The early life histories of Tokachi River late-migrating chum salmon areestimated based on microstructural analysis of thermally marked otoliths from reca-ptured fish. A revised model is presented that reveals the optimal timing of and sizeat release of chum salmon juveniles to be dependent upon their size at sea entry andsea surface temperature (SST) near Tokachi River mouth. Juvenile salmon areassumed to grow at a fixed rate after sea entry and to reach a target fork length uponarrival in Kombumori waters when SST conditions are within a specific optimal range.However, because of annual variation in SST, the size at and timing of juvenile chumsalmon sea entry following their release from hatcheries represents a moving target,which flexible hatchery release practices are required to meet. Return rates of adultchum salmon to Tokachi River correlate positively with the number of days elapsedbetween the period when SST is suitable near the river mouth where they enter thesea, and SST conditions in Kombumori waters, which suggests that in years whenSST increases rapidly the survival of salmon tends to decline. Windows of optimaltimes of and sizes at release are proposed for juvenile chum salmon to improve theirsurvival and hatchery success.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley","subitem_publisher_language":"en"},{"subitem_publisher":"The Japanese Society of Fisheries Oceanography","subitem_publisher_language":"en"},{"subitem_publisher":"水産海洋学会","subitem_publisher_language":"ja"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1111/fog.12585","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10057755","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":"en","subitem_relation_name_text":"WILEY : Online Library"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://onlinelibrary.wiley.com/doi/full/10.1111/fog.12585","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":"1365-2419","subitem_source_identifier_type":"EISSN"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1054-6006","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_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"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":[{"affiliationNames":[{"affiliationName":"水産研究・教育機構","affiliationNameLang":"ja"},{"affiliationName":"Japan Fisheries Research and Education Agency","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Saito, Toshihiko","creatorNameLang":"en"},{"creatorName":"斎藤, 寿彦","creatorNameLang":"ja"},{"creatorName":"サイトウ, トシヒコ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Saito","familyNameLang":"en"},{"familyName":"斎藤","familyNameLang":"ja"},{"familyName":"サイトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toshihiko","givenNameLang":"en"},{"givenName":"寿彦","givenNameLang":"ja"},{"givenName":"トシヒコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1086","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30425459","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30425459"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-06-16"}],"filename":"Saito Optimum timing and size at release of chum salmon  Improving survival by modifying.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/141/files/Saito Optimum timing and size at release of chum salmon  Improving survival by modifying.pdf"},"version_id":"12114986-f4a2-418f-8c9d-daaaf86d9085"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"chum salmon; hatchery; juvenile; migration; otolith; recruitment; releas","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Optimum timing and size at release of chum salmon: Improving survival by modifying hatchery practices","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Optimum timing and size at release of chum salmon: Improving survival by modifying hatchery practices","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["15"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-01-27"},"publish_date":"2023-01-27","publish_status":"0","recid":"141","relation_version_is_last":true,"title":["Optimum timing and size at release of chum salmon: Improving survival by modifying hatchery practices"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-23T00:19:34.014019+00:00"}
