Sargassum horneri C. Agardh is an important commercial edible seaweed species in east Asia. Benthic beds and floating rafts in coastal areas make excellent habitats for marine organisms to feed, hide, and spawn. Many commercially important fish species such as Japanese anchovy (Engraulis japonicus), yellowtail (Seriola quinqueradiata), and Japanese horse mackerel (Trachurus japonicus) live in seaweed beds. Chinese and Japanese fisherman rely on S. horneri beds as productive fish harvest areas. The Zhejiang government in China set a total allowable catch standard, to preserve the Ma'an Islands ecosystem, which is a marine protected area. In this study we analysed the association between weight and one-sided surface area of S. horneri beds, and calculated the ratio of one-sided surface area to change in wet weight over time. We collected samples from December 2014 to May 2015. Approximately 1 g of S. horneri biomass provided ~15 cm2 of one-sided surface area available to marine organisms. These calculations can be used as a reference regarding potential space to improve total allowable catch standard management in S. horneri beds, through the estimation of space capacity of seaweed beds.
沙菜是东亚地区一种重要的商业食用海藻。沿海地区的底栖床和漂浮筏为海洋生物提供了极好的觅食、藏身和繁殖场所。许多商业上重要的鱼类，如日本沙丁鱼（Engraulis japonicus）、黄尾鱼（Seriola quinqueradiata）和日本马鲛鱼（Trachurus japonicus），都生活在海藻床中。中国和日本的渔民依赖沙菜床作为高产的鱼类捕捞区。中国浙江省政府为了保护马安岛生态系统（一个海洋保护区），设定了总可捕量标准。在这项研究中，我们分析了沙菜床重量和单面表面积之间的关系，并计算了单面表面积相对于湿重随时间变化的比值。我们于 2014 年 12 月至 2015 年 5 月采集了样本。大约 1 克沙菜生物量提供了约 15 平方厘米的单面表面积供海洋生物使用。这些计算可作为参考，用于通过估计海藻床的空间容量，改进沙菜床的总可捕量标准管理。
