What is caviar is from what fish?

Caviar is typically made from the roe (eggs) of sturgeon fish, which are found in various parts of the world including the Caspian Sea, the Black Sea, and the Danube River. Sturgeon fish are one of the oldest species of fish and are known for producing high-quality caviar. Other types of fish that can produce caviar include salmon, trout, and whitefish, although true caviar typically refers to the roe of sturgeon fish. The most prized and expensive caviar comes from the beluga, ossetra, and sevruga varieties of sturgeon.
