| Outline of Final Research Achievements |
In East China Sea, floating seaweed rafts are very important for fisheries because they serve as spawning substrates for fishes and a habitat for juvenile fishes. We conducted research cruises in every February and/or March of 2010 to 2012 for surveying distributions of floating seaweed rafts and sampling them. The floating seaweeds consisted of only Sargassum horneri. They were distributed on the continental shelf west of the Kuroshio front. We surveyed distribution of Sargassum horneri along the coasts of East China Sea and its adjacent waters with Chinese, Korean and Taiwanese researchers and analyzed genetic differences among their localities. We studied a food chain, phytal fauna and floating durations of floating seaweeds. Particle tracking experiments using a numerical model of surface currents suggests that floating Sargassum horneri originate from the Chinese coast in East China Sea. Bottom trawl surveys found seaweed debris on the sea bottom.
