From the Guardian – Ban on trade in wild caviar as sturgeon stocks plunge
Chaos following the collapse of the Soviet Union, as well as the growing involvement of the Russian mafia and pollution, have been blamed for a massive rise in poaching and a precipitous decline in stocks. Numbers in the Caspian Sea are thought to have fallen 90% in 30 years and slightly less in the Black Sea and major rivers. The fish are also found in smaller quantities in Bulgaria, China, Iran, Romania and North America.
I blame Reagan. Without glasnost this never would have happened!
