| Outline of Final Research Achievements |
The aim of this study is to elucidate the radiocesium contamination mechanisms of marine and freshwater fish, and to contribute the restoration of Fukushima’s fisheries based on the scientific knowledge disseminated through scientific papers, international conference and local dialogue meeting etc. This study has revealed that radiocesium concentrations in marine fish were constantly low, while those in freshwater fish inhabiting water bodies near the Fukushima Dai-ichi Nuclear Power Plant were still extremely high in terms of Japanese food safety standard. Continuous radiocesium uptake through food web were inferred to be the primarily cause of the higher radiocesium contamination levels in freshwater fish.
The obtained results were frequently disseminated through international journals, local dialogue meetings, and discussions at the Fukushima’s local fisheries restoration council, which have contributed the restoration of Fukushima’s fisheries.
