自2007年以来，黄海发生了由大型藻类石杉水华引发的年度“绿潮”的防治，引起了人们的广泛关注。越来越多的证据表明，江苏中国沿海条斑紫菜养殖排上的微繁殖体是这些绿潮的主要来源。在这项研究中，我们研究了一种有机硅防污涂料对防止FU附着和发芽的效果。竹子和尼龙绳上的增殖繁殖，已被用于竹筏上。黄瓜栽培。结果表明，含1.0wt.%苯甲酸钠(NAB)的硅胶(Sylgard 184)涂层可使粘附率降至-lt；5%，并完全抑制FU的生长。涂层表面有大量增殖小体。因此，在竹绳和尼龙绳上涂上含有NaB的有机硅是一种潜在的有效方法，可以控制FU的初始生物量积累。增殖。
Prevention of annual “green tides” caused by blooms of the green macroalgaUlva prolifera, which have occurred in the Yellow Sea since 2007, has received much attention. Increasing evidence indicates that micro-propagules on the rafts used forPorphyra yezoensisaquaculture along the coastline of Jiangsu Province in China, were the primary source of these green tides. In this study, we investigated the effectiveness of a silicone antifouling coating for preventing the adhesion and germination ofU. proliferamicro-propagules on bamboo and nylon ropes, which have been used in rafts forP. yezoensisaquaculture. Our results demonstrated that a coating of silicone (Sylgard 184) containing 1.0 wt.% sodium benzoate (NaB) could reduce the adhesion rate to <5% and completely inhibited the growth ofU. proliferapropagules on the coated surfaces. Coating bamboo and nylon ropes with NaB-incorporated silicone thus proved a potentially effective method for controlling the initial biomass accumulation ofU. prolifera.
