1) During the cold season from December of 1965 to may of 1966, the authors observed the phenomenon of fish stranding on the beach of Shingu, northern Kyushu. In this paper the collections of over 10, 000 specimens of 135 fishes were treated under some considerations. 2) The maximum numbers of both species and specimens were reached in January, and their number decreased with the change of the season. The dominant species were Cololabis saira and Engraulis japonica in December, Sebastes sp. and Bregmaceros spp. in January, Maurolicus japonicus in February, and Ammodytes personatus in March and April. 3) Excepting for the abruptly appeared species, there was no evident year to year variation of stranding fishes in the two years. The phenomena may be one of the important causalities of the natural mortality for the infant in our waters. The authors with to acknowledge the kind assistance of Messrs. S. Kimura, Y. Nonogami and T. Shima of Fisheries Laboratory, Kyushu University. The observations wouldnt be performed satisfactorily without their help, valuable information and encouragement.
