During the cold seasons of 1965-1967, the authors observed the fish-stranding phenomenon at the beaches from Kagoshima to Niigata Prefecture along the Tsushima Current. The following results were obtained : 1) The stranding animals were recognized in the whole area of the present research, and the phenomenon was more prominent in the northern Kyushu and westernmost Honshu in the cold months of 1966. The stranding animals in Karatsu and Shingu beaches of northern Kyushu were quite similar in species and specimen composition. 2) The authors admitted the stranding animals as the following groups: the southern migrants, the coastal fishes, the offshore fish larvae, the offshore benthic crustaceans and the southern pelagic crustaceans. 3) In respect of their appearance range, these animals could be classified into two groups. The one was recognized in almost whole area, and the other appeared only in the stations in the west of westernmost Honshu area. This area coincided with the demarcation line of ichthyofauna.
