Most of the production of this clam is from the wild catch, and the culture production in tidal flats accounts for only 6% to 7% of the total production. The recently established suspended culture of asari clam has not been widely used in Japan or elsewhere. Considering the sharp decline of the wild catch in Japan since the 1980s, it is worthwhile attempting to expand culture production, especially in suspended culture. Clam culture requires a seed supply and appropriate facilities and materials. This paper discusses techniques for natural seed collection using mesh bags and the materials and locations required for suspended culture. To disseminate the suspended culture, the culture procedure should be designed to suit the environmental conditions and ensure economic profitability, which depends on the unit price and the cost of the seed and the materials. It is essential to increase the added value, emphasizing the localness of the cultured clams by utilizing natural seeds collected in local areas. Pre-culture in tidal flats in combination with subsequent suspended culture may be useful to increase the efficacy of culture production.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"アサリはほとんどが天然資源の漁獲に依存し，干潟での養殖は全生産量の 6～7％を占めるにすぎない。近年，アサリの垂下養殖が着目されているが，まだ普及していない。しかし，1980 年代以降におけるアサリ漁獲量の急激な減少により垂下養殖を含めたアサリ養殖の意義は大きい。アサリの養殖には種苗の確保と適切な施設や器材が必要であるので，本論では網袋を用いたアサリ天然採苗および垂下養殖に適した器材や場の選定について論じた。垂下養殖の普及に向けては，環境条件に合う養殖方法の選択と収益性の確保が必要条件である。そのためには，地元産種苗を用いるなど付加価値の向上および干潟養殖と垂下養殖の組合せなど生産の効率化が必須である。","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_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/2010912402","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":"日向野, 純也","creatorNameLang":"ja"}],"familyNames":[{"familyName":"日向野","familyNameLang":"ja"}],"givenNames":[{"givenName":"純也","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"浅尾, 大輔","creatorNameLang":"ja"}],"familyNames":[{"familyName":"浅尾","familyNameLang":"ja"}],"givenNames":[{"givenName":"大輔","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_87.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010589/files/fra_t_9_3_87.pdf"},"version_id":"d11546a8-9310-49da-9c72-a955dc6bfeda"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アサリ; 種苗; 垂下養殖; 天然採苗","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":"アサリ垂下養殖の意義と普及に向けた課題","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アサリ垂下養殖の意義と普及に向けた課題","subitem_title_language":"ja"},{"subitem_title":"Significance of the suspended culture of asari clam Ruditapes philippinarum and obstacles to increasing its use","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":"2010589","relation_version_is_last":true,"title":["アサリ垂下養殖の意義と普及に向けた課題"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:40:15.995748+00:00"}
