NAGAI's equation, fN = M/1-exp(-M) is more approximate to the true value of f(F, M) than POPE's equation, fP =exp(M/2). The new algorithm to solve the catch equation was proposed. This method is the so-called successive substitution method, and it uses NAGAI's approximate value as the first approximation. It was clarified that in normal conditions, four or less times of iteration satisfies the convergence criteria, viz the error of the approximation is one percent or less. The applicable ranges of F and M for those approximate functions and the mentioned above were illustrated.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1)コホート解析に用いられる BARANOV の漁獲方程式について,POPE(1972)の関数f(F, M) = (F+M) {1-exp(-F))/F.[1-exp{-(F+M))]の近似式を数学的に検討した。2)永井(1980)の近似式 fN= M/1-exp(-M) が POPE の近似式 fP=exp(M/2) より真の関数値に近い。3)BARANOV の漁獲方程式の解法を検討し,永井の近似式による値を第1近似値として用いる逐次代入法を示した。実質的には4回以下の繰り返し計算で充分な精度が得られる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nnf_k_19_111","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/2010323094","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":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":[{"creatorNames":[{"creatorName":"Ishioka, Kiyohide","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"石岡, 清英","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"イシオカ, キヨヒデ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Ishioka","familyNameLang":"en"},{"familyName":"石岡","familyNameLang":"ja"},{"familyName":"イシオカ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kiyohide","givenNameLang":"en"},{"givenName":"清英","givenNameLang":"ja"},{"givenName":"キヨヒデ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3332","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishida, Tatsu","creatorNameLang":"en"},{"creatorName":"岸田, 達","creatorNameLang":"ja"},{"creatorName":"キシダ, タツ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kishida","familyNameLang":"en"},{"familyName":"岸田","familyNameLang":"ja"},{"familyName":"キシダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tatsu","givenNameLang":"en"},{"givenName":"達","givenNameLang":"ja"},{"givenName":"タツ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"476","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10416034","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10416034"}]}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"コホート解析に用いる漁獲方程式の解法とその精度の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"コホート解析に用いる漁獲方程式の解法とその精度の検討","subitem_title_language":"ja"},{"subitem_title":"Studies on the Algorithm for Solving the Catch Equation and Its Accuracy","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003265","relation_version_is_last":true,"title":["コホート解析に用いる漁獲方程式の解法とその精度の検討"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-12-26T01:21:43.880354+00:00"}
