No individuals that were spawning or were just before spawning were found in sampled fish, suggesting the absence of a spawning area of this species off eastern Hokkaido. Gonado-somatic index (GSI) of adult fish gradually increased from September to January in both sexes, however, the measured oocyte diameters(0.5mm) of the most developed ovaries were considerably smaller than the value of fully grown vitellogenic oocytes(0.7mm) in a previous report of Yokota and Kawasaki (1990). The monthly catch was large in autumn and spring off eastern Hokkaido. The rate of maturing fish in the catch was over 50% in September and decreased to 10-20% in November to January. Judging from these results, in addition to some previous reports, we propose a tentative scheme of spawning migration of adult Laemonema longipes between eastern Hokkaido and the spawning area near Kanto. The minimum body lengths of primary maturation were 410mm in females and 358mm in males, respectively. Half of the female individuals matured at about 500mm in body length, and all female individuals matured at about 550mm in body length.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Hokkaido National Fisheries Research Institute","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"hnf_k_61_1","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/2010560437","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1015410X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0513-2541","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":"濱津, 友紀","creatorNameLang":"ja"},{"creatorName":"ハマツ, トモノリ","creatorNameLang":"ja-Kana"},{"creatorName":"Hamatsu, Tomonori","creatorNameLang":"en"}],"familyNames":[{"familyName":"濱津","familyNameLang":"ja"},{"familyName":"ハマツ","familyNameLang":"ja-Kana"},{"familyName":"Hamatsu","familyNameLang":"en"}],"givenNames":[{"givenName":"友紀","givenNameLang":"ja"},{"givenName":"トモノリ","givenNameLang":"ja-Kana"},{"givenName":"Tomonori","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"八吹, 圭三","creatorNameLang":"ja"},{"creatorName":"ヤブキ, ケイゾウ","creatorNameLang":"ja-Kana"},{"creatorName":"Yabuki, Keizou","creatorNameLang":"en"}],"familyNames":[{"familyName":"八吹","familyNameLang":"ja"},{"familyName":"ヤブキ","familyNameLang":"ja-Kana"},{"familyName":"Yabuki","familyNameLang":"en"}],"givenNames":[{"givenName":"圭三","givenNameLang":"ja"},{"givenName":"ケイゾウ","givenNameLang":"ja-Kana"},{"givenName":"Keizou","givenNameLang":"en"}]}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"北海道東部太平洋海域におけるイトヒキダラ Laemonema longipes の成熟度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北海道東部太平洋海域におけるイトヒキダラ Laemonema longipes の成熟度","subitem_title_language":"ja"},{"subitem_title":"Maturity of Laemonema longipes in the Pacific area off eastern Hokkaido","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716950587014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-08"},"publish_date":"2024-04-08","publish_status":"0","recid":"2001654","relation_version_is_last":true,"title":["北海道東部太平洋海域におけるイトヒキダラ Laemonema longipes の成熟度"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-17T00:40:35.003945+00:00"}
