The Tuapse Oil Refinery (part of the Rosneft Oil Refinery complex) released over 35,000 Black Sea salmon fry into their natural habitat. The event was part of the company's project to restore the population of this rare, endangered species.

Black Sea salmon was a commercial fish until 1955. However, due to unregulated fishing and poaching, its population declined sharply. Today, Black Sea salmon are under state protection. Conservation and reproduction of brown trout are possible only through special programs for raising young fish in artificial conditions and subsequently releasing them into the wild.

At the request of the Tuapse Oil Refinery, juvenile brown trout were raised at a trout hatchery in water from artesian wells. The fry were fed special food with vitamins and probiotics to boost their immunity. After reaching a weight of 1.5 grams, the fry were given salt baths to facilitate their adaptation to seawater. Before release, each fish weighed approximately four grams.

Release sites for the fry are determined by representatives of the Federal Agency for Fisheries and the Azov Research Institute of Fisheries and Oceanography, taking into account water composition, food supply, temperature, current, and distance from the sea. The river water temperature must match the temperature of the water in which the fish were reared. The release site is ten kilometers from the sea; the fry will cover this distance in two months. At sea, the salmon will gain weight and, after two to three years, return to their release site to spawn.

Previously, in 2020-2021, the company organized the release of fry in batches of 6,000 and 12,000. Environmental campaigns to restore the brown trout population are yielding positive results. Cases of fish weighing up to 500 grams returning to the rivers have already been recorded.

Preserving the environment for future generations is a key focus of Rosneft's strategy. The company and its subsidiaries are implementing a number of comprehensive programs to preserve biodiversity and natural resources in the regions where they operate, and are also committed to environmentally friendly production and minimizing their environmental impact.

In addition to releasing the fry, the Tuapse Oil Refinery also participates in environmental campaigns, holding cleanup days, including in the area around the Kiseleva Rocks natural monument. The company's volunteers also conduct environmental education among young people.
