Abstract
41502 tagged rainbow trout were released into the Baltic Sea, mainly to the Gulf of Gdańsk, and to some Polish rivers, mainly to the River Vistula. 2504 returns from “older” fishes and 1486 from “younger” fish made it possible to determine distribution and migrations of the released fishe. Rainbow trout migrated all over the Baltic Sea, but most were caught in the Gulf of Gdańsk and in coastal Polish waters. They were also fairly abundant in Danish Straits, and single specimens were caught in the North Sea and Norwegian Sea. The fish tended to migrate westward. This trend was more pronounced in the fishes released at Jastarnia. Site of release and fish age affected the distribution and migrations of rainbow trout.
