Salmonids will soon appear in the polar lake Imandra - Nornickel will take care of this

06 december 2022

In the Arctic, ichthyologists from the Karelian Scientific Center of the Russian Academy of Sciences supported by the Kola Mining and Metallurgical Company, which is a subsidiary of PJSC MMC Norilsk Nickel in the Murmansk Region, are carrying out experimental breeding of salmon fish species on Lake Imandra with an area of almost 900 square kilometers. This follows from a report by a Murmansk television company, TV-21
The essence of the experiment is that this time the scientists decided to use an off-farm method of stocking the lake, bypassing artificial pools for feeding juvenile fish and instead placing eggs taken from the broodstock directly into the river, where “natural incubation occurs, the fry hatch, and in the future “homing” is instilled in fish - a natural reaction, a return to the point where the fish was born,” says Denis Efremov, researcher at the Karelian Scientific Center of the Russian Academy of Sciences, Candidate of Biological Sciences, ichthyologist. 
This project was initiated by the Kola Mining and Metallurgical Complex, which is part of Norilsk Nickel and, as noted in the report, has been helping scientists to unlock the potential of water bodies in the Murmansk region for several years, to preserve and study biodiversity. 
For a long time, Nornickel has been running a programme to breed and release valuable fish species into water bodies to replenish their populations. Since 2016, the company has been cooperating with the Maltat fish breeding farm to release over 1,200,000 Siberian sturgeon fingerlings into water bodies. In accordance with the Support Agreement signed with the indigenous peoples of Taimyr, the Company invests in a fish breeding farm on the peninsula. In addition, the Group’s entities release aquatic biological resources in line with the national regulation.
