Stable isotopes (δ13C and δ15N) and diet contents were used in order to study dietary shifts between fish larvae and juveniles. All specimens had low δ13C values (<−24‰), a main characteristic of high-Antarctic pelagic species. Fish larvae showed differences in both carbon and nitrogen ratios when compared with juveniles. Muscle δ15N values showed a difference of one trophic level ( 3‰) between larvae (6.7‰) and juveniles (9.7–10.0‰) and a trophic position of tertiary consumers. Diet content analyses (stereomicroscope and scanning electron microscopes) indicated that larvae are omnivorous, feeding on phytoplankton (mainly diatoms) as well as on zooplankton species. A positive relationship between δ15N values and size was found and indicated a carnivorous diet for older specimens.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"安定同位体と消化管内容物の解析から，コオリイワシ（ノトセニア科）の仔魚期から稚魚期にかけての餌組成の変化を明らかにした。すべての標本は，High-Antarctic
