Iranian technicians wash caviar before refrigeration in a sterile preparation room at Pishghadam organization near Zibakenar in Gilan province, 225 miles (365km) northwest of Tehran, on November 1, 2006. A recent U.N. decision bans the export of caviar from the Caspian Sea for all countries except Iran because the stocks of sturgeon in the Caspian have dropped an estimated 90 percent due to over fishing.
