| 摘 要： | 通过室内实验研究了海月水母(Aurelia sp.1)浮浪幼虫在活体牡蛎、牡蛎壳、扇贝壳、波纹板、网衣(200μm)、PV管等材料上的附着选择性和水螅体在竹竿和水泥块上的增殖问题。实验表明,浮浪幼虫对人工材料(波纹板、网衣、PV管)具有偏好性,附着密度较大;水平放置的附着材料底部附着更多的水螅体。水螅体可以通过无性繁殖方式在新的栖息地形成水螅体种群,种群扩张过程中存在密度限制,较低密度时水螅体种群增长较快,高密度时水螅体种群增长较慢。作者认为,日益增加的海洋废弃物(塑料、玻璃、木材),以及海底构造物(海水养殖筏、海洋工程)为水螅体提供了更多的附着表面,这有利于水螅体栖息地的扩张,形成更大的水螅体种群。 |

| Abstract: | During ocean exploitation habitat for polyps might increase, thus increase jellyfish polyps populations, and then enhance jellyfish population. In this study, we examined planula of Aurelia sp.1 settlement on living-oyster, oyster shell, scallop shell, floor plates, netting and PV-pipe, proliferation of polyps on the surfaces of bamboo and cement block. The planula and polyps preferred man-made materials(floor plates,netting and PV-pipe). The underside of floor plates was strongly favorable for settlement. Polyps can form new polyps population through asexual reproduction on new habitat, the expanding process was limited by polyps population density. When the density was relatively low, polyps population increased rapidly, and this increase was slower when density was relatively high. Increasing litter (plastics,glassand wood) pollution and submarine constructions (maricultureand ocean engineering) providemore attachment surfaceand thus enlarge the areas of polyps distributionand form larger number of polyps populations. |
