This study used microscopy-based quantitative enumeration to investigate the effects of large-scale cultivation on coastal water quality and phytoplankton communities. Data from April (cultivation period) and June (non-cultivation period) in 2018 and 2019 showed that cultivation increased pH and dissolved oxygen (DO). It also reduced nitrate-nitrogen (NO-N), nitrite-nitrogen (NO-N), phosphate-phosphorus (PO-P), total phosphorus (TP), and silicate-silicon (SiO-Si) concentrations. These changes indicate improved coastal water quality from cultivation. Nutrient levels rose again during the non-cultivation period. This suggests that water purification decreased without cultivation. Cultivation also lowered the dominance of . This led to a more diverse and stable phytoplankton community. Microscopic observation is valuable for quantifying larger phytoplankton species, and plays an important role in ecological monitoring. These findings provide insights for sustainable aquaculture and ecological restoration.
本研究采用基于显微镜的定量计数法，以调查大规模养殖对沿海水质和浮游植物群落的影响。2018年和2019年4月（养殖期）和6月（非养殖期）的数据表明，养殖提高了pH值和溶解氧（DO）。它还降低了硝酸盐氮（NO-N）、亚硝酸盐氮（NO-N）、磷酸盐磷（PO-P）、总磷（TP）和硅酸盐硅（SiO-Si）的浓度。这些变化表明养殖改善了沿海水质。在非养殖期，营养水平再次上升。这表明没有养殖时水净化能力下降。养殖还降低了[此处原文缺失相关内容]的优势度。这导致浮游植物群落更加多样化和稳定。显微镜观察对于量化较大的浮游植物物种很有价值，并且在生态监测中发挥着重要作用。这些发现为可持续水产养殖和生态恢复提供了见解。
