Summary A total of 4450 tagged two and three years old salmon smolt were released into the River Drawa. Tagged salmon was caught mainly in central Baltic. Downstream migrating smolt were caught in lower Oder River till mid‐May, and in the Szczecin Firth till the first decade of June. After reaching the sea, the tagged salmon migrated northeastward. They remained most of all in the central Baltic and were mainly caught near Gotland. In autumn of the third year after the release salmon were present on the spawning grounds. The fish attained an average of 58.2 cm and 1892g after the first year of sea life, 78.0 cm and 5329g after the second year, and 98.5cm and 9100g after the third year. Most of the tagged Drawa salmon were caught by Danish (44.7%) and Swedish (25.9%) fishermen.
