漂浮的海藻作为许多动物的栖息地在近海水域扮演着重要的角色。2000年，首次报道了东海近海春季大量浮游海藻的分布情况。在中国东海的浮藻中捕获了黄尾七尾鱼的幼鱼。因此，有必要对东海浮游海藻的分布有一个较好的认识。在冬末到早春期间，详细的信息尤其重要，这与黄尾鱼的幼年期相对应。为此，在2010年和2011年冬末至早春期间，利用R/V Tansei-Maru在东海日本专属经济区进行了野外调查。我们通过GPS获得了船只的位置，并通过目测获得了船只到木筏的横向距离。距离采样法（Thomas等人）应用于估算漂浮海藻密度（筏数km−2）。在研究巡航期间，也使用渔网随机取样海藻筏。在东海，海藻筏主要分布在黑潮以西的大陆架上，特别是在26°N ~ 30°N之间的海域。收集到的海藻筏只有马尾藻（Sargassum horneri (Turner) C. Agardh）一种。综合考虑海流和霍氏藻的地理分布，推测这些浮游海藻起源于中国中南部沿海的自然河床。考虑到大约的旅行时间，我们认为黄尾鱼在旅行的早期就定居在漂浮斑块上，即靠近中国海岸。
Floating seaweeds play an important role as a habitat for many animals accompanying or attaching to them in offshore waters. It was in 2000 that the first report described abundant distributions of floating seaweeds in offshore waters in the East China Sea in spring. Young individuals of the yellowtail Seriola quinqueradiata are captured for aquaculture purposes from floating seaweeds in the East China Sea. Therefore, a sound understanding of the distributions of floating seaweeds in the East China Sea is needed. Detailed information is especially important during the late winter to early spring, which corresponds to the juvenile period of the yellowtail. Thus, field surveys using R/V Tansei-Maru were conducted in the Japanese Exclusive Economic Zone in the East China Sea from late winter to early spring in 2010 and 2011. We obtained positions of the vessel by GPS and transversal distances from the vessel to a raft by visual observation. Distance sampling method (Thomas et al.) was applied to estimation of floating seaweed densities (rafts km−2). Seaweed rafts were also randomly sampled using nets during the research cruises. In the East China Sea, seaweed rafts were distributed mainly on the continental shelf west of the Kuroshio, especially in waters between 26° N and 30° N. Collected rafts consisted of only one species, Sargassum horneri (Turner) C. Agardh. Taking into account surface currents and geographical distribution of S. horneri, it is estimated that these floating seaweeds originated from natural beds along the coast between mid and south China. Considering the approximate travel times, it is suggested that floating patches are colonized by yellowtails early on during their trips, i.e., close to the Chinese coast.
