Transneft Druzhba has released sterlet juveniles into the Desna River in Bryansk District, Bryansk Region. An environmental event on artificial reproduction of aquatic biological resources was organised together with Transneft PCD.
The juveniles were transported from a fish farm, specialising in sturgeon breeding, on a vehicle with an oxygen supply system. The release of fish into their natural habitat was supervised by specialists of the Moscow-Oka Territorial Directorate of the Federal Agency for Fishery (Rosrybolovstvo), who confirmed the satisfactory sterlet condition.
The water body was replenished with about 110 thousand juveniles of valuable commercial species. The average weight of each was 2.5 g.
For juveniles to adapt to their natural habitat and settle into the river tributaries, fishing is officially prohibited for 15 days up and down bed of the Desna River within 500 m of the release place.
The environmental compensatory event on artificial reproduction of aquatic biological resources was held under Transneft’s 2019-2021 corporate programme for biological diversity preservation. During this period, more than 1.5 million young sterlet, Russian sturgeon, silver carp and wild carp replenished water bodies in regions of Transneft Druzhba presence.
