I also estimated the possible contribution of drifting seaweed to the early life history of demersal fishes as habitats. Approximately 130 species of juvenile fishes associated with drifting seaweed have been reported to be found in the waters surrounding the Japanese archipelago north of Kyushu. The fish fauna varied by the location of sea area, however, except for the yellowtail juveniles, demersal fishes are more common and abundant than pelagic fishes in each sea area. Therefore, I proposed to classify juvenile fishes that are associated with drifting seaweed into “essential residents” and “opportunistic residents” based on whether it is essential for them to accompany drifting seaweed during a certain period of their early life history. In addition, I proposed the division of “opportunistic resident” into “active opportunistic resident” and “passive opportunistic resident”. Furthermore, I suppose that the development of “essential resident” and “active opportunistic resident” drifting seaweed was related to the reduction in mortality rate during and around primary metamorphosis due to the extension of the pelagic life period.","subitem_description_language":"en"},{"subitem_description":"日本列島周辺海域の表層を漂う流れ藻に随伴する稚魚・幼魚の出現状況を整理し，底魚類の初期生活史における流れ藻の役割について検討した。対象海域全体では約130種の稚魚・幼魚が確認され，海域によって魚類相は異なるが各海域ともブリ稚魚を除くと底魚類が多く出現する。生活史において流れ藻への随伴が必須か否かに着目し，流れ藻に随伴する稚魚・幼魚の生活型を「必須居住者」と「機会居住者」に区分し，後者を「受動的機会居住者」と「能動的機会居住者」へ細分することを提案した。また，「必須居住者」と「能動的機会居住者」の流れ藻への稚魚の随伴様式は，浮遊期間の延長による一次的変態時の減耗率軽減に関連していると想定した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ファイル名末尾に”_abs_j”のファイルは和文要旨","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57348/0002013994","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research and Educaton Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fish_t_17_67","subitem_relation_type_select":"Local"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"水産機構ホームページ該当巻号目次"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.fra.go.jp/home/kenkyushokai/book/fish_tech/17-2.html","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_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":"Nagasawa, Toru","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"永澤, 亨","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"ナガサワ, トオル","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Nagasawa","familyNameLang":"en"},{"familyName":"永澤","familyNameLang":"ja"},{"familyName":"ナガサワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toru","givenNameLang":"en"},{"givenName":"亨","givenNameLang":"ja"},{"givenName":"トオル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"569","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90443382","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90443382"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-03-28"}],"filename":"fish_t_17_67.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2013994/files/fish_t_17_67.pdf"},"version_id":"00ba330d-27c4-45bf-bfb1-e3090c83777f"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-03-28"}],"filename":"fish_t_17_67_abs_j.pdf","filesize":[{"value":"210.2 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2013994/files/fish_t_17_67_abs_j.pdf"},"version_id":"7db73466-79f7-4b46-8267-9fc00748c19f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"流れ藻;
