Species composition of ichthyofauna and the structure of the fish communities in the Irminger Sea and adjacent waters were studied in May–July 2003–2011. In total, 115 species/taxa have been registered in the catches; they belong to 47 families and 18 orders. The data on their abundance and biomass are presented. The vertical, spatial, and interannual variability of the species composition and the structure of ichthyocenosis have been described.
