To the history of pacific salmon research in the Khabarovsk branch of VNIRO

The article presents an overview of publications by the staff of the Khabarovsk branch of the State Scientific Center of the Russian Federation FGBNU VNIRO (KhabarovskNIRO) over the entire period of its existence (1945–2023) devoted to the study of Pacific salmon. Of the 1,5 thousand scientific papers, 450 (29,1%) were published on this group of fish. In the 1950–1980s and 2000–2010s, the works were dominated by studies on the population dynamics (27,1%) and biology of salmon (24,5%), their artificial reproduction (17,6%), biology, trophic links and food supply of their young (9,2%) (a total of 78,4% of works). In 2020–2023, against the backdrop of a sharp decline in the number of Pacific salmon in the Amur River basin, within the framework of the Second Amur Ichthyological Expedition, the main efforts to study them were focused on studying fisheries and developing measures to regulate it (24,4%), methodological developments (24,4%), biology research (17,8%), modeling population dynamics (15,6%) and surveying spawning grounds, assessing the number of spawned producers (11,1%). It is concluded that further progress in developing a deeper understanding of the biology of Pacific salmon and the mechanisms of their abundance, as well as developing effective measures to regulate the fishery, will be facilitated by creating a database based on GIS technologies using both archival data and large-scale materials on salmon obtained in recent years as part of innovative scientific research using AI, GIS, UAVs, and the NetCor-3 hydroacoustic complex. In addition, it is necessary to involve in the analysis the extensive data of the Second Amur Ichthyological Expedition on zooplankton, benthos, other fish, the overall productivity of the Amur basin ecosystem, and the dynamics of its hydrological regime. Such an integrated approach will increase the number of analytical works and, in particular, prepare a summary of the Amur salmon based on the results of the expedition.
