This section will promote relevant recent hydrobiological studies. It will be great to see more and more of these reports for any major and minor European water body.

Herewith, a link to a recent report about the Huchen population in the Danube basin.

Conservation Genetics study of Huchen in Slovenia.

[EXCERPTS]
