On the basis of the cytological charactristic processes of the development of germ cells, the maturation processes in the gonads of both sexes were defined into the following five stages; (1)recovering, (2)developing, (3)premature, (4)mature, and (5) spent. Using the ratio of the number of individuals of each gonadal development stage to the total number, in conjunction with the gonad index (100 × gonad wet weight(g) /(test diameter: cm)² /test height (cm)), the annual reproductive cycle was evaluated for the females as: September to January as recovering period, February to March as developing period, April as premature period, May to June as mature period, and July to August as spawning period. The males exhibited a paralleled annual reproductive cycle to that of the females, i. e. September to January as recovering period, February to March as developing period, April as premature period, May to June as mature period, and July to August as sperm ejecting period.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai National Fisheries Research Institute","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":"snf_k_71_33","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/2010500422","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00393385","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0582-415X","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":"Yamasaki, Makoto","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"山崎, 誠","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ヤマサキ, マコト","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Yamasaki","familyNameLang":"en"},{"familyName":"山崎","familyNameLang":"ja"},{"familyName":"ヤマサキ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Makoto","givenNameLang":"en"},{"givenName":"誠","givenNameLang":"ja"},{"givenName":"マコト","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1841","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20392920","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20392920"}]},{"creatorNames":[{"creatorName":"Kiyomoto, Setsuo","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"清本, 節夫","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"キヨモト, セツオ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Kiyomoto","familyNameLang":"en"},{"familyName":"清本","familyNameLang":"ja"},{"familyName":"キヨモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Setsuo","givenNameLang":"en"},{"givenName":"節夫","givenNameLang":"ja"},{"givenName":"セツオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"481","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70371995","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70371995"}]}]},"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":"長崎県平戸島産ムラサキウニの生殖周期","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長崎県平戸島産ムラサキウニの生殖周期","subitem_title_language":"ja"},{"subitem_title":"Reproductive Cycle of the Sea Urchin Anthocidaris crassispina from Hirado Island, Nagasaki Prefecture","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205967"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-20"},"publish_date":"2024-06-20","publish_status":"0","recid":"2008170","relation_version_is_last":true,"title":["長崎県平戸島産ムラサキウニの生殖周期"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-06T01:28:14.083058+00:00"}
