Eight males were mated with 20 females using a hierarchical design. Fish from the 20 crosses were raised separately to an average standard length of 11.5～13.0cm and average body weight of 25.9～37.3g. Five hundred and ninety-three fish were then individually PIT tagged and reared in a pond for the growth experiment through 90 days. In this study, one fish died, and 22 fish were not able to be identified. These 22 fish included fish that had lost the tag and also fish that had ingested lost tags. However, information concerned with the growth rate was obtained from 570 fish. Mean values for the ratio of the final to initial body length and body weight were 1.215 and 1.686, respectively. From analysis of variance of half-sib, heritabilities based on the sire components for the ratio of the final to initial body length and body weight were estimated to be 0.242 and 0.261, respectively. These values indicate that individual selection may be effective to improve growth of Nikko strain rainbow trout to some degree. The method of individual identification by PIT tag is considered to be effective for such genetic studies based on a hierarchical design, because all the examination fish can be reared on one pond after installing the tag and the individual number can be identified from the outside by the detecter without damaging fish.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"日光系ニジマス雄親魚８尾と雌親魚20尾による20組の枝分かれ交配を行い，平均約31ｇまで各交配組毎に飼育し，腹腔内に PIT tag を装着させて全個体を同一の飼育池に収容して90日間の飼育試験を行った。成長率は体長で1.215，体重で1.686と小さかったが，三元配置の分散分析法の雄親魚成分の分散から，体長の成長率の遺伝率0.239，体重の成長率の遺伝率0.261を推定した。また，両形質間の遺伝相関は0.983と極めて高い正の相関が推定された。これらの結果から，日光系ニジマスの成長の改良には個体選択と家系選択とを組み合わせることが効果的であること，体長への選択は体重へも同程度の選択反応が期待できることが示唆された。また，PIT tag による個体識別法は枝分かれ交配による遺伝研究には有効であることが明らかとなった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_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"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_16_1","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_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/2010730031","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":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Sato, Ryozo","creatorNameLang":"en"},{"creatorName":"佐藤, 良三","creatorNameLang":"ja"},{"creatorName":"サトウ, リョウゾウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Sato","familyNameLang":"en"},{"familyName":"佐藤","familyNameLang":"ja"},{"familyName":"サトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Ryozo","givenNameLang":"en"},{"givenName":"良三","givenNameLang":"ja"},{"givenName":"リョウゾウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2791","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Azuma, Teruo","creatorNameLang":"en"},{"creatorName":"東, 照雄","creatorNameLang":"ja"},{"creatorName":"アズマ, テルオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Azuma","familyNameLang":"en"},{"familyName":"東","familyNameLang":"ja"},{"familyName":"アズマ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Teruo","givenNameLang":"en"},{"givenName":"照雄","givenNameLang":"ja"},{"givenName":"テルオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2056","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90360768","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90360768"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Muto, Koji","creatorNameLang":"en"},{"creatorName":"武藤, 光司","creatorNameLang":"ja"},{"creatorName":"ムトウ, コウジ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Muto","familyNameLang":"en"},{"familyName":"武藤","familyNameLang":"ja"},{"familyName":"ムトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Koji","givenNameLang":"en"},{"givenName":"光司","givenNameLang":"ja"},{"givenName":"コウジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"636","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_16_1.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010823/files/fra_k_16_1.pdf"},"version_id":"be5b323b-0e35-45bd-9850-57a113235cf6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rainbow trout;
