Ecological succession is vital for forecasting ecosystem responses to environmental changes and their future states. Zooplankton, a primary natural food source in aquaculture, plays a crucial role in maintaining ecosystem function. Thus, understanding how zooplankton communities respond to environmental changes is essential for economic and ecological outcomes. In this study, we examined three types of aquaculture ponds (crab, crayfish, and fish ponds) with over 10 years of history and analyzed 27 environmental factors potentially influencing zooplankton dynamics throughout the year. Our results showed that Rotifera was the most abundant group in all three pond types, followed by Protista, Cladocera, and Copepoda. The dominant species across different seasons and ponds were , , and . The alpha diversity of zooplankton was influenced by various environmental factors across different pond types, with significant effects of antibiotics observed only in the fish ponds. The temporal and spatial distributions of zooplankton communities varied significantly. Deterministic processes, driven primarily by temperature and ammonia nitrogen, were identified as the primary mechanisms influencing zooplankton community assembly in freshwater aquaculture ponds. These findings inform management practices aimed at regulating key environmental drivers and optimizing zooplankton dynamics, with implications for maintaining ecosystem stability and productivity and, ultimately, supporting sustainable aquaculture.

生态演替对于预测生态系统对环境变化及其未来状态的响应至关重要。浮游动物是水产养殖中的主要天然食物来源，在维持生态系统功能方面发挥着关键作用。因此，了解浮游动物群落如何响应环境变化对于经济和生态成果至关重要。在本研究中，我们考察了三个具有超过10年历史的水产养殖池塘类型（蟹塘、小龙虾塘和鱼塘），并分析了全年可能影响浮游动物动态的27个环境因素。我们的结果表明，轮虫是所有三种池塘类型中数量最多的类群，其次是原生动物、枝角类和桡足类。不同季节和池塘中的优势种分别是 、 和 。浮游动物的α多样性受到不同池塘类型中各种环境因素的影响，仅在鱼塘中观察到抗生素有显著影响。浮游动物群落的时间和空间分布差异显著。确定性过程主要由温度和氨氮驱动，被确定为影响淡水养殖池塘中浮游动物群落组装的主要机制。这些发现为旨在调节关键环境驱动因素和优化浮游动物动态的管理实践提供了信息，对维持生态系统稳定性和生产力以及最终支持可持续水产养殖具有重要意义。
