To reveal the ages and early life histories of this species, the otolith microstructure of the leptocephali collected near the Sulawesi Island and off Sumatra of Indonesia were examined. The otolith microstructure of the A. interioris leptocephali was similar to other anguillid species and showed narrow increment widths (0.49-0.58μm) near the core that increased (1.14-1.34μm) before decreasing again until the otolith edge (0.51-0.83μm), except in the smallest specimen (12.4mm TL) collected off Sumatra, which had no peak. The range of Sr: Ca ratios in their otoliths were 8.37 to 14.01. Their ages were 19d for the smallest specimen from off Sumatra, 85d for the specimen (48.9mm TL) from Tomini Bay, and 85 to 94d for the three specimens (43.4-46.5mm TL) from the Molucca Sea. The overall growth rate of the leptocephali was 0.48mm/d, and this value was intermediate compared with the growth rates of the other anguillid species. The age of the smallest A. interioris leptocephalus collected off Sumatra and the geographic patterns of currents in the regions, suggest that it was spawned in the Indian Ocean and that it may belong to a different population than the New Guinea population.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040739","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, 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":"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":"Kuroki, Mari"}],"nameIdentifiers":[{"nameIdentifier":"139419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoyama, Jun"}],"nameIdentifiers":[{"nameIdentifier":"139420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wouthuyzen, Sam"}],"nameIdentifiers":[{"nameIdentifier":"139421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sumardhiharga, Kurunaen Ono"}],"nameIdentifiers":[{"nameIdentifier":"139422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miller, Michael J."}],"nameIdentifiers":[{"nameIdentifier":"139423","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minagawa, Gen"}],"nameIdentifiers":[{"nameIdentifier":"139424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Katsumi"}],"nameIdentifiers":[{"nameIdentifier":"139425","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":"2017-06-27"}],"displaytype":"detail","filename":"KJ00004354647.pdf","filesize":[{"value":"625.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004354647.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40748/files/KJ00004354647.pdf"},"version_id":"5f428ee0-d585-43bf-bf88-81619685c7d6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"eel","subitem_subject_scheme":"Other"},{"subitem_subject":"Anguilla interioris","subitem_subject_scheme":"Other"},{"subitem_subject":"leptocephali","subitem_subject_scheme":"Other"},{"subitem_subject":"otolith","subitem_subject_scheme":"Other"},{"subitem_subject":"age","subitem_subject_scheme":"Other"},{"subitem_subject":"growth","subitem_subject_scheme":"Other"},{"subitem_subject":"mtDNA","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":"Age and growth of Anguilla interioris leptocephali collected in Indonesian waters","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Age and growth of Anguilla interioris leptocephali collected in Indonesian waters"}]},"item_type_id":"4","owner":"1","path":["7203","7201"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-05"},"publish_date":"2007-04-05","publish_status":"0","recid":"40748","relation_version_is_last":true,"title":["Age and growth of Anguilla interioris leptocephali collected in Indonesian waters"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:23.752099+00:00"}
