Caviars are the cured eggs of a large male fish that you can consume. Caviars are generally quite expensive. However, they are well known as a seafood delicacy. They are the eggs of various varieties of sturgeon fish. The most common types are beluga and sevruga. The other varieties include hackleback, sterlet, osetra, and Kaluga. Caviars have a slimy texture and are salty tasting, making them pop in the mouth. Therefore, people use them as a topping on plain crackers, toast, cucumber sticks, and garnish. However, people generally serve them in small quantities.
During a certain period, people consumed too much caviar. Then, the Soviet Union fell apart, reducing its control of beluga caviar. As a result, overfishing and market exchanges rose. Thus, these species grew endangered over time. That is why the United States has prohibited the import of this delicacy.
