Report on the Monitoring of Radionuclides in Fishery Products (Summary) Report on the Monitoring of Radionuclides in Fishery Products (Summary) April 2015 Fisheries Agency of Japan Update of the Report by FAJ • Since the Fukushima Daiichi NPS accident in March 2011, the Japanese government, local governments and relevant organizations have worked cooperatively for ensuring safety of fishery products. • The FAJ report in May 2014 gave a summary of information and knowledge obtained by then, in order to promote accurate understanding of Japanese fishery products domestically/internationally. • Almost four years have passed since the accident, and the level of radioactive Cs in fishery products has declined substantially. • However, concerns still remain among some consumers, and some countries and regions still maintain their import restrictions. → FAJ updated the Report in April 2015. 1 Ⅰ Measures to Secure the Safety of Fishery Products 1.

Framework for Securing the Safety of Fishery Products ○ The Japanese Government’s Nuclear Emergency Response Headquarters establishes and updates “Concepts of Inspection Planning and the Establishment and Cancellation of Items and Areas to which Restriction of Distribution and/or Consumption of Foods concerned Applies” (“the Guideline” hereinafter). ○ Monitoring is focused on major fish species and those species which exceeded 50 Bq/kg in the previous year. ○ For the species which exceeds the standard limit in more than one point, the restrictions on distribution are imposed by the head of the Nuclear Emergency Response Headquarters (i.e. the Prime Minister of Japan). 3 2. Monitoring Plan of Local Governments In case of Chiba Prefecture 6 zones: 4 fishing zones, inland ○ Each local government establishes fishery and aquaculture Monitoring Plan in accordance with “the Guideline” ○ Local governments divide their marine fish areas by taking account of fishing activities or distribution of fish species. ○ Monitoring is conducted for each zone based on monitoring plans. ○ If radioactive cesium levels exceed or are close to the standard limit, the frequency of monitoring is intensified. 4 3. Actions to be taken in the event that the standard limit is exceeded ○ In case a fishery product exceeds the standard limit (100 Bq/kg), the lot containing the product is recalled pursuant to the Food Sanitation Act. ○ In addition, the distribution of the fishery species is suspended, either by the local government’s request or the head of the Nuclear Emergency Response Headquarters’ imposition, depending on the following inspection results. Workflow for voluntary distribution suspension or regulatory shipping restriction for sea fish.

The chart only shows a typical example. 5 4. Inspection Results of Fishery Products (1) ○ Since the accident (March 2011) to January 2015, about 66,500 samples of more than 400 fish species were inspected for cesium. ○ Those inspection results show the following: • Shallow‐sea fishes, Squid and Octopus; While radioactive cesium concentrations were high in the immediate post‐accident period, the levels dropped off quickly. • Migratory fishes; No sample has ever exceeded 100 Bq/kg.

The Explorers Education Programme team provides engaging activities, resources and support for teachers, children and the education network, delivering ocean literacy to primary schools. We aim to inspire children and educators to learn about our marine and maritime identity and heritage, as well as making informed and responsible decisions regarding the ocean and its resources. We communicate about the ocean in a meaningful way, increasing the awareness and understanding of our marine biodiversity, the environment, as well as the opportunities and social benefits of our ocean wealth. To help inspire children learning about the ocean, we have developed a series of teaching materials and resources about Squid! Check out our Explorers books: Cephalopod Science Investigations – Learning about Squid 101; My CSI Squid Workbook.

Seafood Watch® denes sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of aected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from www.seafoodwatch.org. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans.

We examined the influence of environmental factors in potential spawning Edited by: grounds of the winter cohort, approximated from Japanese and South Korean catch Eduardo Almansa, Spanish Institute of Oceanography and catch per unit effort (CPUE) data of Japanese flying squid. Annual spawning ground (IEO), Spain dynamics were constructed using sea surface temperature (SST), submarine elevation Reviewed by: and mean Kuroshio axis data from 1979 to 2018. Based on these information, we Daniel Oesterwind, Thünen-Institut, Germany generated a suite of spawning ground indices including suitability SST-weighted area of Dharmamony Vijai, potential spawning ground (SSWA), mean values (January–April) of suitable SST (MVSS), National Centre for Biological and the meridional position (MP) of SST isolines (18–24◦C).
