We also studied whether social isolated juvenile changes schooling behavior and whether social isolation affects the expression of neuropeptide hormone AVT).Juveniles exhibited schooling behavior at 2 weeks post-hatch (wph). After then, schooling behavior was increased until 8 wph. AVT expression was increased at 2 wph, and then, an increase of AVT expression was found until 12 wph. Schooling behavior in a juvenile isolated from 1 wph to 2 wph was decreased when isolated fish was introduced to grouped conspecifics. In isolated fish, AVT expression was slightly decreased. In the Avt gene knock-out medaka, the juveniles did not exhibit schooling behavior at 2 wph. This study indicates that social interaction among juveniles is necessary for behavioral development in medaka fish. It also suggests that AVT are associated with behavioral development.","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：2018～2020;   課題番号：18K05833;   研究分野：魚類行動生理学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","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_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":"KAGAWA, Nao"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"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":"加川, 尚"},{"creatorName":"カガワ, ナオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4192","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80351568","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=80351568"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-08"}],"displaytype":"detail","filename":"18K05833seika.pdf","filesize":[{"value":"160.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18K05833seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/22132/files/18K05833seika.pdf"},"version_id":"0c655083-5161-4b06-9c8d-0640197d7a5a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"社会性の発現","subitem_subject_scheme":"Other"},{"subitem_subject":"群れ形成行動","subitem_subject_scheme":"Other"},{"subitem_subject":"成長","subitem_subject_scheme":"Other"},{"subitem_subject":"神経ペプチド","subitem_subject_scheme":"Other"},{"subitem_subject":"メダカ","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":"魚類の発育に伴って社会性はいつ発現し、どのように発達するのか？","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"魚類の発育に伴って社会性はいつ発現し、どのように発達するのか？","subitem_title_language":"ja"},{"subitem_title":"When and how does medaka juveniles develop schooling behavior?","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-08"},"publish_date":"2021-11-08","publish_status":"0","recid":"22132","relation_version_is_last":true,"title":["魚類の発育に伴って社会性はいつ発現し、どのように発達するのか？"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-13T06:05:12.536334+00:00"}
