The Atlantic sturgeon, Acipenser oxyrinchus oxyrinchus Mitchill, has been considered to be an extinct species in the Baltic Sea for many years. Polish program to restore it to the Vistula basin was initiated in 2006 using cultured fish. This paper presents data regarding the distribution of juvenile Atlantic sturgeon released into the Drweca and Wisloka rivers (Vistula drainage). Tag returns from juvenile Atlantic sturgeon were few at just 3.15 percentage for fish released into the Drweca and 0.85 percentage for those released into the Wisloka. Information obtained from stocking the Drweca River was used to analyze the distribution and growth of juvenile Atlantic sturgeon. These fish were caught most frequently in the Gdansk Bay and the mouth of the Vistula River (Poland)
