inland lakes within them. While the most problematic invasive species aren’t present in most lakes, where they are located, they can reach high densities that can impede boating, negatively affect fishing and alter the ecological functions of a lake. More than $5 million is spent each year in Wisconsin on aquatic invasive species management. However, even with this annual investment and the negative impacts of aquatic invasive species, very little effort has been spent understanding how waterfront property owners feel and think about invasive species management.

“This research is among the first to understand the opinions and beliefs of waterfront property owners about aquatic invasive species management,” said Tim Campbell, the aquatic invasive species program manager for Wisconsin Sea Grant and co-author of the study. “The results of this research will help us create invasive species management education tools and programs that balance efforts to reduce the unwanted impacts of invasive species while protecting the ecological integrity of our lakes.”

Other co-authors include Dominique Brossard, Professor in the Department of Life Sciences Communication (LSC) as well as recent LSC graduate students, Richard Heinrich (LSC Ph.D. ‘23) and Theresa Vander Woude (LSC and Nelson Institute for Environmental Studies, M.S. ‘21).

Invasive Species Language Workshop designed to get people talking

On: February 8, 2024

Communicating effectively about invasive species, whether the plants and animals are on land or in water, can be challenging. Is it better to “wage a war” on invasives, or should communicators take an alternative approach?

In conjunction with National Invasive Species Awareness Week, the Sea Grant programs in Michigan, Oregon and Wisconsin are hosting a workshop with the North American Invasive Species Management Association on the topic of using messaging and metaphors in communicating about invasion biology. The “Invasive Species Language Workshop,” will be held online and in-person on Feb. 27-28. A virtual half-day of webinar presentations will be followed by a full-day workshop in Washington, D.C., where attendees will draft guidelines and research priorities for inclusive communication and naming conventions. Researchers, science communicators and invasive species managers are encouraged to attend.

“Our goal is to learn what everybody’s doing in their respective fields, and then get everyone together to talk it out and describe any successes they’ve had in advocating for better and more inclusive language about invasive species,” said El Lower, Great Lakes Aquatic Nonindigenous Species Information System communications specialist with Michigan Sea Grant. “It’s about how we can work together to promote a set of best practices and present a unified front across invasion biology.

“We can come up with different metaphors that are not just ‘good versus evil, us versus them,’ and actually get into some of the nuance involved in managing invasive species. Sometimes that gets lost in the wash if you’re simply focusing on military metaphors,” Lower added.

Another issue with invasive species are their names. Some species names may contain racial slurs or reinforce xenophobic concepts. Efforts to develop more inclusive guidelines for naming invasive species have been limited, and this will be an additional focus of the webinar and workshop.

“Scientists and natural resource managers often believe that the language and points they make are neutral; that they’re just the facts. However, even when communicating facts, we all use value-laden language or language that may be received differently than intended,” said Tim Campbell, Wisconsin Sea Grant AIS program coordinator. “By embracing this inclusive language and naming conventions, we can reduce unintended consequences of our communication products, and we be more effective in our aquatic invasive species management efforts.”

Registration is now open for the sessions. Visit the website here.

Funding for the workshop was provided by the National Sea Grant Office.

Once They Were Pets. Now Giant Goldfish Are Menacing the Great Lakes.

Released Goldfish Grow to Monstrous Size, Destroy Habitat

Original Story: Livia Albeck-Ripka, The New York Times

Inside a fishbowl, the goldfish — a species of carp native to East Asia, bred for aesthetic delight and traditionally believed to bring good fortune — is hardly more than home décor. Usually just a few inches long, it is among the easiest of pets to keep.

But released into the wild, the seemingly humble goldfish, freed from glass boundaries and no longer limited to meager meals of flakes, can grow to monstrous proportions. They can even kill off native marine wildlife and help destroy fragile and economically valuable ecosystems.

“They can eat anything and everything,” said Christine Boston, an aquatic research biologist with Fisheries and Oceans Canada.

Over the past several years, Ms. Boston and her colleagues have been tracking invasive goldfish in Hamilton Harbour, which is on the western tip of Lake Ontario, about 35 miles southwest of Toronto. The bay has been decimated by industrial and urban development as well as by invasive species — making it among the most environmentally degraded areas of the Great Lakes.

Their study, published last month in the Journal of Great Lakes Research, could help pinpoint goldfish populations for culling, said Ms. Boston, who is the lead author. “We found out where they are before they start spawning,” she said. “That’s a good opportunity to get rid of them.”

The fast-growing female goldfish, Ms. Boston noted, can also reproduce several times in one season. “They have the resources,” she added, “and they can take advantage of them.”

Goldfish were first spotted in Hamilton Harbour in the 1960s, but largely died off in the 1970s because of industrial contamination. In the early 2000s, their population appeared to recover. Goldfish can tolerate a wide range of water temperatures, reach sexual maturation quickly, and can eat nearly anything, including algae, aquatic plants, eggs and invertebrates, Ms. Boston said.

The feral goldfish are also destructive, uprooting and consuming plants that are home to native species. They help spawn harmful algal blooms by consuming the algae and expelling nutrients that promote its growth, Ms. Boston said, creating conditions that are intolerable to native fish.

To track the goldfish, the researchers captured and sedated 19 of the larger adults and surgically implanted tags the size of AA batteries into their bellies. The tags, which sent signals to acoustic receivers around the bay, provided researchers with a map of their locations.

Eight of the fish died, but the remaining 11 led Ms. Boston and her colleagues to find that the fish tended to spend the winter in deep waters and moved to shallower habitats by spring, where they prepared to spawn.

Some options for removing the goldfish, she said, include capturing them with specialized nets deployed beneath winter ice, or using “electro fishing,” which involves stunning the fish with an electrical current and scooping them from the water. Both techniques, she added, would avoid killing the native fish.

Nicholas Mandrak, a professor of biological sciences at the University of Toronto Scarborough, said that while goldfish were introduced to North America in the late 1800s, the wild population had begun to “dramatically increase” in the past two decades. Their spawning explosion, he said, resulted partly from people in densely-populated areas releasing pets in urban ponds.

Climate change may play a role, because of the goldfish’s capacity to adapt to warming and poorly oxygenated waters, he added.

“There are literally millions of goldfish in the Great Lakes, if not tens of millions,” Dr. Mandrak said.

Despite the threat, he added, environmental managers tend to forget the goldfish. “They just assume, ‘It’s been there for 150 years — there’s nothing we can do about it.’”

The problem is not unique to Canada. In Australia, a handful of unwanted pet goldfish and their offspring took over a river in the country’s southwest. Feral goldfish have flooded waterways in the United Kingdom, and, in Burnsville, Minn., the discovery of football-size creatures in a lake in 2021 led officials to beg their constituents: “Please don’t release your pet goldfish into ponds and lakes!”

People wrongly believe that because goldfish are “small and cute” they won’t pose a problem when released into the wild, said Dr. Ricciardi. “It’s the ‘Free Willy’ syndrome.”

Goldfish, he added, are just a small part of a vast invasion of non-native species whose outcomes can be unpredictable, and in some cases, are worsened by climate change.

“Under human influence, beasts are moving faster farther in greater numbers, reaching parts of the planet they could never reach before,” he said. “We’re talking about the redistribution of life on Earth.”

Anthony Ricciardi, a professor of invasion ecology at McGill University in Montreal, noted that not all invasive goldfish become supersized, but even the small ones are problematic, outpacing native fish populations and damaging the environment.

Their football-shaped bodies can swell to a size that makes them too large a meal for predators — up to about 16 inches long. “A fish would have to have a really big mouth to eat it,” she said.

Twenty-four animals were turned in at an exotic pet surrender event at the Ledgeview Nature Center in Calumet County on Sunday December 3rd. Included in the surrenders were a blue-tongue skink, two bearded dragons, 18 guinea pigs, a chameleon and two yellow bellied sliders!

Area organizations were on hand accepting fish, invertebrates, reptiles, pet birds, small mammals, and plants — no questions asked.

In some areas, there are no rehoming options for exotic animals such as fish, birds, and reptiles. Some pet owners that are unable to care for their pet may think that releasing the animal is the right thing to do, however, releasing a pet is harmful for the animal and the environment. Pet Surrender events are now being held across Wisconsin help provide an avenue to pet owners to rehome pets without harming the pet or the environment.

There are multiple places that are currently tackling issues from illegally released domestic and exotic animals. The most well known example are the Burmese pythons that have had an enormous impact on the Everglades in Florida. However, multiple cases of released pets causing problems in our waters occur every year including an alligator found on the shores of Lake Michigan just a few weeks ago! Released pets can easily become nuisance or invasive species if they start a breeding population.

The Pet Surrender event brought together a collection of area rehoming partners that provide responsible alternatives to release for exotic pet owners who are no longer able to care for their pets. J&R Aquatic Animal Rescue (JRAAR) hosted the December 3rd th event with help from the Fox-Wolf Watershed Alliance and University of Wisconsin Sea Grant/Water Resources Institutes.

South Milwaukee Police find Gator in Grant Park

Original Story: We Are Green Bay

Alligators are native to the southern portion of the United States, which has officials questioning how one ended up on a beach in Wisconsin. According to the South Milwaukee Police Department, officers took a report of an alligator on Lake Michigan Beach in Grant Park.

The Milwaukee Area Domestic Animal Control Commission (MADACC) was also called to the scene to assist in taking the alligator into custody safely. Officer Lewison with the South Milwaukee Police Department was able to locate and take the alligator into custody safely. The gator is now in the hands of MADACC.

It’s been quite the last few months for Wisconsin’s lakeshore, as just two months ago in September, five flamingos showed up at a Port Washington beach. Additionally in August, an ultra-rare Roseate Spoonbill was spotted in Green Bay for the first time in 178 years.

Judging from the size of the alligator, it looks like it was an illegal pet release. While folks may not know what to do with pets that they are no longer able to care for, pets should never be released into the wild. Places like the J&R Aquatic Area Animal Rescue can help rehome your pet at no cost. Make sure your pet isn’t the next one on the evening news!

Take 5 Minutes Each Hunt for Invasive Species Prevention

Original Story: WDNR

Invasive species are nonnative plants, animals and diseases that cause great ecological, environmental or economic harm. Some have already been found in Wisconsin, while others pose a large risk of surviving and causing problems if they are introduced and become established here.

Just a few minutes of preventative action can help preserve and protect hunting lands for generations to come.

Before launching into and leaving a waterbody, waterfowl hunters should:

– Inspect waders, boats, trailers, motors and hunting equipment, including boots, blinds and dogs

– Remove all plants, animals and mud to the best of their ability

– Drain all water from decoys, boats, motors, livewells and other hunting equipment

– Remove all seed heads and roots when using vegetation for duck blinds

– Never move plants or live animals, such as snails, away from a water body

Lots of hunting spots have boot brush stations to help you clean off your gear (see picture). Want to have one installed at your favorite hunting spot? Contact Chris using the info below!

As we start see leaves drop, lots of folks are starting to prepare their homes and gardens for winter. If you’ve got a water garden, you’ll be starting to do the same thing! Water gardens make a great addition to any landscape masking unwanted noise, inviting songbirds to take a drink, and providing a beautiful oasis in any landscape. Fall is the time to prepare your water garden for winter. Tropical plants need to be moved indoors and aggressive or invasive plants should be removed and disposed of properly. Contact your local municipality for tips on disposing these and your local Department of Natural Resources for a list of invasive plants in your area that need to be removed. Eliminating invasive plants from our landscapes helps keep them out of our lakes and waterways!

With a history of popular water garden plants being released in our region, following these steps is an easy way to be a steward for your local waterways and your water garden!

Original Story: Water Action Volunteers

On August 19^th, 2023, water lovers of all ages gathered for a one-day statewide aquatic invasive species (AIS) scavenger hunt as a part of the 10^th annual AIS Snapshot Day. This event is coordinated by UW Extension in partnership with River Alliance, the Wisconsin Department of Natural Resources (WDNR), and Extension Lakes. Volunteers met at different local rendezvous sites across the state to learn how to identify AIS such as Eurasian watermilfoil, purple loosestrife, and New Zealand mudsnails, and then searched for them in the field at pre-selected locations. Initially focused on rivers and streams, Snapshot Day has expanded to include lakes and wetlands. Findings from Snapshot Day are uploaded to the statewide water quality database, SWIMS, where they can be used to track the spread of invasive species and develop management plans.

Every year, Snapshot Day provides a vast amount of AIS data to the WDNR to assist in management decisions, and this year was no exception! 145 participants gathered across 22 meeting locations and monitored 131 sites across 102 different waterbodies in Wisconsin. 48 of those waterbodies had no AIS detected. At 83 sites, volunteers located 15 different AIS species, including purple loosestrife, curly-leaf pondweed, Asian clams/freshwater golden clams (Corbicula), and faucet snails.

Snapshot Day’s community-based science approach maximizes the number of sites being checked across the state, and the free event allows volunteers to learn about their local waters and how to keep them healthy. As one volunteer stated, “I enjoyed the hands on learning approach. It was helpful to have well informed guides and samples of the invasive species to get a close look at. Once we had a good understanding of what to look for, it was fun to go out and collect samples of what we were finding.”

We would like to extend a HUGE thank you to all of the volunteers, partner organizations, and site leaders who made this event possible.

Invasive European Frogbit Mapping and Control Work Ongoing

The Fox-Wolf Watershed Alliance has partnered with the Wisconsin Department of Natural Resources, Brown County, and other local partners to confront an invasive species in the Bay of Green Bay. European frogbit was first discovered in the wild in Wisconsin late last summer and the known general extent at that time ranged from the City of Marinette to the City of Oconto. Additional monitoring by partners found additional populations within and beyond that range reaching all of the way to the Brown and Door County.

To help reduce the population in the Green Bay area, Fox-Wolf is assisting in monitoring and control work for European Frogbit (EFB). Our aquatic invasive species coordinator Chris is joining partners on large group work days to find and remove EFB. One of the recent large group work days was filmed by Dan Larson from Com-Video Productions as part of a documentary on Green Bay; the same producer that brought you the documentary Power of the River. Check out his clip of our European Frogbit monitoring days below!

The free-floating European Frogbit is native to Europe, Africa, and Asia. It likes slow-moving habitats like sheltered inlets, rivers, and ditches. The plant resembles native water lilies but is much smaller and doesn’t root in the lake bottom. The plant forms dense mats that can interfere with boaters and shade-out native plants. If you see European frog-bit, take a few photos, make note of the location, date and time of the finding, and report to Amanda Smith, WI DNR Regional Invasive Species Coordinator.

Wisconsin residents invited to help search Wisconsin’s waters for invasive species on August 19^th

Water lovers of all ages are invited to join the statewide search for aquatic invasive species (AIS) on August 19^th, 2023. This fun, hands-on effort, known as AIS Snapshot Day, relies on participants to monitor streams, lakes, and wetlands at designated sites across the state, for signs of non-native plants and animals that pose risks to Wisconsin waterways and wildlife. Volunteers have a choice to register at one of over twenty event locations hosted by local conservation groups.

Coordinated in partnership by UW-Madison Division of Extension, UW-Stevens Point Extension Lakes, River Alliance of Wisconsin, and the Wisconsin Department of Natural Resources, Snapshot Day is entering its’ 10th successful year. Information collected will be provided to the Wisconsin Department of Natural Resources to inform and guide monitoring and response efforts. Volunteers are key to the success of the event.

“Projects like AIS Snapshot Day are a fun and simple way for volunteers to get engaged and for the local site leaders and DNR to collaborate” says Maureen Ferry, DNR AIS Monitoring Coordinator. “DNR has a long list of sites with suspected but unverified AIS that AIS Snapshot Day monitoring targets. This increases the chances of volunteers finding a species. Plus, each year, we make new detections.”

Last year over 150 volunteers rolled up their sleeves to monitor at more than 234 sites across the state making for a fun and safe event.

This is a free event. Recommended for ages 8 and up, minors must be accompanied by an adult.

Gardener Extraordinaire Melinda Myers Gives Insight into Japanese Knotweed

During last month’s National Rivers Month, Melinda Myers took a moment to highlight the over 3.5 million miles of rivers and streams in the United States. In addition to outlining the amazing things our waters do for us (including supplying water for drinking and for irrigating crops), Melinda brought attention to a riverside invasive species; Japanese knotweed. This plant was original brought to America as an ornamental but quickly spread through much of the United States. With bamboo-like stems, this invasive plant is known to choke waterways and hasten erosion. If you are one of the folks who has Japanese knotweed growing along your shorelines, there are great control options available.

To learn more, including control methods, check out this Japanese Knotweed brochure: https://widnr.widen.net/s/jzxjqrs867/wy0090?fbclid=IwAR2q36KUKGAJ4NJfAZ7N8S6MOeOgx-NPEV1T-LD3lzp6nMdXFvRWum-ssKQ

American Fisheries Society honors journal article based on Sea Grant-funded research

The 2021 publication advanced understanding of VHSV, an invasive pathogen affecting fish, in Wisconsin waters

A journal article that grew out of Wisconsin Sea Grant-funded research has been honored with a Publications Award from the American Fisheries Society (AFS), presented today at the society’s annual meeting in Spokane, Washington.

The society honors one outstanding paper from each of its journals annually with this award. “Widespread Seropositivity to Viral Hemorrhagic Septicemia Virus in Four Species of Inland Sport Fishes in Wisconsin” was published last year in the Journal of Aquatic Animal Health. Its authors are Whitney A. Thiel, Kathy L. Toohey-Kurth, David Giehtbrock, Bridget B. Baker, Megan Finley and Tony L. Goldberg.

In this July 2016 photo taken near Wauzeka, Wis., Whitney Thiel draws blood from a brown trout while Tony Goldberg observes. (Photo: Bryce Richter, UW-Madison)

The team’s work revealed a more accurate and complex picture of Viral Hemorrhagic Septicemia Virus (VHSV) than previously understood. They found evidence of VHSV farther inland than anticipated, as well as “hot spots” and “not spots”—affected and unaffected bodies of water—that were surprisingly close together.

Said Thiel, who completed her master’s degree at UW-Madison in 2019, “I was surprised and flattered when I heard about the award. What a great feeling to know our research, something we all worked so hard on for so many years, is appreciated by the scientific community.”

In addition to serving as the paper’s first author, Thiel presented the group’s work at the Great Lakes Fish Health Committee meeting last year, where it was well received. “I think others are grateful for the insights into inland VHS prevalence that this wide-scale surveillance effort has provided,” she said.

Goldberg, who holds the John D. MacArthur Chair in the Department of Pathobiological Sciences at the UW-Madison School of Veterinary Medicine, also noted that the publication sparked discussion with others in the field. “I suspect it was an eye opener because it changed our vision of what VHSV is, from a lethal and geographically restricted pathogen to a sometimes not-so-lethal pathogen with a far wider distribution than originally suspected.”

For the study, blood samples were drawn from fish in a non-lethal way. (Photo: Bryce Richter, UW-Madison).

The work has implications for mitigating the virus’ spread. Said Goldberg, “VHSV is not ‘everywhere.’ Rather, there are antibody-negative water bodies very close to antibody-positive water bodies, so the risk of spread is still there. In other words, our paper should not be interpreted as an excuse to throw up our hands. There’s still a lot of prevention that can be done.”

Looking ahead, he anticipates that researchers working in other regions will find similar patterns in VHSV occurrence. In the meantime, Goldberg is pleased by the AFS honor and credits former graduate student Thiel’s role in the effort. “I’m very proud of what Whitney did during this project. There’s no doubt in my mind that we would not have been able to do a study like this without a stellar–and Sea Grant-funded–student like Whitney.”

NOAA Sea Grant Liaisons address critical research areas across federal agencies

On: September 8, 2021

In: AIS, aquatic invasive species, NOAA federal liaisons, Tim Campbell, USFWS

NOAA Sea Grant, in collaboration with U.S. Department of Defense, U.S. Department of Energy, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, and U.S. Geological Survey, announces six new partnership positions. The Sea Grant Federal Partnership Liaisons will integrate Sea Grant extension expertise with science, products and services from NOAA labs and other publicly supported scientific research programs. These jointly-funded positions expand on a key component of Sea Grant’s work, extending science to end users and doing so through collaborative partnerships.

“The Sea Grant Liaisons provide strong connection points between emerging research and interested parties to tackle some of coastal and Great Lakes communities’ most pressing issues,” stated Dr. Jonathan Pennock, director of NOAA’s National Sea Grant College Program. “By engaging user communities around the country, Sea Grant’s Federal Partnership Liaisons program harnesses the Sea Grant network’s strengths to inform the work of federal science and service agencies.”

Focus areas for the new liaisons include aquatic invasive species, climate resilience, offshore wind energy, aquaculture opportunity areas, harmful algal blooms and community science for underserved communities. They join three existing Sea Grant partnership liaisons who work in ocean acidification, tsunami and coastal resilience, and Great Lakes research with NOAA’s Pacific Marine Environmental Laboratory and NOAA’s Great Lakes Environmental Research Laboratory.

The positions announced today are the result of a competitive funding opportunity announced in 2020. These Federal Partnership Liaisons are as follows:

Aquatic Invasive Species Liaison, with Wisconsin Sea Grant and U.S. Fish and Wildlife Service;
Coastal Resilience Liaison, with Georgia Sea Grant and U.S. Department of Defense;
Community Science Liaison, with Louisiana Sea Grant, Lake Champlain Sea Grant, U.S. Environmental Protection Agency, U.S. Geological Survey, NOAA Office of Education and NOAA Fisheries;
Harmful Algal Bloom Liaison, with Florida Sea Grant, NOAA’s National Centers for Coastal Ocean Science and NOAA’s National Environmental Satellite, Data, and Information Service;
Offshore Wind Energy Liaison, with Rhode Island Sea Grant and U.S. Department of Energy; and
Shellfish Aquaculture Liaison, with Connecticut Sea Grant and NOAA Fisheries Office of Aquaculture and Milford Laboratory.

Wisconsin Sea Grant’s Tim Campbell will serve as one of the new liaisons. (Photo: Wisconsin Sea Grant)

Wisconsin Sea Grant’s Aquatic Invasive Species Outreach Specialist Tim Campbell will be the AIS Liaison. He will serve in this capacity part-time while continuing his current role with Wisconsin Sea Grant. As a liaison, he will work broadly on AIS outreach coordination for the Aquatic Nuisance Species Task Force, co-chaired by USFWS and NOAA. He will also work to strengthen Sea Grant connections with the regional aquatic nuisance species panels and assist with AIS work in the National Sea Grant Office.

In addition to closely aligning with Sea Grant strategic goals and Sea Grant Network Vision Plans, the Liaisons support shared priorities in sustaining coastal and Great Lakes communities. These positions will build on agencies’ efforts to address three of the Biden Administration’s Executive Orders, “Executive Order on Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis”, “Executive Order on Tackling the Climate Crisis at Home and Abroad” and “Executive Order On Advancing Racial Equity and Support for Underserved Communities Through the Federal Government.”

“EPA is excited to work with our federal partners to address critical water research needs in coastal communities,” said Dr. Wayne E. Cascio, Acting Principal Deputy Assistant Administrator for Science in EPA’s Office of Research and Development. “By working directly with communities, we can increase scientific knowledge and promote more inclusive public engagement in priority environmental concerns, including environmental justice and climate change.”

The Sea Grant Liaisons will serve as a resource to the public, helping to engage and educate communities. Learn more about Sea Grant’s Federal Partnership Liaisons here.

New research provides guidance for effective public messaging about invasive species prevention

On: August 20, 2021

In: AIS, aquatic invasive species, Bret Shaw, invasive species, science communication, Tim Campbell

You could say that preventing the spread of aquatic invasive species (AIS) is a team sport. While it takes the professional efforts of natural resource managers, AIS specialists and others in the environmental field, it also takes the cooperation of the public.

Professionals encourage and rely on boaters, anglers and other outdoor enthusiasts to take preventative actions such as cleaning, draining and drying their boats and other watercraft and not moving water or live bait from one lake to another. Successful management of AIS and the help of a vigilant public go hand in hand.

Yet for community members to take necessary actions, they must first be aware of the negative impacts AIS can have and how to stop their spread. Communicating with them about AIS in an effective way is vital.

New research from Wisconsin Sea Grant Aquatic Invasive Species Outreach Specialist Tim Campbell, University of Wisconsin-Madison Associate Professor Bret Shaw and consultant Barry T. Radler sheds new light on such communication. The researchers analyzed which communication strategies are most effective and which may pose unintended problems. Shaw is a faculty member in the Department of Life Sciences Communication and is also an environmental communication specialist in the university’s Division of Extension.

The team’s findings were published online Aug. 14 in the journal Environmental Management (“Testing Emphasis Message Frames and Metaphors on Social Media to Engage Boaters to Learn about Preventing the Spread of Zebra Mussels”).

This advertisement is an example of the “science” message framing–a straightforward, factual approach. (Artwork by Brooke Alexander)

The trio used Facebook as a platform to test five types of messages—each invoking a different metaphor or message frame—to educate people about zebra mussels, a significant problem in the Great Lakes and elsewhere. These communication strategies can shape how people understand and form opinions about complex issues.

Paid advertising on Facebook and the social media site’s message-testing feature enabled the researchers to present these different messages to 270,000 people in Wisconsin with an interest in lakes, boating or fishing.

Although the ads presented messages similar to those commonly used in invasive species communication, up until this point little testing had actually been done about their effectiveness. The commonly used message frames were dubbed hitchhiker, militaristic, nativist, science and protective. The messages were paired with artwork by Brooke Alexander.

Many communication goals, the team found, can be achieved by using fact-based or more positive message frames. In general, the science frame—a direct, factual approach—will always perform at least as well as nativist and militaristic frames.

Said Campbell, “This work provides real-world results that can help those working with invasive species achieve their desired communication results, while avoiding possible unintended consequences from their messaging.” For example, nativist message framing (e.g., “alien,” “exotic”) can have unwanted xenophobic connotations while also not performing better than other frames on any tested metric.

Militaristic message framing can be fraught with unintended connotations. (Artwork by Brooke Alexander)

Similarly, militaristic framing (such as stating we are “at war” with invasive species) can create potentially unhealthy relationships with nature and misguided views on how to manage invasive species.

Shaw noted that the metrics tested for the Facebook ads included cost-per-click, shares and comments. As he explained, “Many scholars and AIS professionals have debated the use of nativist or militaristic language in prevention campaigns, since many of them find that language to be fraught with unwanted implications. Based on our research, we recommend that outreach professionals skip those nativist and militaristic frames and focus instead on clearly communicated science.”

The team’s journal article may be read online. The research was supported by Wisconsin Sea Grant and the University of Wisconsin-Madison Division of Extension.

McComb’s position focuses on Kenosha, Racine and Milwaukee counties, where he will coordinate education, monitoring and outreach programs for communities, stakeholders and volunteers to prevent the spread of AIS. His office is located at the Kenosha County Center in Bristol, though he anticipates spending a significant amount of time in the field in the three counties.

The three main programs McComb will focus on are the “Clean Boats, Clean Waters” campaign, a purple loosestrife biocontrol program and a citizen lake monitoring program. When possible, he’ll also have a presence at local and regional events (like Racine’s Salmon-A-Rama in July) to help spread the word about AIS prevention and answer the public’s questions.

McComb is eager to engage with a wide range of people. “Honestly, I feel like everyone under the sun is my stakeholder!” he laughed. He will partner with lake or homeowners’ associations that monitor bodies of water, government entities like parks departments, volunteer groups, conservation corps and individuals with an interest in maintaining healthy ecosystems for future generations.

He’s also keen to work with people of different ages. “I’d really like to engage youth and the diversity of cultures and backgrounds in this region. There are so many great groups and people to connect to,” said McComb.

As the summer recreation season gets underway and people head out for boating, fishing and other outdoor pastimes, McComb stressed the basics of protecting our waters, such as the “Inspect—remove—drain—never move—dispose” motto. People should inspect their boats, kayaks or other watercraft for aquatic plants and animals; remove any that are found; drain water from live wells and other areas; never move water, plants or animals between waterbodies; and dispose of unused bait in the trash.

Additionally, he said, “Just be curious and keep your eyes open with what’s going on in the different lakes that you use. You don’t need to be an expert on aquatic vegetation to see a species start to take over, and there’s a whole bunch of people—including myself and DNR folks—who are here to help you identify something if you think it’s an invasive.”

McComb grew up in the Madison area and earned a bachelor’s degree in geography from the University of Wisconsin-Milwaukee. He then spent several years in Utah, where he completed a master’s degree in bioregional planning and worked in planning and conservation.

Said Tim Campbell, Wisconsin Sea Grant’s aquatic invasive species outreach specialist, “Scott has a lot of experience helping communities plan and implement projects that help them improve their communities. I look forward to seeing how that experience helps him build upon existing local partnerships in southeast Wisconsin to improve aquatic invasive species prevention and management.”

A desire to be closer to family brought McComb and his wife back to Wisconsin. In their free time, they enjoy canoeing, kayaking and simply being out in nature.

As McComb settles into his new role, he encourages people seeking AIS information to get in touch. He can be reached at 608-890-0977 or McComb@aqua.wisc.edu.

Research reveals a more accurate picture of the occurrence of VHSV in Wisconsin waters

On: April 7, 2021

In: AIS, David Giehtbrock, Lake Winnebago, pathogens, Tony Goldberg, VHS, VHSV, viral hemorrhagic septicemia, Whitney Thiel

Wisconsin Sea Grant-funded research is revealing a more detailed picture of the range of viral hemorrhagic septicemia virus (VHSV) in Wisconsin waters. This invasive pathogen can cause affected fish to die. Since the early 2000’s, it has caused deaths in more than 30 fish species in the Great Lakes region.

The researchers’ findings have been published in the Journal of Aquatic Animal Health, a publication of the American Fisheries Society. The findings show that VHSV in Wisconsin can be found further inland and in more bodies of water than previously known.

Authors of the research paper (“Widespread Seropositivity to Viral Hemmorhagic Septicemia Virus in Four Species of Inland Sport Fishes in Wisconsin“) are Whitney A. Thiel, Kathy L. Toohey-Kurth, David Giehtbrock, Bridget B. Baker, Megan Finley and Tony L. Goldberg.

They key to discovering this new information was testing fish for the presence of antibodies to VHSV through a process known as enzyme-linked immunosorbent assay (ELISA). While the general method of ELISA is not new, the particular ELISA for VHSV is, and it was developed with Sea Grant support. “It’s a valuable tool in fish health testing,” said Goldberg, an epidemiology professor at the University of Wisconsin-Madison School of Veterinary Medicine.

While other, more common testing methods look for presence of the live virus, the new method detects past exposure to VHSV, which, said Goldberg, is “really useful for screening populations and looking back in time.” Blood samples are collected from fish in a non-lethal way.

The research team focused on four sport fish that are economically important in Wisconsin: bluegill, brown trout, northern pike and walleye. Fish with VHSV antibodies were found in 37 of 46 inland water bodies tested, including water bodies far from known outbreak events. Sampling occurred in 2016 and 2017.

Researchers found the results surprising. Said Thiel, first author of the journal article, “I suspected we’d see it spread out in some of the inland water bodies connected to the Winnebago watershed or the Green Bay area—where we already knew VHS was—but I didn’t expect we would see it so far inland.” Thiel completed a master’s degree in freshwater and marine sciences at UW-Madison in 2019 and is now a research scientist at the University of Idaho.

Another intriguing finding was what members of the team characterized as “hot spots” and “not spots,” which were often close together. Prior to the research, they expected that any additional instances of VHSV detected would be near bodies of water known to have problems. However, in a number of cases, a body of water with no evidence of VHSV could be found neighboring one with evidence of the virus.

Giehtbrock, fish culture section chief at the Wisconsin Department of Natural Resources, said that this new information was all the more reason for those using Wisconsin’s waters—like recreational boaters and anglers—to keep taking preventative steps against the spread of aquatic invasive species in general.

“We need to continue all those practices that have been in place for a long time, to mitigate any transfer of VHSV between bodies of water, which is what we were already asking people to do everywhere. From invasives like Eurasian watermilfoil to carp to VHSV, we’re already asking people to clean their boats, drain their live wells and not transfer water between bodies of water,” said Giehtbrock.

“What people should take away from this is, we want to keep it out of where it’s not,” echoed Goldberg.

Giehtbrock, who supervises DNR fish hatcheries around the state, does not foresee a change in fish stocking practices at this point. Citing both Department of Agriculture regulations and the DNR’s own policies, he said that managing the health of fish for stocking is already strictly controlled.

Blood samples were drawn from fish in a non-lethal way. In this 2016 photo, a sample is taken from a brown trout. (Photo: Bryce Richter, UW-Madison)

“VHSV is one big component of that,” explained Giehtbrock. “We do virus testing on all of the stocks prior to their departure from the hatchery for stocking. So in terms of actual stocking practice, I don’t see a change because we’re already doing all the testing and monitoring that is feasible to make sure that everything we put out there is healthy and not spreading disease.”

Where Giehtbrock does see a possible change, however, is on the demand side, if more fish are needed to maintain or supplement fisheries being affected by VHSV fish kills. However, such a situation has not occurred yet.

This new information paints a more accurate and complex picture of VHSV in Wisconsin than previously understood. The research team recommended vigilance against potentially spreading the virus or other invasives. The best offense is a good defense, such as adhering to current advice promoted by the “Clean Boats, Clean Waters” campaign and similar initiatives.

A series of informal, interactive science presentations on Great Lakes issues will return in spring 2021 with new topics and speakers.

Wisconsin Sea Grant’s “Lake Talks” series highlights topics related to Lake Michigan or, more widely, the Great Lakes basin. Spring talks will be offered through Zoom in light of the ongoing pandemic.

The spring series kicks off on Thursday, March 18 at 7 p.m. with “What cartoon zebra mussels taught me about invasive species communication.” (Register now for this Zoom webinar.)

The speaker is Tim Campbell, Wisconsin Sea Grant aquatic invasive species outreach specialist. Campbell will discuss how metaphors—such as aquatic invasive species as “hitchhikers” or “invaders”—affect how people perceive the issues, and how certain metaphors pose ethical issues or may not lead to productive engagement.

As Campbell explained, “People use many different message frames and metaphors when talking about invasive species, and we know that metaphor use can affect how people understand complex issues. We wanted to better understand how these communication strategies impact actions people might take in regards to invasive species.”

Because preventing the spread of aquatic invasive species (AIS) depends significantly on public cooperation, communicating with the public in an effective way is highly important. Learn what Campbell and his fellow researchers discovered through work that was funded by Wisconsin Sea Grant. The research focused on communication about zebra mussels.

The Lake Talks series will continue with talks in April, May and June. Those future talks will address PFAS (contaminants in our waters often referred to as “forever chemicals”), tourism in the Great Lakes and rip current safety.

On: August 31, 2020

In: AIS, Brandon Falish, Cadie Olson, Chris Litzau, Eat Wisconsin Fish, Green Bay, Lake Talks, Molly Bodde, public events, Titus Seilhimer

Topics include aquatic invasive species, eating local fish and Green Bay’s ecosystem

Wisconsin Sea Grant’s “Lake Talks” series of free, public events will return this fall—in cyberspace. Four virtual events in the series will take place on Thursdays at 7 p.m. between Sept. 10 and Nov. 12.

The series was launched earlier in 2020 with an in-person event in Green Bay in early March. However, remaining spring events were canceled due to public health concerns surrounding the coronavirus. Now, because of ongoing health concerns and university policy, the series will move to a virtual format this fall. Wisconsin Sea Grant is headquartered at the University of Wisconsin-Madison.

The Lake Talks cover topics of special interest to residents in communities along or near the Lake Michigan shoreline—though anyone is welcome to attend.

Fall speakers and topics are:

Sept. 10: Molly Bodde of Kenosha, Wisconsin Sea Grant aquatic invasive species outreach specialist for southeast Wisconsin, will present “But It’s So Pretty: Combating Purple Loosestrife with Look-a-likes.”

Sept. 24: Chris Litzau of Racine, Great Lakes Community Conservation Corps director.

Oct. 22: University of Wisconsin-Green Bay graduate students Cadie Olson and Brandon Falish will speak about “Green Bay: A Saga of Life, Destruction and Restoration.”

Nov. 12: Titus Seilheimer of Manitowoc, Wisconsin Sea Grant fisheries specialist, will offer “How to Eat Wisconsin Fish.” Seilheimer will talk about his favorite fish, the benefits of eating Wisconsin fish—both wild-caught and farmed—and how you can incorporate local fish into upcoming holiday celebrations.

Zoom will be used as the online event platform. Each event will last one hour and include time for Q&A after the presentation.

While web links and other technical details for the sessions are still being finalized, those interested can get more information when it is announced by following Wisconsin Sea Grant on social media (at the handle @UWiscSeaGrant on both Facebook and Twitter), or by going to the Wisconsin Sea Grant website at seagrant.wisc.edu (search for “Lake Talks”).

Training videos for fisheries managers cover techniques for sampling invasive carp species

On: August 18, 2020

In: AIS, aquatic invasive species, Asian carp, bighead carp, carp, silver carp, Tim Campbell

A series of online videos for fisheries managers who need to sample for invasive carp species like bighead and silver carp is now available. This unique resource—a collection of 17 videos that can be watched on YouTube—grew out of a workshop that took place in spring 2019 at Lake Barkley State Resort Park in Kentucky.

The partners behind the workshop and the resulting video series are the Mississippi River Basin Panel on Aquatic Nuisance Species (MRBP), Wisconsin Sea Grant, the U.S. Fish and Wildlife Service, the U.S. Geological Survey, and the Kentucky Department of Fish and Wildlife Resources. The videos can be found on Wisconsin Sea Grant’s YouTube channel.

The April 17-18, 2019 workshop on invasive carp species featured experts from around the country, who presented to about 65 attendees.

The MRBP funded the event, and Wisconsin Sea Grant Video Producer Bonnie Willison filmed on location in Kentucky to create the training videos, working in cooperation with Sea Grant Aquatic Invasive Species Outreach Specialist Tim Campbell. Campbell also serves as the Wisconsin representative on the MRBP.

Said Campbell, “This workshop was a one-of-a-kind interagency effort to train people in the methods needed to sample for bighead and silver carp.” Those methods can be different from standard ones familiar to most U.S. fisheries professionals. For example, different gear may be needed, and the video series covers different types of gear and how to use it, among other topics.

“I’m so glad that workshop organizers had the forethought to capture this event so this knowledge could be preserved and shared with more people,” added Campbell.

The effort as a whole is aimed at more effective management of these invasive species in the waters of the Mississippi River basin, a vast watershed covering about 40% of the continental U.S. The methods demonstrated at the workshop can be used for a combination of monitoring (to know where the fish are) and control (to remove the unwanted species).

Bighead and silver carp are problematic because they eat a lot, grow rapidly and become quite large, with silver carp exceeding 60 lbs. and bighead carp exceeding 100 lbs. If left unchecked, they become abundant and make recreational uses of lakes and rivers difficult due to their sheer numbers. They also pose a significant threat to the Great Lakes, where they are not yet established.

The training videos may be viewed on YouTube.

Questions may be directed to Campbell at 608-263-3259 or tim.campbell@wisc.edu.

UW-Milwaukee researchers enlist antibodies to understand spiny waterflea diet

On: July 29, 2020

In: AIS, aquatic invasive species, invasive species, John Berges, Spiny Waterflea

While New Zealand white rabbits do not normally spring to mind when you mention the fauna of Lake Michigan, a recently published paper in Limnology and Oceanography: Methods, a journal of the Association for the Science of Limnology and Oceanography, shows how this cotton-tailed creature plays a role in a newly validated method for assessing the lake’s food web, along with yielding surprising finds about the feeding habits of invasive spiny waterfleas.

Sea Grant-funded scientist John Berges, a University of Wisconsin-Milwaukee professor of biological sciences, and UW-M biology colleague Craig Sandren (now deceased), set about investigating the impact of invasive zooplankton on the big lake’s system. As they weighed and rejected three different research tools, Berges suggested an approach that he termed, “almost naively simple.”

He harkened back to the 1970s for a process first used terrestrially to calculate what’s eating insects and what kind of insects are being eaten. Berges said the technique had seen limited use in the marine environment but that “this is really the first time it’s been used systematically in fresh waters.”

Berges noted, “What we like about it as opposed to some of the DNA techniques is that it’s pretty quick. It’s cheap. You don’t need big deep DNA sequencing. Most labs will be able to use this.” Additionally, he said, scientists—such as the University of Windsor’s Aaron Fisk—who are using stable isotopes to map food webs can use this process to corroborate findings.

So far, there’s been references to fish and bugs. Just where do the rabbits come into the picture? Berges provided a detailed rundown of this “simple” process: “You take the likely prey (of a spiny waterflea) and…you grind it up. You basically homogenize it, make a soup of it. You take that soup and you inject it into an animal. We’re going to use a bunny rabbit here. That bunny rabbit’s immune system goes nuts, making a whole bunch of antibodies against the proteins that are in the putative prey organism. You have a huge array, a suite, of antibodies which now recognize the proteins that are in that item that potential prey item, that you injected into it.”

There is then a rabbit blood draw—after six to 12 weeks, during which time the immune response has built up. In the lab, Berges’ team then took the antibody (also known as immunoglobulin IgG) fraction of the blood, “which is real easy to do, and you have basically stuff, the immunoglobulins, which are going to stick very, very precisely to the proteins that were in that particular (prey) organism. So, you have a nice little marker.”

The next step, he said, is to determine if any of the markers from the rabbit blood overlap with the predator, which is the spiny waterflea. “You grind up the predator (the spiny waterflea) and you let the immunoglobulin bind to all the predator’s proteins. You remove them (the predator’s antibody) …What we’ve got left over now is things that are going to react only to the prey and not to the predator.”

Berges continued, “We found a whole bunch of the predators and checked them out for 12 different prey and some of them we didn’t find. None of the predators had them and we can be pretty clear that the predators aren’t eating them. And other prey, almost everybody had some of the prey in them. Now, we have a fairly clear picture of what the spiny waterflea is eating and a couple surprises came out.”

There were two surprises. First was evidence that the spiny waterflea was consuming the larvae of invasive Dreissenid mussels, commonly known as zebra mussels or quagga mussels. “That’s a neat story. We have one invasive species eating another invasive species. Well, that’s kinda cool. But we think about it a little more and it doesn’t make an awful lot of sense because we have this great big predator why is it grazing on these tiny little larvae,” Berges said.

The researchers continued with their reasoning and are now confident that it’s a case of what is known as hyperpredation—the spiny water flea ate something that itself first ate the larval Dressenid mussel.

The second surprise was a 180-degree turn in the category of size—not a tiny food source like the Dreissenid mussel larvae, but a large organism. Evidence of a type of zooplankton called Limnocalanus macrurus, or one of the “big dogs in the lake” as Berges put it, was found to have been consumed by the spiny waterflea. In this instance, Berges said they reasoned the spiny waterflea was eating the juvenile and larval forms of the large copepod.

In the end and with the help of a few New Zealand white rabbits as interim hosts for ground-up zooplankton prey, Berges said, “We have reasonable explanations for those two strange things that we found, and a technique that now we’ve proven out.”

Report evaluates effectiveness of watercraft inspectors’ AIS prevention actions

On: July 22, 2020

In: AIS, aquatic invasive species, CD3, Molly Bodde, Tim Campbell

A research project recently completed by Wisconsin Sea Grant found that there was no statistical difference between an experienced watercraft inspector removing aquatic plants and small-bodied invertebrates from a watercraft using hand removal or using a CD3 waterless watercraft cleaning system. There was also no difference related to cleaning treatment duration. Study results are available in a recently finalized Wisconsin Sea Grant report authored by Tim Campbell, Molly Bodde and Titus Seilheimer.

Experimental trials consisted of a researcher placing a known amount of Eurasian watermilfoil or a mixture of spiny water fleas and wetland plant seeds on a watercraft. Then the inspector used each cleaning treatment for 90 or 180 seconds. The researcher then collected the removed specimens and recovered the remaining specimens to determine the percentage of specimens removed for each trial.

The same inspector completed every trial—a trained Wisconsin Clean Boats, Clean Waters inspector with two summers of inspection experience. The inspector did not have any previous experience with the CD3 cleaning system.

A key finding from the study was that a trained, experienced inspector can be very effective removing plants and small-bodied organisms from watercraft, with the inspector removing between 93 to 99 percent of aquatic plants and 80 to 92 percent of small-bodied invertebrates with the treatments, with no statistical difference between the methods.

Compared to a previous, similar study that also used a trained inspector (but not a CD3 system for comparison), these new results show a slightly higher removal effectiveness. Future research should investigate the roles that training and experience have in the ability of inspectors and boaters to remove aquatic plants and small-bodied invertebrates from watercraft.

Introducing “Introduced,” Sea Grant’s newest podcast

On: May 20, 2020

In: AIS, aquatic invasive species, Bonnie Willison, podcasts, Sydney Widell

Once niche, podcasts have gone mainstream. According to figures cited in Forbes, 62 million Americans now listen to podcasts each week.

Sea Grant’s Yael Gen designed the cover art for the new podcast.

While Wisconsin Sea Grant and the University of Wisconsin Water Resources Institute have been involved in podcasting for years—from the current series Wisconsin Water News to older programs like Earthwatch Radio—there’s a new kid on the block: a podcast called “Introduced” that will be devoted to aquatic invasive species (AIS). Its tagline is “aquatic invaders and stories from our changing waters.”

“Introduced” is the brainchild of Sea Grant Video Producer Bonnie Willison and student employee Sydney Widell, a UW-Madison geography and geosciences major from Shorewood, Wis.

The series will span seven episodes, with one per week released beginning May 27. Listeners can find it on Apple Podcasts, Google Play, Spotify and on Sea Grant’s website.

While the simple name for the series conveys a bit of mystery, it also makes perfect sense. Said Willison, “As Sydney and I started learning more about invasive species, we noticed that there is a tendency for people to villainize these species. But we also noticed that humans are the ones introducing all these species to new environments. The title for our series puts the agency on people, which is something that we focus on in the podcast.”

Guests interviewed in the series include representatives from the Wisconsin Department of Natural Resources, U.S. Geological Survey, UW-Madison, the Fond du Lac Band of Lake Superior Chippewa, and a rescue organization focusing on exotic animals. Several Sea Grant staff also make appearances.

Topics are wide-ranging, from Asian carp to the trade in invasive species on the Internet. Because the AIS field is so rich, Willison anticipates doing a second season of the “Introduced” podcast. Stay tuned!
