Caspian stellate sturgeon

There were numerous projects for improvement of the fishery productivity of the Aral Sea due to introduction of mass species of zooplankton, zoobenthos, and fish. In the 1940-1950S the fries of the Caspian stellate sturgeon, bullhead, and Baltic herring were released into the sea. After this the consumption of zooplankton increased sharply, while its resources shrank. 

The new inhabitant of the Aral Sea, i.e., the Caspian stellate sturgeon, propagated extensively however, it was not fished at this time.
