Danube
The Danube was once a long-standing frontier of the Roman Empire, and today flows through 10 countries, more than any other river in the world. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The Danube river basin is home to fish species such as pike, zander, huchen, Wels catfish, burbot and tench. It is also home to a large diversity of carp and sturgeon, as well as salmon and trout. A few species of euryhaline fish, such as European seabass, mullet, and eel, inhabit the Danube delta and the lower portion of the river.
Danube River Conference of 1948
The Danube River Conference of 1948 was held in Belgrade, Yugoslavia, to develop a new international regime for the development and control of the Danube in the wake of World War II. It was the first postwar conference pitting the victorious Allies of the west against the Soviet Union and its allied states of Eastern Europe in which the latter held a majority and were expected to win all points of disagreement between the two sides. As such, it attracted more than the usual share of attention from East and West alike.
