Periphyton have been widely applied in aquaculture systems, however, little information is available on how periphyton respond to such high nutrient levels in water. Thus, changes in the morphological characteristics, community structure, and metabolic function of periphyton under high eutrophic waters were evaluated. The results indicated that the morphology of periphyton was affected by increasing the nutrient concentration of water, which shifted the micromorphology of periphyton from spheriform to filamentous. The periphyton under higher water nutrient levels were able to utilize more carbon source types. Additionally, higher water nutrient levels increased the bacterial and protozoal proportions in periphyton. This study fills the gap in knowledge about the responses of periphytic communities to extremely eutrophic waters. It provides valuable information on the full understanding of the periphyton-nutrient relationship in aquaculture systems, which is beneficial for regulating the microbial species or communities in periphyton by manipulating the nutrient levels in water.
底栖藻类被广泛应用于水产养殖系统中，然而，关于底栖藻类如何应对水中如此高的营养水平的信息却很少。因此，评估了高富营养化水体中底栖藻类的形态特征、群落结构和代谢功能的变化。结果表明，底栖藻类的形态受水体营养浓度增加的影响，使底栖藻类的微观形态从球形变为丝状。在较高的水体营养水平下，底栖藻类能够利用更多类型的碳源。此外，较高的水体营养水平增加了底栖藻类中细菌和原生动物的比例。本研究填补了底栖藻类群落对极富营养化水体响应的知识空白。它为全面了解水产养殖系统中底栖藻类与营养物质的关系提供了有价值的信息，这有利于通过控制水体中的营养物质来调节底栖藻类中的微生物种类或群落。
