#ARCTIC. #SIBERIA. THIS IS TAIMYR. Some of the Putorana char fry, which are reared at fish factories in the Leningrad region and in Krasnoyarsk, have reached a length of 15 centimeters. Scientists have measured the content of polyunsaturated fatty acids – it has already reached the volume of wild salmon content.
Approximately half of the Putorana char caviar collected in nature successfully turns into growing fish. These are the intermediate results of the project supported by the Project Office for the Development of the Arctic (PORA) on breeding Taimyr fish in aquaculture, which is unique in its nutritional properties.
Now, 2440 juveniles of Putorana charr are reared at the Federal Breeding and Genetic Center for Fish Breeding in the village of Ropsha in the Leningrad region and at the Maltat fish factory near Krasnoyarsk (top photo). The fry hatched from the eggs collected during expeditions to lake Sobachje in Taimyr, fertilized and incubated at the Norilsk fish factory of the Federal State Budgetary Institution Glavrybvod.
The Salvelinus Char Monitoring and Artificial Reproduction program in lake Sobachje is held with the financial support of PORA (Arctic Development Project Office). Within the framework of the program, several expeditions took place, in which employees of the Siberian Federal University, the Institute of Biophysics of the Siberian Branch of the Academy of Sciences and the Yenisey Branch of the Federal State Budgetary Institution Glavrybvod caught char spawners in the wild for caviar production and artificial insemination.
The eggs, fertilized in the field, were taken to the Norilsk hatchery for further incubation, and then sent to fish factories in other parts of Russia.
Lake Sobachje, which is located in the Taimyrsky Dolgano-Nenetsky District of the Krasnoyarsk region, attracted the attention of specialists several years ago, when researchers from the Siberian Federal University and the Institute of Biophysics of the Academy of Sciences discovered Arctic char in the lake waters with a record content of long-chain polyunsaturated fatty acids of the omega-3 family. These substances are responsible for the health of the cardiovascular and nervous systems, the youth and beauty of the skin, the prevention of degenerative changes in the brain and the prevention of obesity.
A group of scientists led by corresponding member of the Russian Academy of Sciences, professor Mikhail Gladyshev analyzed the content of useful substances in Putorana char and found out that the content of omega-3 polyunsaturated fatty acids in this breed of fish is much higher than in sardines and other types of marine fish that were previously considered the most useful.
However, commercial fishing of rare fish in the reserved lake is impossible. The main goal of the project is to introduce char from lake Sobachye into aquaculture in order to be able to artificially grow Taimyr fish with unique nutritional properties. This requires the collection of eggs from several wild spawners in several stages to ensure sufficient genetic diversity and create a so-called replacement broodstock.
Earlier, we told how scientists organized the expedition to the north of the Krasnoyarsk region to study char. In the future, they want to serve this fish on the table of every Russian family.
