"Wisconsin Aquaculture Conference Connects Producers, Researchers and Others to Enhance the Industry" - WI Sea Grant Article

World Aquaculture Conference: Percid Session
The Triennial WAS is the largest aquaculture conference in the world, hosting over 4,000 attendees from over 90 countries. UWSP NADF co-chaired a Percids Session with Alan Johnson (IA DNR) at the conference located in New Orleans, March 2019. The presentations specific to walleye production have been uploaded for viewing.

Overcoming Barriers in Atlantic Salmon Production Underway
UWSP NADF and partners at The Conservation Fund's Freshwater Institute are currently performing research to establish effective therapeutic strategies to combat saprolegniasis (also known as fungus) a current issue for Atlantic salmon production facilities, effecting the vulnerable stages of fingerlings at pre and post smoltification. The research is helping to discover effective dosage levels of Peracetic Acid (PAA) and Hydrogen Peroxide to only reduce losses due to saprolegniasis but also maintain adequate water quality and performance for fish raising in recirculating aquaculture systems. 
Wisconsin Sea Grant has featured this project inside the Aquatic Sciences Chronicle. The article features details of the project and the strong partnerships involved including The Conservation Fund's Freshwater Institute,  and private companies Superior Fresh (Wisconsin) and Riverence (Washington).

Sea Lamprey Wound Classification Workshop Arises from Previous Project...
For the past three years, research at UWSP NADF is determining the sub-lethal effects of sea lamprey parasitism on both lean and siscowet lake trout broodstock, identifying effects on fecundity, growth, and immune response. Project collaborators included Michigan State University, Michigan DNR, NOAA and funded by the Great Lakes Fishery Commission.
As the wounds healed, it became difficult to classify what type the original wound was without referring back to the data. Since this project has the unique ability to track the progression of healing wounds and knowing the original wound classification, it provides opportunity for understanding misclassification rates and improving the use of lamprey wound data. Tyler Firkus, doctoral candidate of MSU and PI on this project is offering a wound classification workshop in May to allow experts in the field to assess lamprey wounds on live fish and compare their classifications to the known wound type that was classified immediately after the parasitism event.

"This workshop gives attendees the opportunity to gain experience by classifying wounds on live lake trout, watching  wound assessment demonstrations, and seeing where classification errors and undetected wounds are happening based on their own scoring data," Firkus states (in photo at left).  "Attendees will also be able to see how the wounds they are assessing have healed over time as we have taken weekly pictures of some of the wounded fish.  In some cases, we have documented wounds that do not heal as expected under the current classification system.  Additionally, the workshop will allow us to discuss strategies for improving wound classification consistency and data quality," he added.

Walleye & Saugeye Eggs at UWSP NADF
Eggs currently incubating at UWSP NADF will be utilized for both extensive and intensive production of Walleye and Saugeye in 2019.
  • Saugeye will be raised intensively in UWSP NADF larval system as part of a Sea Grant funded project to optimize larval rearing densities utilizing the best larval feeds discovered in Year 1 of the project. UWSP NADF has reconstructed one of the two larval systems at the facility, now able to operate and raise walleye, saugeye or sauger in forty three, sixty-gallon fiberglass larval rearing tanks for research and demonstration.
Stay Tuned...
UWSP NADF has submitted for publication the standard operating procedures, designs and management of the walleye larval rearing system. Notification on release of the publication will be through the UWSP NADF Newsletter, social networking sites and UWSP NADF website...

2,000 + Walleye Donated to Local Community...
UWSP NADF recently donated over 200lbs of walleye and saugeye fillets to the Red Cliff Tribal Elderly Nutrition Program with the help of the community. UWSP NADF also donated over 2,000 walleye and saugeye to the surrounding communities for food fish.
The walleye and saugeye were part of strain evaluation, raised in a water reuse system on commercial feed. The fish were nearly one year, and averaging over one pound. The fish were purged in cold, fresh water before harvest to provide a clean, firm fillet.

"We have only heard great reports on how well the fish tasted and elders want to thank UWSP NADF for all the fantastic fish they received"- Mark Duffy, Chief Conservation Warden for the Red Cliff Band of Lake Superior Chippewa Indians, who assisted UWSP NADF to harvest the fish and distribute to the community.

WI Consumer Survey on Farm Raised Fish provides Insight for Aquaculture farmers...

To better understand what people in the state think about Wisconsin aquaculture, researchers from the UW-Madison, UW-Stevens Point, UW-River Falls and UW-Milwaukee conducted a statewide survey, funded by University of Wisconsin Sea Grant Institute. One of the main purposes of the survey was to determine if Wisconsin consumers prefer fish that's grown in the state, in the U.S. or imported, as well as their preferences for wild-caught versus farm-raised fish. Check out the results...

Before the school year ends, this spring nearly 150 students ages K-12 will have visited UWSP NADF for an interactive tour (above photos). Groups this spring include students from school districts of Hurley, Ashland, Bayfield, Washburn, and Lac Courte Oreilles. Educational tours at UWSP NADF are an important outreach and education effort to support sustainable aquaculture as well as promote aquaculture as a STEM teaching tool and potential career choice.
UWSP NADF strong partnership with Wisconsin Sea Grant supports various aquaculture research, educational and development projects at the facility.

Currently WISG is funding the development and advancement of new species for Wisconsin aquaculture, including two Walleye and Saugeye projects, and one Nationally funded Atlantic salmon project. Check out these and more in WI Sea Grant's Biennial Report...

Aquaculture Events  
  • 2019 RAS Tech Conference: RAStech (formerly the ICRA Conference in Roanoke, VA), May 13-14th in Washington, DC is a technical conference and tradeshow serving the emerging recirculating aquaculture systems (RAS) sector. A land-based, low impact aquaculture process, RAS has the potential to meet the world’s growing need for protein with minimal effect on the environment. RAStech gathers producers, researchers, policy makers and suppliers in the RAS space. Learn More...
