RAS in Action Thumbnail

RAS in Action

Aquaculture Systems Highlight

Tyler Firkus, UWSP NADF Operations & Research Programs Manager, walks us through the facility’s recirculating aquaculture systems (RAS), raising Atlantic salmon and walleye. Learn the basics on the steps of a RAS as well as the critical equipment needed.
Fish Health Dissection Thumbnail internal anatomy.

Fish Dissection Overview

Best Managment Practices for Fish Health

UWSP NADF created two videos as part of a fish health workshop organized by the Great Lakes Aquaculture Collaborative. The videos explain how to external and internally examine fish for fish health practices. The dissections are led by veterinarian, Dr. Myron Kebus, who walks us through various observations regarding fish anatomy to determine overall health. Walleye and Arctic char were utilized, raised in indoor RAS systems at UWSP NADF.

Market Research for Raising Atlantic Salmon in RAS

UWSP NADF Project Film Series

Willingness to pay by the consumer is a critical piece of information when determining business planning. For example, understanding what consumers are willing to pay for Atlantic salmon and how willingness may differ based on attributes of the fish such as the rearing system utilized, or feeds provided. This video showcases research being done to explore consumer willingness to pay for Atlantic salmon raised in water reuse systems. This is one of 17 research objectives as part of Sustainable Aquaculture Systems: Supporting Atlantic Salmon, funded by USDA National Institute of Food and Agriculture.

Research to Produce Reproductively Sterile Atlantic Salmon

UWSP NADF Project Film Series

Learn how and why researchers are looking to create reproductively sterile Atlantic salmon to support the food fish industry. This is one of 17 research objectives as part of Sustainable Aquaculture Systems: Supporting Atlantic Salmon, funded by USDA National Institute of Food and Agriculture.

Investigating Larval Feeds for Walleye

UWSP NADF Project Film Series

Larval rearing of walleye is the most challenging aspects in culturing this species. This video explains research done at UWSP NADF to identify larval feed options for growth and survival of hybrid walleye, known as the saugeye.

New Aquaculture Guide Helps Fish Farmers Raise Walleye for Commercial Production

University of Wisconsin Sea Grant Institute

According to lead author and aquaculture outreach specialist Emma Hauser, the guide is the culmination of years of research and a great enthusiasm for the fish, especially in the upper Midwest where it’s enjoyed both as a game fish and one that’s good to eat.

The Consequences of Sea Lamprey Parasitism on Lake Trout Energy Budgets

Conservation Physiology

Research done at UWSP NADF provides a plausible explanation of the energetic mechanisms that lead to skipped spawning following sea lamprey parasitism and could be used in population models to explore sublethal impacts of sea lamprey parasitism and other stressors on population dynamics.

Diet Influences Survival and Growth of Intensively Reared Larval Saugeye

Aquaculture, Fish and Fisheries

Research done to investigate various commercially available larval diets for raising hybrid walleye (saugeye) intensively indoors. The diets were evaluated based on growth and survival of this species at the larval stage. Currently, there is no larval diet formulated for walleye, therefore evaluating currently available diets is important for industry growth.

Effects of Formaldehyde (Parasite-S®) on Biofilter Nitrification From a Cold and a Warm Freshwater RAS

Aquaculture Research

To maintain proper husbandry conditions in aquaculture, an occasional use of chemical disinfectants or chemotherapeutants may be required, such as Formaldehyde, which is currently approved for use in flow-through systems. However, in a recirculating system, chemical application risks impairing communities of nitrifying bacteria in the biofilters resulting in potential ammonia or nitrite accumulation. UWSP NADF and partners investigated how formaldehyde impacts a RAS in terms of water quality and biofilter function.

Cisco Aquaculture Best Practices: Randomized Experiments from Eggs to Juvenile

North American Journal of Aquaculture

Further information on rearing and restocking of the ecologically important, Lake Herring species is needed, especially toward understanding the biological culture needs of eggs, larvae, and fingerlings. To address this gap in the literature and to provide essential fish culture information, UWSP NADF performed three preliminary studies in 2010.

Northern Demonstration Facility Prepares Students for In-demand Aquaculture Careers

UWSP Communications & Marketing

UW-Stevens Point was the first university in Wisconsin to offer an aquaculture minor and the first accredited university in the nation to offer full semester aquaponic courses. Sustainable aquaculture meets consumer demand for seafood while taking pressure off wild populations and enhancing food security, safety and quality, notes Chris Hartleb, biology professor, who launched the program.
