On Saturday, Helsingborg's first sea allotment was inaugurated, where blue mussels are grown in so-called mussel socks. The hope is that the mussels will be able to eat and that they will not contain environmental toxins from the water.

But there are more purposes with the project, says Annelie Eckeskog, project manager and marine biologist at the City of Helsingborg.

"One idea of the project is that it will make people interested in what happens underwater. In the long run, it can contribute to the oceans being better taken care of," she says.

Mussel farming can also contribute to greater biodiversity in the port area, says the project manager.

Needs to be cleared as an allotment on land

The sea allotment in Helsingborg is special in the sense that there is no similar project in Sweden where residents in the community can get involved and help. In other parts of the country, it is more controlled by researchers, says Anneli Eckeskog.

The project manager describes that just like an allotment on land, where weeds need to be cleared from time to time, the mussel socks also need to be cleared.

Camilla Ljungerud is one of the 70 who have chosen to get involved. Together they keep the mussel socks in good condition and make sure that they do not disappear.

"When I started, I didn't know anyone," says Camilla Ljungerud, who thinks it has become a great sense of community among the volunteers.
