Scientists have successfully used biotechnology to artificially reproduce the Azov-Black Sea shemaya fish, restoring its population in the Don River basin and removing it from the Red Book of Russia. The project, supported by the government of the Rostov Region, has shown high efficiency and may be replicated in other regions. The Ministries of Agriculture of Russia and the Rostov Region are considering allowing amateur fishing for shemaya in the Don River basin. Shemaya is a valuable commercial fish found in the Azov, Caspian, Black, and Aral Seas.
