The survey was conducted in an artificial clam nursery along the intertidal coastline of Lake Saroma, northeast Hokkaido. Experimental plots were covered with shells of the scallop Mizuhopecten yessoensis crushed into 2-5 mm, on July 2006 and June 2007, then the juvenile density, water flow and sediment characteristics were periodically investigated over 17 and 16 months, respectively. In the old plot, 1-year-old juveniles appeared in 3 months, and they increased significantly in 9 months. Their density reached 25.1 times that in the control plot in 17 months. In the new plot, the first recruitment of 1-year-old juveniles was observed after 1 year, and their density continued to increase until 16 months. Comparing the shear stress on the bottom with the critical threshold for juveniles, sediment and shells to start rolling, it was found that the juveniles being carried by flow were cumulatively caught in the small space between the shells. In addition, the sediment quality showed no harmful effect on the juveniles after the treatment.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"北海道サロマ湖アサリ増殖場に破砕したホタテガイ貝殻片を散布し，その後のアサリ稚貝の密度と流動環境を調べることにより，貝殻散布が稚貝の個体密度を増加させる効果について検討した。その結果，貝殻散布にはアサリ 1 歳貝を集積させる効果が認められた。また，この効果は，波・流れにより海底直上を移動させられる稚貝が貝殻片の間隙に捕捉される結果によるものと推察された。さらに，貝殻散布は，有機物量，硫化物量，餌料条件および地盤硬度からみた稚貝の生息環境に負の影響を与えないと考えられた。","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_87","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/2010834367","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":"櫻井, 泉","creatorNameLang":"ja"}],"familyNames":[{"familyName":"櫻井","familyNameLang":"ja"}],"givenNames":[{"givenName":"泉","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"福田, 裕毅","creatorNameLang":"ja"}],"familyNames":[{"familyName":"福田","familyNameLang":"ja"}],"givenNames":[{"givenName":"裕毅","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"前川, 公彦","creatorNameLang":"ja"}],"familyNames":[{"familyName":"前川","familyNameLang":"ja"}],"givenNames":[{"givenName":"公彦","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"山田, 俊郎","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山田","familyNameLang":"ja"}],"givenNames":[{"givenName":"俊郎","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"齊藤, 肇","creatorNameLang":"ja"}],"familyNames":[{"familyName":"齊藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"肇","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_87.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010518/files/fra_t_5_1_87.pdf"},"version_id":"16087e06-86c7-4938-a15e-3e317331607f"}]},"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":"ホタテガイ貝殻を活用したアサリ増殖場造成試験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホタテガイ貝殻を活用したアサリ増殖場造成試験","subitem_title_language":"ja"},{"subitem_title":"Field Experiment for Nursery Ground Creation of Short-neck Clam Ruditapes philippinarum Utilizing Scallop Shells as Substratum","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":"2010518","relation_version_is_last":true,"title":["ホタテガイ貝殻を活用したアサリ増殖場造成試験"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:35:27.084345+00:00"}
