Caspian Sea The Caspian Sea is the world’s most massive supply of caviar. The Caspian Sea is known to be the largest inland body of water on the planet, and it is located between Asia and Europe. It has a surface area of 371,000 km² (143,000 sq. mi.) The Sea is formed from the remnant of the ancient Paratethys Sea.
The Caspian Sea is bordered by Russia, Kazakhstan, Turkmenistan, Azerbaijan, and Iran. After the Caspian Sea, the next most massive supply of caviar is from the Black Sea. In terms of production, China happens to be the most significant producer of caviar. About 60% of the world’s output of caviar is from China. I hope you find this useful.
