Sturgeon species

Sturgeon species

Sturgeon or Sturgeon, a family of tuscan fishes, are among the rare aquatic species dating back to the Jupiter age of several hundred million years ago, and therefore caviar fish are called the living fossils of the world that have survived along with the phylogenic evolution to this day. . These fishes 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 due to the use of their flesh, which is due to their eggs, known as black caviar or pearl.

Caviar has a variety of varieties, such as golden and red and black caviar, with black caviar of considerable value.

The Caspian Sea alone accounts for 93% of the caviar and sturgeon crops.

There are also five species of the world’s preeminent sturgeon fish that live in the sea, which are respectively “elephant fish”, “sturgeon of Iran”, “sturgeon gold (chalbaesh) or Russian”, “fish of the spit”, ” Ozon fish “.

Sturgeon species

Elephant fish

The largest fish of Iran’s interior water, ranked first in terms of caviar quality, with samples of about 1,400 kg and over 100 years of age.

It spawns once every two or three years and rises between the ages of 14 and 17 and is ranked

the most expensive fish and caviar in the world due to the best caviar.

It has an area of ​​one and a half meters to more than four meters in length, with record fishing in Iran of 980 kilograms and 120 kilograms of caviar.
Gharehran or Persian sturgeon

One species of sturgeon is considered independent, but previously it was considered as a subfamily of Russian fish.

This sturgeon is “Qahrabrun”, which means “Black Nose” to Turkish, which is worth the second place. Currently, artificial multiplication has surpassed the perspective of a large number of Russian species. It is larger than the Russian species and has a sturgeon superiority to him, apparently, somewhat similar, though a darker color with white pigments that extends to his nose, distinguishes it from the appearance of the Russian black duck .

It weighs 60 to 130 kilograms in length, ranging from 1 meter to more than 2 meters in length between 12 and 14 years old.

Russian duck or chubby

Amongst the species of sturgeon found in all parts of the Caspian Sea, the caviar is also called the so-called Golden, which is of the third rank, and reaches the age of 12 to 16 years old. It is about 1 to 2 meters in length and weighs 60 to 100 kilograms.

• Caviar fish is usually a migratory fish that flows through the ocean to the coast of Iran

and lays in rivers in the Caspian Sea. With a lifespan of 30 years, it is lightweight and has a plenty of use.

In terms of value, it is ranked fourth.

With a length of more than 1 meter and a weighted weight, it rises between the age of ten and the age of 14 and reaches the age of anatomy.

Ozon Brown Fish (Dracula)

One of the smallest species of sturgeon in Iran is the mistaking of all sturgeon species called ozonum.

From the qualitative point of view, it is the last rank, because it uses a smaller, less expensive caviar. In terms of artificial proliferation,

it has a burning problem, and its number is also declining in natural conditions.

In the translation of his name is a long nose.

At the age of 8 to 12, he will be matured. The cemetery is 1-1.5 meters and weighs lighter compared to other fish in the Caspian Sea.
