Notochord flexion occurs by 7 mm SL. Transformation from postflexion larvae to pelagic juveniles occurs between 10-13 mm SL. Larvae and pelagic juveniles of S. hubbsi were sampled in nearshore waters, but were not found in offshore regions such as the Chokai Bank. Planktonic larvae and pelagic juveniles mainly inhabit in the surface layers. Flexion larvae fed mainly on calanoid copepodites, with copepod nauplii as second most important by number. Postflexion and transforming larvae also fed mainly on calanoid copepodites with invertebrate eggs as second most important by number. Pelagic juveniles also fed on calanoid copepodites. I estimate that large size of larvae at parturition, rapid development and short planktonic period ensures minimum offshore dispersal in this species.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"胎生であるヨロイメバルは体長約5.5mmの屈曲期仔魚として産出され,体側を黒色素胞が広く覆うことを特徴とする.脊索後端の上屈は体長7mmまでに終了し,後屈曲期仔魚となる.変態は体長10-13 mmで行われ,その後は浮遊期稚魚となる.浮遊期仔稚魚は沿岸の海域で出現し,向瀬や鳥海礁などの沖合岩礁域では出現しない.浮遊期の仔稚魚は海表面近くに分布する.また,出現期間が短いことから浮遊期間も短いものと推定された.産出直後の屈曲期仔魚から餌生物の主体は体長1mm台のカラヌス目かいあし類であり,これは浮遊期を通じて共通であった.ヨロイメバルは比較的大きなサイズで産出され,発育も早く,浮遊期間が短いという初期生活史の特性を有する.このパターンは浮遊期における沖合への逸散を最小限にするのに有効で,沿岸・岩礁性種の生活史戦略としては典型的なものの一つであると考えられる.","subitem_description_language":"ja","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_49_97_108","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/2010591255","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":"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":"Nagasawa, Toru","creatorNameLang":"en"},{"creatorName":"永沢, 亨","creatorNameLang":"ja"},{"creatorName":"ナガサワ, トオル","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Nagasawa","familyNameLang":"en"},{"familyName":"永沢","familyNameLang":"ja"},{"familyName":"ナガサワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toru","givenNameLang":"en"},{"givenName":"亨","givenNameLang":"ja"},{"givenName":"トオル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"569","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90443382","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90443382"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Sebastes; larval development; distribution; feeding; Sea of Japan; Sado","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":"佐渡海峡におけるヨロイメバルの初期生活史","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"佐渡海峡におけるヨロイメバルの初期生活史","subitem_title_language":"ja"},{"subitem_title":"Early Life History of Yoroi-mebaru, Sebastes hubbsi, in the Sado Strait, Sea of Japan","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":"2002422","relation_version_is_last":true,"title":["佐渡海峡におけるヨロイメバルの初期生活史"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-12T04:24:22.379281+00:00"}
