Join ARK Rewilding Nederland on World Migratory Fish Day for a walk along the longest most flowing side channel in the Netherlands. Are you curious which migratory fish occur in the Netherlands and would you like to discover for yourself which fish use the side channel? Then sign up for this excursion!

Twelve species of migratory fish originally lived in the Dutch great rivers. From the small stickleback to the giants of the river: the sturgeon. During the spawning period, fish use the river and streams to migrate upstream or downstream. The sturgeon is one of the species that spends its adult life at sea, but uses the river to spawn. Unfortunately, this impressive fish became extinct in the Waal/Rhine River seventy years ago. Now several organizations are jointly investigating whether reintroduction is possible. By removing dams and opening the locks between river and sea more often, we are preparing our river nature for the return of the species.
Migratory fish do not respect national borders, therefore we are also working together with German organizations for a healthy Rhine in the program The Rhine connects.

The Netherlands has worked hard on its rivers in recent years. There were several reasons for this, such as water safety, water transport and nature restoration. With the construction of side channels, more water flows through the floodplains. Good news for migratory fish and other marine life. Trees have also been submerged in the new channels at several locations. The insertion of river wood creates different environments and gradients in the water. During our walk we will see how nature has responded to this.

At the end of the field trip for World Fish Migration Day, a “seine” will be pulled together with RAVON (organization for reptiles, amphibians and fish). This is a large net that drags across the bottom. The captured fish can be viewed in a cuvette. Then we give them back their freedom! At the end of the excursion, the RAVON tour leader will tell some more about the research on eels and knack eels.

Start time 13.00
