Salmon: (almost) ready to make a comeback in Switzerland
Insurmountable obstacles
Salmon are migrating fish. After growing to maturity in rivers and streams they set off for the ocean – a journey that often covers thousands of kilometres. Ultimately when it's time to spawn they return to where they originated from, and the cycle begins again.
There is a reason why they make this arduous journey. While the conditions in the oxygen-rich waters of Switzerland such as the rivers Rhine, Aare and Limmat are good for young salmon to mature in, the adult fish meet their food requirements by hunting large swarms of krill found in the ocean.
The journey can only be made along a living, healthy and obstacle-free river. The migration of salmon along the Rhine came to an abrupt end in the first half of the last century, as rivers were channelled, hydroelectric power plants were built, and water quality deteriorated. These are all factors that negatively impact and prevent the natural movements of salmon and other migrating fish.
Thankfully, humans have learned from their mistakes and started to correct some of them in recent years. But there is still work to be done before the salmon can return to Switzerland and feel comfortable in our waters. WWF has bundled the necessary measures together in its “Salmon Come Back” project.
What your community coins can achieve
The work that WWF is doing to help salmon return to Switzerland includes the following measures, which your donations will help to fund.
- Making rivers passable: Salmon should be able to migrate up the Rhine to their birthplace in Switzerland, and also swim downstream to the sea. Currently there are still three hydroelectric power plants in Alsace that need to install fish passes, and in Switzerland there are also a number of power plants in need of renovation.
- Improving the habitat: Lost habitats have to be restored. Salmon need gravel banks to deposit their eggs, and as young fish they require a variety of habitats. These can be recreated by means of restoration projects.
- Generating interest: The salmon is a symbol of the work we are doing, and encourages people's interest in having bodies of water that are full of life and variety. It helps us draw attention to existing problems, and all work together to find solutions. Everyone should be able to play a part in this.
