Enigmatic fish: European sturgeon discovered in the chalk lake!

Kreidesee, Niedersachsen, Deutschland - In Lower Saxony, a remarkable find was made: an almost extinct fish was spotted in the chalk lake, a popular diving area - the European sturgeon. This body of water is not only known for its beauty, but also houses the deepest mailbox in Germany. A viral video that was divided on social media shows the liveliness of the Kreideesee and the presence of this special fish.

European sturgeon is considered extremely rare in Germany and is classified as almost extinct. Historically, the sturgeon was widespread in large rivers such as the Elbe, the Rhine and the Oder. According to the Federal Office for Nature Conservation , about 80 percent of the 27 types of interference are endangered or threatened with extinction. Intensive fishing, caviar use and water pollution have led to a drastic decline in stocks. The last natural inventory in Germany disappeared from the Eider in 1969.

challenges of resettlement

Nowadays, only occasionally disturbances are trapped in the mouths of the North and Baltic Sea, mostly only as outlier or exposed animals. In order to counter the decline, there have been projects for resettlement of the interference in Germany since the 2000s, supported by federal and state authorities as well as nature conservation organizations. The bfn has been promoting research and breeding projects for the type, with partners such as the Leibniz Institute for Water Ecology and Inland Fishing (IGB) as well as the society for rescue the sturgeon (grS) are integrated. The main goal is to build up a parent's resistance to resettlement.

A special problem with resettlement is the long life span of the interference. These fish only reach sexual maturity after 12 to 16 years and become over 100 years old. In Germany, the parenting population in Germany currently comprises more than 400 animals between 6 and 13 years. Further measures to improve the chances of survival of the sturgeons are planned, including the transfer to new keeping facilities and the addition by offspring.

cooperation between nature conservation and water management

The resettlement of the European interference is part of a broader nature conservation political framework. The preservation of biological diversity and water development require close cooperation between nature conservation and water management. According to the Environmental Office , renaturation measures such as the development of habitats are critical of the preservation of water-dependent species. Restremes of the water and the creation of habitats are urgently necessary to secure the natural functionality of water and their banks.

A large part of the German Bach and Flow Mows is now designated as a Natura 2000 area. These areas are of crucial importance for the preservation and restoration of sensitive habitats and types. The task of nature conservation and water management is not only in the protection of valuable species, but also in ensuring a sustainable handling of water resources.

The existence of the European interference in the chalk lake is a positive sign that shows that the biodiversity can be restored and protected by targeted efforts and projects.
