Salmon RAS Videos (2020-present) – A curated YouTube playlist from UWSP Northern Aquaculture Demonstration Facility featuring RAS-N and SAS2 project videos on RAS technology, Atlantic salmon production, research objectives, and other educational content.
Maryland Sea Grant (2025)– A teacher-friendly guide by A. Cohn et al. titled “Planning for an Aquaculture System in the Classroom,” that helps agricultural educators set up and run classroom aquaculture systems.
Journal of Visualized Experiments (2025)– A peer-reviewed lab method video by Robert Harrington et al. titled “Extraction and Detection of Geosmin and 2-Methylisoborneol in Water and Fish using High-Capacity Sorptive Extraction Probes and GC-MS,” showcases a fast, automated testing method that can detect off-flavor compounds in water and fish tissue before they’re strong enough for humans to taste or smell.
Journal of the World Aquaculture Society (2025)– An article submitted by Dr. John Davidson et al. titled “Comparing Off-flavor Trends in Freshwater Recirculating Aquaculture Systems with Microbially Mature or Immature Biofilters while Growing Atlantic salmon Salmo salar,” compares newly started versus well-established RAS, finding that mature systems with more stable water chemistry produce far less off-flavor buildup in Atlantic salmon.
Aquaculture (2025)– An article submitted by Dr. Erin Legacki et al. titled “Modeling Embryo Survival: Genetic and Environmental Influences on Eye-up Rate in a North American Atlantic salmon Selective Breeding Program,” finds that warmer water and higher ammonia/nitrite levels lower fish egg survival, while maternal genetics don’t play a role.

Water Research (2024)– An article submitted by Dr. Raz Ben-Asher et al. titled “A New Approach for Eliminating Off-flavors from RAS fish, as Part of the Normal Grow-out Period,” explores a water treatment method that clears off-flavor compounds from farmed water, successfully removing them from rainbow trout within 11 days.
Isaac Wu’s Master Thesis (2024) – A thesis submitted to Virginia Polytechnic Institute and State University titled “Willingness-to-Pay for R.A.S. Salmon by U.S. Consumers,” examining consumer attitudes towards sustainably farmed fish.
Aquaculture (2023)– An article submitted by Dr. Erin Legacki et al. titled “Using Skin Mucus for the Identification of Ovulation Biomarkers in North American Atlantic salmon (Salmo salar),” examines the benefits and future of RAS in sustainable fish farming.
Journal of Ocean Technology (2023)– An article submitted by Dr. Yonathan Zohar titled “Innovative Aquaculture Technologies – Recirculating Aquaculture Systems,” examines how salmon hormones change around ovulation and shows that fish mucus can be used to measure those hormones.
World Aquaculture Magazine (2022) – Submitted by Fischer et al., “Midwest Facility is a Successful Model for Research, Demonstration, and Education for Freshwater Aquaculture” showcases UWSP’s Northern Aquaculture Demonstration Facility’s pivotal role in advancing sustainable fish farming practices.
Salmon RAS Concept Paper (2022) – An industry-informed deliverable from RAS-N titled “Advancing Atlantic Salmon Recirculating Aquaculture Systems in the US: Challenges, Opportunities, and Strategic Recommendations,” synthesizing stakeholder input to guide the development of sustainable land-based salmon farming.
RAS-N One-pager (2021) – A visually engaging, single-page flier designed for Congressional outreach, highlighting the RAS-N project’s role in advancing U.S. land-based salmon aquaculture.
Stakeholder Priorities for Salmon RAS (2021) – A summary of barriers and areas of need for land-based commercial production reported to RAS-N by industry stakeholders.
Aquaculture Magazine (2021): – An article submitted by Drs. Catherine Frederick and Yonathan Zohar titled, “Bringing experts together from around the globe to expand sustainable land-based US production of Atlantic salmon.”
