UMMC subsidiary commemorates anniversary of Revda with carp introduction

Ural Mining and Metallurgical Company (UMMC) subsidiary Sredneuralsky Copper Smelter oversaw the introduction of approximately 8,500 young carp into Revdinsky Pond on Wednesday as a way of commemorating the 280th anniversary of the Sverdlovsk city of Revda.

Prior to their release into the pond, the white carp were grown at the nearby Reftinsky fish farm. Sredneuralsky officials waited until the carp grew to between 1.2-2.3 ounces each before introducing them to the pond's ecosystem, ITAR-TASS reports.

Before being fully released into the water, the fish must spend the next week in a special 529-square foot cage to better acclimate them to their new habitat. The cage is equipped with machines which will slowly adjust the oxygen in the water to the levels naturally found in the pond to prevent shock. After the incubation period, the fish will be able to freely move about Revdinsky pond and feed off the pond's native duckweed and algae.

The species of carp introduced to the ecosystem will reach full maturity in three to five years and have a high chance of surviving the shifts in temperature and short-term food shortages which characterize the seasonal dynamics of Revdinsky Pond, according to ITAR-TASS.

UMMC subsidiaries have been cultivating fish for local aquatic ecosystems since 2011 as a function of their environmental responsibility programs.

In the last four years, UMMC companies have released a total of two million whitefish into regional bodies of water including Revdinsky Pond, the Chusovaya River and the New Mariinsky reservoir. UMMC's carp-related environmental programs receive partial sponsorship funding from the Sverdlovsk regional government, ITAR-TASS reports.
