Sargassum Vegetation Growing in the Sea around Tsuyazaki, North Kyushu, Japan

Abstract

Ecological studies on the subtidal marine vegetation, including the Sargassum community, have not progressed far because it is harder to make field surveys in subtidal vegetation than in terrestrial or intertidal vegetations. Some depth records for species of marine algae have been obtained using dredges and other instruments. From these data, we know that there is considerable vegetation developed at subtidal depths (cf Ueda and Okada, 1938, 1940).
