在不断增加的海洋建筑上建立新的栖息地可能会增加水母息肉的数量，从而增加世界各地的水母数量。在这项调查中，我们调查了1821年唇形水蚤在六种常见的码头建筑材料上的浮游率和浮游息肉迁移率。在人造表面上选择栖息地时，扁平和水生动物更喜欢塑料(发泡聚苯乙烯、低密度和高密度聚乙烯)，而不是橡胶和处理过的木材。基板表面纹理和防污染化学品的存在/不存在是造成这些基板偏好的可能原因。这项研究阐明了不同人造结构对水母种群的潜在影响，并为沿海管理人员和港口当局减少生物污染和水母水华影响提供了有用的信息。
New habitat on proliferating marine construction may increase jellyfish polyp populations, and thereby increase jellyfish populations worldwide. In this investigation, we examined planula settlement and polyp immigration rates of the scyphozoan Aurelia labiata Chamisso & Eysenhardt, 1821 on six common dock-building materials. The planulae and polyps preferred plastics (expanded polystyrenes, low and high density polyethylene) to rubber and treated wood when choosing habitat on man-made surfaces. Substrate surface texture and the presence/absence of anti-fouling chemicals are discussed as possible causes for these substrate preferences. This study illustrates the potential effects of different man-made structures on jellyfish populations, and provides useful information to coastal managers and port authorities for reduction of biofouling and jellyfish bloom effects.
