Purpose. To conduct a comprehensive analysis of literary sources on the current state of Danube salmon populations and the prospects for its conservation in Europe and Ukraine. One of the most popular measures for restoring the population is stocking water bodies with fish seeds grown in artificial conditions. The goal of artificial reproduction is to restore the reproductive contingents of fish populations to provide better environmental services and preserve the biodiversity of aquatic ecosystems.

Findings. A review of scientific publications is presented, which highlight the state of Danube salmon populations and the prospects for its conservation in Europe and Ukraine, and information on the presence and abundance of Danube salmon in places of traditional biotopes and reproduction in artificial conditions is shown. The problem of restoring the qualitative and quantitative characteristics of Danube salmon populations is more than important, and restoring their abundance within the natural range is currently possible, to a large extent, thanks to the implementation of targeted fishery measures for artificial reproduction using broodstock created under controlled conditions of aquaculture enterprises.

Practical Value. This review will be useful for scientists, postgraduates, students as well as for ichthyological research and carrying out work on the reproduction of valuable fish species in specialized farms of the Carpathian region.

Keywords: holovach, holovatytsia, hlavatka, biodiversity conservation, population, artificial reproduction.
