A pool was constructed in a stream and six covers were placed in various locations on the pool. Thus, covers were placed along the bank on the upper, middle, and lower parts of the pool, and along the center line of the pool at the upstream, middle, and downstream parts of the pool. The placement of the cover mouth (a hole in the cover used for access and feeding) relative to the direction of stream flow was also varied in three ways: on the side of the cover, or on the downstream- or upstream-end of the cover. Twenty charr were then introduced into the pool and the number of charr hiding under each cover was counted under resting and stressed conditions. The charr preferred covers situated in the upstream part of the pool under both resting and stressed conditions, with this tendency being more apparent under stressed conditions. When resting, charr preferred covers with the cover mouths on the sides of the pool. However, under stressed conditions, charr showed no preference for the position of the cover mouth.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"イワナが好むカバーの条件を明らかにするため，カバーの選択性実験を試みた。淵内の 2 横断方向位置（岸沿い，中心線上）と 3 縦断方向位置（淵頭，淵途中，淵尻）の組み合わせの 6 箇所に，カバーを 1 個ずつ設置した。また，カバー開口部（魚の入口）の向きを 3 通り（流れに対して横，下流，上流）に設定した。カバー内の個体を計数した結果，平常時，警戒時ともに淵頭のカバーが好まれること，平常時に入口が横向きのカバーが好まれること，警戒時には入口向きとカバー使用個体数の間に特に関係がないことが示された。","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_8_2_73","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/2010902670","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":"山下, 耕憲","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山下","familyNameLang":"ja"}],"givenNames":[{"givenName":"耕憲","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"中村, 智幸","creatorNameLang":"ja"}],"familyNames":[{"familyName":"中村","familyNameLang":"ja"}],"givenNames":[{"givenName":"智幸","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"鈴木, 直樹","creatorNameLang":"ja"}],"familyNames":[{"familyName":"鈴木","familyNameLang":"ja"}],"givenNames":[{"givenName":"直樹","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"櫻本, 和美","creatorNameLang":"ja"}],"familyNames":[{"familyName":"櫻本","familyNameLang":"ja"}],"givenNames":[{"givenName":"和美","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_8_2_73.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010575/files/fra_t_8_2_73.pdf"},"version_id":"27862dbc-cdfc-4408-851c-d89751ecea6f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"イワナ; カバー; 保全; 生息場所","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"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":"淵におけるイワナのカバー選択性解明の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"淵におけるイワナのカバー選択性解明の試み","subitem_title_language":"ja"},{"subitem_title":"Pool cover preferences in white-spotted charr Salvelinus leucomaenis under resting and stressed conditions","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085691840"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010575","relation_version_is_last":true,"title":["淵におけるイワナのカバー選択性解明の試み"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:39:17.570165+00:00"}
