The Caspian area is the world’s main producer of
wild caviar (83% in 2003) and supplies the four
largest markets, the European Union, United States,
Switzerland and Japan. The construction of several
hydroelectric power plants and dams along the Volga
river significantly altered the flow of water into the
delta and destroyed about 90 per cent of the sturgeon’s
spawning grounds, which can be as far as several
hundreds of kilometres upstream. With high levels
of water pollution, sturgeons also suffer from various
diseases. According to the survey of the Food and
Agriculture Organization, reported data from Caspian
states excluding Iran indicate that the wild sturgeon
catch has dropped from an average of about 22 000
tonnes a year in the 1970s to about 373 tonnes in 2008.
