Observatoire aquatique

The Observatoire aquatique is a visitor center with large windows surrounding a viewing room that allows year-round observation of fish in the Aulne River. The space offers a direct view into the water world and shows the variety of local fish species in their natural setting.

The center was founded to study the migration patterns of Atlantic salmon, shad, and lamprey in the Aulne River. These fish pass through the river on their seasonal journeys, which explains why this location became important for understanding their life cycles.

Scientists and researchers gather at this location to collect data on fish populations, contributing to the understanding of regional aquatic ecosystems.

The facility is accessible on weekdays with varying hours depending on the season, with longer opening times during summer months. Visitors should check which times work for their visit before traveling.

The center uses video camera systems to measure fish length and record identifying marks. This enables researchers to track individual specimens precisely and document their movements.
