E-DNA has been used, for example, to track the spread of the coronavirus in our wastewater. But now researchers from the Swedish University of Agricultural Sciences are testing whether it can be used to track pike. In a controlled environment in Hemmesta Sjöäng, outside Värmdö in Stockholm, we meet Göran Sundblad who tells us more about the project. He also hopes that the study will attract more attention than SVT’s moose migration.
