A total of 10 bottom trawls of 30 minutes of duration between 227 and 889 m depth were carried out along two transects respectively located in Kapp Norvegia (71°30'S-10°30'W) and north of Halley Bay (73°20'S-20°20'W) during the cruise ANTARKTIS XIII/3, conducted on board the R/V Polarstern in the frame of the research program CA-EASIZ of the Alfred Wegener Institute for Polar and Marine Research (Germany). The qualitative analysis of the catches showed a high fish species diversity (50 species belonging to 12 families) and the presence of three different fish assemblages related to depth. The assemblage of shallower waters has its bathymetric limit in the shelf breaking and is mainly composed of species belonging to the families Artedidraconidae, Bathydraconidae, Channichthyidae and Nototheniidae. The deep assemblage is associated to the slope and is numerically dominated by Macrouridae, Muraenolepididae, Bathylagidae, Mycthophidae and Paralepididae. Overlapping with these two assemblages there is a third one occupying the transitional zone between the shelf and the slope which is mainly constituted of Rajidae, Zoarcidae and Liparididae. The quantitative analysis of the catches did not provide a clear picture neither on the distribution of fish abundance nor on the relative importance of the different families in the composition of fish assemblages in the region. The apparent differences observed between the Kapp Norvegia and the Halley Bay regions in the relative abundance of fish families by depth might be due in part to geographical variations, though this possibility could not be assessed given the low sampling level carried out during the cruise.
