A total of 138 yellowtail (Seriola quinqueradiata) with archival tags were released in the Tsushima Warm Current from January 1999 to February 2002. Geographical positions were estimated using archived data from 26 fish recaptured at age of 4 years and over. The results showed three migration patterns from 4 years on, as migrants, between the East China Sea and west coast of Hokkaido, migrants, between the East China Sea and the Noto Peninsula, or San-in district and residents around the Noto Peninsula for more than a year. Previously, only the first migration pattern was reported. The spawners of yellowtail that migrated from Japan Sea to East China Sea was estimated to spawn in the shelf edge zone of East China Sea and south of Kyushu.

Key words: adult yellowtail, archival tag, migration, spawning ground
