Therefore, 14 small-scale trawl fishing sessions in the Ariake Sea were carried out to investigate this quantitatively. The length and weight of catch were measured and the number and weight of discards were calculated. The results showed that the total amount of catch was much greater in the summer than in the winter. The discard percentage based on the total catch in weight ranged from 36-67% with an average of 53%. An average of 93% of the total discards in weight was bony fish and cartilaginous fish. The main discarded species in unmarketable fishes were thornback ray Platyrhina sinensts and genko sole Cynoglossus interruptus. The main discarded species in marketable fishes was frog flounder Plcuronickthys cornutus, which is the target fish of small-scale trawl fishery in the Ariake Sea.","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. 2003, 69(3), p.330-336","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"69991","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hirai, Yoshio"}]},{"nameIdentifiers":[{"nameIdentifier":"69992","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":"suisan69_3_330_336.pdf","filesize":[{"value":"812.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan69_3_330_336.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/17710/files/suisan69_3_330_336.pdf"},"version_id":"2adccb6a-08c2-473b-8c7b-1b1becd96488"}]},"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":"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混獲物の投棄の実態","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混獲物の投棄の実態"}]},"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":"17710","relation_version_is_last":true,"title":["有明海小型底曳網漁業における混獲物の投棄の実態"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:26:10.101277+00:00"}
