Samples were collected between Dumont d'Urville station and the Mertz Glacier Tongue onboard the RV l'Astrolabe for studying the inter-annual and spatial distribution of fish larvae and the TRV Umitaka Maru for looking at life stages vertical distributions. The seabed depression adjacent to the Mertz Glacier Tongue and in Commonwealth Bay hosted high abundances of small P. antarcticum larvae, while larger larvae were found in lower abundance and further offshore. We found that canyons, sea ice, stability of the water column and temperatures are important features for determining suitable areas for young larvae., Dumont d’Urville Sea(東南極)で2004から2010年にかけて,コオリイワシの分布様式をサイズ・クラスごとに調べた。Dumont d’Urville 基地からMertz Glacierにかけて「RV l’Astlorabe」によって採集されたサンプルは年変動と空間分布の解析に,「TRV海鷹丸」によって得られたサンプルはおもに発育段階ごとの鉛直分布の研究に用いられた。Mertz Glacier近傍の海盆とCommonwealth Bayには小型の仔魚が多く分布していたが,大型の個体はより沖合に分布していた。海底谷の存在や海氷の量,水柱の安定性や水温が仔魚の最適な分布域を決定している。}, pages = {225--238}, title = {Spatial distribution and inter-annual variations in the size frequency distribution and abundances of Pleuragramma antarcticum larvae in the Dumont d'Urville Sea from 2004 to 2010}, volume = {5}, year = {2011} }
