| Abstract: |
| Green tides caused by the unusual accumulation of high floating Ulva prolifera have occurred regularly in the Yellow Sea since 2007. The primary source of the Yellow Sea green tides is the attached algae on the Pyropia aquaculture rafts in the Subei Shoal. Ulva prolifera and Blidingia (Italic) sp. are the main species observed on Pyropia aquaculture rafts in the Subei Shoal. We found that U. prolifera has strong buoyancy and a rapid growth rate, which may explain why it is the dominant species of green tides that occur in the China's sea area of the Yellow Sea. The growth rate of floating U. prolifera was about 20%–31% d–1, which was much higher than Blidingia (Italic) sp. There were about 1.7×104 t of attached algae on the Pyropia aquaculture rafts in May 2012. We found that 39% of attached algae could float when the tide rose in the Subei Shoal, and U. prolifera accounted for 63% of the floating algae. Our analysis estimated that about 4 000 t of attached U. prolifera floated into the surrounding waters of the Subei Shoal during the recycling period of aquaculture rafts. These results suggest that the initial floating biomass of large-scale green tides in the Yellow Sea is determined by the U. prolifera biomass attached to Pyropia aquaculture rafts, further impacting the scale of the green tide. |

| 绿潮主要有大量的漂浮浒苔聚集而成，自2007年以来，黄海绿潮连年爆发，来源于苏北浅滩紫菜养殖筏架上的定生绿藻。浒苔和盘苔是养殖筏架上主要的绿藻种。我们发现浒苔具有强大的漂浮和生长能力，使其成为大规模黄海绿潮的优势种。漂浮浒苔每天的生长率高于盘苔可以达到20-31%。2012年5月，紫菜养殖筏架上大约有1.7×104 t 定生绿藻，大约39%的定生绿藻可以漂浮，漂浮绿藻中浒苔占据了63%。我们评估在苏北浅滩海域大约4000t的定生浒苔进入海洋成为漂浮浒苔。我们的结果显示紫菜养殖筏架上定生浒苔的生物量决定入海漂浮浒苔的起始量，进而决定了黄海绿潮的规模。 |
