| Abstract: | Kyungsang-Namdo Fisheries Experimental Station released 620 drift bottles in the west strait of the Tsushima Strait from 1932 to 1939. Among them 183 were recovered. Fukuoka Prefectural Fisheries Experimental Station also released 1930 bottles in the east strait between 1954 and 1969. Recovered bottles were 442.The bottles drifted to the south in winter owing to a northwesterly wind, and drifted to the northeast in spring and summer with the Tsushima warm current. Bottles released at the west strait drifted to the north along the east shore of Korea, went around the Ullung Island, and then to the northeast. Drift bottles released at the east strait drifted to the north along the shore of Japan and washed ashore on the coast. |
