Environmental DNA Sampling

This summer, our colleagues from the University of Belgrade - Department of Biology and Freshwater Protection - Dr. Jelena Đorđević-Aleksić, Dr. Marija Smederevac-Lalić, Dr. Jovana Kostić, and Dr. Gorčin Cvijanović - used environmental DNA (eDNA) sampling to study endangered sturgeons in the Velika Morava, Drina, and Sava rivers.

By detecting traces of genetic material left by fish in these rivers, the team demonstrated the power of eDNA as a non-invasive, cutting-edge method for monitoring endangered species. This approach allows researchers to study sturgeons without disturbing their habitats, making it a game-changer for conservation efforts.

Why it matters: Sturgeons are among the most threatened fish globally. As part of the #MonSturintheDanube project, this research strengthens the transnational monitoring system for sturgeon recovery across the Danube Basin and contributes to the ICPDR’s Joint Danube Survey 5, the most comprehensive river monitoring effort worldwide.

A huge thank you to the team for their dedication to protecting our aquatic ecosystems!
