Moscow Zoo
Many sturgeon species have been bred in captivity and this often forms the basis for restocking the wild populations. In the 1980s there were attempts of doing this with the Amu Darya sturgeon. Although some progress was made, captive breeding ultimately failed because the embryos died. Since 2010, the Moscow Zoo (together with various Russian institutes and officials of Tajikistan and Uzbekistan) has attempted to start a breeding program for the Amu Darya sturgeon, but as of 2015 it has not succeeded.
