Multiple antifouling strategies of marine organisms may consist of combinations of physical, chemical and mechanical mechanisms. In this study, the role of surface microtopography (< 500 microns) of different marine organisms, such as Cancer pagurus, Mytilus edulis, Ophiura texturata and the eggcase of Scyliorhinus canicula, has been investigated as a possible component of their defence systems. High resolution resin replicates of these natural surface structures were exposed to natural fouling in field experiments. Abundances of recruits were determined and compared to those on untextured, but otherwise identical, control surfaces to quantify the influence of the different microtopographies on fouling rates. Antifouling effects of microtopographies varied with type of microtopography and coloniser species. The surface microtopography of C. pagurus significantly rejected macrofoulers. The surface structures of the eggcase and O. texturata had repellent effects on microfoulers. Barnacle settlement was temporarily reduced on surface microtopographies of M. edulis and the eggcase. These results emphasise the promising nontoxic antifouling properties of microtextured surfaces.
海洋生物的多种防污策略可能由物理、化学和机械机制组合而成。在本研究中，已对不同海洋生物（如黄道蟹、紫贻贝、细纹蛇尾和港海豹的卵壳）的表面微观形貌（<500微米）作为其防御系统可能组成部分的作用进行了研究。在野外实验中，将这些天然表面结构的高分辨率树脂复制品暴露于自然污损环境中。测定新附着生物的数量，并与无纹理但其他方面相同的对照表面上的数量进行比较，以量化不同微观形貌对污损率的影响。微观形貌的防污效果因微观形貌类型和定殖物种而异。黄道蟹的表面微观形貌显著排斥大型污损生物。卵壳和细纹蛇尾的表面结构对小型污损生物具有驱避作用。在紫贻贝和卵壳的表面微观形貌上，藤壶的附着暂时减少。这些结果强调了微纹理表面具有前景广阔的无毒防污特性。
