Welcome to the electrofishing database. Here you can download data from more than 70,000 electrofishing surveys, distributed over approximately 20,000 sites. You can also find information about how to conduct environmental monitoring using electrofishing as a method. The database for electrofishing in streams (SERS) is the Swedish national database for electrofishing data and has been in use since 1989. All data is publicly available.

Data used in research, lists of threatened species and ecological status

The database for electrofishing in streams (SERS) is officially called the Swedish Electrofishing Register (SERS).

Data is used in national evaluations, for example, in assessing the ecological status of Sweden’s watercourses, but also in monitoring fisheries conservation measures (e.g. liming, construction of bypasses for fish, biotope restoration). Data is also used in research projects and in national compilations, such as the Red List of Threatened Species by SLU Swedish Species Information Centre.

SLU data hosting

The Department of Aquatic Resources are data hosts for data on fish on behalf of the Swedish Agency for Marine and Water Management. We deliver quality-assured data from test fishing within national and regional environmental monitoring and liming programs. With our efforts, the outside world gets faster access to the latest results. Information about data hosting is also available on the Swedish Agency for Marine and Water Management's website.
