蓝鳍海葵的水华经常发生在沿海沃茨。由于沿海地区人工结构的扩大，珊瑚虫的定居和增殖所需的基质越来越多，这被认为是水母大量繁殖的一个可能的促成因素。本文研究了海洋人工湖（凤凰湖）是否为A.蓝水母是水母繁殖的温床。高密度的A.结果表明，该湖有蓝球藻，平均密度为41只/m3，最大密度为128只/m3。与此同时，A.在湖外的两条排水沟中也发现了蓝球藻，平均密度为13只/m3。水下调查显示，A.根据线粒体COI基因序列的系统发育分析，蓝囊珊瑚主要分布在多毛类动物形成的生物礁上，该多毛类动物被鉴定为一种入侵的蛇类动物Hydroidesdianthus。我们的研究强调了外来多毛类对栖息地的潜在改变。石竹科底栖动物可能提供了复杂的底栖生态环境，适宜于A.这可能会导致海洋人工湖和附近沿海沃茨的水母大量繁殖。
Blooms of the moon jellyfishAurelia coeruleafrequently occur in coastal waters. The increased availability of substrates for the settlement and proliferation of polyps due to the expansion of artificial structures in coastal areas has been proposed as a possible contributing factor in jellyfish blooms. This paper investigates whether a marine artificial lake (Fenghuang Lake) provides additional substrates forA. coeruleapolyps and contributes to jellyfish blooms. High densities ofA. coeruleaephyrae were discovered in this lake, with a mean density of 41 individuals/m3and a maximum measured density of 128 individuals/m3. Meanwhile,A. coeruleaephyrae were also found in the two emptying channels outside the lake, with a mean density of 13 individuals/m3. Underwater surveys revealed that dense colonies ofA. coeruleapolyps occurred mainly on biogenic reefs formed by a polychaete, which was identified as an invasive serpulid speciesHydroidesdianthus, based on the phylogenetic analysis of mitochondrial COI gene sequences. Our study highlights the potential modification of habitats by the alien polychaeteH. dianthus, which might provide complex benthic habits suitable for the settlement and proliferation ofA. coeruleapolyps and may contribute to jellyfish blooms in the marine artificial lake and nearby coastal waters.
