| Abstract: |
| To discover the distribution of green algal micro-propagules in the Subei Shoal and clarify the growth of green macroalgae attached on Pyropia aquaculture rafts, an integrated investigation in Pyropia aquaculture area and one cruise in the coastal area of the Subei Shoal were carried out from March to May in 2013. The results showed that green algal micro-propagules were discovered in seawater and sediment during March to May. The average quantity of micro-propagules was 267 ind./L in surface seawater and 43 ind./g in sediment. The biomass of attached green macroalgae increased in Pyropia aquaculture from March to May. Three species, including Ulva prolifera, Ulva linza and Blidingia sp. were found in Pyropia aquaculture rafts. The dominant specie was Blidingia sp. and the second was U. prolifera in spring. This study indicated that the micro-propagules and macroalgae were existed in the coastal area of the Subei Shoal at the early stage of green tide. This was the key point to the governance of green tide in China. |

| 为了揭示苏北浅滩紫菜养殖区附着绿藻和绿藻微观繁殖体的分布现状,从2013年三月到五月份对苏北浅滩紫菜养殖区及附近海域进行航次调查。结果表明, 绿藻微观繁殖体在水体和沉积物中广泛分布,水体中的平均值为267株/L,沉积物中的平均值为43株/g。调查期间,紫菜养殖区筏架上附着绿藻的生物量持续增长。在紫菜筏架上发现有浒苔,缘管浒苔,盒管藻三种绿藻,其优势种为盒管藻,其次是浒苔。研究表明,绿潮发生早期在苏北浅滩海域存在绿藻微观繁殖体和附着绿藻,这将为中国绿潮治理提供理论支撑。 |
