In this paper the writers deal with the method and technique for providing a more accurate representation of the body size composition of Jomon shell-midden fish. The specimens analysed here are Acanthopagrus schlegeli (black sea bream) obtained during 1971's excavation of Kamitakatsu shell-midden, Ibaragi Pref. The size frequency distribution of black sea bream premaxillary from the same units, but one derived from laboratory analysis of core samples and another recovered in the trench, were compared (Fig. 2 and Table 1) and, in the former, there occurred a considerable amount of small size specimens of black sea bream which had been missed in the trench. The result shows that the application of core sampling and wet-screening technique furnishes more reliable data on the representation of the body size composition in any prehistoric fishes.
