The results obtained are as follows: 1. Even when the trawl was rigged with cone and suction-hose little deformation in trawls was noted. Decreasing percentage in the areas of net moth, horizontal section, and vertical section was observed to be only a little. 2. Concerning the flow-speed, it was generally lower inside the net, than it was outside the net, but an acceleration in flow-speed was recognized in some case. 3．In case of thin twined webbing, net-performance was lower than in the thick one, especially when the flow-speed was low, because there was less extension than in the latter case. Hence the necessity of choosing the twine-size and mesh-size most appropriate to the towing-speed.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"660","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"今井, 健彦","creatorNameLang":"ja"},{"creatorName":"IMAI, Takehiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"11765","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020041709","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN00040498_v23_p45-55.pdf","filesize":[{"value":"4.4 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040498_v23_p45-55.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10814/files/AN00040498_v23_p45-55.pdf"},"version_id":"136d1bec-aa85-4dfc-adfd-deaef266eeb8"}]},"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":"中層曳網の研究I : 網中の流速分布と網成りについて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中層曳網の研究I : 網中の流速分布と網成りについて","subitem_title_language":"ja"},{"subitem_title":"Studies on the Midwater Trawl I : Distribution of flow-speed inside the Net and Performance of the Net-shape","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["40","4834"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-17"},"publish_date":"2015-06-17","publish_status":"0","recid":"10814","relation_version_is_last":true,"title":["中層曳網の研究I : 網中の流速分布と網成りについて"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-30T01:13:14.814708+00:00"}
