Over 2,500 sturgeon species have been released into the Danube River in Odesa to help restore the population, as the species is currently facing extinction. Factors such as hydraulic engineering, river regulation, intensive fishing, poaching, and Russian aggression have contributed to the decline of sturgeons, leading to their inclusion in the Red Book of Ukraine. The stocking was carried out by the Odesa sturgeon complex and was initiated by the World Nature Fund WWF-Ukraine, which has been involved in sturgeon fish preservation in Ukraine for over five years.
