The Urals are restoring the sterlet population

Specialists from the Ural branch of the Russian State Research Center “All-Russian Research Institute of Fisheries and Oceanography” (VNIRO) together with representatives of the Lower Ob Territorial Administration of the Federal Agency for Fisheries took part in an event on artificial reproduction of aquatic bioresources.
 
From July 22 to August 15, the Tavda and Lozva rivers were systematically stocked with fish. More than 350,000 specimens of young sterlet aged one year and one year were released into their natural habitat.
 
Gradual stocking of water bodies allows young fish to better adapt to new living conditions, increases their survival rate and promotes more effective restoration of the population. A sudden release of a large number of fry can lead to overpopulation and a shortage of food, which will negatively affect their development and survival rate.
 
Sturgeon stocking is an important step in maintaining biodiversity and restoring valuable commercial fish species in the Ural rivers.
 
Reference:
 
Tavda: a large river flowing through the Sverdlovsk and Tyumen regions. It is a left tributary of the Tobol River. It is characterized by a winding channel, an abundance of floodplain lakes and a rich ichthyofauna.
 
Lozva: originates on the eastern slopes of the Northern Urals and is one of the components of the Tavda River. The river has picturesque banks surrounded by dense forests and serves as an important habitat for many fish species.
