D. brachyurum ahd D. longispina concentrate near the surface at night and in the 5-20m layer during the daytime. But, no clear diel vertical migration was observed in E, japonicus and M. lauckarti. The gammarid and shrimp are distributed in deep water of more than 30m depth in the daytime, but they come up to the surface layer at night. Their adults stay near the bottom during the daytime and migrate to the midwater at night. The fry and juveniles of R. brunneus and C. isaza also stayed on the bottom during the daitime and migrate to the midwater at night. The fry of  P. altivelis inhabiting near the bottom during the daytime show an upward migration to the midwater at night. The boundary for those vertical migrants exists in 10-20m layer, thermocline in summer, in Lake Biwa.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学水産学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-5772","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0023428X","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"663","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"びわ湖における動物プランクトンおよび仔稚魚の日周垂直移動"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"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":"Nagoshi, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN0023428X0000901.pdf","filesize":[{"value":"730.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN0023428X0000901.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5566/files/AN0023428X0000901.pdf"},"version_id":"6f5df639-1f75-4fea-b61f-30e21d223de9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"migration","subitem_subject_scheme":"Other"},{"subitem_subject":"ecology","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Diel vertical migration of zooplankters and fish larvae in lake Biwa","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Diel vertical migration of zooplankters and fish larvae in lake Biwa","subitem_title_language":"en"}]},"item_type_id":"4","owner":"13","path":["428"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-15"},"publish_date":"2007-06-15","publish_status":"0","recid":"5566","relation_version_is_last":true,"title":["Diel vertical migration of zooplankters and fish larvae in lake Biwa"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-11T06:07:40.917246+00:00"}
