By tagging fish and shellfish, you get information about migration patterns and growth, survival, distribution and stock size. The Department of Aquatic Resources (SLU Aqua) tags fish in several research projects. SLU Aqua also administrate tagging projects on behalf of universities and county boards. On this webpage you can report if you caught tagged fish or shellfish. You can also read about ongoing research projects .

The Fish Tagging Database

The fish tagging database at the Department of Aquatic Resources collects and stores some of Sweden's national data on release and recapture of tagged fish in freshwater. It currently contains over 80,000 recapture registrations and approximately 8,000 release series. Data is available from the 1940s.

The fish tagging database is quality assured according to SLU's quality assurance plan: to provide open data in accordance with the ambitions of the joint authority strategy for environmental data management.

Data can be disclosed upon request for an administrative fee.
