Takifugu rubripes was investigated histologically. Paired primodial gonads were found on the dorsal peritoneal wall beneath the mesonephric ducts of a 2 day old, 3.49 mm in total length (TL). In almost all specimens at 20 days old range 7.21- 9.18 mm TL, the gonads had a small number of germ cells buried within numerous somatic cells. These germ cells began to develop at 40 days old range 18.92-20.67 mm TL when the gonads migrated to the anterior part of abdominal cavity. Sex differentiation of gonads occurred at 50 days old range 22.02-29.05 mm TL. At this stage, the gonads of ovarian nature characterized by prominent clusters of interstital tissue was confirmed. In specimens at 80 days old range 58.26-77.33 mm TL, metamorphosis to a demersal juvenile stage occurred and in the ovarian lamella-like structure with clusters of oogonia clear differentiation into the meiotic stage occurred within the ovary. Inside the testis stromal cells began to diffuse to form interstital tissue surrounding future seminal lobule anlage. The beginning of meiosis in the testes did not occur until 102 days after hatching. Gonadal sex ratio was investigated histologically using fish cultured in the laboratory and specimens caught from coastal waters of the Seto Inland Sea. No histological features of intersexuality were detected and the sex ratio was 1:1. The period of sexual differentiation of gonads corresponded to the change from a pelagic larval to a fully demersal stage in this species.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei National Fisheries Research Instituite","subitem_publisher_language":"en"}]},"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":"nnf_k_29_39","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/2010541831","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Suzuki, Nobuhiro","creatorNameLang":"en"},{"creatorName":"鈴木, 伸洋","creatorNameLang":"ja"},{"creatorName":"スズキ, ノブヒロ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Suzuki","familyNameLang":"en"},{"familyName":"鈴木","familyNameLang":"ja"},{"familyName":"スズキ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Nobuhiro","givenNameLang":"en"},{"givenName":"伸洋","givenNameLang":"ja"},{"givenName":"ノブヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3310","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Okada, Kazuhiro","creatorNameLang":"en"},{"creatorName":"岡田, 一宏","creatorNameLang":"ja"},{"creatorName":"オカダ, カズヒロ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Okada","familyNameLang":"en"},{"familyName":"岡田","familyNameLang":"ja"},{"familyName":"オカダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kazuhiro","givenNameLang":"en"},{"givenName":"一宏","givenNameLang":"ja"},{"givenName":"カズヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3308","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Kamiya, Naoaki","creatorNameLang":"en"},{"creatorName":"神谷, 直明","creatorNameLang":"ja"},{"creatorName":"カミヤ, ナオアキ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kamiya","familyNameLang":"en"},{"familyName":"神谷","familyNameLang":"ja"},{"familyName":"カミヤ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Naoaki","givenNameLang":"en"},{"givenName":"直明","givenNameLang":"ja"},{"givenName":"ナオアキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3307","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"tiger puffer; gonadal development; sexual differentiation; sex ratio","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":"トラフグ生殖腺の性分化過程と性比","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"トラフグ生殖腺の性分化過程と性比","subitem_title_language":"ja"},{"subitem_title":"Gonadal Development, Sexual Differentiation and Sex Ratio of Tiger Puffer, Takifugu rubripes","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003196","relation_version_is_last":true,"title":["トラフグ生殖腺の性分化過程と性比"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-11T01:05:00.157774+00:00"}
