A recommendation paper by the ICPDR, developed for the ongoing revision of the EU Urban Wastewater Treatment Directive (UWWTD). Bulgaria bans sturgeon fishing
Sofia, 1 May 2011. In order to protect endangered sturgeon species, Bulgaria decided to ban sturgeon fishing in May 2011. Romania was the first country to implement a sturgeon fishing ban in the Danube in 2006 and is now followed by its southern neighbour.
Organic Matter
Organic pollution has been on the rise in the Danube over the last century, as human activities have resulted in increasing loads of wastewater rich in organic matter. The most serious organic pollution problems occur in tributaries that regularly receive untreated or inadequately treated wastewater from industrial plants and municipalities. Thanks to the significant improvement of wastewater infrastructure and services in the Danube countries, the basin-wide organic emissions reduced by 60% since the mid 2000s.
Invasive Alien Species
The Danube River is seeing an influx of new non-native species, stemming from the increasing interconnections with various European and global water bodies via canals and other waterways designed to facilitate navigation. It is currently believed that alien species are very likely to become even more significant in the future, as the importance of the Danube as an international waterway increases.
