Caviar is a very cultural food, very popular and popular in Europe, America and the Middle East, and now the country is also beginning to contact and like this special food, the taste is very powerful, the following to share with you a detailed analysis of caviar.

Caviar is a food full of energy, very delicious.

Caviar is made from the eggs of sturgeon and is one of the most expensive products in the world. Caviar comes in red, black, and gold colors, with black being more nutritious.

Sturgeon is a rare fish, belongs to the sturgeon order of fish, is the world's most expensive kind of fish. Sturgeon enjoys the reputation of "living fossil in the water" because this fish has existed for millions of years.

Some of these fish are said to date back to the Jurassic era. During the time of vertebrates such as dinosaurs and fish, sturgeoniformes could be found in all waters of the Northern Hemisphere.

But the passage of time and other factors, such as climate change, have caused their range to shrink.

Today, sturgeons are found in the Caspian Sea, the Sea of Azov, the Ural River, the Black Sea, and sporadically in Europe and the United States.

But the main living waters of the sturgeon are in the Caspian Sea, the largest inland lake in the world.

According to statistics, 90% of the world's sturgeon population is concentrated in the Caspian Sea due to its favorable location.

There are more than 20 species of sturgeon in the world, and the five most important are the Beluga sturgeon, Persian sturgeon, Russian sturgeon, Beluga sturgeon, and the glistening sturgeon, which live in the Caspian Sea. Sturgeons are suitable for living in the deep sea because of their fast swimming speed.

The sturgeon has a long body that narrows from the head to the tail, a small head with a large body and long whiskers is another characteristic of the sturgeon.

Sturgeons are usually 1 to 2 meters long, but some sturgeons, such as the great white sturgeon, are up to 6 meters long, and some weigh more than 1,000 kilograms.

Sturgeons have five rows of raised bones with beautiful colors and stars on each row, and have black, gray, white, and yellow bodies, which are part of the wonders of the ocean.

Most sturgeon are spawning fish, and their fertilization process takes place by chance and in fresh water. This means that fish in this group migrate to turbid and fast-flowing freshwater rivers in order to spawn and do so.

These eggs are deposited on water plants or small rocks in the riverbed, and as the water flows over them, sperm drifting in the water combines with them to fertilize them, turning them into larvae and eventually into roe.

Given the different species of sturgeon, some migrate to the ocean and some to slightly salty lake water as well as brackish lakes.

The importance of sturgeon relative to other fish is due to the fact that caviar is made from their eggs, which are known for their black pearls.

Caviar is the unfertilized eggs of sturgeon, so adult sturgeon play an important role in the quality of caviar.

Sturgeon mature at a longer age than other fish, between 8 and 18 years old, depending on the species of sturgeon and the region where they live.

Of all sturgeons, the greater white sturgeon has a longer age of maturity than other sturgeons, ranging from 12 to 18 years of age due to differences between females and males.

Natural resource conservationists and staff can better and more effectively protect the growth of these fish by understanding this. For example, by knowing the age of maturity of sturgeon, more can be done to breed them in captivity and help conserve marine resources by reproducing the young.

At the same time, marine experts and activists can also artificially breed and raise sturgeon through breeding ponds, and today, due to the popularity of eating sturgeon and their caviar, the production and sale of sturgeon, caviar, and their related products is a highly lucrative and thriving trade.

The sturgeon is the largest sturgeon in the Caspian Sea, but its population is declining dramatically, and this sturgeon-like fish is also the largest fish in the world's freshwater lakes.

The Beluga is the best of the sturgeons in terms of caviar quality.

Caviar made from the eggs of a large white sturgeon in Iran can reach more than 100 kilograms, and it is worth mentioning that a 1,400-kilogram sturgeon, which is more than 100 years old, was caught in Iran.

The Persian sturgeon is another sturgeon that lives in the southern Caspian Sea. It has previously been considered a subspecies of the Russian sturgeon.

But today, due to artificial breeding and its increased numbers, it belongs to a separate group of fish, is larger than the Russian sturgeon and is also better from the point of view of caviar quality.

Persian sturgeon is the second most valuable sturgeon in terms of nutritional value. Persian sturgeon also has more colors than other sturgeon. Iranian caviar is one of the most famous and popular caviar in the world.

Another sturgeon in the Caspian Sea is the Russian sturgeon. Most live in the northern part of the Caspian Sea, but there are also sizable numbers of Russian sturgeon in Iranian waters, which is the southern part of the Caspian Sea.

When spawning, it enters the Safed and Gurgan rivers along with the Persian sturgeon.

The fruit-bellied sturgeon is a rare fish in the Caspian Sea. In the past, sturgeon were also found in the Black Sea and the Aral Sea, but they belong to a species of fish that is becoming extinct due to various reasons, including overfishing.

The sturgeon population in the waters of Russia, Azerbaijan*** and Turkmenistan is almost extinct, and the sale of its caviar is banned.

Harvesting of the fruit-bellied sturgeon in Iran to protect its reproduction has been placed on the IUCN Red List of Threatened Species by environmental organizations. Over the past years, millions of juvenile fruit-bellied sturgeon have been bred in captivity and put into the Caspian Sea to help increase the population of this fish.

The smallest sturgeon in the Caspian Sea is the flamboyant sturgeon, whose caviar is the cheapest type of caviar due to its small size and quality. But in terms of nutritional value it is no different from any other sturgeon.
