Net-pen aquaculture, one of the primary forms aquaculture in shallow lakes, has generated substantial economic benefits but also triggered eutrophication and ecological degradation. Therefore, accurate scientific dynamic monitoring areas is utmost importance. However, existing studies have predominantly employed annual monitoring, failing to fully exploit unique advantage synthetic aperture radar (SAR) imagery for seasonal, monthly or more frequent time scale monitoring. This study aimed develop an approach dynamics net-pen using Sentinel-1 series images. We integrated threshold segmentation temporal consistency checking extract spatial data on from eight typical lakes Jiangsu Province, eastern coastal provinces China, 2016 2021. yielded following results: (1) The VV polarization image offers a particularly noticeable contrast between structures their surroundings can help alleviate problem distinguishing changes error caused by misclassification actual that occurred. overall accuracy extraction results was over 85%. (2) not only enables analysis area fence length identify key points. For instance, Gehu Lake experienced rapid decline May November 2018, decrease while Eastern Taihu occurred September 2018 June 2019. (3) removal within Province primarily attributed policy responses. In response river lake action plan implemented observed both lengths across most These provide reference management ensuring effective implementation related policies.
