Abstract

At present, the supervision of offshore fishery resources is primarily based on the United Nations Convention on the Law of the Sea. The content mainly focuses on marine environmental protection and does not address the regulation of pollutants after they are discharged into the sea. After the nuclear discharge incident into the sea in Japan, it is evident that current international conventions, such as the Convention on Nuclear Safety and the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Substances, are unable to effectively regulate nuclear discharge into the sea within the scope of international law. On this basis, it is necessary to enhance the supervision mechanism for the fishing of pelagic fishery resources. This can be achieved by focusing on the pelagic fishing area, expanding the no-fishing zone towards the direction of nuclear sewage discharge through increased supervision, and the establishment of relevant laws. It is essential to prohibit local fishermen from catching fish exposed to radiation and implement policies to enhance control measures to mitigate the impact of nuclear sewage on pelagic fishery resources.
