The label was something like: Russian caviar, Augustovskaya, Astrakhan.
Russia imposed a blanket ban on the export of black caviar in 2002, and later on commercial sturgeon fishing. Since then black caviar have been produced by state fish farms where sturgeon are reared. The only caviar available for purchase legally today is from fish raised on fish farms.
