Research Abstract

In East China Sea, drifting seaweeds play an important role as nursery ground for juveniles of yellowtail and Japanese mackerel. However, there had been little information about drifting seaweeds. Therefore we studied distribution, ecology and source of drifting seaweeds in East China Sea. Our studies clarified that drifting seaweeds consisted of only Sargassum horneri, rafts of drifting seaweeds were distributed shoreward from the Kuroshio front and Sargassum forests around the islands off Zhejiang Province, China, consisting of mainly S. horneri were a possible source of drifting seaweeds.
