ABSTRACT Since 1989, China has become the world's largest aquaculture producer through pond culture, significantly contributing to global food security but potentially posing environmental threats. However, little is known about changes in water quality at broad spatial and temporal scales, thus creating challenges sustainability of aquaculture. Herein, we explore China's ponds from 1989 2020 assess waterbody's health status optimize sustainable management strategies. This study highlights closely associated with practices, development, related policies. Seasonal regional farming variations impact quality, peak seasons Central North lowest scores. Pond initially declined rise intensive improved after 2012 adoption ecological engineering measures, eco‐farming policies supporting green development. Under a scenario combining these efforts, score 2035 projected increase by 57% level. These findings reveal that national initiatives advancements techniques public can enhance ponds, offering valuable insights into governance agriculture.
