The mean intensity of the parasite on masu salmon was 10.3 (intensity range, 1-26). There was a significant increase in intensity of infection as the size of the host fish increased. Most of the copepods found were mature adult females, followed by chalimus larvae and young adult females. The mature adult females were attached almost exclusively to the gills and the inner surface of the operculum. The chalimus larvae were found on the gills. The distal ends of the gill filaments attached by adult females were damaged, but there were no significant correlations between condition factor and intensity of infection. This paper is the first confirmed record of S. californiensis from Hokkaido.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"さけ・ます資源管理センター","subitem_publisher_language":"ja"},{"subitem_publisher":"the National Salmon Resources Center","subitem_publisher_language":"en"}]},"item_10002_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"80015917411","subitem_relation_type_select":"NAID"}}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"salmon-k-k_5-2","subitem_relation_type_select":"Local"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11339120","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-7556","subitem_source_identifier_type":"PISSN"}]},"item_10002_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":"長澤, 和也","creatorNameLang":"ja"},{"creatorName":"ナガサワ, カズヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Nagasawa, Kazuya","creatorNameLang":"en"}],"familyNames":[{"familyName":"長澤","familyNameLang":"ja"},{"familyName":"ナガサワ","familyNameLang":"ja-Kana"},{"familyName":"Nagasawa","familyNameLang":"en"}],"givenNames":[{"givenName":"和也","givenNameLang":"ja"},{"givenName":"カズヤ","givenNameLang":"ja-Kana"},{"givenName":"Kazuya","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"浦和, 茂彦","creatorNameLang":"ja"},{"creatorName":"ウラワ, シゲヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Urawa, Shigehiko","creatorNameLang":"en"}],"familyNames":[{"familyName":"浦和","familyNameLang":"ja"},{"familyName":"ウラワ","familyNameLang":"ja-Kana"},{"familyName":"Urawa","familyNameLang":"en"}],"givenNames":[{"givenName":"茂彦","givenNameLang":"ja"},{"givenName":"シゲヒコ","givenNameLang":"ja-Kana"},{"givenName":"Shigehiko","givenNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-04-05"}],"filename":"salmon-k-k_5-2.pdf","filesize":[{"value":"389KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2001604/files/salmon-k-k_5-2.pdf"},"version_id":"44ca8a5a-eb0c-4b67-b45e-cde555fbfdc0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"parasitic Copepoda; Salmincola californiensis; host range; masu salmon; prevalence; infection site; Hokkaido","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"別寒辺牛川のサクラマス幼魚におけるヤマメナガクビムシ(新称)Salmincola californiensisの寄生状況","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"別寒辺牛川のサクラマス幼魚におけるヤマメナガクビムシ(新称)Salmincola californiensisの寄生状況","subitem_title_language":"ja"},{"subitem_title":"Infection of Salmincola californiensis (Copepoda:Lernaeopodidae) on Juvenile Masu Salmon (Oncorhynchus masou) from a Stream in Hokkaido","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955843765"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-05"},"publish_date":"2024-04-05","publish_status":"0","recid":"2001604","relation_version_is_last":true,"title":["別寒辺牛川のサクラマス幼魚におけるヤマメナガクビムシ(新称)Salmincola californiensisの寄生状況"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-30T02:18:25.883719+00:00"}
