Clams (3.7–6.4 mm in shell length) were placed in small plastic containers with sand substrate. The containers were covered with or without a net (mesh size of 2, 7, or 14 mm) and suspended at three positions (periphery, middle, and center) in an experimental tank with circular water flow for 43 to 57 days. Survival rates of the clams were over 97% in all containers during the experimental period. Growth rates of the clams were higher at the periphery (higher flow rate) than at the center of the tank (lower flow rate). Clams also grew slower with nets with a smaller mesh size. These differences in growth rate might be attributable to differences in the extent of food supply to the clams. Higher water flow may increase the rate at which the suspension-feeding clams encounter food particles. Being covered with a net with a small mesh size may reduce water exchange between the inside and the outside of the container, resulting in a reduced food supply.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"アサリを効率的に垂下養殖するための環境条件や養殖資材について検討するために，陸上水槽において飼育試験を行った。縁辺部から自然海水を注水して回転流を生じさせた大型円形水槽内に，アサリと砂を入れた小型容器を垂下して，43～57 日後の生残と成長を調べた。試験期間中のアサリ稚貝の生存率は高かった。また，アサリ稚貝の成長は流速の速い水槽縁辺部に垂下した容器で大きく，流速の遅い水槽中心部に垂下した容器では小さかった。垂下容器に取り付ける網蓋の目合を変えた試験では，網蓋の目合が小さいほど，アサリ稚貝の成長が抑制された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research and Education 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_9_3_147","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/2010912409","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":"伊藤, 篤","creatorNameLang":"ja"}],"familyNames":[{"familyName":"伊藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"篤","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"西本, 篤史","creatorNameLang":"ja"}],"familyNames":[{"familyName":"西本","familyNameLang":"ja"}],"givenNames":[{"givenName":"篤史","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小島, 大輔","creatorNameLang":"ja"}],"familyNames":[{"familyName":"小島","familyNameLang":"ja"}],"givenNames":[{"givenName":"大輔","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"山崎, 英樹","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山崎","familyNameLang":"ja"}],"givenNames":[{"givenName":"英樹","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"兼松, 正衛","creatorNameLang":"ja"}],"familyNames":[{"familyName":"兼松","familyNameLang":"ja"}],"givenNames":[{"givenName":"正衛","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"崎山, 一孝","creatorNameLang":"ja"}],"familyNames":[{"familyName":"崎山","familyNameLang":"ja"}],"givenNames":[{"givenName":"一孝","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_9_3_147.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010596/files/fra_t_9_3_147.pdf"},"version_id":"58db6793-6997-4a55-92df-8c6bbbb03227"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アサリ; 垂下養殖; 成長; 流速","subitem_subject_language":"ja","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":"流速と網蓋の目合が垂下飼育アサリの成長に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"流速と網蓋の目合が垂下飼育アサリの成長に及ぼす影響","subitem_title_language":"ja"},{"subitem_title":"The effects of water flow and mesh size of the covering net on the growth of asari clam Ruditapes philippinarum suspended in a tank.","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085691519"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010596","relation_version_is_last":true,"title":["流速と網蓋の目合が垂下飼育アサリの成長に及ぼす影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:40:44.666435+00:00"}
