The daily rhythm of diel vertical migration of Japanese eels observed in the open sea and their spawning area was the same behavior found in all areas during their spawning migration. A clear relationship between the upper and lower limits of migration and the sun and moon light and water temperature was found. Their experienced temperatures estimated from the development rate of collected eggs was not significantly different from the environmental temperature from CTD data, only if spawning occurred at 1:00 at night 3 days before new moon in all cases. Therefore, we hypothesize that Japanese eels spawn at about 1:00 a.m. and internal tide patterns may contribute to the mechanisms that determine the places they spawn in the open ocean.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2014～2016;   課題番号：26450268;   研究分野：魚類生態学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26450268/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"WATANABE, Shun"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡邊, 俊"},{"creatorName":"ワタナベ, シュン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-01"}],"displaytype":"detail","filename":"26450268seika.pdf","filesize":[{"value":"174.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"26450268seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18835/files/26450268seika.pdf"},"version_id":"9bf62dd7-7d90-489d-bb23-32a5a5b17bc6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ニホンウナギ","subitem_subject_scheme":"Other"},{"subitem_subject":"卵","subitem_subject_scheme":"Other"},{"subitem_subject":"内部潮汐","subitem_subject_scheme":"Other"},{"subitem_subject":"UNA-CAM","subitem_subject_scheme":"Other"},{"subitem_subject":"ポップアップタグ","subitem_subject_scheme":"Other"},{"subitem_subject":"日周鉛直移動","subitem_subject_scheme":"Other"},{"subitem_subject":"光","subitem_subject_scheme":"Other"},{"subitem_subject":"水温","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":"ニホンウナギの産卵回遊生態の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ニホンウナギの産卵回遊生態の解明"},{"subitem_title":"The spawning ecology of Japanese eels","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4374"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-01"},"publish_date":"2017-11-01","publish_status":"0","recid":"18835","relation_version_is_last":true,"title":["ニホンウナギの産卵回遊生態の解明"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:51:51.106558+00:00"}
