Only a few species of Antarctic fishes, most of which inhabit near-bottom waters, occur on a wide-spread scale.
From the investigations that were carried out in 1975-89 from the R/V Profesor Siedlecki, it was determined that 14 species of fish are widespread, all of them belong to two families (Channichthyidae and Nototheniidae). This paper presents the results of investigations of the distribution of these fish species with respect to the density of their occurrence and identifying sets in particular regions.
