Two types of hormone such as native LH-RH and des-Gly10 [D-Ala6]-LH-RH ethylamide (LH-RH ethylamide) were used in this study. In experiment I (native LH-RH), the initial control fish with an early phase of yolky oocytes showed an atrophy of ovary at the end of experiment, whereas the fish treated with LH-RH at a level of 100 µg showed acceleration of ovarian maturation and ovulation in some fish. All the fish received LH-RH 200 µg overcame against the ovarian maturation-suppressive condition and ovulated within 32 days. In experiment II (LH-RH ethylamide), the initial control fish with non-yolky oocyte showed a slight increase of GSI, whereas the fish treated with LH-RH ethylamide at a level of 50 or 100 µg ovulated within 53 days. Furthermore, LH-RH ethylamide was more potent in inducing maturation and ovulation of Ayu than native LH-RH. Consequently, LH-RH cholesterol pellet was demonstrated a longly active effect for yolk formation, final maturation and ovulation of fish held under the ovarian maturation-suppressive condition.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_13_11","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010393294","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"廣瀬, 慶二","creatorNameLang":"ja"}],"familyNames":[{"familyName":"廣瀬","familyNameLang":"ja"}],"givenNames":[{"givenName":"慶二","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"新井, 茂","creatorNameLang":"ja"}],"familyNames":[{"familyName":"新井","familyNameLang":"ja"}],"givenNames":[{"givenName":"茂","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"maturation; Ayu; LH-RH; cholesterol pellet","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"LH-RHコレステロールペレットによるアユの成熟促進","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LH-RHコレステロールペレットによるアユの成熟促進","subitem_title_language":"ja"},{"subitem_title":"Effect of LH-RH Cholesterol Pellet on Ovarian Maturation in Ayu, Plecoglossus altivelis","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2007590","relation_version_is_last":true,"title":["LH-RHコレステロールペレットによるアユの成熟促進"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-02T01:20:46.185619+00:00"}
