40,000 sterlet fingerlings were released into the Oka River near Murom within preparation of the territory for construction of M-12 Highway section, namely, "New exit to Moscow Ring Road from the Federal M-7 "Volga" Highway on section of Moscow Ring Road – 60th kilometer (bypasses of Balashikha, Noginsk), Moscow Region". The highway will further connect Moscow with Kazan, and further with Yekaterinburg.
Fingerlings are released according to the requirements of the legislation, together with Moscow and the Territorial Administration of Oka of the Federal Agency for Fishery.
Weight of one sterlet fingerlings is about 2.5 grams, and length is about 3 cm.
This is not the first releasing of fingerlings. When constructing bridges and discharge facilities, road workers release fingerlings into large water bodies within the environmental legislation. Their species composition depends on the territory and capabilities of local fish farming enterprises. In recent years, the valuable fish species (sturgeon, sterlet) are preferred.
Avtodor State Company has been replenishing aquatic biological resources for the sixth year in a row.
In 2014, more than 300 sterlet fingerlings were released into the Oka River within preparation of the territory for construction of the Central Ring Road (CRR);
In 2015, more than 540,000 white sturgeon fingerlings were released in preparation for construction of the Central Ring Road and M-11 Neva, as well as almost three thousand salmon fingerlings;
In 2016, about 55,000 one-year-old Atlantic salmon fishes were released in preparation of the territory for M-11;
Within reconstruction of M-4 Don in Rostov Region, more than 400,000 bream fingerlings were released; withing reconstruction of M-1 Belarus in Moscow Region — more than 93,000 sterlet fingerlings were released; In 2017, more than 192 white sturgeon fingerlings were released in Tver Region within construction of M-11; In 2018, before the reconstruction of the bridge over Dzhubga on M-4 in Krasnodar Krai, more than one thousand sturgeon fingerlings were released; In 2020, more than eight Black Sea salmon fingerlings were released in Krasnodar Krai.

When transporting fingerlings, special conditions are observed that is a low temperature of water saturated with oxygen. Therefore, they are transported in special vehicles at night so that the water does not heat up in the sun.
Scientific institutions, which are responsible for the artificial reproduction of valuable fish species, preservation of their biodiversity, and assessment of the ecological situation of fishery water bodies, transport fish to the place of release.
