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.

The presence of grey seals affects the chance of catching pike
Using recreational fishing and mark–recapture methods, researchers estimated how many pike live in a Baltic archipelago bay—2,449 individuals. When grey seals appeared, catches fell sharply, not because pike disappeared, but because their catchability declined. -
Current target for sustainable fishing involves unnecessarily high risks
A new study shows that the level currently used as a benchmark for maximum sustainable yield carries a higher risk of stock collapse than previously assumed. Almost the same long-term catches can be achieved with slightly lower fishing pressure, but with a significantly lower risk to the stocks. -
SLU’s Fisheries Research Station in Älvkarleby has now closed for good
After more than 100 years of operation, Sweden’s first facility for compensatory fish farming of salmon and trout has now permanently closed its doors.

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.
