The fish wetland has been created by damming the stream that runs between Laduviken and Husarviken on Norra Djurgården in Stockholm.

It has created a wetland on Lillsjöängen which has become a play area for pike and perch.

- Hopefully we will be able to continue this together with the landowner Kungliga Djurgårdsförvaltningen to see if there are more and more pike that come up, says Oliver Karlöf.

We went pike hunting when the wetland was emptied last week.

See how it went in the clip above.
