The length and weight of catch were measured and the number and weight of discards were calculated. The results showed that the percentage of the catch of marketable spedes in weight was an average of 67.4 percent of the total amount of catch and the individuals of discard size in marketable species occupies about 30 percent of the catch weight in that. The discard percentage of marketable species to the total discards in weight was 39.3 percent on the average. Among the discarded fish, frog flounder Pleuronichthys cornutus, the target species was yielded significantly with the average of 38.5 percent of total discard weight in marketable species. The percentage of the discard number to the catch number of frog flounder was much higher in the summer than in the winter with an average of 76.1 percent.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本水産学会誌 = Bulletin of the Japanese Society of Scientific Fisheries. 2004, 70(5), p.738-744","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"70017","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hirai, Yoshio"}]},{"nameIdentifiers":[{"nameIdentifier":"70018","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishinokubi, Hideyuki"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人日本水産学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"社団法人日本水産学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00193422","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00215392","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"平井, 良夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西ノ首, 英之"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"suisan70_5_738_744.pdf","filesize":[{"value":"618.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan70_5_738_744.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/17720/files/suisan70_5_738_744.pdf"},"version_id":"ba960034-9445-4ea6-a204-d0391c0905ae"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"有明海","subitem_subject_scheme":"Other"},{"subitem_subject":"小型底曳網","subitem_subject_scheme":"Other"},{"subitem_subject":"有用種","subitem_subject_scheme":"Other"},{"subitem_subject":"混獲","subitem_subject_scheme":"Other"},{"subitem_subject":"投棄","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","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"有明海小型底曳網漁業における有用種の混獲投棄の実態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有明海小型底曳網漁業における有用種の混獲投棄の実態"}]},"item_type_id":"2","owner":"2","path":["51"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-14"},"publish_date":"2009-04-14","publish_status":"0","recid":"17720","relation_version_is_last":true,"title":["有明海小型底曳網漁業における有用種の混獲投棄の実態"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:25:36.065158+00:00"}
