The population consists of two groups breeding in different years. Spring juveniles [Stage I, body length (B. L.) 4-20mm] mostly grow to Stage II individuals (B. L. 30 mm) by the following spring (1 year old). S. elegans seems to mature and reproduce (Stage III, B. L. 26-40mm) during the spring of the second year after hatching. Compared with populations in other waters of the world, specimens from the central Japan Sea have a longer life span and a larger maturity size. Such characteristics are similar to arctic populations, and this is considered to be caused by the low temperature (< 5˚C) of the Proper Water of the Japan Sea. We estimated the mean water temperature at which S. elegans grew as 0.8°C.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea 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":"js_k_47_95_103","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/2010562789","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":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"affiliationName":"西海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"セイカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Seikai National Fisheries Research Institute","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Nishihama, Shiro","creatorNameLang":"en"},{"creatorName":"西濱, 士郎","creatorNameLang":"ja"},{"creatorName":"ニシハマ, シロウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Nishihama","familyNameLang":"en"},{"familyName":"西濱","familyNameLang":"ja"},{"familyName":"ニシハマ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Shiro","givenNameLang":"en"},{"givenName":"士郎","givenNameLang":"ja"},{"givenName":"シロウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"583","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40372015","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40372015"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"日本海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"ニホンカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Japan Sea National Fisheries Research Institute","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Hirakawa, Kazumasa","creatorNameLang":"en"},{"creatorName":"平川, 和正","creatorNameLang":"ja"},{"creatorName":"ヒラカワ, カズマサ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Hirakawa","familyNameLang":"en"},{"familyName":"平川","familyNameLang":"ja"},{"familyName":"ヒラカワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kazumasa","givenNameLang":"en"},{"givenName":"和正","givenNameLang":"ja"},{"givenName":"カズマサ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1940","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50372024","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50372024"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Generation Length; Japan Sea; Sagitta elegans; Size distribution","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":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"日本海におけるキタヤムシの体長組成の季節変化と世代長の特徴","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本海におけるキタヤムシの体長組成の季節変化と世代長の特徴","subitem_title_language":"ja"},{"subitem_title":"Seasonal Change of the Size Distribution and Generation Length of the Chaetognath Sagitta elegans in the Japan Sea: Arctic Characteristics at a Temperate Latitude","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002440","relation_version_is_last":true,"title":["日本海におけるキタヤムシの体長組成の季節変化と世代長の特徴"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-12T06:55:13.028410+00:00"}
