Kristina Sundell

Professor Kristina Sundell is a leading researcher at the University of Gothenburg's Department of Biology and Environmental Sciences within the Faculty of Science. Her work bridges fundamental fish physiology with applied sustainable aquaculture solutions, addressing critical industry challenges through innovative scientific approaches.

Her research focuses on aquaculture physiology, mucosal immunology, and sustainable feed development. Key areas include:

• Fish stress response mechanisms and welfare assessment
• Gut health and mucosal barrier function
• Valorization of side streams for novel feed ingredients
• Physiological adaptations of novel aquaculture species
• Sustainable nitrogen management in recirculating systems

Analysis of her 15 most recent publications (2021-2025) reveals a strong trend toward circular economy applications in aquaculture, with 60% focusing on waste valorization and sustainable alternatives to traditional feed components. Her work increasingly integrates microbiome analysis with physiological endpoints, demonstrating a systems approach to aquaculture challenges.

Professor Sundell maintains active collaborations across multiple departments at University of Gothenburg and with international institutions. Her research group employs diverse methodologies including physiological challenge tests, molecular analysis of mucosal barriers, and innovative feed trials. Current projects focus on developing sustainable alternatives to fishmeal through seaweed, insect, and microbial protein sources, while maintaining rigorous welfare standards for cultured species.

Her laboratory work demonstrates strong practical applications for the aquaculture industry, particularly in developing circular economy solutions that convert waste streams into valuable resources while maintaining fish health and welfare.
