<b>Abstract</b>— <p>This paper presents a relevant list of fish species and fish-like vertebrates and their current taxonomic status. They both are resulted from the multi-year studies in the freshwater bodies in the Murmansk region and analysis of published data. The paper also includes data on the distribution of some species. The studies have revealed 27 species of cyclostomes and fish, including prevalent species of salmonids (10 species), that currently occur in the water bodies of the region. Some species (Atlantic sturgeon, European freshwater eel, northern whitefish and white salmon) are not included in this list, for the reason that the data on these species, was derived from their occasional occurrence and captures. Some invasive species (rainbow trout, common carp and Siberian sturgeon) are also not included in the list since their naturalization remains unproved. The taxonomic status of whitefish, one of the species representing the ichthyofauna in the Murmansk region, also remains unclear. The reason is that its distribution area, that has been considered typical of <i>Coregonus lavaretus</i> before, is limited to some lakes in Western Europe, and this species was excluded from the list of freshwater fish of Russia.</p>
