Fisheries research of the Pyasina river basin

At the end of April 2020, the largest man — made disaster in the Russian Arctic occurred-a diesel fuel spill in Norilsk. Oil products on the Ambarnaya river got to the lake. Pyasino (source of the river of the same name). To determine the extent of damage to the aquatic ecosystem of the Pyasina basin, it is necessary to know the nature and direction of previous research in the fisheries field. The aim of the work is to analyze the available open source publications in the field of fisheries research in the Pyasina basin. The history of ichthyological and hydrobiological studies of the Pyasina river basin (a large watercourse on the Taimyr Peninsula) is considered. Information is provided that the basin of this river is poorly studied in terms of fisheries due to its location beyond the Arctic circle. The chronology of fisheries research from the Foundation of the Yenisei ichthyological laboratory (Krasnoyarsk) in 1908 to 2020 is given. It is noted that the greatest interest in studying the basin of this river is shown in connection with the development of the Norilsk mining and metallurgical combine and the organization of the Federal state budgetary institution «United Directorate of Taimyr reserves». The role of individual scientific organizations in the study of water ecosystems of the Pyasina river basin is shown. The most significant contribution to the fisheries survey of the river basin was made by the Siberian scientific fisheries station (now the Krasnoyarsk branch of the all-Russian research Institute of fisheries and Oceanography), MSU, TSU. The publications of employees of these organizations contain materials on the study of phytoplankton and zooplankton, zoobenthos, their production characteristics, the biology of a number of species, the Stingray of larvae, features of the development of semi-passable ichthyofauna, materials on the genetic features of individual populations of whitefish, biological and morphological features of whitefish and char fauna, fish Parasitology, the content of polyunsaturated fatty acids, and others. Information is provided on the number of zooplankton species and forms, including 28 forms. It is shown that the composition of the ichthyofauna of the river basin to date, 38 species of fish are known.
