A precipitous rise in the environmental salinity caused a loss of appetite, reduced growth, and a decreased feed efficiency of chum salmon. The daily feeding rate of chum salmon in seawater was resumed in the second week of the experimental period and thereafter exceeded the rate of that in freshwater. While a decreased daily growth rate and feed efficiency under high salinity was maintained throughout the 35 days of the experimental period, the higher the salinity provided, the lower the growth rate attained. Ayu, which migrate in an opposite direction from chum salmon, exhibited the same reduced growth rate under high salinity after an acclimatization period of 12 days. Contrary to the case of chum salmon, the daily feeding rate of ayu was higher in freshwater. With an increase in the salinity, both species showed decreased whole body protein and fat retention.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"サケ稚魚の成長と塩分との関係を,0,8,16,24,32‰の5条件下で5週間の飽食給餌での飼育実験により調べた.飼育水塩分の急激な上昇により,第1週には摂餌率,成長率,飼料効率の低下が認められた.高塩分下における摂餌率は第2週には淡水区の水準まで回復し,その後これを上回った.一方,成長率および飼料効率は実験期間を通して淡水区の値より低く,塩分が高いほど成長が悪い結果を得た.サケとは逆に海水から淡水への回遊を行うアュ稚魚について,海水および淡水でそれぞれ28日間の飼育を行ったところ,成長率はサケと同様に海水中で低かったが,摂餌率は淡水中で高くなった.全魚体への蛋白質および脂質の蓄積率は両種とも塩分の上昇により低下した.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"作成者","attribute_value_mlt":[{"subitem_radio_item":["吉","田"],"subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"js_k_36_1_14","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/2010341331","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":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Koshiishi, Yuichi","creatorNameLang":"en"},{"creatorName":"輿石, 裕一","creatorNameLang":"ja"},{"creatorName":"コシイシ, ユウイチ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Koshiishi","familyNameLang":"en"},{"familyName":"輿石","familyNameLang":"ja"},{"familyName":"コシイシ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yuichi","givenNameLang":"en"},{"givenName":"裕一","givenNameLang":"ja"},{"givenName":"ユウイチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"499","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60371994","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60371994"}]}]},"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":"サケおよびアユ稚魚の摂餌,成長ならびに飼料効率に対する塩分の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サケおよびアユ稚魚の摂餌,成長ならびに飼料効率に対する塩分の影響","subitem_title_language":"ja"},{"subitem_title":"Effect of on Food Intake, Growth and Feed Efficiency of Chum Salmon, Oncorhynchus keta (WALBAUM), and Ayu, Plecoglossus altivelis TEMMINCK et SCHLEGEL","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002516","relation_version_is_last":true,"title":["サケおよびアユ稚魚の摂餌,成長ならびに飼料効率に対する塩分の影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-27T04:47:22.561833+00:00"}
