Detailed analyses of their lipid class and fatty acid compositions were carried out. P. antarcticum showed a pronounced ontogenic lipid accumulation with increasing size. Larvae displayed a dominance of polar lipids (83% of total lipids) and low percentage of triglycerides (7%). Conversely juveniles showed an increasing accumulation of triglycerides (up to 72.4%). The fatty acid composition of polar lipids remained rather stable between stages with 22:6n−3 and 20:5n−3 as dominant contributors. The relatively minor ontogenic changes, e.g. increase of monounsaturated and decrease of C18 polyunsaturated fatty acids, may reflect the influence of differences in diet. Triglycerides showed that all three age classes are well segregated in term of fatty acid composition. Larvae triglycerides are characterized by significant percentages of 16:0, 20:5n−3, 20:6n−3 and to a minor extent 18:4n−3, which suggest a prymnesiophyte based diet. Juveniles are characterized by larger percentages of C20:1 and C22:1 acids, considered as markers of Calanus type copepods. The increasing contribution of 18:1n−9 in the triglycerides of the older juveniles suggests a gradual and increasing shift from a copepod dominant diet to an euphausiid dominant diet. Fatty acid trophic markers pattern suggests a shift from a phytophagous and omnivorous diet for larvae to a carnivorous diet for juveniles.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2008年夏季、Dumont d’Urville Sea(東南極)で採集されたコオリイワシの脂質クラスと脂肪酸組成を調べた。コオリイワシでは、明瞭な体サイズの増加に伴う脂質の蓄積が認められた。仔魚期には、脂質のうち極性脂質が主要で(全脂質の83%)で、トリグリセリドの割合は小さいが(7%)、稚魚期にはトリグリセリドが72.4%まで増加した。極性脂質の脂肪酸組成は22:6n-3と20:5n-3が主要で、仔魚期と稚魚期でほとんど同じだった。トリグリセリドについては、3つの年級で脂肪酸組成が明瞭に異なっていた。仔魚は16:0、20:5n-3、20:6n-3が主要で、わずかに18:4n-3が占める。稚魚ではC20:1とC22:1の割合が大きく、稚魚後期には18:1n-9が増加する。このことから、仔魚ではprymnesiophyteを基本とした餌を食べ、稚魚期にはCalanusタイプのカイアシ類、さらに稚魚後期には餌がオキアミ類にシフトしていることを示している。 ","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID(NAID)","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110008608353","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2010.12.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.12.003","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Mayzaud, P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Chevallier, J."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tavernier, E."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Moteki, M."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koubbi, P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mayzaud, P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Chevallier, J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tavernier, E.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Moteki, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koubbi, P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Pleuragramma antarcticum","subitem_subject_scheme":"Other"},{"subitem_subject":"Age class","subitem_subject_scheme":"Other"},{"subitem_subject":"Lipid composition","subitem_subject_scheme":"Other"},{"subitem_subject":"Fatty acid trophic markers","subitem_subject_scheme":"Other"},{"subitem_subject":"Pleuragramma antarcticum","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Age class","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lipid composition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fatty acid trophic markers","subitem_subject_language":"en","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":"Lipid composition of the Antarctic fish Pleuragramma antarcticum.
