| Abstract | This paper investigates the abundance and distribution of Pleuragramma antarcticum larvae by size class in the Dumont d’Urville Sea from 2004 to 2010. 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. | ||||||||||||
