Earlier, at the end of June, the release of peled took place in the Mirninsky Region of the Republic of Sakha (Yakutia). More than 41,000 larvae were released into the Aanniaakh River, and from there they entered the Akhtaranda River and then the Vilyui Reservoir. Replenishment of commercial fish stocks in the reservoir is of great importance for the population with a traditional way of husbandry.

In total, for 2021 Gazprom Nedra has planned about 20 releases of juveniles of valuable commercial fish species: muksun, chum salmon, grayling, peled, and salmon in various regions of Russia. For example, it is planned to release about 90,000 juveniles of the West Siberian subspecies of Siberian sturgeon, which is on the endangered-species list of Russia, into the rivers of the Ob-Irtysh Fishery Basin by the end of summer.
