The purposes of feeding are to avoid release during times of increasing water level in river, to prevent cannibalism, etc., and it is usually done on a temporary basis. Presently, the feeding/rearing period spans several months and takes into account such things as the water temperature of streams into which the fish are released, coastal environments during seaward migration, and target release weight of 1g or more. This system represents a major change from the time that artificial rearing was begun. This has been especially the case since the late 1970s, as vigorous technical developments, such as the introduction of optimum release techniques during the proper period and at the proper size of healthier fish. The development and dissemination of these techniques have contributed greatly to the increase in salmon resources. This paper examines the history of these technical developments.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"放流サケ稚魚への給餌は，わが国で本格的な人工ふ化放流事業が開始された 1888 年頃から行われていた。その目的は，増水時における放流の回避や共食いの防止などであり，一時的なものとして行われていた。現在では，飼育期間は放流する河川の水温や降海時における沿岸環境などを考慮して数ヵ月間にわたり，放流サイズも1 g 以上を目標とするなど，飼育開始当初に比較して大きく変遷してきた。特に 1970 年代後半からは，適期放流技術の導入に伴い，適正な時期に適正なサイズで健康な稚魚を放流するための技術開発が精力的に行われ，その技術の確立と普及が今日のサケ資源の増大に大きく貢献している。本稿ではその技術開発の歴史について記述した。","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_3_2_67","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/2010814280","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":"野川, 秀樹","creatorNameLang":"ja"}],"familyNames":[{"familyName":"野川","familyNameLang":"ja"}],"givenNames":[{"givenName":"秀樹","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"八木沢, 功","creatorNameLang":"ja"}],"familyNames":[{"familyName":"八木沢","familyNameLang":"ja"}],"givenNames":[{"givenName":"功","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_3_2_67.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010489/files/fra_t_3_2_67.pdf"},"version_id":"944144ef-8d45-4c11-ae78-9fa4e579d24e"}]},"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":"さけます類の人工ふ化放流に関する技術小史(飼育管理編)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"さけます類の人工ふ化放流に関する技術小史(飼育管理編)","subitem_title_language":"ja"},{"subitem_title":"Developlnent of Techniques for Rearing Juvenile Chum Salmon in Artificial Propagation in Japan","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085693113"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010489","relation_version_is_last":true,"title":["さけます類の人工ふ化放流に関する技術小史(飼育管理編)"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:33:20.323829+00:00"}
