The importance of the Elbe as a habitat for different fish species was a central theme during an eventful boat trip of the federal government, which recently took place in the port of Lenzen. As part of this event, Sanne van Sonsbeck headed the new boat, the Smüster Elw, with a fully occupied group of 15 guests as well as members of the federal government and the nature guard. The boat trips not only have an informative character, but also strengthen the awareness of the visitors for domestic nature.

The dangers for local fish species

Christian Wolter, research group leader at the Leibnitz Institute for water ecology and internal fishing, gave an revealing lecture on the fragile ecosystem of the Elbe. A questionable aspect is the almost complete extinction of two types of fish: the mayific and the sturgeon. This situation raises questions about the developments and challenges with which the ecosystem is confronted.

The role of the grans and invasive species

During the lecture, Wolter emphasized the role of groybs that were constructed in the 19th century, and their importance for different fish species. The Schwarzmeer-Grundel in particular has settled here. This invasive type uses the stone caves of the groyne as a resort and plays an important role in the ecosystem because they feed mussels like the three -cant mussel, which in turn contribute to water cleaning.

Challenges for sturgeon and salmon

Another critical point is shown by the hunt for interference that is caught for caviar production. Despite a general ban on catch, all types of interference are threatened with extinction. Wolter explained that the salmon, which should also spawn in the Elbe, often have to fight with a lack of oxygen when they swim to their spawning sites. These challenges illustrate the difficulties that these species have in a changing ecosystem.

Ecological Education

The response of the participants was consistently positive. Sven and Simone Schnakenbeck expressed how valuable the information found, especially for hobby anglers. The discussion about the productivity and the condition of the rivers is particularly relevant in the present day, given the challenges of climate change and environmental changes. The event underlines the importance of ecological education and the commitment of citizens for the protection of natural resources.

Such boat trips not only offer a possibility for clarification, but also a platform for the exchange of ideas and the establishment of a sense of community among the participants, which is of crucial importance for the joint preservation and protection of the Elbe.
