A remarkable discovery has been made in the Drava River: an angler in Croatia recently caught a ship sturgeon (Acipenser nudiventris), a species long believed to be extinct in the Danube River Basin. Measuring 176 centimetres and weighing 35 kilograms, the fish was safely released back into the river after being identified by local authorities. The sighting is encouraging as it marks the first confirmed record of the species in many decades.

The ICPDR applauds the recent signing of the"goMURra" Declaration by Austrian Water Minister Norbert Totschnig and Slovenian Minister for Natural Resources Jože Novak.

Bucharest, Romania – Nine countries along the Danube River have joined forces to protect some of Europe’s most endangered species: the sturgeons. On 9–10 July, thirteen project partners and strategic allies – including national ministries, universities, NGOs and research bodies – gathered in Bucharest to launch “MonStur in the Danube,” a new cross-border effort to monitor and protect these ancient migratory fish.

Sturgeons, the most endangered group of species worldwide, are facing a perilous situation in Europe. These migratory species, which once freely swam from the Black Sea up to Germany, now find their ecological corridors severed by multiple barriers. Human interventions - such as hydropower, sediment extraction, navigation, river channelisation, by-catch and illegal fishing - are exerting severe pressure on habitats and populations, calling for immediate, coordinated actions.

Presenting the latest in hazard and risk assessments, the ICPDR Technical Report on Accidental Pollution Hazards provides an in-depth analysis of accidental pollution. It highlights updated inventories for Accident Hazard Sites (AHS) and Tailings Management Facilities (TMF), employing advanced methodologies like the Water Hazard Index and Tailings Risk Index. Focusing on the most hazardous sites, the report also offers key recommendations for sustainable pollution prevention

On 20th May 2022, the ICPDR along with other UN-based organizations, including CTBTO, IAEA, IOM, UNIDO, UNODA and UNODC, participated in this year’s “Long Night of Research” (“Lange Nacht der Forschung”) Austria’s biggest science event for the public.
