Planktonic larvae of C. japonica passed through the trochophore and D-shaped larval stages (the early stage of veliger larvae), but lacked umbo larvae (the latter stage of veliger larvae), with the result that the late-stage D-shaped larvae with a developed foot settled and metamorphosed on the bottom and walls of culture vessels. To aid in the identification of the larvae of C. japonica in plankton samples and their post-larvae in benthos samples, larval and post-larval shell morphology of the clam is described and compared with that of the other bivalves dominant in Japanese estuarine waters.","subitem_description_type":"Abstract"},{"subitem_description":"汽水性二枚貝ヤマトシジミは本邦における水産重要種である。本研究では,ヤマトシジミの人工産卵誘発によって得られた受精卵を15℃,20℃,25℃の温度条件で18日間飼育し,浮遊幼生,変態期幼坐,着底椎貝の成長と形態を観察した。ヤマトシジミの受精卵はトロコフォア幼生を経てD型幼生に成長するが,この幼生は後期ベリジャー幼生期にあたる殻頂期幼生にはならず,D型幼生の後期に足を発達させ,変態期幼生となって着底する。着底直後の稚貝の殻はD型であり,これはやがて殻頂をもつ殻に変わる。最も成長のよかった25℃の温度条件下では,受精後12日に平均殻長195μmに達し,ほとんどの個体が着底した。一方,15℃の温度条件下では実験終了まで着底個体は観察されなかった。本研究では野外の浮遊幼生や稚貝の試料の同定のために,ヤマトシジミの浮遊幼生と着底稚貝の形態を記載し,これらと本州河口干潟に優占する二枚貝類幼生(アサリ,ホトトギスガイ,イソシジミ,シオフキガイ,ハマグリ)の形態との比較をおこなった。浮遊幼生はD型幼生では大きさ以外の識別点は乏しい。それに対して着底稚貝では,ヤマトシジミの殻の周縁に形成される放射肋により,他の種とは明確に識別できる。","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本貝類学会"}]},"item_10001_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110004848853"}]}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは学協会の許諾に基づき掲載しています / (c) Malacological Society of Japan"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11565254","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13482955","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_25":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_value":"ヤマトシジミ幼生の成長および共存する二枚貝幼生との形態比較"}]},"item_10001_text_70":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Journal Article / 学術雑誌論文"}]},"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kimura, Taeko","creatorNameLang":"en"},{"creatorName":"木村, 妙子","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"Soutome, Yurina","creatorNameLang":"en"},{"creatorName":"五月女, 祐里奈","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"Sekiguchi, Hideo","creatorNameLang":"en"},{"creatorName":"関口, 秀夫","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"50A16351.pdf","filesize":[{"value":"5.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"50A16351.pdf","url":"https://mie-u.repo.nii.ac.jp/record/10315/files/50A16351.pdf"},"version_id":"e70f1194-a740-4783-97ad-a26832c44373"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Corbicula","subitem_subject_scheme":"Other"},{"subitem_subject":"morphology","subitem_subject_scheme":"Other"},{"subitem_subject":"larva","subitem_subject_scheme":"Other"},{"subitem_subject":"post-larva","subitem_subject_scheme":"Other"},{"subitem_subject":"development","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Larval Development of the Brackish Water Clam Corbicula japonica (Bivalvia: Corbiculidae), with Special Reference to Morphological Comparison with Concurrent Tidal Flat Bivalves","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Larval Development of the Brackish Water Clam Corbicula japonica (Bivalvia: Corbiculidae), with Special Reference to Morphological Comparison with Concurrent Tidal Flat Bivalves","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["685"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-11-14"},"publish_date":"2013-11-14","publish_status":"0","recid":"10315","relation_version_is_last":true,"title":["Larval Development of the Brackish Water Clam Corbicula japonica (Bivalvia: Corbiculidae), with Special Reference to Morphological Comparison with Concurrent Tidal Flat Bivalves"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-10-17T02:16:07.309595+00:00"}
