Aquatic Observatory

A fish pass has been built into the riverbed, allowing visitors to observe salmon and fish migrating up the Aulne through large picture windows. A digital system makes this site, the only one of its kind in Finistère, a fish-counting station of regional importance for the discovery of migratory fish in their natural environment.

The aquatic observatory is a place to observe salmon and other fish migrating up the Aulne, thanks to large picture windows installed when a fish pass was created in the riverbed.
The system is complemented by a digital fish-counting system unique in Finistère. This regionally important observatory enhances studies on fish migration in their natural environment.
