ABSTRACT. About 727,000 fish were tagged in Poland in 2007. Almost all the tagged fish (94.7%) were adipose fin-clipped (sea trout, salmon); this was about 37% of the total number of stocked salmonid fish. Fin-clipped fish were released into the Pomeranian rivers of the Rega, Parsęta, Wieprza, Słupia, and Łeba. The number of fin-clipped sea trout and salmon increased 4.9 times in comparison with the previous year. More than 54,000 of fish were tagged with Carlin and floy-tags. The most numerously tagged fish species were as follows: sea trout (58.3%), salmon (31.2%), vimba (4.7%), rainbow trout (3.7%) and Atlantic sturgeon A. oxyrhynchus (2.2%). A few telemetry field studies were carried out on sea-trout, sturgeon, and whitefish.
