The saithe, Pollachius virens (L.) is a marine fish, rep-resenting the family Gadidae. It naturally occurs in the North Atlantic Ocean and it has been rarely reported from the Baltic Sea (Froese and Pauly 2008). The hitherto con-ducted parasitic surveys of this fish focused on the Atlantic, particularly the Sea of Norway and the Barents Sea (e.g., Rokicki and Strömberg 1991, Karasev et al. 1996, Strømnes and Andersen 1998, Lom 2002). The Baltic Sea is a brackish inland body of water with salinities ranging from 3.7 PSU (Bothnian Bay) to 8 PSU (Pomeranian Bay) (Łomniewski et al. 1975).
