The levels of nine trace metals in liver and muscle tissues were determined. The results indicated that the levels of Zn, which is an essential metal, in the tissues elevate with the gonadal maturation in both species. The other essential metals such as Cr, Co, Mn and Cu tended to be accumulated at higher levels in silver eels than in yellow eels; however, different levels of metal accumulations were observed between the species. Nonessential metals such as Cd and Pb in tissues exhibited no significant difference between the two stages of eels. Although the two species resided in the same river, the Hg levels in A. marmorata were found to be higher than that in A. bicolor. The results suggest the difference of metal accumulations between the eel species is dependent on the preferred food items and the maturity stages rather than ambient environment.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Proceedings of the Horiba International Conference \"New Direction of Ocean Research in the Western Pacific\" : Past, Present and Future of UNESCO/IOC/WESTPAC Activity for 50 years and the JSPS Project \"Coastal Marine Science\"","subitem_description_type":"Other"},{"subitem_description":"Section I: Research Articles/Pollution","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040646","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":"International Coastal Research Center, Ocean Research Institute, The University of Tokyo"},{"subitem_text_value":"Institute of Marine Environment and Resources"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Le, Quang Dung"}],"nameIdentifiers":[{"nameIdentifier":"93437","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nguyen, Duc Cu"}],"nameIdentifiers":[{"nameIdentifier":"93438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nguyen, Duc Toan"}],"nameIdentifiers":[{"nameIdentifier":"93439","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":"CMS350121.pdf","filesize":[{"value":"582.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CMS350121.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40655/files/CMS350121.pdf"},"version_id":"a082ee9b-e2f4-4994-9d01-7f247aa84302"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"anguillid eels","subitem_subject_scheme":"Other"},{"subitem_subject":"maturation","subitem_subject_scheme":"Other"},{"subitem_subject":"metal accumulation","subitem_subject_scheme":"Other"},{"subitem_subject":"energy reserve","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":"Trace metal contents of tropical anguillid eels in Vietnam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trace metal contents of tropical anguillid eels in Vietnam"}]},"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":"40655","relation_version_is_last":true,"title":["Trace metal contents of tropical anguillid eels in Vietnam"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:13.181722+00:00"}
