摘要

摘要: 自2007年以来，黄海海域已连续爆发大规模浒苔绿潮并造成了严重的经济损失。在苏北浅滩条斑紫菜养殖筏架上的定生浒苔被认为是漂浮绿潮藻的主要来源。然而，现阶段对筏架定生绿藻的种源基础并不清楚。因此，在本研究中，我们通过现场调查结合室内试验来揭示了筏架定生绿藻的繁殖体源。同时，为了对黄海大规模绿潮进行防控，我们对防止绿藻在紫菜养殖筏架的附着做了相关研究。结果表明，（1）包括浒苔、缘管浒苔、扁浒苔、曲浒苔以及盘苔这五种海藻的微观繁殖体共同存在于苏北浅滩海域的水体及沉积物中，而且在不同时期它们的比例变化明显。（2）经过去皮处理后的毛竹可明显抑制浒苔微观繁殖体的附着。通过本研究，我们明确分布于苏北浅滩海域的绿藻微观繁殖体是黄海大规模绿潮的种源基础。同时，我们为从源头防控黄海大规模绿潮的发生提供了一个可行的手段。

Abstract: Since 2007, large-scale green tides dominated by Ulva prolifera consecutively bloomed in the Yellow Sea and caused great economic losses. The fouling U. prolifera on the Pyropia yezoensis aquaculture rafts in the Subei Shoal was regarded as the major source of the floating biomass. However, it was still unclear about the seed source of fouling green macroalgae attached on the rafts. In this study, the field surveys and the indoor experiments were conducted to reveal the source of propagules of the fouling green macroalgae on the rafts and to study the anti-fouling material for P. yezoensis aquaculture rafts which could possibly be a feasible strategy to control the green tides in the Yellow Sea. The results showed that (1) micro-propagules of several green macroalgal species, including U. prolifera, U. linza, U. compressa, U. flexuosa, and Blidingia sp. coexisted in the waters and sediments in the Subei Shoal and their proportion remarkably changed over time; (2) the bamboo poles with peeling treatment could significantly reduce the amount of U. prolifera micro-propagules attached. This study confirmed that the micro-propagules distributed in the Subei Shoal area were the precursors of the green tides, and provided a feasible method to control the Yellow Sea large-scale green tides at the beginning.
