    Sturgeons in the Danube Basin

    Sturgeons are sensitive to environmental pressures and therefore valuable indicators for healthy rivers. This is why the ICPDR has endorsed sturgeons as flagship species. There are six species of sturgeons native in the Danube River Basin, but the survival of these ancient fish is threatened by a range of issues. Through the "Danube Sturgeon Task Force", the ICPDR contributes to actions such as the protection of habitats, the development of migration aids, the breeding of healthy stocks in sheltered facilities, or the struggle against illegal fishing and caviar trade.

    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.

    daNUbs - Nutrient Management in the Danube River Basin

    daNUbs was a mulitnational EU research project carried out under the leadership of the Technical University of Vienna. The results from this project include estimates of nutrient inputs into the river network (MONERIS), as well as an assessment of the loads of nitrogen, phosphorus and silica transported via the river network. These results indicate that the nutrient status in the Black Sea has significantly improved since the 1980s.

    Nutrients

    The nutrient levels, notably phosphorus and nitrogen, found in the Danube River and its major tributaries hold significant international importance. This is because they directly contribute to the phenomenon of eutrophication in both the river itself and the Black Sea. Historical trend analysis of nutrient river loads over the past decades shows a significant reduction in the transported nutrient fluxes to the Black Sea. Overall nutrient emissions declined by 30% (nitrogen) and 50% (phosphorus) in the last 15 years. However, the current long-term fluxes are still considerably higher than those of the early 1960ies which represent river loads under low pressures, indicating a further load reduction potential that might be exploited for the benefit of the Black Sea. Nevertheless, in the last 5-10 years the measured loads are rather low and close to the Black Sea targets indicating significant water quality improvement.
