In the recirculating system, the effluent water was treated with a protein skimmer and biofilter, and added continuously to the culture tank at a flow rate of 650 L /day. Rotifer cultures were continued to 25 days in media with 25 ºC and salinity 26, in comparison with a flow through system where new diluted seawater was added continuously. Total harvests of rotifer in the recirculating and flow through systems were 39.1-40.2 billion and 38.0-39.7 billion, respectively. In the recirculating system, nitrate concentration gradually increased, while the poisonous unionized ammonia concentration remained low in both systems. By use of a recirculating system, the volume of waste water per day was decreased by approximately 97%. The initial cost of a recirculating system was 1.69 times higher than the flow through system, while the running cost was 0.56 times lower. Supposing that more than five rounds of 25days’ culture are carried out, the initial investment can be collected, and the cost of rotifer production will go down less than the flow-through system.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"簡易で，効率よく懸濁物除去やアンモニアの硝化が可能な循環式の S 型ワムシ連続培養システムを製作し，培養水槽1000L，水温25 ℃，塩分26psu，循環水量650L/ 日の条件で 25 日間の培養実験を行い，流水式培養と比較した。循環式では硝酸の蓄積が生じるものの，アンモニアの蓄積は流水と同様の傾向で有害な非解離アンモニアの蓄積は 2.0mg/L 以下であった。総収穫数は390.8 ～ 402.1 億個体であり，流水式の 379.7 ～ 396.5 億個体と同等であった。また，廃水量は 20L/ 日程度と流水式の約 1/30 であり，培養コストも 5 回程度繰り返すことで流水式より安価であった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_6_1_45","subitem_relation_type_select":"Local"}}]},"item_10001_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/2010870177","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森田, 哲男","creatorNameLang":"ja"}],"familyNames":[{"familyName":"森田","familyNameLang":"ja"}],"givenNames":[{"givenName":"哲男","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小磯, 雅彦","creatorNameLang":"ja"}],"familyNames":[{"familyName":"小磯","familyNameLang":"ja"}],"givenNames":[{"givenName":"雅彦","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"今井, 正","creatorNameLang":"ja"}],"familyNames":[{"familyName":"今井","familyNameLang":"ja"}],"givenNames":[{"givenName":"正","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"手塚, 信弘","creatorNameLang":"ja"}],"familyNames":[{"familyName":"手塚","familyNameLang":"ja"}],"givenNames":[{"givenName":"信弘","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"山本, 義久","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山本","familyNameLang":"ja"}],"givenNames":[{"givenName":"義久","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_6_1_45.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010544/files/fra_t_6_1_45.pdf"},"version_id":"9c8f0c34-7a24-4bdd-9ce8-cc57e75f4aea"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"循環式培養システムを用いたシオミズツボワムシの連続培養","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"循環式培養システムを用いたシオミズツボワムシの連続培養","subitem_title_language":"ja"},{"subitem_title":"Continuous Culture of the Rotifer Brachionus plicatilis sp. complex Using a Recirculating System","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085692335"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010544","relation_version_is_last":true,"title":["循環式培養システムを用いたシオミズツボワムシの連続培養"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:37:11.014091+00:00"}
