欧洲的海藻养殖正在增长，并可能提供环境效益，包括栖息地供应，海岸保护和生物修复。海藻养殖场提供的栖息地在很大程度上仍然是不可量化的，以前的研究主要集中在表生生物的有害影响，而不是他们在生态功能和生态系统服务提供的作用。我们在英国西南部康沃尔郡的一个农场监测了栽培糖海带（Saccharina latissima）表生体群落的发育和多样性，并比较了不同收获技术对表生体群落结构的影响。在生长季节和生长季节之后，在养殖海带上发现了表生体丰度（PERMANOVA，F4，25 = 100.56，p < 0.001）和多样性（PERMANOVA，F4，25 = 27.25，p < 0.001）的增加，到夏末（8月），达到平均丰度>6000个个体/海带植物，分类丰富度约为9门/海带。甲壳类动物（主要是端足类动物）、软体动物（主要是双壳类动物）和苔藓虫占主导地位，它们发挥着重要的生态作用，尽管降低了作物质量。部分收获技术保持，或增加，epibiont丰度和多样性超出了农业季节，但是，这些海带植物显着犯规，并不会在大多数市场上的商业可行性。本文提高了对欧洲海带养殖场表生体组合发展的理解，这可以为可持续的，基于生态系统的水产养殖方法提供信息。
Seaweed farming in Europe is growing and may provide environmental benefits, including habitat provisioning, coastal protection, and bioremediation. Habitat provisioning by seaweed farms remains largely unquantified, with previous research focused primarily on the detrimental effects of epibionts, rather than their roles in ecological functioning and ecosystem service provision. We monitored the development and diversity of epibiont assemblages on cultivated sugar kelp (Saccharina latissima) at a farm in Cornwall, southwest UK, and compared the effects of different harvesting techniques on epibiont assemblage structure. Increases in epibiont abundance (PERMANOVA, F4,25 = 100.56, p < 0.001) and diversity (PERMANOVA, F4,25 = 27.25, p < 0.001) were found on cultivated kelps over and beyond the growing season, reaching an average abundance of >6000 individuals per kelp plant with a taxonomic richness of ~9 phyla per kelp by late summer (August). Assemblages were dominated by crustaceans (mainly amphipods), molluscs (principally bivalves) and bryozoans, which provide important ecological roles, despite reducing crop quality. Partial harvesting techniques maintained, or increased, epibiont abundance and diversity beyond the farming season; however, these kelp plants were significantly fouled and would not be commercially viable in most markets. This paper improves understanding of epibiont assemblage development at European kelp farms, which can inform sustainable, ecosystem-based approaches to aquaculture.
