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.

Extreme winter weather killed brown trout eggs – but the populations recovered quickly
How long does it take for a species to recover from a disaster? A study from the Swedish University of Agricultural Sciences (SLU) shows that trout populations can recover in just a few years after a winter when streams froze to the riverbed – even though an entire cohort was wiped out. -
A new European study paves the way for more reliable monitoring of crayfish and crayfish plague using eDNA
Crayfish plague and invasive species threaten freshwater crayfish across Europe. In a comprehensive study, researchers from 13 European countries show that eDNA can improve monitoring, but that the choice of method is crucial for how reliable the results are. -
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.

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.
