Department of Aquatic Resources

At the Department of Aquatic Resources (SLU Aqua) we conduct research on fish and shellfish in seas, lakes, and watercourses. We monitor the aquatic environment and develop methods and expertise for the sustainable use of aquatic resources.

  • Our vision: Viable fish stocks in healthy waters
Our work
A group of people in waders are electrofishing in a small stream surrounded by lush forest. A man in waders and a cap holds a net and an electrofishing rod while talking to the others, who are holding a black bucket and other equipment. The environment is natural and humid, with rocks and branches in the water

Education

We offer training and courses for those interested in fish and fishing, marine biology, limnology, and aquatic ecology.

Research

We conduct research on aquatic ecosystems, fish, fishing, and fisheries management.

Environmental monitoring and assessment

How is the fish population along our coasts and in our seas, lakes, and watercourses doing? We track changes, explain them and show the way forward.

    Healthy cod in the Åland Sea carry a chemical mystery

    Researchers at the Swedish University of Agricultural Sciences (SLU) have made a remarkable discovery in cod from the Åland Sea. Compared to their relatives in the rest of the Baltic Sea, the Åland cod have extremely high levels of boron in their otoliths. But where it comes from remains a mystery.
