Mines Nordgold released in the river of Yakutia 100 thousand. Peled fry
The gold mines Taborny and Gross, which are part of the international company Nordgold, this year released 100 thousand fry of peled into the Vilyui reservoir of Yakutia. In 2019, enterprises plan to release more than 420 thousand fry.
Malkov peled specially ordered mines are grown annually at Chernyshevsky fish farm in Yakutia. This is the only plant in the region that is engaged in artificial breeding of fish. Young fish are grown in conditions as close as possible to natural ones in water taken directly from the Vilyui reservoir. The cultivation process takes about six months. By the time the fish is released into the pond, each of the fry weighs 0,005 grams, and reaches a length of three to four mm.
According to the press service of Neryungri-Metallic LLC, the larvae hatch by the method “Dry-fertilization”, when individuals are caught. Fertilized eggs are delivered to the plant, where it is incubated in special devices. Six months later, the larvae hatch from the eggs. At the same time, the incubator maintains the inflow of fresh water from the Vilyui reservoir, and a constant temperature regime of 0,4-0,6 degrees. For fry important physico-chemical indicators of the environment. If they are released into another water, then the mortality rate is very high. The release of fish is monitored by specialists from the Lensky Territorial Department of the Federal Agency for Fisheries, the main fish farmer of Chernyshevsky hatchery, fish farmers and authorized representatives of the Taborny and Gross mines.
“We produce young fish annually. The number of fry is agreed by state authorities. It is determined by the intensity of the impact of our enterprises on aquatic biological resources. That is, the mines compensate for their environmental impact. The ecosystems of Yakutia are unique, and we are aware of our responsibility for the impact on the nature of the region. Therefore, among other measures, we support the populations of naturally-living fish, the biological diversity of rivers in the region of our presence, ”said Sergey Tinnikov, environmental engineer (ecologist) at Taborny Mine LLC.
