Northern Aquaculture Demonstration Facility 

Recirculating Aquaculture Salmon- Network (RAS-N). Project partners have recently created a website to help share project initiatives, current research, news and more on salmon raised in land based systems. Check it out at
The website is part of a nationally funded project to Build Capacity of  Sustainable Production of Atlantic Salmon in Land Based Systems and assisting to meet the overarching goal of the project, which is to build capacity and establish a holistic hub of knowledge that will integrate past, current and future research as well as outreach, education and extension to promote the successful growth, stability and economic feasibility of the Atlantic salmon RAS sector and, more broadly, US aquaculture. 

The Great Lakes Aquaculture Day 2020! 

This was the first of its kind virtual conference that featured a variety of panel discussions and presentations on aquaculture throughout 7 Great Lake Sea Grant states. Held on October 10th, various presentations and panel discussions were provided that targeted a variety of audiences, from beginning and current farmers to consumers interested in learning more about preparing and cooking seafood. The event was hosted by the Sea Grant Great Lakes Aquaculture Collaborative, a project of Sea Grant programs across the region—including Wisconsin Sea Grant—that are working to share resources and promote best practices in the aquaculture industry. 

Recordings of the event  are available topics,  posted on the Great Lakes Aquaculture Website.
Meet Sam Patula, UWSP NADF Aquaculture Technician

"I received my bachelors of science in zoology with two minors in chemistry and environmental studies at Southern Illinois University Carbondale. After my undergraduate, I continued at SIUC where I received my Masters of Science in zoology. The focus of my Masters thesis was sustainable aquaculture by means of replacing fishmeal in fish feeds with soybean meal as a protein source, while also implementing a nutritional programming feeding regime. I also studied the effect soybean meal and nutritional programming on the fish gut microbiome in different life stages of zebrafish and largemouth bass larvae. While at SIUC I also worked on several other species including walleye, yellow perch, and tilapia. I am looking forward to expand my knowledge in aquaculture specifically in salmonids and other innovative aquaculture species." - Sam Patula

As Aquaculture Technician, Sam is assisting with the facility's research and demonstration projects, rearing both cool and cold water species at various life stages including walleye, Atlantic salmon, lake trout and Arctic char. This also includes gaining experience in various culture systems; ponds, raceways, recirculating, incubation and larval systems.

Assessing the assumptions of classification agreement, accuracy, and predictable healing time of sea lamprey wounds on lake trout.  

As part of the research done at UWSP NADF on sub lethal effects of sea lamprey wounds on lake trout with Michigan State Doctoral candidate Tyler Firkus, a workshop was also conducted where experienced professionals examined lake trout with known sea lamprey wounds.
Sea lamprey control in the Laurentian Great Lakes relies on records of sea lamprey wounds on lake trout to assess whether control efforts are supporting fisheries management targets. Wounding records have been maintained for 70 years under the assumption that they are a reliable and accurate reflection of sea lamprey damage inflicted on fish populations. However, two key assumptions underpinning the use of these data need thorough evaluation: sea lamprey wounds follow a predictable healing progression, and individuals classify wounds accurately and reliably. To assess these assumptions, we conducted a workshop where experienced professionals examined lake trout with known sea lamprey wounds...  Full publication can be accessed in the Journal of Great Lakes Research.. 
Wisconsin Public Radio Features Wisconsin Aquaculture!
Dr. Chris Hartleb, UWSP NADF Director and Brandon Gottsacker, President of the world's largest aquaponics facility, Superior Fresh discuss aquaculture in Wisconsin with host Kate Kent on WPR. Brandon and Chris discuss the impact of COVID on aquaculture businesses but also the local impact and sustainability of Wisconsin farms as well as global perspective of the industry, while answering questions from the audience. Listen to the conversation on WPR.


Eat Wisconsin Fish helping Wisconsin Farmers Reach Consumers
Sharon Moen has been hired by Wisconsin Sea Grant as an Outreach Specialist for the Eat Wisconsin Fish initiative, which provides consumers, grocers, chefs and others with fact-based information via a website, social media, events and trainings. Currently she is updating food-fish farmer information, which will be incorporated into three mapping tools to help potential customers buy products offered by Wisconsin's fish farmers.

“The Eat Wisconsin Fish initiative provides opportunities for all fish growers to develop skills, advance technologies and find audiences for their products. I would value your input on how Eat Wisconsin Fish and Wisconsin Sea Grant could best help food-fish aquaculture succeed in Wisconsin.” -Sharon Moen

Aquaculture farmers are encouraged to reach out to Sharon at or 218-624-5735.

Eat Wisconsin Fish Internship Opportunity!
This opportunity will support the EWF program with culinary and/or illustration skills. The internship includes creation of cooking techniques and recipe videos that focus on fish harvested or produced in Wisconsin.  This internship will also assist in telling the story of Wisconsin food-fish by illustrating fish, aquatic food webs, farm-to-table concepts, and the health-related aspects of eating fish. This work will become part of the Eat Wisconsin Fish website, social media and more. Check it out!

Renew Your Membership to WAA!
A message from the Wisconsin Aquaculture Association
"Why join WAA?  In the past few years, we have been able to get the Aquaculture Bill passed.  This not only benefits members who actively pursue aquaculture activities but also all pond owners who help manage our aquatic resources. It is the intent of the WAA to provide you training and informative articles in The Creel.  If you have ever toured an active fish farm and left with only a fraction of your questions answered, you owe it to yourself to become a member and take advantage of the information provided in The Creel, our training sessions, and the camaraderie of the WAA Aquaculture Conference".
- Bill West, WAA President

COVID 19 National Impact Survey- QUARTER 4

Please participate in the Virginia Tech and The Ohio State University organized Quarter 4 (2020) national survey of the effects of the 2020 pandemic on your aquaculture farm or business covering the period from October 1, 2020 to December 31, 2020. Results from this study may be used to communicate the effects of coronavirus disease (COVID-19) on commercial aquaculture, aquaponics or allied businesses to State and Federal agencies, in an effort to secure relief. 

Even if you have not been negatively affected, the pandemic economic impacts are needed to effectively report what is happening to US aquaculture. Survey deadline is January 22nd, 2021.
