Romania lost an important fishing region and nearly all its caviar-producing lakes with the cession of Bessarabia to the USSR in 1940. But the Black Sea, the Danube and its flood-lands, as well as other rivers, lakes, and ponds, are favorable to the development of the fishing industry, which expanded rapidly during the early 1970s. About 80% of the fish comes from the Danube flood-lands and delta and 20% from the Black Sea. In 2000, the total catch was 7,372 tons, as compared with 95,473 tons in 1991 and 16,000 in 1960.
