Arranging a field base in the course of Amu Darya shovelnose sturgeons (Pseudoscaphirhynchus) conservation project in Uzbekistan to collect and keep shovelnoses before sending them to Nukus Balyk hatchery.

In 2020 Nukus Balyk fish hatchery (Nukus, Karakalpakstan, Uzbekistan) was registered as the Amu Darya shovelnose sturgeons propagation hatchery. It provided the Amu Darya shovelnoses conservation project () with a line of recirculating aquaculture system (RAS). Water in the system is refreshed from the Amu Darya river through a canal.
Creating an initial brood stock of Amu Darya shovelnose sturgeons is the first step towards their propagation and conservation efforts.

According to our experience Amu Darya shovelnose sturgeons (Pseudoscaphirhynchus kaufmanni and Pseudoscaphirhynchus hermanni) are very sensetive to specific water properties but this issue has not been studied enough yet. That's why we are especially concerned about supplying Amu Darya shovelnoses with the water from the Amu Darya river where they live in the wild. The Amu Darya river water is always muddy. But the muddy water is not suitable for recirculating systems. So we have to let the muddy water settle down. Than we fill the pool aimed at keeping shovelnoses with the settled Amu Darya water.
