Nornickel replenishes Yenisey with valuable fish

August 16, 2022

In order for fry to survive in high water, many conditions should be met.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Whitefish, grayling, sturgeon, muksun fry are regularly released into the Yenisey by Nornickel divisions. More than 11 000 sturgeons and almost 130 000 whitefish fry recently swam into the river near the village of Atamanovo.

In June, two Nonickel enterprises – the Norilsk Support Complex and the Polar Transportation Branch – released 40 000 grayling fry into the Yenisey.

The juveniles were reared at the large Maltat fish farm, with which Nornickel has been working since 2016.

In recent years, the Nornickel companies group program to preserve and maintain the wildlife biological diversity and increase species has been mainly associated with sturgeon. So, two years ago, more than 73 thousand fry were released into the Yenisey. Juveniles were raised at the Norilsk fish hatchery.

In 2020, more than 130 000 grayling fry were released into the Yenisey. Nornickel spent almost 3.5 million rubles for these purposes.

In order for fry to survive in large water, they have to weigh at least one gram. And during the transportation of juveniles from the mainland, the main thing is to carefully check the temperature of the water: it should match the temperature in the reservoir where the fish will live.

Earlier, scientists expressed concern that the Yenisey record shallowing this year could lead to a decrease in the number of fish. Also, they plan to replace imported salmon in Russia with domestic ones, and Taimyr char takes root well in aquaculture on the mainland: they want to grow valuable northern fish for sale.
