Scientists conducted studies of commercial fish populations in the rivers of the Taimyr Peninsula with Rosneft's support
09 January 2025
With the support of RN-Vankor (a subsidiary of Rosneft), scientists of the Central Siberian State Natural Biosphere Reserve under a grant project assessed the state of populations of the main commercial fish species living in the rivers of the Taimyr Peninsula in the north of Krasnoyarsk Krai.
Studies of the most widespread fish species - northern pike, burbot and broad whitefish, which are the main fishing species of the indigenous peoples of the North, were conducted in the basins of the Yenisei, Pyasina, Kheta and the mouth of the Agapa rivers. 
The burbot was the most stable and resistant to changes in environmental conditions.
The expedition resulted in over 100 samples. Micronucleus analysis was chosen as the key technique for assessing the status of the Taymir’s ichthyofauna. Cytogenetic study helps to precisely assess the degree of environmental impact on living organisms, revealing mutagenic changes of biological species in case of aggressive influence in their habitats. The data obtained indicate low strength or complete absence of stress factors in the habitat of commercial fish. The state of populations does not cause concerns.
The study of commercial fish populations is of great importance, including for the indigenous peoples of the North, for whom fishing is an integral part of their traditional way of life. In addition, as part of the grant project, the scientists conducted a survey of residents of Volochanka settlement and representatives of the family-clan community community ‘KOU-KYUN’. The results of the survey showed that the quantity of fish caught, as well as its quality, remained unchanged and fully satisfy the needs of local residents.
For reference:
The results of a grant competition to support scientific research of practical importance for the Taymyr’s Dolgano-Nenets Municipal District of Krasnoyarsk Krai were summarized at the EcoArctic forum organized by RN-Vankor.
The purpose of the contest is to contribute to the solution of socially significant tasks for the territory of the indigenous peoples of the North, the development of scientific knowledge about the territory, the preservation of its biological diversity, and the support of the traditional way of life of the local population.
The winners of last year's grant competition presented projects to study the population of one of the oldest animals on the peninsula - the muskox, to assess the status of the main commercial fish species in the Taymyr's water bodies, and to create a unique textbook for the territory's schoolchildren “Taymyr's Northern Reindeer”.
