The sexuality of groupers is almost protogynous hermaphrodite. Therefore, in general, males of a species are larger than females. Larger males in the wild have decreased remarkably in numbers, owing to overfishing so, although both males and females are essential for offspring production, collecting larger male groupers from the field is very difficult. In this study, we developed sex control method of groupers. Androgen treatment easily induced normal sex change in Longtooth grouper. However, it was not possible to induce reverse sex Change (male-to-female) in Redspotted grouper. Therefore, it was considered that the sexual plasticity of grouper decreased after sex change.","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：2016～2018;   課題番号：16K07873;   研究分野：農学;   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"},{"subitem_text_value":"研究協力者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kobayashi, Yasuhisa"},{"subitem_text_language":"en","subitem_text_value":"Yamamoto, Masayuki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部; 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":"小林, 靖尚"},{"creatorName":"コバヤシ, ヤスヒサ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"山本, 昌幸"},{"creatorName":"ヤマモト, マサユキ","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":"2020-03-12"}],"displaytype":"detail","filename":"16K07873seika.pdf","filesize":[{"value":"455.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"16K07873seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/20670/files/16K07873seika.pdf"},"version_id":"0c3b3487-876a-45ca-9951-a998f9501ba5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ハタ科魚類","subitem_subject_scheme":"Other"},{"subitem_subject":"キジハタ","subitem_subject_scheme":"Other"},{"subitem_subject":"クエ","subitem_subject_scheme":"Other"},{"subitem_subject":"性転換","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":"ハタ科魚類の種苗生産技術の高度化: 成熟・性・不妊化に関する生理学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ハタ科魚類の種苗生産技術の高度化: 成熟・性・不妊化に関する生理学的研究","subitem_title_language":"ja"},{"subitem_title":"Sophistication of aquaculture technique for grouper : Physiological studies on maturation, sex change and sterilization.","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4550"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-03-12"},"publish_date":"2020-03-12","publish_status":"0","recid":"20670","relation_version_is_last":true,"title":["ハタ科魚類の種苗生産技術の高度化: 成熟・性・不妊化に関する生理学的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-20T01:45:24.338957+00:00"}
