Information about fish species composition from region near the Ukrainian Antarctic Station «Akademik Vernadsky» (Argentine Islands, Antarctic Peninsula) during wintering 2007-2008 is presented. The quantitative indexes of different species fishes and the analysis of their dominant groups were studied. New fishes subdominant was registry with help our researches. Trematomus bernacchii was subdominant in the previous years, but during our researches Notothenia rosii prevailed already. Biological and morphometrical analyses of two groups Notothenia coriiceps from the Meek-Penola Channel and near the west coast of Grotto Island are conducted. It is exposed, that these two groups of fish species divided, probably, on the different population. Somatic indexes did not show considerable changeability, except for hepato-somatic. Individuals of both groups’ species of fish had the low indexes of adiposeness and fatness.
