Salmon and Eel Returns: How Friesland Restored Native Fish Populations
August 17, 2026 · Frisian News
Salmon and eels are returning to Friesland's rivers and Wadden Sea after nearly vanishing. Decades of work to remove barriers and improve water quality are slowly bringing these fish back to the region.
The sight of salmon swimming through Friesland's waters appears more often these days. These fish, called zalm in Dutch and Frisian, once were so abundant that they sustained the region. Today they are returning, thanks to decades of work to clean up rivers and remove the barriers that blocked their migration routes. The comeback is slow but steady.
Before industrialization, salmon and eels filled Friesland's waters. Fishermen caught them in abundance in rivers and canals around Ljouwert, Snits, and the Wadden Sea. Starting in the 1800s, people built dams and sluices to control flooding and power mills. These barriers cut off the paths salmon need to swim upstream and prevented eels from making their long journey across the Atlantic and back. Pollution from industry and agriculture made recovery even harder.
Restoring these fish means opening the waterways. Water authorities have installed fish passages and removed old barriers, giving salmon and eels a route through the landscape they once knew. Conservation groups work to improve water quality. Hatcheries raise young fish and release them into rivers to strengthen recovering populations. The Wadden Sea, once a nursery for countless young fish, now shows signs of healing.
For Frisians, this restoration means more than environmental recovery. These fish are part of the region's identity and history. Local fishing communities, water boards, and conservation groups have invested in this work because they know that bringing these fish back means honoring the water that defines Friesland. It is a way of saying that the region belongs to both people and nature.
Salmon and eels will not return overnight. But each year, more fish make the journey home. For anyone who knows Friesland or has roots there, this quiet recovery is a sign that the region is learning to live with its water in a better way.
