The enzymatic activity of the clams fed Pavlva lutheri increased rapidly on the third day after the experiment started. The specific enzymatic activity became about eight times greater than that of the unfed controls on the fifth day. The cellobiosidase activity of the clam juveniles collected from some tidal flat areas with different environmental conditions was also measured. The enzymatic activity of the in situ clams varied greatly. No obvious seasonal variation was observed in the clams collected from a tidal flat area for two years. The mean enzymatic activity tended to be high when the chlorophyll a or protein content was high in the sediment. The enzymatic activity of the clams collected from a subtidal area was greater than those from intertidal areas. Moreover, the enzymatic activity of the clams collected from an area covered densely with Asian date mussel Musculista senhousia mat was lower than those from the neighboring sandy area. These results suggest that the enzymatic activity reflected the availability of food in the clam habitats.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"アサリ稚貝の摂餌状況と消化酵素活性との関係を明らかにすることを目的とし，稚貝のセロビオシダーゼ活性を測定した。人工採苗した稚貝では 5 日間の給餌飼育試験で本酵素比活性が絶食区に比べて 7 ～ 9 倍高くなった。野外で採取した稚貝では，本酵素活性が個体毎に大きく異なったが，底土中のクロロフィル a やタンパク質の含有量が多い時に酵素活性が高い傾向がみられた。また潮間帯と潮下帯，あるいはホトトギスガイのマット内外から採取した稚貝では本酵素活性に差が認められ，アサリ稚貝の消化酵素活性が生息環境により異なることが示された。","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_49","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/2010834363","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":"坂見, 知子","creatorNameLang":"ja"}],"familyNames":[{"familyName":"坂見","familyNameLang":"ja"}],"givenNames":[{"givenName":"知子","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"日向野, 純也","creatorNameLang":"ja"}],"familyNames":[{"familyName":"日向野","familyNameLang":"ja"}],"givenNames":[{"givenName":"純也","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_49.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010514/files/fra_t_5_1_49.pdf"},"version_id":"564e910a-5888-4609-b5e7-7fafb2e6e0b9"}]},"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":"消化酵素活性によるアサリ摂餌状況評価の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"消化酵素活性によるアサリ摂餌状況評価の試み","subitem_title_language":"ja"},{"subitem_title":"An Attempt to Assess the Feeding Activity of Short-neck Clam Ruditapes philippinarum Juveniles by a Digestive Enzyme Cellobiosidase Activity","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":"2010514","relation_version_is_last":true,"title":["消化酵素活性によるアサリ摂餌状況評価の試み"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:35:13.358467+00:00"}
