Before yolk-sac larvae are used as feed, the fertilized eggs need to be disinfected to prevent viral nervous necrosis in the tuna seed. Electrolyzed seawater containing residual chlorine is a potential disinfectant for use in large-scale production of Spangled emperor eggs for Pacific bluefin tuna. However, the residual chlorine concentration declines rapidly because of the adherence of organic suspended matter to the surface of the eggs. To prevent this decline, we conducted experiments in which we varied two factors, namely the egg-rinse time before disinfection and the flow of electrolyzed seawater into the disinfection tanks. No decline in residual chlorine concentration was observed in disinfection with a 7.0-㎘/h electrolyzed seawater flow (2 million eggs per 0.5-㎘ tank) after a 2-h egg-rinse (8 million eggs per 0.5-㎘ tank, 1.0-㎘/h fresh seawater flow) using a total of 2.0 ㎘ of fresh seawater (four times the tank volume). Effective large-scale disinfection of eggs is possible with the use of sufficient egg-rinse and electrolyzed seawater flow.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"クロマグロの種苗生産においては，大量のふ化仔魚を必要とする。ウイルス性神経壊死症を防除するためには，餌料となるハマフエフキ受精卵の消毒が必要である。電解海水は消毒効果を有するが，卵表面に付着した有機物により残留塩素濃度が急激に低下する。本研究では，卵消毒中の残留塩素濃度の低下を防ぐため，卵洗浄時間および卵消毒中の電解海水の注水量の検討を行った。その結果，4 倍量の海水を用いて 2 時間の卵洗浄（500ℓ水槽に受精卵 800 万粒収容，注水量 1 ㎘ / h）を行った後，消毒水槽 500ℓに対して電解海水を 7 ㎘ / hで注水すること（受精卵 200 万粒収容）により，卵消毒中の残留塩素濃度の低下を防止でき，効果的な卵消毒が可能と考えられた。","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_4_1_15","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/2010830496","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":"樋口, 健太郎","creatorNameLang":"ja"}],"familyNames":[{"familyName":"樋口","familyNameLang":"ja"}],"givenNames":[{"givenName":"健太郎","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"江場, 岳史","creatorNameLang":"ja"}],"familyNames":[{"familyName":"江場","familyNameLang":"ja"}],"givenNames":[{"givenName":"岳史","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"田中, 庸介","creatorNameLang":"ja"}],"familyNames":[{"familyName":"田中","familyNameLang":"ja"}],"givenNames":[{"givenName":"庸介","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"久門, 一紀","creatorNameLang":"ja"}],"familyNames":[{"familyName":"久門","familyNameLang":"ja"}],"givenNames":[{"givenName":"一紀","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"西, 明文","creatorNameLang":"ja"}],"familyNames":[{"familyName":"西","familyNameLang":"ja"}],"givenNames":[{"givenName":"明文","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"二階堂, 英城","creatorNameLang":"ja"}],"familyNames":[{"familyName":"二階堂","familyNameLang":"ja"}],"givenNames":[{"givenName":"英城","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"塩澤, 聡","creatorNameLang":"ja"}],"familyNames":[{"familyName":"塩澤","familyNameLang":"ja"}],"givenNames":[{"givenName":"聡","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_4_1_15.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010501/files/fra_t_4_1_15.pdf"},"version_id":"0affcff0-716c-458a-8848-2fedd8537999"}]},"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":"クロマグロ種苗生産におけるウイルス性神経壊死症防除のためのハマフエフキ受精卵の大量消毒法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"クロマグロ種苗生産におけるウイルス性神経壊死症防除のためのハマフエフキ受精卵の大量消毒法","subitem_title_language":"ja"},{"subitem_title":"Large-scale Disinfection of Eggs of Spangled Emperor Lethrinus nebulosus to Prevent Viral Nervous Necrosis in Seed Production of Pacific Bluefin Tuna Thunnus orientalis","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085692831"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010501","relation_version_is_last":true,"title":["クロマグロ種苗生産におけるウイルス性神経壊死症防除のためのハマフエフキ受精卵の大量消毒法"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:34:14.656245+00:00"}
