Turning behavior during the day and night was analyzed from the results of three-dimensional trajectories of the tagged tuna. Turning of tuna during the day was sharper than that during the night. We recorded swimming depth using relative entropy to detect feeding and abnormal behaviors. Offshore Bluefin tuna aquaculture has a low yield ratio due to mortality of the colliding tuna in net cages. These results will help understand tuna behavior to improve net cages and prevent fish from colliding.","subitem_description_type":"Other"}]},"item_8_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ヨネヤマ, カズヨシ"}]}]},"item_8_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"YONEYAMA, Kazuyoshi"}]}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"666","subitem_subject_scheme":"NDC"}]},"item_8_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_8_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"23780200"}]},"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"米山, 和良"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"23780200_米山和良.pdf","filesize":[{"value":"159.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"23780200_米山和良.pdf","url":"https://ir.kagoshima-u.ac.jp/record/11974/files/23780200_米山和良.pdf"},"version_id":"33273ce7-7af6-4b68-8776-a959918ae7b8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"クロマグロ　","subitem_subject_scheme":"Other"},{"subitem_subject":"バイオロギング","subitem_subject_scheme":"Other"},{"subitem_subject":"養殖","subitem_subject_scheme":"Other"},{"subitem_subject":"3次元遊泳行動","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":"浮沈式生簀での養成を目標とした養殖クロマグロの遊泳行動の分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"浮沈式生簀での養成を目標とした養殖クロマグロの遊泳行動の分析"}]},"item_type_id":"8","owner":"3","path":["159"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-20"},"publish_date":"2015-05-20","publish_status":"0","recid":"11974","relation_version_is_last":true,"title":["浮沈式生簀での養成を目標とした養殖クロマグロの遊泳行動の分析"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:53:04.758070+00:00"}
