Caviar

CAVIAR

Of the twenty-six species of sturgeon found in the world, those most valued are the four that dwell in the Caspian Sea, including, from largest to smallest in size, the beluga (Huso huso ), the osetra or Russian sturgeon (Acipenser gueldenstaedti ), the sevruga or stellate (Acipenser stellatus ), and the sterlet (Acipenser ruthenus ). Each is appreciated for the quality and flavor of its roe (fish eggs), otherwise known as caviar (ikra, ). Although they vary in the intensity of their saltiness and flavor, all Caspian caviars have a subtle, buttery taste. Because of the damage induced by the Volga River's cascade of hydroelectric dams, which originally were built without fish ladders for anadromous fish such as the Caspian sturgeons, and subsequent overfishing in the sea itself, the populations of the Caspian sturgeons have plummeted since 1960. Thus connoisseurs have recommended that caviar lovers redirect their palates to the roe of more abundant fish species, such as the cheaper, but tasty American sturgeon, until the Caspian stocks can rebound. With the major decline of their numbers in the Caspian Sea, sevruga and osetra are being farm-raised in ponds in Europe.

Belugas, which produce the best and most expensive caviar, are the largest freshwater fish in the world, typically weighing more than one ton, measuring 27 feet (9 meters) long, and living for 150 years. The largest on record weighed 4,350 pounds (1,973 kilograms). Beluga eggs are large, bluish gray, and slightly sweet. The caviar is best when it is fresh.

Osetra sturgeon measure up to 9 feet (3 meters) in length and weigh up to 90 pounds (200 kilograms). Osetra caviar is brown in color and stronger in flavor than beluga caviar.

The sevruga sturgeon is smaller still, and yields the smallest eggs. Sevruga caviar possesses the strongest flavor of all the caviars. Because of this, it is cheaper than beluga or osetra, but still quite good.

The exceedingly rare sterlet is the smallest of the Caspian sturgeons, measuring a little under 50 inches (2 meters) long, weighing 7 pounds (16 kilograms), and living on average to the age of 22 years. Sterlet, or imperial, caviar was once the most prized fish roe of all. The eggs are small-grained and golden in color. Valued also as a food species, the sterlet has been fished almost to extinction.
