Wild salmon and trout are quite rare in Finland’s rivers and streams. Obstacles, dams and dredging have made many of our waterways unsuitable for migratory fish.

Fortunately, some of these waterways are being restored in the interests of the fish. At the same time, this restoration work is helping to revitalise the overall natural environment of our rivers and streams.

Longinoja is a fine example of a successful restoration project. Since 2001, the restoration work has helped endangered trout return to the stream.

Fish eggs overwinter in the gravel.

After about 3 years, the smolt turn silver and migrate to the sea.

”If only I could get back to my home gravel to spawn in!”
Trout swim upriver to spawn.
