Although previous studies have revealed that S. nudus is the causative grazer of the barren state by removal of and/or defense from the sea urchin, no practical efforts have been done for the improvement of fisheries ground. As the fishermen on the coast are aged and depopulated, the authors introduced citizen volunteer divers (CVD) for the removal of the sea urchin. The attempt was practiced on an urchin barren near Kamoenai Fishing Port on the southern coast of Shakotan Peninsula in September 2005. Twenty CVD (including a few instructors and staffs) removed sea urchins from two blocks (50 x 50 m, 4-8m in depth) during two dives (ca. 1 hr/dive) beside the control block; subsequent monthly removal by monitors (i.e., researchers) was done in one of the two blocks. In May 2006, the average standing crops of the seaweed (largely kelp) were 865g/m2 (monthly removed after the CVD activity) and 150g/m2 (removed once by CVD) but 0g/m2 in control, while the density of sea urchin were 0.1, 3.5 and 4.2/m2 , respectively. The results show that the introduction of CVD can aid the restoration of kelp beds.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_32_83","subitem_relation_type_select":"Local"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"WATANUKI, Akira","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"WATANUKI","familyNameLang":"en"}],"givenNames":[{"givenName":"Akira","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"AOTA, Toru","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"AOTA","familyNameLang":"en"}],"givenNames":[{"givenName":"Toru","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"OTSUKA, Eiji","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"OTSUKA","familyNameLang":"en"}],"givenNames":[{"givenName":"Eiji","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"KAWAI, Tadashi","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"KAWAI","familyNameLang":"en"}],"givenNames":[{"givenName":"Tadashi","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"IWAHASHI, Yoshitoshi","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"IWAHASHI","familyNameLang":"en"}],"givenNames":[{"givenName":"Yoshitoshi","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kuwahara, Hisami","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"桑原, 久実","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"クワハラ, ヒサミ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Kuwahara","familyNameLang":"en"},{"familyName":"桑原","familyNameLang":"ja"},{"familyName":"クワハラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Hisami","givenNameLang":"en"},{"givenName":"久実","givenNameLang":"ja"},{"givenName":"ヒサミ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"493","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60372059","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60372059"}]},{"creatorNames":[{"creatorName":"FUJITA, Daisuke","creatorNameLang":"en","creatorNameType":"Personal"}],"familyNames":[{"familyName":"FUJITA","familyNameLang":"en"}],"givenNames":[{"givenName":"Daisuke","givenNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_32_83.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010900/files/fra_k_32_83.pdf"},"version_id":"c324efaa-9378-4a98-b51f-7af7f8c0addd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"grazing;
