The ghost-fishing mortality in a trap was represented with an experimental and theoretical equation as; fg(t) = a(1 – c t)·(1 - b)t. Annual gear loss rates were 0.2 in Japanese crab-trap fishery at the Sea of Japan, 0 in coastal fisheries in Thailand and Tanzania, while 0.08 to 0.23 in coastal fisheries in Southern Kyushu. Escape-ring as a countermeasure against ghost fishing was proved to have an additional function to increase large individuals in catch.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"660","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"21580231"}]},"item_8_version_type_14":{"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":"松岡, 達郎","creatorNameLang":"ja"},{"creatorName":"MATSUOKA, Tatsuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13592","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000080244268","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"安樂, 和彦","creatorNameLang":"ja"},{"creatorName":"ANRAKU, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"7073","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050274840","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","fileDate":[{"fileDateType":"Collected","fileDateValue":"2013-05-24"}],"filename":"21580231.pdf","filesize":[{"value":"285.6 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"21580231.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/13102/files/21580231.pdf"},"version_id":"341fb042-2374-4dd9-ab71-fb20d767d0f2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ゴーストフィッシング","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"逸失漁具","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"漁業","subitem_subject_language":"ja","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ゴーストフィッシング死亡量広域推定のための標準手法の日本海国際漁場への適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ゴーストフィッシング死亡量広域推定のための標準手法の日本海国際漁場への適用","subitem_title_language":"ja"},{"subitem_title":"Application of standard method for extensive estimation of ghost-fishing mortality to international fishing ground","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["159"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-10-01"},"publish_date":"2013-10-01","publish_status":"0","recid":"13102","relation_version_is_last":true,"title":["ゴーストフィッシング死亡量広域推定のための標準手法の日本海国際漁場への適用"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2025-07-07T06:37:29.258901+00:00"}
