Using callianassid shrimp Nihonotrypaea harmandi larvae collected from a 65 m deep inner-shelf location off mid-western Kyushu, Japan, between June and August 2012 and 2013 and mass-reared in the laboratory, a phytoplankton-based diet through larval development (zoeae I?VI to decapodid) was demonstrated. When the pure-cultured diatom Chaetoceros gracilis was fed to zoeae, survival rate to decapodids was 3.4 to 3.9% in 26 to 40 d at 22°C, which was comparable to previous rearing results for zoeae fed microzooplankton. Trophic enrichment factors (TEFs) from stable isotope (SI) analysis of zoeal whole-body tissue in the laboratory were 2.0‰ for δ13C and 1.9‰ for δ15N. In the field water column, diatoms dominated the nano- to micro-sized plankton, accounting for 38 to 81% of the biovolume, followed by heterotrophic protists. The trophic position (TP) estimated from amino acid-specific δ15N values for the field-collected zoeae VI was 2.1 (TPGlu/Phe) or 2.7 (TPAla/Phe), suggesting that those zoeae fed on mixtures of phytoplankton and heterotrophs including protists. Bulk SI analyses were performed for particulate organic matter (POM; proxy for phytoplankton), microzooplankton (mainly calanoid copepods), and shrimp zoeae to elucidate the diet of larvae in the water column. A shift in SI from fresh to degraded POM was determined through the incubation of field-collected POM. Based on this shift during degradation and larval TEFs, phytoplankton and their sinking detritus with heterotrophic protists were estimated to be the principal diet for those larvae residing mostly below the chlorophyll maximum layer.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Marine Ecology Progress Series, 592, pp.141-158; 2018","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Inter-Research"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3354/meps12507","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2018 Inter-Research"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"01718630","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"16161599","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Umezawa, Yu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tamaki, Akio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Toshikazu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeuchi, Seiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshimizu, Chikage"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tayasu, Ichiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-18"}],"displaytype":"detail","filename":"MEPS592_141_Supp.pdf","filesize":[{"value":"166.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MEPS592_141_Supp.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/198/files/MEPS592_141_Supp.pdf"},"version_id":"398d752f-e40b-4960-9ff4-f26d01c170e5"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-18"}],"displaytype":"detail","filename":"MEPS592_141.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"MEPS592_141.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/198/files/MEPS592_141.pdf"},"version_id":"6b276fa5-dfa2-42ed-9d3a-d97bd71a8237"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Nihonotrypaea harmandi","subitem_subject_scheme":"Other"},{"subitem_subject":"Zoea","subitem_subject_scheme":"Other"},{"subitem_subject":"Rearing","subitem_subject_scheme":"Other"},{"subitem_subject":"Diatom","subitem_subject_scheme":"Other"},{"subitem_subject":"Isotopic trophic enrichment factor","subitem_subject_scheme":"Other"},{"subitem_subject":"Amino-acid-δ15N-based trophic position","subitem_subject_scheme":"Other"},{"subitem_subject":"Phytodetritus","subitem_subject_scheme":"Other"},{"subitem_subject":"Protists","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":"Phytoplankton as a principal diet for callianassid shrimp larvae in coastal waters, estimated from laboratory rearing and stable isotope analysis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Phytoplankton as a principal diet for callianassid shrimp larvae in coastal waters, estimated from laboratory rearing and stable isotope analysis"}]},"item_type_id":"2","owner":"2","path":["51"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-30"},"publish_date":"2019-07-30","publish_status":"0","recid":"198","relation_version_is_last":true,"title":["Phytoplankton as a principal diet for callianassid shrimp larvae in coastal waters, estimated from laboratory rearing and stable isotope analysis"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:20:12.742539+00:00"}
