According to the definition presented in some valid sources, ” caviar is the processed eggs of the female fish of sturgeon family “. This definition of reliable source proves that the processed eggs of other fishes like Carp, Trout, Tuna or any other fish is not caviar .
With rapid decrease of the sturgeon populations in natural habitats, the Convention of the International Trade of Endangered Species of Wild Flora and Fauna ( CITES ) , included the sturgeon species in the list of endangered species in 1998 and with the continuation of the severe decrease of the fish population, finally banned commercial fishing of caviar fish and global trade of products derived from them , especially caviar.
After declaration and execution of this ban some local farms were stablished for production of caviar in different parts of the country. They started harvest of caviar since some years ago and introduced the product to the market.
