What is caviar

Caviar” is an energetic and nutritious food that its consumption is very low due to its very high price in our country.

This product is exported and currently, 85% of world consumption is related to Europe, America, and Canada. Today, this precious food is less popular. But knowledge of its valuable properties is necessary for the people of a producing country.

What is the meaning of the word caviar?

Caviar is Persian and from the word khagavar means small egg.

Caviar is known as black pearl.

On the eastern shores of the Caspian Sea, especially the shores of the Turkmen port (from Hasanqoli Bay to Miankaleh), Golestan province is the most important place for sturgeon fishing, where only half of Iran’s caviar is extracted.

Caviar is the unfertilized egg produced by the ovaries of the female sturgeon.

Basically, sturgeon is called estrogen. The value of these fish, in addition to meat, is due to their eggs, which are known as black pearls.

It takes between 12 and 16 years to get caviar from a fish. In the past, sturgeon were anesthetized with a plastic hammer, and then the caviar was taken out and the meat was sold. But today, by cesarean section, some of the eggs are removed from the belly of the fish.

And some are left to regenerate in the belly of the fish and the fish are returned to the sea. This method can be done up to 6 times for each fish.

Sturgeon, or sturgeon, belongs to the sturgeon family, a species of aquatic species that dates back several hundred million years to the Jurassic Age.

Hence, sturgeon are called living fossils of the world, which have survived to this day along with phylogeny evolution.

These fish are divided into 27 species and subspecies in the world, of which 6 species live in the Caspian Sea.

The value of sturgeon is not because of the use of their meat but because of their eggs, which are known as caviar or black pearl.

There are different types of caviar such as golden, red and black caviar, of which black caviar is of considerable value.
