We profiled and compared the bacterial and protist community compositions and dynamics in the Laoshan Bay marine ranching involving varied aquaculture activities. The dominant species, differential species and community compositions among the five aquaculture areas, two habitats and two periods were significantly different. The relationships between microbial communities and environmental factors were analyzed. We found that microbial communities in the water were more sensitive to the environmental changes than sediment, and the responses of bacterial and protist communities to the disturbances were varied. To meet the challenges of higher aquaculture density, the proportion of the positive correlations among co-occurrence networks in the water increased markedly from July to November; while the positive proportion in the sediment was stable. Potential ecological interactions and keystone taxa between bacteria and protists were studied. These results advanced our understanding of how mariculture stressors affect microbial communities in marine ranching.
我们对涉及不同养殖活动的崂山湾海洋牧场的细菌和原生动物群落组成和动态进行了分析和比较。五个养殖区、两个生境和两个时期的优势种、差异种和群落组成有显著差异。分析了微生物群落与环境因素之间的关系。我们发现，水中的微生物群落对环境变化比沉积物更敏感，细菌和原生动物群落对干扰的反应是不同的。为了应对更高养殖密度的挑战，水中共现网络中正相关的比例从 7 月到 11 月显著增加；而沉积物中的正相关比例则保持稳定。研究了细菌和原生动物之间的潜在生态相互作用和关键类群。这些结果提高了我们对养殖压力如何影响海洋牧场中微生物群落的理解。
