A stream in a pipeline
Yes! Back to my home stream to spawn! – I’m going to the sea to enjoy an adventure and grow big! – I think I’ll stay right where I am!
In this section of the stream, a road for people crosses a road for fish. The Longinoja stream passes through a pipeline for a distance of 200 metres under the Kehä I ring road. In other words, there are trout swimming beneath the busiest road in Finland!
The trout feed in the sea for a couple of years before returning to spawn in their home stream.
The fish swim through the pipeline to get to the spawning gravel upstream.
