Contrary to the expectations, it resulted in the complete removal of separators in 2006 because fishers considered that separators had contributed to the price collapses in the 2000s. The intent of this paper is to investigate the effects of separators on both the fishery economy and stock of Pacific saury through simulating population and economic models under a single framework. For this purpose, we specifically developed (i) an age-structured population dynamics model with stochasticity, and (ii) an economic model spanning both price and inventory dynamics with stochasticity, in which each set of model parameters were estimated based on time series data. In ten year simulation, we set the harvest quota as constant covering from 20 to 400 thousand tons, and the effects of separators were incorporated by controlling the catchability of 0 year old fish. We have identified that separators increase the expected yield and decrease the deficit risk when the annual harvest is set smaller than 160 thousand tons. Otherwise, they decrease the expected yield and increase the deficit risk.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"オヤマダ, セイイチ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ウエノ, ヤスヒロ"}]},{"nameIdentifiers":[{}],"names":[{"name":"マキノ, ミツタク"}]},{"nameIdentifiers":[{}],"names":[{"name":"コタニ, コウジ"}]},{"nameIdentifiers":[{}],"names":[{"name":"マツダ, ヒロユキ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12562-008-0046-0","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10993718","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09199268","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"},{"subitem_text_value":"Hachinohe Branch, Tohoku National Fisheries Research Institute"},{"subitem_text_value":"Fisheries Research Agency"},{"subitem_text_value":"Graduate School of International Relations, International University of Japan"},{"subitem_text_value":"Graduate School of Environment and Information Sciences, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Oyamada, Seiichi"}],"nameIdentifiers":[{"nameIdentifier":"22167","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueno, Yasuhiro"}],"nameIdentifiers":[{"nameIdentifier":"22168","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makino, Mitsutaku"}],"nameIdentifiers":[{"nameIdentifier":"22169","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kotani, Koji"}],"nameIdentifiers":[{"nameIdentifier":"22170","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuda, Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"22171","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-16"}],"displaytype":"detail","filename":"Matsuda05.pdf","filesize":[{"value":"238.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Matsuda05.pdf","url":"https://ynu.repo.nii.ac.jp/record/4789/files/Matsuda05.pdf"},"version_id":"3bdada3c-41b1-48af-b549-8d5edb3f15ce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fisheries management","subitem_subject_scheme":"Other"},{"subitem_subject":"bioeconomic simulation","subitem_subject_scheme":"Other"},{"subitem_subject":"risk analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Pacific saury","subitem_subject_scheme":"Other"},{"subitem_subject":"discarding","subitem_subject_scheme":"Other"},{"subitem_subject":"size separators","subitem_subject_scheme":"Other"},{"subitem_subject":"price","subitem_subject_scheme":"Other"},{"subitem_subject":"population dynamics","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":"Bioeconomic assessment of size separators in Pacific saury fishery : bioeconomic assessment of size separators","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Bioeconomic assessment of size separators in Pacific saury fishery : bioeconomic assessment of size separators"}]},"item_type_id":"2","owner":"3","path":["501"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-26"},"publish_date":"2012-03-26","publish_status":"0","recid":"4789","relation_version_is_last":true,"title":["Bioeconomic assessment of size separators in Pacific saury fishery : bioeconomic assessment of size separators"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:20:18.529905+00:00"}
