   Caviar is defned as a precious fish product made from roes of the sturgeon family by treating with food grade salt. The most famous caviars are derived from wild harvested sturgeons in the area of the Caspian Sea: Beluga (Huso huso).  Historically, it is known as “black gold”, and the name originally comes from a Persian word meaning "Spawning".      In fact, persians are said to be the first consumers of caviar as a source of food. It is believed to be a God’s gift for the people residing on the south coast of the Caspian Sea.  The sea, mostly on the southern side, is the main reservoir of about 90% of caviar in the world. Over the past few decades, due to an ever-increasing demand for caviar, overfishing and water pollution, there have been a sharp decline in available wild sturgeon stocks, resulting in more aquaculture caviar production by sturgeon rearing farms especially using the sea water in Iran.
