The survey indicated that the following were likely to have been causing decreases in hatching ratios: subjecting fish to excessive stress at capture; prolonged keeping of adult fish at room temperature until fertilization; and the use of high water temperatures for fertilization. Correction of these problems would require technical innovations， including the introduction of fishways for adult capture; the use of adult holding ponds to shorten the time taken for the fertilization process; and the securing of water of a temperature appropriate for fertilization. These technical innovations would improve hatching ratios.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"サケの増殖技術を向上させるため，各地の孵化場で用いられている増殖手法を調査し，問題点を整理した。その結果，捕獲時に魚が受ける過度なストレス，採卵用親魚の撲殺から採卵までの長時間放置，受精作業時の高水温用水の使用が孵化率を低下させている可能性が示唆された。これらの問題点を改善するためには，魚道式捕獲法の導入，蓄養池を利用した採卵作業時間の短縮，適水温孵化用水の確保等の技術改革によってふ化率を向上させる必要がある。","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_1_2_29","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/2010781765","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":"宮本, 幸太","creatorNameLang":"ja"}],"familyNames":[{"familyName":"宮本","familyNameLang":"ja"}],"givenNames":[{"givenName":"幸太","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"平澤, 勝秋","creatorNameLang":"ja"}],"familyNames":[{"familyName":"平澤","familyNameLang":"ja"}],"givenNames":[{"givenName":"勝秋","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"宮内, 康行","creatorNameLang":"ja"}],"familyNames":[{"familyName":"宮内","familyNameLang":"ja"}],"givenNames":[{"givenName":"康行","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"戸叶, 恒","creatorNameLang":"ja"}],"familyNames":[{"familyName":"戸叶","familyNameLang":"ja"}],"givenNames":[{"givenName":"恒","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_1_2_29.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010459/files/fra_t_1_2_29.pdf"},"version_id":"0f9f47db-94bd-463a-8665-c8d3b8a775b8"}]},"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":"サケ人工増殖における親魚捕獲、蓄養および受精作業の現状と問題点","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サケ人工増殖における親魚捕獲、蓄養および受精作業の現状と問題点","subitem_title_language":"ja"},{"subitem_title":"Adult Capture, AdultHolding for Maturation, andFer tilization in Artificial Propagation of the Chum Salmon (Oncorhynchus ket，α): Current Status and Problems","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085693698"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010459","relation_version_is_last":true,"title":["サケ人工増殖における親魚捕獲、蓄養および受精作業の現状と問題点"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:31:06.267112+00:00"}
