Distribution and spawning activity of the Danube salmon (Hucho hucho) in the Upper Drina River

This study examines the endangered Danube salmon, or huchen, which is unique to the Danube River basin and faces severe threats, particularly in the Balkans, once the species' last stronghold. However, even in the Balkan rivers, the huchen has now lost much of its distribution area. With the remaining huchen habitat largely restricted to Balkan rivers like the Drina and Tara, this study focuses on determining the current population status and identifying breeding grounds in the upper Drina basin. Major threats include pollution, hydropower development, and overfishing, yet restoration opportunities are possible with targeted conservation efforts.
