Download information about fish migration

FROM SEA TO SOURCE is the result of collaborations and partnerships with fisheries professionals all over the world, drawn together to provide a major new text on the theme of fish migration. The underlying concept is the increasingly recognised need for preservation but, more frequently, the restoration of free migration for all species of fish.

The MOSELLUM is one of many project described in the book.

The electronic version of the book can be downloaded for free as a low resolution PDF file.

Mosellum - information centre - fish pass Koblenz

Welcome to the new information centre Mosellum at the fish pass in Koblenz. Here you can take a journey of discovery through the Moselle’s biotope or you explore the tensions between economic and environmental interests on the Moselle. You can also find a lot of information about eels, salmon and other fish - and perhaps even see them through windows or you enjoy a bird’s eye view of the fish pass and learn about future prospects for the fish in the Moselle.

The Mosellum has four different exhibition areas: Shore, Ship, Underwater and Outlook (see below). All areas can be reached by elevator.





SHORE - Of slopes and dams

@ Eva-Maria Finsterbusch, LfU

The Moselle Valley has many faces. The SHORE-exhibition focuses on the region’s geology and history. If you follow the course of the Moselle, you will see how it changes from its spring in the Vosges Mountains to its mouth into the Rhine River in Koblenz.

The flora and fauna in and along the Moselle reflect the diversity of the region’s many habitats. The SHORE-exhibition illustrates these plants and animals, which include rare, common, indigenous, and invasive species. For more information, see the displays and the “Moselle Table.”

SHIP - Temporal changes to the Moselle

The Moselle has been used as a transport route for 2,000 years. It has gone through a long period of developments from the Neumagen wine ship of the Roman period to the large cargo vessels of modern times. Today, the river is dammed along a stretch of 394 kilometers – from Neuves-Maisons in France to where it meets the Rhine at Koblenz – and is used to generate renewable energy.

These developments have greatly changed the entire Moselle ecosystem. The SHIP-exhibition explores the tensions between economic and environmental interests, and presents some preliminary solutions to this multifaceted conflict.

UNDERWATER - Why do eels and salmon migrate in opposite directions?

@ Eva-Maria Finsterbusch, LfU

The UNDERWATER-exhibition focuses on fish and their habitats.

Many species of fish migrate between different habitats, some of which are quite far apart. To enable them to migrate up the Moselle despite man-made barriers such as dams, modern fish passes are being built – not only here but in other rivers as well. This helps fish keep their natural migratory routes, and also helps the Moselle to fulfill EU requirements for river basin management plans.

The UNDERWATER-exhibition explains two examples of long-distance migratory fish – eels and salmon – and looks at their complex and sometimes perplexing life cycles. Photos, texts, and videos examine everything from the eel larvae’s strange behaviour to the salmon’s sense of orientation. The Fish Species Display offers further information on other Moselle River fish. With a little luck, you might spot one or two of these fish “live” in the fish pass.

OUTLOOK - Prospects for migratory fish

The OUTLOOK-exhibition looks at current possibilities and future prospects for fish that migrate up and down the Moselle.

This exhibition area explains programs to help eels. It also includes an interesting “fish obstacle course,” which illustrates how hard it is for fish to pass the dams and locks and reach a good place to spawn.

So if you want to find out more about these programs to restore connectivity, just head up to the roof terrace and take a look at the Koblenz lock and dam or the fish pass – or simply enjoy the view of the Moselle.
