In this paper, OY is the maximum static net economic yield from multiple stocks that are simultaneously exploited by various fisheries. \nDynamics of the size of the whole stocks are approximated using a discrete surplus production model that is expressed by an algebraic function of the depletion level of the whole stocks. Estimates of biological parameters in the model and depletion levels of the whole stocks over the last several decades are available from a previous study and fish price and cost parameters were estimated using catch and economic statistics for 1973-2013. \nEstimates of OY calculated using those parameter values increased from 40 billion yen in 1973 to 196 billion yen in 2013. The level of fishing coefficient for realizing the OY in 2013 was 84% of the actual level in 2013. Application of the results to stock management and issues to be resolved in the near future are discussed."}]},"item_3_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"J-STAGE 早期公開版 (2019)あり : https://www.jstage.jst.go.jp/article/suisan/advpub/0/advpub_18-00033/_article/-char/ja"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本水産学会"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2331/suisan.18-00033","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2331/suisan.18-00033","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"日本水産学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jsfs.jp/","subitem_relation_type_select":"URI"}}]},"item_3_relation_28":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"130007622907","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-5392","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00193422","subitem_source_identifier_type":"NCID"}]},"item_3_text_61":{"attribute_name":"タイトル（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ニッポン ノ エンガン ・ オキアイ スイイキ ニ オケル ソコウオ ギョギョウ ノ サイテキ セイサンリョウ ニ ツイテ"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 栄次"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"沿岸","subitem_subject_scheme":"Other"},{"subitem_subject":"最大純経済生産量","subitem_subject_scheme":"Other"},{"subitem_subject":"最適生産量","subitem_subject_scheme":"Other"},{"subitem_subject":"底魚","subitem_subject_scheme":"Other"},{"subitem_subject":"適正規模","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"}]},"item_title":"日本の沿岸・沖合水域における底魚漁業の最適生産量について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本の沿岸・沖合水域における底魚漁業の最適生産量について"},{"subitem_title":"Optimum yield of demersal fisheries in Japan's coastal and offshore waters","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["318","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-10"},"publish_date":"2022-05-10","publish_status":"0","recid":"2448","relation_version_is_last":true,"title":["日本の沿岸・沖合水域における底魚漁業の最適生産量について"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-25T10:31:18.116740+00:00"}
