Copepod eggs and nauplii were numerically the most important food items. Food composition changed as the larvae grew; the proportion of eggs decreased with increasing size of larvae, while correspondingly the proportion of nauplii increased. The nauplii eaten consisted of various species. As a whole, cyclopoid (Oithona spp.) nauplii were the most important dietary component, with calanoid (mainly Paracalanus type) nauplii second. Such food composition is in part a reflection of the abundance and species composition of copepods in the field. Maximum prey size (length and width) increased with size (SL) of larvae, whereas minimum prey size increased less; the size of prey consumed showed a large range in sizes, from 0.07 to 0.45mm in length and 0.05 to 0.20mm in width. Within these size constraints, rare copepod species such as Calanus sinicus and Oithona plumifera seem to make a major contribution to larval growth (SL: 5.1 to 8.0mm) because of their large body size, although the more abundant and smaller sized copepods (possibly Oithona similis) are more commonly eaten.","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_46_65_75","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/2010541839","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":"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"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Goto, Tsuneo","creatorNameLang":"en"},{"creatorName":"後藤, 常夫","creatorNameLang":"ja"},{"creatorName":"ゴトウ, ツネオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Goto","familyNameLang":"en"},{"familyName":"後藤","familyNameLang":"ja"},{"familyName":"ゴトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tsuneo","givenNameLang":"en"},{"givenName":"常夫","givenNameLang":"ja"},{"givenName":"ツネオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1820","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10371890","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10371890"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"copepod nauplii; cyclopoids; gut contents; Oithona spp.; Toyama Bay; Sardinops melanostictus","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":"日本海南部富山湾におけるマイワシ (Sardinops melanostictus) 仔魚の餌料","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本海南部富山湾におけるマイワシ (Sardinops melanostictus) 仔魚の餌料","subitem_title_language":"ja"},{"subitem_title":"Diet of Larval Sardine, Sardinops melanostictus in Toyama Bay, Southern Japan Sea","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":"2002445","relation_version_is_last":true,"title":["日本海南部富山湾におけるマイワシ (Sardinops melanostictus) 仔魚の餌料"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T07:06:19.554914+00:00"}
