Industry, electric power, utilities, agriculture, mining, construction, shipbuilding, transport and fishing have a constant anthropogenic impact on the Northern Dvina river basin. Identification and qualitative assessment of factors of anthropogenic impact on the fish fauna of the Northern Dvina river basin within the boundaries of the Arkhangelsk region is the aim of the research. Open data of public authorities on anthropogenic impact and scientific publications are the basis for the research. The main factors of anthropogenic impact on fish fauna have been identified. The impact is multifactorial. Fishing reduces the number of fish populations, and economic activities in the water area and the banks of the water body worsen the conditions of the fish habitat. This leads to a change in the parameters of fish populations. Reconstruction of existing wastewater systems and construction of new ones, as well as the introduction of restrictions on the use of forest resources in the coastal zone are directions for reducing the anthropogenic impact.
