Beluga caviar is caviar consisting of the roe (or eggs) of the beluga sturgeon Huso huso. The fish is found primarily in the Caspian Sea, which is bordered by Iran, Azerbaijan, Kazakhstan, Russia, and Turkmenistan. It can also be found in the Black Sea basin and occasionally in the Adriatic Sea. Beluga caviar is the most expensive type of caviar, [1] with market prices ranging from $7,000 to $22,000/kg ($3,200 to $10,000/lb). [2] [3]
The beluga sturgeon is currently considered to be critically endangered, causing the United States Fish and Wildlife Service to ban in 2005 the importation of beluga caviar which originated in the Caspian Sea and Black Sea basin. In 2006, the Convention on International Trade in Endangered Species (CITES) suspended all trade made with the traditional caviar-producing regions of the Caspian and Black Seas (Beluga, Ossetra and Sevruga), (Azerbaijan, Bulgaria, China, Iran, Kazakhstan, Romania, Russia, Serbia and Montenegro, Turkmenistan, and Ukraine) due to the producing countries' failure to apply international regulations and recommendations. [4] Caviar from Iran is exempted from the ban. Iran is considered by CITES to practise effective conservation and policing of its fisheries. [5] In January 2007, this ban was partly lifted, allowing the sale of 96 tons of caviar, 15 percent below the official 2005 level. [6] CITES maintained the 2007 quotas for 2008, drawing criticism for doing little to protect the declining sturgeon population. [7]
The beluga sturgeon can take up to 20 years to reach maturity. The fish harvested for caviar are often nearly 900 kg (2,000 lb). The eggs themselves are the largest of the commonly used roes, and range in color from dark gray (almost black) to light gray, with the lighter colors coming from older fish, and being the most valued.
The most expensive caviar is "Almas", a golden caviar produced by very rare female albino sturgeon between 60 and 100 years old, which swims in the southern Caspian Sea near Iran where apparently less pollution exists. Very few of the albino variety are left in the wild since the lack of melanin is a genetic disorder that only affects a few members of the species. A kilogram (2 lb 3 oz) is regularly sold for £20,000 (USD 22,594.00). [8] Any additions by producers diminish the value of the roe, and the caviar usually reaches the market without any additions or processing whatsoever.
In 2005, the United States made it illegal to import beluga caviar and beluga sturgeon into the country, because of the animal's endangered status. However, caviar from beluga hybrid species are still for sale in the country. [9] Many other countries allow for the import and export of beluga sturgeon caviar, as the fish has started making a comeback in recent years. Widespread farming and conservation efforts have allowed wild populations in the Caspian to redevelop.
In July 2016, Sturgeon Aquafarms in Bascom, FL became the first and only facility in the world to obtain a permit exemption for the trade in beluga sturgeon and its caviar in the USA. [10] Since 2017, Sturgeon Aquafarms has assisted in beluga sturgeon repopulation efforts across the world by providing over ~160,000 fertilized beluga eggs to the Caspian Sea region. [11]
As with most caviars, beluga is usually handled with a caviar spoon made of mother of pearl, bone, or other nonmetallic material, as metal utensils are said to impart an unwelcome metallic taste to the delicate roe. [12] Beluga caviar is usually served by itself on toast, unlike other less expensive caviars that can be served in a variety of ways, including hollowed and cooked new potatoes, on blini, or garnished with sour cream, crème fraîche , chopped onions, or minced hard boiled egg whites. These items can, however, be served with beluga as palate cleansers.
Sturgeon is the common name for the 28 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus, and Pseudoscaphirhynchus. Two species may be extinct in the wild, and one may be entirely extinct. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. A Maastrichtian-age fossil found in Morocco shows that they also once lived in Africa.
The American paddlefish is a species of ray-finned fish. It is the last living species of paddlefish (Polyodontidae). This family is most closely related to the sturgeons; together they make up the order Acipenseriformes, which are one of the most primitive living groups of ray-finned fish. Fossil records of other paddlefish species date back 125 million years to the Early Cretaceous, with records of Polyodon extending back 65 million years to the early Paleocene. The American paddlefish is a smooth-skinned freshwater fish with an almost entirely cartilaginous skeleton and a paddle-shaped rostrum (snout), which extends nearly one-third its body length. It has been referred to as a freshwater shark because of its heterocercal tail or caudal fin resembling that of sharks, though it is not closely related. The American paddlefish is a highly derived fish because it has evolved specialised adaptations such as filter feeding. Its rostrum and cranium are covered with tens of thousands of sensory receptors for locating swarms of zooplankton, its primary food source. The only other species of paddlefish that survived to modern times was the Chinese paddlefish, last sighted in 2003 in the Yangtze River in China and considered to have gone extinct no later than 2010.
Roe, or hard roe, is the fully ripe internal egg masses in the ovaries, or the released external egg masses, of fish and certain marine animals such as shrimp, scallop, sea urchins and squid. As a seafood, roe is used both as a cooked ingredient in many dishes, and as a raw ingredient for delicacies such as caviar.
Caviar is a food consisting of salt-cured roe of the family Acipenseridae. Caviar is considered a delicacy and is eaten as a garnish or spread. Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea. The term caviar can also describe the roe of other species of sturgeon or other fish such as paddlefish, salmon, steelhead, trout, lumpfish, whitefish, or carp.
The beluga, also known as the beluga sturgeon or great sturgeon, is a species of anadromous fish in the sturgeon family (Acipenseridae) of the order Acipenseriformes. It is found primarily in the Caspian and Black Sea basins, and formerly in the Adriatic Sea. Based on maximum size, it is the third-most-massive living species of bony fish. Heavily fished for the female's valuable roe, known as beluga caviar, wild populations have been greatly reduced by overfishing and poaching, leading IUCN to classify the species as critically endangered.
The kaluga, also known as the river beluga, is a large predatory sturgeon found in the Amur River basin. With a maximum size of at least 1,000 kg (2,205 lb) and 5.6 m (18.6 ft), the kaluga is one of the biggest of the sturgeon family. Like the slightly larger beluga, it spends part of its life in salt water. Unlike the beluga, this fish has 5 major rows of dermal scutes and feeds on salmon and other fish in the Amur. They have gray-green to black backs with a yellowish green-white underbelly.
The lake sturgeon, also known as the rock sturgeon, is a North American temperate freshwater fish, one of about 25 species of sturgeon. Like other sturgeons, this species is a bottom feeder and has a partly cartilaginous skeleton, an overall streamlined shape, and skin bearing rows of bony plates on the sides and back.
Ossetra caviar is one of the most prized and expensive types of caviar. It is obtained from the Ossetra sturgeon, which weighs 50-400 pounds and can live up to 50 years.
Sevruga caviar is one of the highest priced varieties of caviar, eclipsed in cost only by the Beluga and Ossetra varieties. It is harvested from a variety of critically endangered sturgeon fish species, that are known for their small, grey colored eggs. In eastern Europe, it is harvested from the Sevruga sturgeon, the Sterlet sturgeon and the Siberian sturgeon, which are native to the Caspian Sea and the surrounding rivers.
The shovelnose sturgeon is the smallest species of freshwater sturgeon native to North America. It is often called hackleback, sand sturgeon, or switchtail. Switchtail refers to the long filament found on the upper lobe of the caudal fin. Shovelnose sturgeon are the most abundant sturgeon found in the Missouri River and Mississippi River systems, and were formerly a commercially fished sturgeon in the United States of America. In 2010, they were listed as threatened under the U.S. Endangered Species Act due to their resemblance to the endangered pallid sturgeon, with which shovelnose sturgeon are sympatric.
Fauna of Azerbaijan or animal kingdom of Azerbaijan refers to the diversity of various types of animals, which inhabit and populate a defined ground or water area in Azerbaijan.
The starry sturgeon also known as stellate sturgeon or sevruga, is a species of sturgeon. It is native to the Black, Azov, Caspian and Aegean sea basins, but it has been extirpated from the last and it is predicted that the remaining natural population will follow soon due to overfishing.
The Persian sturgeon is a species of fish in the family Acipenseridae. It is found in the Caspian Sea and to a lesser extent the Black Sea and ascends certain rivers to spawn, mainly the Volga, Kura, Araks and Ural Rivers. It is heavily fished for its flesh and its roe and is limited in its up-river migrations by damming of the rivers. Young fish feed on small invertebrates, graduating to larger prey such as crabs and fish as they grow. The threats faced by this fish include excessive fishing with the removal of immature fish before they have bred, damming of the rivers, loss of spawning areas and water pollution. The International Union for Conservation of Nature has listed the fish as critically endangered and has suggested that the increased provision of hatcheries could be of benefit.
The Russian sturgeon, also known as the diamond sturgeon or Danube sturgeon, is a species of fish in the family Acipenseridae. It is found in Azerbaijan, Bulgaria, Georgia, Iran, Kazakhstan, Romania, Russia, Turkey, Turkmenistan, and Ukraine. It is also found in the Caspian Sea. This fish can grow up to about 235 cm (93 in) and weigh 115 kg (254 lb). Russian sturgeon mature and reproduce slowly, making them highly vulnerable to fishing. It is distinguished from other Acipenser species by its short snout with a rounded tip as well as its lower lip which is interrupted at its center.
Huso is a genus of large sturgeons from Eurasia. It contains two species, both of which are critically endangered:
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake and sometimes referred to as a full-fledged sea. An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau. It covers a surface area of 371,000 km2 (143,000 sq mi), an area approximately equal to that of Japan, with a volume of 78,200 km3 (19,000 cu mi). It has a salinity of approximately 1.2%, about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast.
The fishing industry in Turkmenistan has been of benefit to the economy of Turkmenistan and food supply, particularly on the Caspian Sea for centuries. The fishing industry took off around 1910 in Turkmenistan but declined between 1950 and 1990, with the banning of sturgeon catching in Turkmen waters. Today, the fishing industry is developing rapidly, due to technological modernization and renewal schemes and the growth of aquaculture. Under the command of the Turkmen president, fishing facilities in the country have been reconstructed and constructed with modern industry infrastructure, particularly in the Caspian Sea 610 km coastline of western Turkmenistan in Balkan Province.
Kaluga Queen is a Chinese brand of caviar made by the caviar company Hangzhou Qiandaohu Xunlong Sci-Tech Co., Ltd. The company produces 60 tonnes of caviar annually, making it the largest producer of caviar in the world and responsible for 30% of world production. Kaluga Queen supplies caviar for 21 of the 26 3-starred Michelin restaurants in Paris.
Russian Caviar House is a Russian group of companies that grows sturgeon and sells black caviar. It is Russia's largest producer of black caviar.
The Caviar of Kladovo was a type of caviar produced in eastern Serbia. It was named after the town of Kladovo, in central Serbia, part of the Danube's Iron Gates Gorge between Serbia and Romania. Made from various fishes' roe, the caviar was granted the protected geographic designation and was considered an expensive delicacy, which was even served on the RMS Titanic. With the construction of large dams in 1972 and 1984, jointly by the two states, the fish migrating from the Black Sea upstream the Danube were prevented from reaching their old spawning areas, and production of caviar was discontinued in the 21st century.
