The bulk of the gravel was quickly removed from the experimental plot by waves and covered with sediment, while less gravel was moved in another plot shaded behind the fence. Factorial analyses demonstrated that the shading treatment with the fence had significantly positive effects on juvenile abundance, while the capping treatment with gravel had limited effects. The critical shear stress of the substrate decreased as the gravel within it was removed and/or buried followed by a decline in the median diameter of the substrate. In the plot shaded by the fence, the shear stress less frequently exceeded the critical level of gravel and juveniles than in the plot without the fence. In practice, the settlement and survival of juveniles would be improved by installing fences in the open tidal flat.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"アサリ稚貝の着底と生残に砕石と支柱柵が与える水力学的効果を比較するため、有明海の砂質干潟で 2 年間実験を行った。砕石で被覆した試験区では砕石の顕著な移動と埋没がみられ、支柱柵を併設した区では砕石の移動が少なかった。因子分析では、稚貝数に対する砕石の効果が有意になることは一時的で、むしろ支柱柵の効果が有意であった。また、砕石が移動・埋没すると、その場の中央粒径が小さくなり、底質の限界せん断応力が低下した。一方、支柱柵を併設すると、実際のせん断応力が砕石や稚貝の限界せん断応力を超える頻度が減少した。実用的には、干潟に支柱柵を設置すると稚貝の定着が促進されることが期待される。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_5_1_75","subitem_relation_type_select":"Local"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引（AgriKnowledge）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010834366","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"生嶋, 登","creatorNameLang":"ja"}],"familyNames":[{"familyName":"生嶋","familyNameLang":"ja"}],"givenNames":[{"givenName":"登","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"齊藤, 肇","creatorNameLang":"ja"}],"familyNames":[{"familyName":"齊藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"肇","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"那須, 博史","creatorNameLang":"ja"}],"familyNames":[{"familyName":"那須","familyNameLang":"ja"}],"givenNames":[{"givenName":"博史","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_5_1_75.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010517/files/fra_t_5_1_75.pdf"},"version_id":"c9e77f9a-cf24-4ed8-8e9d-9d27cea36f6f"}]},"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":"アサリ稚貝の着底と生残を促進するための砕石散布と支柱柵設置の水力学的効果に関する干潟での野外実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アサリ稚貝の着底と生残を促進するための砕石散布と支柱柵設置の水力学的効果に関する干潟での野外実験","subitem_title_language":"ja"},{"subitem_title":"A Field Experiment in a Tidal Flat on Hydrodynamic Effects of Scattering Artificial Gravels and Setting Up Fences That Enhance Settlement and Survival of Juvenile Short-neck Clam Ruditarpes philippinarum","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085692591"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010517","relation_version_is_last":true,"title":["アサリ稚貝の着底と生残を促進するための砕石散布と支柱柵設置の水力学的効果に関する干潟での野外実験"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:35:22.204745+00:00"}
