Our work
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.

Fiskbarometern: The status of Sweden’s fish and shellfish stocks
At Fiskbarometern, SLU presents the status and trends of fish and shellfish stocks in Swedish marine and freshwater environments. The assessments for 2025 are now complete. The situation is most concerning in the Baltic Proper, while perch in Lake Vänern are on the rise. -
Sustainable on paper, but not in the sea: new study examines fisheries in the Northeast Atlantic
Fishing pressure in the Northeast Atlantic has decreased and fish stocks are recovering. However, a new study shows that the reference level used in fisheries advice gives an overly optimistic assessment of stock status. We risk fishing too intensively before stocks reach a sustainable biomass. -
Where do the giant cod in the Åland Sea actually come from? New research provides more clues
A new study from SLU shows that the fast growing cod in the Åland Sea probably do not reproduce locally but instead depend on larvae transported there by ocean currents. At the same time, chemical analyses indicate that this stock component may be unique and possibly represent its own population.

Food web assessment approaches
The project uses ecosystem models and integrated analyses to understand long-term changes in the Baltic Sea marine environment. -
Waterways for Marine Diversity
The Marine Waterways project studies fish populations and key spawning sites in Åland’s diverse coastal habitats, while also mapping recreational fishing in collaboration with the local community. The aim is to contribute to long-term sustainable fish stocks. -
Restaurering av kustfiskbestånd
Although most Swedish fish species are considered viable, overexploitation has led to depleted populations. The project maps priority species and habitats, their current status, and the restoration measures needed.
