To examine the movement of adult ocellate puffer after spawning, tagging experiment was carried out at Wakasa Bay, Fukui Prefecture, Japan. Fifty tagged puffer were released at Wakasa Bay on May 12 in spawning season of 1993 and twenty puffer were recovered by the end of December 1995. Most recoveries were reported from the western Japan Sea from Toyama Bay to Tsushima island. Eight recovered puffer were caught in coastal area of Wakasa Bay within about one month after release. Then, areas of recovery shifted into west from Wakasa Bay, one puffer was caught offshore of Izumo city and four were from Hibiki-nada and off Kita-kyushu in the western of Japan Sea. In the next spawning season, three tagged puffer were recovered at coastal area of Wakasa Bay. The result indicates that adult puffer in Wakasa Bay move from coastal area of the bay after spawning and some of them return to coastal area of Wakasa Bay in next spawning season from the western Japan Sea from Toyama Bay to Tsushima island.
