天下谷・大友, 2008; 石川・大友, 2009; 藤本・石川, 2010; 山ノ目・石川, 2011; 菊池, 2012）．\nアユ産業には種苗放流が必須である一方で、生息地を無視した人為的な移植が繰り返されてきたことから、移植放流は人為的な分布域の拡大、過剰放流による天然魚の駆逐、遺伝子汚染等、生態的かく乱のリスクを伴うことが危惧されている（内田, 1997; 井口• 武島, 2006）。そのため、在来集団の遺伝的多様性の保全や資源の持続的利用を図る上で、在来集団と人工種苗集団の遺伝特性の把握は重要課題とされてきた。","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"TERUI, Sayuri"}]},{"nameIdentifiers":[{}],"names":[{"name":"OKUMURA, Taishi"}]},{"nameIdentifiers":[{}],"names":[{"name":"TSUKAGOSHI, Hideharu"}]},{"nameIdentifiers":[{}],"names":[{"name":"KAJIWARA, Shogo"}]},{"nameIdentifiers":[{}],"names":[{"name":"ABE, Syuiti"}]}]},"item_41_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15113/00011290","subitem_identifier_reg_type":"JaLC"}]},"item_41_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"岩手大学教育学部"}]},"item_41_source_id_25":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00017940","subitem_source_identifier_type":"NCID"}]},"item_41_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0367-7370","subitem_source_identifier_type":"ISSN"}]},"item_41_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学三陸水産研究センター"},{"subitem_text_value":"岩手大学三陸水産研究センター"},{"subitem_text_value":"岩手大学三陸水産研究センター"},{"subitem_text_value":"岩手大学教育学部, 岩手大学三陸水産研究センター"},{"subitem_text_value":"岩手大学三陸水産研究センター"}]},"item_41_version_type_27":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"照井, 沙友里"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥村, 大志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"塚越, 英晴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梶原, 昌五"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 周一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"arfe-v74pp149-156.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"arfe-v74pp149-156.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/11296/files/arfe-v74pp149-156.pdf"},"version_id":"34efa5a1-ffc4-4119-91a0-818356e591e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"遡上天然アユ","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝的多様性の保全","subitem_subject_scheme":"Other"},{"subitem_subject":"人口種苗","subitem_subject_scheme":"Other"},{"subitem_subject":"稗貫川","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"稗貫川遡上天然アユと同河川放流人工種苗の遺伝特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"稗貫川遡上天然アユと同河川放流人工種苗の遺伝特性"}]},"item_type_id":"41","owner":"3","path":["1596"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-28"},"publish_date":"2015-05-28","publish_status":"0","recid":"11296","relation_version_is_last":true,"title":["稗貫川遡上天然アユと同河川放流人工種苗の遺伝特性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T07:54:44.055535+00:00"}
