The large-scale outdoor culture of this species is, however, difficult during the summer season. To access the suitability of 'Tahiti Isochrysis' Isochrysis sp. (T-Iso) as a substitute for C. gracilis, we investigated the comparative nutritive value of these algae for larvae of greasy back shrimp, Metapenaeus ensis, by feeding experiments and fatty acids analyses. Further, T-Iso was cultured in large-scale outdoor tanks to determine its suitability for culture during the spawning season of M. ensis in summer. Larvae fed on T-Iso only were considerably delayed in development as compared to those fed on C. gracilis. On the eicosapentaenoic acid, which is known as an essential fatty acid of Kuruma prawn Penaeus japonicus larvae, the content of T-Iso was less than that of C. gracilis. Thus, the nutritive value of T-Iso seemed to be lower than that of C. gracilis. However, the survival rate and the development of larvae fed on T-Iso and C. gracilis mixture were better than those of larvae fed on C. gracilis or T-Iso in single use. Further, T-Iso showed a steady and constant increase in density in both 100-l and 500 -l outdoor tanks under high temperature conditions like Tetraselmis tetrathele and Nannochloropsis oculata. Therefore, T-Iso is useful as a supplemental food alga to C. gracilis, particularly during summer periods of high temperature and achieve a high survival rate and good growth of the shrimp larvae.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"キートセロス Chaetoceros gracilis はクルマエビ類幼生の餌料として広く利用されているが,屋外での安定した大量培養は困難である。そこで,屋外での大量培養が比較的容易なイソクリシス(タヒチ株)Isochrysis sp.を餌料として利用することを目的に,ヨシエビ Metapenaeus ensis 幼生への餌料価値を調べた。飼育試験及び含有高度不飽和脂肪酸組成から,タヒチ株の餌料価値はキートセロスに比べて劣るが,キートセロスとタヒチ株の併用給餌により幼生の成長及び生残率は,各藻類を単独に給餌した場合と比べ,向上することがわかった。また,タヒチ株は屋外培養が容易であることも確認できた。タヒチ株を併用することにより,キートセロスの給餌量を約1/2に軽減することができ,クルマエビ類種苗への安定した給餌が可能になると期待される。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_26_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/2010552829","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":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","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":"Okauchi, Masanori","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"岡内, 正典","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"オカウチ, マサノリ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Okauchi","familyNameLang":"en"},{"familyName":"岡内","familyNameLang":"ja"},{"familyName":"オカウチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Masanori","givenNameLang":"en"},{"givenName":"正典","givenNameLang":"ja"},{"givenName":"マサノリ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1902","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40372023","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40372023"}]},{"creatorNames":[{"creatorName":"Kawamura, Kouichi","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"河村, 功一","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"カワムラ, コウイチ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Kawamura","familyNameLang":"en"},{"familyName":"河村","familyNameLang":"ja"},{"familyName":"カワムラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kouichi","givenNameLang":"en"},{"givenName":"功一","givenNameLang":"ja"},{"givenName":"コウイチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"4255","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizukami, Yuzuru","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"水上, 譲","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"ミズカミ, ユズル","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Mizukami","familyNameLang":"en"},{"familyName":"水上","familyNameLang":"ja"},{"familyName":"ミズカミ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yuzuru","givenNameLang":"en"},{"givenName":"譲","givenNameLang":"ja"},{"givenName":"ユズル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2984","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Chaetoceros gracilis; food organism; Isochrysis sp.; larval rearing; Metapenaeus ensis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Nutritive Value of 'Tahiti Isochrysis' Isochrysis sp.
