Anne Johanne Tang Dalsgaard

Anne Johanne Tang Dalsgaard is a Senior Researcher at the National Institute of Aquatic Resources (DTU Aqua), Technical University of Denmark, specializing in sustainable aquaculture practices. Her work focuses on reducing environmental impacts through feed optimization and waste management solutions for fish farming operations.

Her educational qualifications include:

• Ph.D. in Fatty acid trophic markers as measures of energy transfer through marine food webs exemplified by sandeel, University of Copenhagen (1999-2003)
• M.Sc. in Resource Management and Environmental studies, University of British Columbia (1996-1999)
• B.Sc. in Biology, University of Copenhagen (1992-1995)

Dr. Dalsgaard's research centers on nutrient dynamics in aquaculture systems, with expertise in feed formulation, waste excretion characterization, and end-of-pipe treatment technologies. She develops practical tools like aquawaste.dk for waste estimation and investigates recirculating aquaculture systems (RAS) with emphasis on phosphorus management and sustainable feed ingredients. Her work directly contributes to UN Sustainable Development Goals 12 (Responsible Consumption) and 14 (Life Below Water).

Analysis of her 2024-2025 publications reveals a concentrated research trajectory toward minimizing phosphorus discharge through dietary interventions and advanced water treatment. Current studies examine chitin supplementation, carbon-to-nitrogen ratios, and alternative protein sources like horse beans, all targeting improved environmental performance without compromising fish health.

She actively supervises two PhD candidates on amino acid optimization and microalgae feed projects while leading major initiatives including OPTIFOS (enzyme dosing for phosphorus reduction) and Værdikæde (circular economy in aquaculture value chains), demonstrating significant grant acquisition capabilities in Danish aquaculture research.

As a core member of DTU Aqua's Section for Aquaculture, she collaborates extensively with industry partners and international researchers to advance recirculating aquaculture systems and develop practical solutions for sustainable fish farming.
