Zooplankton fecal pellets of at least 3 shapes, transparent oval objects, and one apparent appendicularian were observed to have been ingested. These types of objects are consistent with the hypothesis that leptocephali consume marine snow and discarded appendicularian houses, which both typically contain fecal pellets. Appendicularians have not been previously reported to be consumed by leptocephali, but the apparent presence of one in a muraenid intestine suggests that they may occasionally be consumed along with their houses. Chlopsid leptocephali in both regions were observed to have consumed large amounts of food material, which indicated that their short intestines are able to expand more than previously known. Due to net avoidance, most leptocephali are collected at night when feeding may be reduced, so visible food materials are rarely observed in their intestines at night. These photographs show some marine snow-related objects that are consumed by leptocephali more clearly than previous reports.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040663","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Atmosphere and Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学大気海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Atmosphere and Ocean Research Institute, The University of Tokyo"},{"subitem_text_value":"International Coastal Research Center, Atmosphere and Ocean Research Institute, The University of Tokyo"},{"subitem_text_value":"Research Center for Oceanography, Indonesian Institute of Sciences"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Miller, Michael J."}],"nameIdentifiers":[{"nameIdentifier":"93489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Otake, Tsuguo"}],"nameIdentifiers":[{"nameIdentifier":"93490","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoyama, Jun"}],"nameIdentifiers":[{"nameIdentifier":"93491","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wouthuyzen, Sam"}],"nameIdentifiers":[{"nameIdentifier":"93492","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suharti, Sasanti"}],"nameIdentifiers":[{"nameIdentifier":"93493","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sugeha, Hagi Y."}],"nameIdentifiers":[{"nameIdentifier":"93494","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Katsumi"}],"nameIdentifiers":[{"nameIdentifier":"93495","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-14"}],"displaytype":"detail","filename":"CMS350138.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS350138.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40672/files/CMS350138.pdf"},"version_id":"be86b5c0-8eb8-4f3f-a118-9e7e8bb24b9b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"leptocephali","subitem_subject_scheme":"Other"},{"subitem_subject":"anguilliformes","subitem_subject_scheme":"Other"},{"subitem_subject":"gut contents","subitem_subject_scheme":"Other"},{"subitem_subject":"feeding","subitem_subject_scheme":"Other"},{"subitem_subject":"appendicularians","subitem_subject_scheme":"Other"},{"subitem_subject":"North Equatorial Current","subitem_subject_scheme":"Other"},{"subitem_subject":"Tomini Bay","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":"Observations of gut contents of leptocephali in the North Equatorial Current and Tomini Bay, Indonesia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Observations of gut contents of leptocephali in the North Equatorial Current and Tomini Bay, Indonesia"}]},"item_type_id":"4","owner":"1","path":["7183","7181"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-25"},"publish_date":"2012-05-25","publish_status":"0","recid":"40672","relation_version_is_last":true,"title":["Observations of gut contents of leptocephali in the North Equatorial Current and Tomini Bay, Indonesia"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:13:49.123379+00:00"}
