What is what fish is caviar?

Caviar is a delicacy consisting of salt-cured fish eggs, typically from sturgeon, which is a type of large and ancient fish found in freshwater and saltwater around the world. Sturgeon caviar is highly valued for its rich, buttery flavor and distinctive texture.

The most famous and sought-after caviar comes from the beluga sturgeon, followed by the osetra and sevruga sturgeon. These fish are primarily found in the Caspian and Black Seas, although overfishing and habitat destruction have led to a decline in their populations and the availability of true caviar.

In addition to sturgeon, caviar can also be made from the eggs of other fish such as salmon, trout, and paddlefish. These types of caviar are often less expensive and more readily available than sturgeon caviar, but they can still be delicious and luxurious in their own right.
